Who is a Full Stack Developer?

full stack development

We've all heard about all-in-one platforms or tools. But have you heard about an all-in-one person? Well, that is who a full stack developer is. If you are considering becoming one or hiring one, we are here to help you out. Don't worry if you have no basic knowledge about this profession because we will cover it all. 

 

So who is a full stack developer? 

 

To understand who is a full stack developer, you first should understand what full stack development is. Web development divides into two main branches: front-end development and back-end development. 

 

Front-end development is dealing with the stuff that is visible to the website visitor. It is the side of your website or application with which your users interact. The back-end development, on the other hand, is not visible to the user. It deals with more technical aspects of website maintenance. 

 

Front-end development and back-end development together make the full stack development. Accordingly, a full stack developer is someone equally skilled in both front-end and back-end development. It usually takes many years of experience to become a good professional in this field as it requires extensive and broad knowledge of web development. 

 

Now when we have a general understanding of what the profession is, let's jump to the next section. If you're wondering how to become a good professional, then you might crumble upon the question: 

 

What is a software stack? 

 

To keep it simple, if you need to run an application, you need a group of different components to make it happen. Your application might perform very diverse tasks, but it needs a single infrastructure to take care of it all. That list of components makes up the software stack. 

 

If you want to become a good expert, you should know some of the famous software stacks. Of course, you don't have to learn them all. You should decide which one you need the most depending on your personal preferences, the field you are working in, or the company requirements. But here is the list of most popular software stacks: 

 

LAMP stack 

 

LAMP is an acronym for Linux, Apache, MySQL, and PHP. It is a very popular stack for web applications and websites. One of the most famous apps using the LAMP stack is Facebook. 

 

MERN stack 

 

MERN stands for MongoDB, Express, React, and Node.js. So it is basically based on JavaScript technologies. MERN stack also is widely used in the development of web applications. 

 

MEAN stack 

 

Finally, the last one in our list which is recently becoming more and more popular is the MEAN stack. It is an abbreviation for MongoDB, Express, Angular.js and Node.is. 

 

Another vital question that we have not covered yet is: 

 

What Does a Full Stack Developer Do?

 

Let's say you've learned the main software stacks and found your dream job. What's the use of it if you cannot answer your grandma's question of "What do you do though?" To make sure you don't get confused, we have the answer for that too. 

 

However, it is not very grandma-friendly. 

 

When hired, you might be required to do; 

 

  • The translation of user requirements for the overall architecture

  • The management of the projects, along with the cooperation with the client 

  • Writing back-end code with Java, PHP, Ruby, Python, etc. 

  • Writing a front-end code using JavaScript and HTML 

  • Optimization of the written code 

  • Troubleshooting of the applications and coming up with solutions 

And much more. 

 

Make sure you don't confuse your profession with the software engineer, though. 

 

What’s the Difference between Full Stack Developer and Full Stack Engineer?

 

Your job has a more wide approach. You work with the project more holistically. They design a complete prototype of the product and deal with various aspects of it.  A full stack engineer, on the other hand, usually engages only with one phase. They might be responsible for a single step of the development project. 

 

But if you have to deal with so many different phases of the project, what skills should he have to do so? Here is a list of full stack developer skills that you need to master to become a good professional in your field. So, if you are wondering how to become a great expert, learn these skills: 

 

What Skills Do You Need to Become a Full Stack Developer?

 

The full stack developer skills you need start with the: 

 

Front End 

 

A good full stack developer should have a solid knowledge of front-end development. It includes the knowledge of HTML, JavaScript, CSS3, and so on. You should also be familiar with third-party libraries such as Angular, jQuery, and ReactJS. 

 

Back End 

 

As we have already mentioned, as a full stack developer, you will not only be responsible for the user interface and interactive part of the application but also the back-end logic. So you need to learn server-side programming languages such as Python, Ruby, Java, and others. 

 

Database and Cache 

 

You should also regularly collect the data stored in your client's computer system. The data can be very different. You might deal with the products, financial information, some private data, and so on. 

The most popular databases are SLQServer, Redis, Oracle, and others. 

 

Basic design skills 

 

Yes, we know it. You might think why you should learn design skills if you are getting hired as a developer. Well, of course, design skills are not mandatory, but they are desired for many companies. 

 

The reason for it is that you are going to deal with front end development. So if you want to make the website attractive, you should have some basic designing skills. 

 

It does not mean you should take an in-depth design course. Not at all. Just learn the basic principles of design, and get yourself familiar with UI & UX designing. It will give you an enormous advantage over your competitors. 

 

Web architecture 

 

As a good employee, you are expected to have an in-depth understanding of web architecture. You will be working on very complex web and software applications, so you should know how to build them from scratch. It includes the knowledge of code structure, file categorization, knowledge of the database, and so on. 

 

VCS

 

VCS stands for the version control system. Version control refers to the systems responsible for monitoring the changes in programs, large websites, documents, and so on. 

 

If you are working with a team, then to make your workflow easier, use VCS. It improves the collaboration between the developers so that when one changes something in the file system, it is transparent and visible to others. 

 

Other skills 

 

Finally, do not forget about soft skills. No matter how good of a professional you are, if you cannot communicate with your team efficiently, it will be challenging to work with you. So, improve your communication skills and make sure you are a leader and a team player at the same time. 

 

Also, do not forget about time management skills. Companies do not love when you miss deadlines and come up with excuses. So to not disappoint them, learn how to manage your work to finish all the tasks on time. 

 

Full stack developer salary 

 

Finally, we will answer the most exciting question. How much will you earn? Depending on your skills and experience, expect your  salary to be in the range of $97.000-150.000 per year. 

 

Sum Up 

 

If you want to become a good full stack developer, there are a lot of skills you should master. However, at the end of the day, you will be a demanded professional who has multiple jobs offers all at once! There is no doubt that you will not regret your decision. So start learning today to enjoy the results tomorrow. 

 

Good luck!

How to Find Skilled Developers in 2021

The technology industry continues to develop by jumps bounding with numerous technical innovations all around the world. Despite the Covid-19 pandemic, many tech companies are still in great demand for developers. Tech companies are always hiring cybersecurity engineers, DevOps, and many other engineers due to the high number of phishing attacks and severe digital competition amid the pandemic. 

Research suggests that hiring developers has never been this effortless with so many conference apps being available.

However, finding developers may seem quite complicated if you do not know how many opportunities you have in the contemporary digital world. From social media to customized platforms, you can find any developer you need:  freelancer, in-house, full-time, or part-time.

Remember, it’s best if you combine several strategies while searching for developers to come up with the best catch out there.  

 

Here are some of the most popular platforms of 2021 to consider while looking for skilled developers online.

 

LinkedIn

LinkedIn is a social media website mainly built for professional networking. As a small business, you can use the platform to find a developer among a wide range of candidates. 

What do you need to do?

Build your company’s profile page

Have both your current and former employees connect through the page

Search for developers using keywords (JS, Java, Python)

Send personalized invitations (Hello John…)

Remember, your current employees play a significant role in whether you will o have a good catch or not.




Quora

 

Just like Linkedin, Quora is another great platform (though less professional) where developers love to gather and share their knowledge. The easiest way to find a developer is by searching for topics in your area of interest. For instance, you can ask a certain tech stack question and have it answered by superb software developers. 

In a word, Quora hosts many gifted professionals, however, keep in mind that most Quora developers work for some of the biggest companies out there like Facebook, Google, so it will be quite challenging to find full- time developers here.

You can click here to learn more about how you can use Quora for further research.

 

Developer Meetups and Forums

 

A great way to get to know and connect with developers is to look for annual conferences or meetups locally. Even though due to the Covid-19 pandemic, many meetings have been transformed into virtual reality, finding a developer and recruiting them online is still relevant and possible. 

Just keep in mind that there exist a lot of different meetup categories, such as WCIT, Pycon

make sure you attend one, which coincides with your area of interest.

 

Coding Challenge Websites 

 

Coding Challenge websites can be a great place to search for potential developers, as developers who perform well, get featured on the related sites. Just search the specific skills you need for the project, and you may even find the code the particular developer has written. 

TopCoder, Coderbyte, HackerRank, CodeChef, and even HireVue are some of the greatest websites where you can find a matching developer. Some of them publish weekly blogs that make your searching journey even easier. You can even find some awesome challenge tests on sites like HireVue to test the developers before actually hiring them.

 

Facebook Groups 

 

Another efficient way to find a developer is by joining Facebook groups of developers or freelancers based on the location or a specific tech infrastructure. Of course, it may take some time to join certain groups due to their terms and conditions, however, it is usually not a big deal to post on those groups as long as you follow their regulations. Once you are accepted to the group, take your time and engage with the community, provide value to get one. After some time, you can post about your job opportunity or outreach the desirable candidates privately and schedule interviews with them if they get thrilled about the offer. 

 

 

 

 

Freelance Platforms 

If you consider hiring a freelance developer, looking for them in a freelance platform is probably the wisest thing to do. Before starting your research, keep in mind that freelance platforms are usually grouped into two main categories: general and niche.

General includes the most well-known and widespread platforms such as Freelancer, Upwork, Guru. Among the high number of registered freelancers, you will surely find developers through these platforms. However, the major problem in general platforms is that there is no vetting of developers, hence anyone can claim to be one, while niche platforms are originally made for developers. These usually have wider and more extensive evaluating procedures, which will accelerate the process of finding the right candidate for your business.

 

Among some of the most popular niche freelance platforms, ithire.com is quite an outstanding one. The platform lets the clients track how many hours the freelancer has been working on their project by viewing the screenshots. The payment method is simplified as much as possible. Money is being paid only after the client reviews the submitted tasks so that both parties will stay satisfied.

Finally, the feature that makes Ithire a bingo is the presence of the magical project managers. The company offers highly professional project managers certified and controlled by Ithire to plan, monitor, and execute your project and of course, guide the development team. 

Sounds confusing? How does it work? 

Project managers contact the client introducing themselves and their experience. After choosing a certain pm for the project, the client can either choose the developers or leave it on the pm to decide. Either way, Ithire makes sure there is no miscommunication between the clients and the freelancer

s. This unique feature makes the realization of the project quite effective which leaves entrepreneurs highly pleased. 

Post a job and find a freelancer on ithire.com for yourself! 

 

Let’s wrap it up! 

After finding a freelancer, one may say that even more challenges emerge such as the planning and implementation of the project. However, it all starts with choosing the right team members for your project. Just like when you try to hire a long-term employee to work in your company, finding a freelancer is the same. Put some reasonable effort into finding a developer, and you will have half of the job done!

 

 



Top 5 HTML5 Tips and Trick: Major Features to Know

Want to create an attractive website? You don’t have to hire an expensive UI/UX designer for that. With HTML5, CSS and JavaScript, you have enough tools to make your website unforgettable. 

In this blog entry, we are giving you a complete HTML5 tutorial. It will help you to make your website even better! However, if you don’t have enough time, you can hire professional html5 developers on our website.

Before we jump into our HTML5 tutorial and explore the coolest HTML5 tips and tricks, let’s understand how HTML5 is different from HTML.  

 

What is new in HTML5 ? 

 

First of all, let’s take a look at the new features of HTML5 and understand in which aspects it is different from HTML. Here are some of the major factors: 

 

Audio and Video 

Storage 

Support of Web Browser 

Vector Graphics 

Usability 

 

With HTML 5, you can embed media without third-party plugins. You can also use canvas and svg to use vector graphics without additional technologies. When it comes to storage, with HTML5 you can use application cache, web storage, and web SQL database. Compare it to HTML with just the browser cache, and the advantages are visible. However, not all web browsers support the new HTML5 features. Nevertheless, HTML5 is still a preferred version as it is easy to use and has a simple syntax than HTML. 

 

Now straight to the: 

Top 5 HTML5 Tips and Tricks

Audio and Video Tags 

 

The concept of media was foreign to HTML. So one large leap that HTML5 makes is introducing us to audio and video. It is one of the fundamental HTML5 features, as it rids you from the headache of using third-party plugins. 

 

Audio 

 

Now, you can use HTML5’s <audio> tag to embed your audio directly into your website. However, currently only the most popular and recent browsers support HTML5 audio. So, it is better to use some type of backward compatibility: 

 

<audio autoplay="autoplay" controls="controls">

    <source src="file.ogg" />

    <source src="file.mp3" />

    <a>Download this file.</a>

</audio>

 

Keep in mind that Mozilla and Webkit do not get along with this new audio format yet. You will need to use the .mp3 extension for the Webkit browsers, while Firefox will ask you for a .ogg file. In short, for the time being, try to maintain two versions of your audio to avoid issues. 

 

Also, note that Safari will not recognize the .ogg format when loading your page switching to the mp3 version. 

 

Video 

 

Just like the <audio> tag, HTML5 also provides the <video> tag for embedding your videos to your website without third-party plugins. The good news is that YouTube announced that it added an HTML5 video embed for YouTube videos, which makes embedding even easier! Of course, you should make sure that your browser supports this new format. 

 

Safari and Internet Explorer 9 will support the H.264 format video, as the Flash Player can read it. However, Firefox and Opera only support the Theora and Vorbis formats. So, just like with audio, it is better to have both formats for your HTML5 videos. Here is an example of using the <video> tag: 

 

<video width="320" height="240" controls>

  <source src="movie.mp4" type="video/mp4">

  <source src="movie.ogg" type="video/ogg">

Your browser does not support the video tag.

</video>

 

 

The Canvas Element 

 

Another creative way you can use the <canvas> element is by making animations with it. With the mix of the <canvas> element and JavaScript, it is now possible to create pretty animations without needing the Flash: right from your web browser. If you want to give it a shot, here is an HTML5 tutorial for making animations with canvas

 

One thing is for sure: animations and similar visual enhancements have always attracted the attention of visitors. So if you want to take your website’s user experience to another level, you need to give it a try. 

 

Another key element of HTML5 is the <canvas> which has influenced the wide usage of Adobe Flash in many websites. You can use the <canvas elements for drawing graphics with different colors and shapes by using scripting (usually JavaScript). It is a container for visual graphics. Here’s an example of its usage: 

 

<canvas id=”myCanvas” width=”200″ height=”100″ style=”border:1px solid #000000;”>

</canvas>

 

 

Voice Recognition Feature 

 

Another cool feature of HTML5 is its voice recognition tool. With the new speech recognition API, your visitors can browse through your website using voice commands. JavaScript has access to your browser’s audio coming from speech recognition API. It can then convert the audio to text and complete the directives. Of course, this will only work if the voice is decipherable. Here’s a visual representation of the process: 

 

 

At this moment, the voice recognition feature of HTML5 is supported only by Chrome. But because Chrome has a booming 63.3 percent of market share, it is not that sad. Your voice recognition feature would be available to the majority of your visitors. It will make your website unique and help it to stand out. 

 

Here’s how you voice recognition to a text input: 

 

<input type="text" x-webkit-speech />

 

 

The Ability for Visitors to Customize Background or Text Color 

 

 

One of the coolest features of HTML5 is that you can have your customers choose the background and text color they want your website to be in. It will add an extra layer of fun to your website and will enhance the user experience. Here’s the extra code you need to add to your website to make this possible. 

 

 

<select name=”clr” onchange=”document.bgColor=this.options[this.selectedIndex].value” size=”1″>

    <br>

    <option value=”black”>black

        <option value=”orange”>orange

            <option value=”flamingred”>fuschia

                <option value=”lightyellow”>light yellow

                    <option value=”green”>green

                        <option value=”cyan”>cyan

                            <option value=”yellow”>yellow

                                <option value=”red”>red

                                    <option value=”white”>white</option>

</select>&nbsp;&nbsp;Background Color

 

<br>

<select name=”clr” onchange=”document.fgColor=this.options[this.selectedIndex].value” size=”1″>

    <br>

    <option value=”black”>black

        <option value=”orange”>orange

            <option value=”flamingred”>fuschia

                <option value=”lightyellow”>light yellow

                    <option value=”cyan”>cyan

                        <option value=”yellow”>yellow

                            <option value=”red”>red

                                <option value=”white”>white</option>

</select>&nbsp;&nbsp;Text Color

 

 

Help your visitors to enjoy your website to the fullest! 

Map Images 

We end our HTML5 features list with the map images. With this cool feature, you can make different areas of your image clickable. For instance, you can have a map of your country and link various restaurant websites to specific areas. This way, when your visitor clicks on those areas, she will be led to the local restaurant’s website! 

 

How do you do that? You simply need to mention the X and Y coordinates in the <area> element which is in the <map> element. Here’s an example: 

 

 

<h1 style="text-align:center;">The 7 Continents</h1>

 

<h4 style="text-align:center;">&#10148; Click on the dots in the image to go to a continent section</h4>

 

<map name="continents_map">

 

 <area shape="circle" coords="70,70,10" href="#north_america">

 

 <area shape="circle" coords="133,185,10" href="#south_america">

 

 <area shape="circle" coords="270,137,10" href="#africa">

 

 <area shape="circle" coords="292,44,10" href="#europe">

 

 <area shape="circle" coords="469,201,10" href="#australia">

 

 <area shape="circle" coords="374,65,10" href="#asia">

 

 <area shape="circle" coords="340,267,10" href="#antartica">

 

</map>

 

<figure style="text-align:center;">

 

    <img usemap="#continents_map" src=https://bit.ly/2bgFrvL width="600px" />

 

    <figcaption>World Map</figcaption>

Top 6 React Interview Questions and Answers for 2021

React.js interview questions may seem quite troublesome if you have not taken your time preparing for the BIG day. Slowly but steadily, React is becoming one of the most influential Javascript frameworks in the marketplace. Therefore the demand for React js developers is increasing daily. 

So, if you desire to find a job as a front-end developer or find a front-end developer for your project, get prepared with these React Interview Questions beforehand and achieve your objectives! 

 

Generic React Interview questions

 

What is React?  

React is a front-end JavaScript library developed by Facebook in 2011. Its principal purpose is to grow compound and interactive web and a  mobile User Interface. It is based on a component approach and helps to expand reusable UI components. 

The main features of React js are 

Virtual DOM

Server-side rendering 

Unidirectional data flow

React JS makes it altogether easy to write User Interface test cases. React conveniently incorporates other frameworks such as Angular, Meteor. 

It is essential to keep in mind that React is just a library rather than a fully developed framework. The library is wealthy, but don't worry, you have plenty of time to do your research.



What is JSX?

JSX stands for JavaScript XML. JavaScript XML is a file used by Reach employing the full potential of JavaScript with HTML-like syntax. The HTML file is accessible to understand, have a look below. 

 

render(){

    return(     

          

<div>

             

<h1> Hello World from Edureka!!</h1>

 

         </div>

 

    );

}

Browsers cannot read a JavaScript XML since they only read JavaScript objects. Therefore, JSX files get converted into a JavaScript object by JavaScript transformers such as Babel for browsers to read it. 

 

After such general questions, the interview will turn into a more technical discussion.

 

 

Is there any difference between Real DOM and Virtual DOM?

 

Yes, there certainly is. Real Dom is slow and creates a new DOM every time an element gets updated. Virtual DOM is faster and updates JSX if an element gets updated. Real Dom can directly update HTML, while Virtual Dom cannot, however Virtual DOM manipulation is much easier compared to Real Dom expensive manipulation. 

So, we can say that Virtual Dom is originally the copy of the Real DOM. It is a light JavaScript Object, a note tree that lists the elements, the attributes and content as Objects. The Virtual DOM works in three easy steps. 

Whenever any fundamental data changes, the entire User Interface gets re-rendered in Virtual DOM representation.

The difference between the previous representation and the new one is calculated. 

After the calculatioReact.js interview questions may seem quite troublesome if you have not taken your time preparing for the BIG day. Slowly but steadily React is becoming one of the most influential Javascript frameworks in the marketplace, hence the demand for React Certificate is increasing daily. 

So, if you desire to find a job as a front-end developer, prepare with these React Interview questions beforehand and achieve your dream!

 

What is Props? 

Props stand for properties in React. They are purely fixed read-only components that are always passed down from the parent to the child components and never back. A child component can never send a prop back to the parent. It guarantees the unidirectional data flow of React.

 

What is a State?

 

States are the core feature of React components. They are a source of the data and are mutable, unlike props. In a word, states directly determine components rendering and behavior. 

 

There is an underlying difference between Props and States. Props acquire initial value from parent components, while states do not. Meanwhile, the parent component cannot change its value in States, but it can in Props. The same goes for the child component as well. Both States and Props set the default insight component. The insight component is unchangeable in Props, while it can undergo mutation in States.

 

Describe the React js lifecycle

React defines components as classes or functions. Components defined as classes provide more features. You need to extend React.Component, to define a component as class. Render is the only method that must be defined in a React.Component subclass. All the other methods are optional. Have a look!

 

class App extends React.Component {

render() {

return (

<div className="App">

<h2>Hellow World!</h2>

</div>

);

}

}

Each component has several “Lifecycle Methods” that can override to run codes throughout the entire process. 

 

Lifecycle methods are divided into four classes: 

Mounting

Updating

Unmounting

Error handling

 

Mounting includes constructor(). Constructors are used for two main reasons:

Starting a local state by assigning an object to this.state.

Binding event handler methods to an instance.

 

static getDerivedStateFromProps() is called right before the render method. This method exists in rare usage cases when the state depends on whether props will change over time. This method is fired on every render, in contrast to UNSAFE_componentWillReceiveProps, which only fires when the parent causes a re-render and not as a result of a local setState.

 

render()

The render method is the only required method in a class component. When it gets called, it examines this.prop and this.state and returns one of the following types. The render function should not change the component state. It should return the same function every time it is invoked.  

The render function does not interact with the browser, but if you need it to interact, simply perform your work in componentDidMount() or the other lifecycle methods instead.

 

componentDidMount()

ComponentDidMount() is supplicated after a component is mounted. This method is a good place to set up any subscriptions. However, in that case, you should unsubscribe in componentWillUnmount(). SetState() can immediately be called in componentDidMount(), which will trigger another rendering. However, it will happen before the screen is updated by the browser. Therefore, the users won't see that the render has been called twice. 

 

shouldComponentUpdate()

ShouldComponentUpdate() is used to let React know if the state or props current change has affected the component’s return or not. The default behavior must re-render on every state change.

When shouldComponentUpdate() returns false, componentDidUpdate(), UNSAFE_componentWillUpdate, render() are not called. However, React may later treat shouldComponentUpdate() as a hint rather than a directive and returning false may still result in a re-rendering of the component.

 

shouldComponentUpdate()

ShouldComponentUpdate() is used to let React know if a component’s return is not affected by the state or props current change. The default behavior must re-render on every state change. 

When shouldComponentUpdate() returns false, componentDidUpdate(), UNSAFE_componentWillUpdate, render() are not called. However, React may later treat shouldComponentUpdate() as a hint rather than a directive and returning false may still result in a re-rendering of the component.

 

getSnapshotBeforeUpdate()

getSnapshotBeforeUpdate() enables your component to acquire some information from the DOM before it changes, passing any value returned by this lifecycle as a parameter to componentDidUpdate().

componentDidUpdate()

componentDidUpdate() is called immediately after updating occurs. This method is not called for the initial render.  ComponentDidUpdate() can be used for operating the DOM when the component has been updated. You can also do network requests as long as you compare the current props to previous props. 

Unmounting

This method is invoked when a component is being removed from the DOM:

componentWillUnmount()

componentWillUnmount() is called immediately before a component is unmounted and destroyed. 

Emergency cleanups such as invalidating timers, canceling network requests, cleaning componentDidMount() subscriptions should be performed straight away. 

SetState() should not be called in componentWillUnmount() because the component will never be re-rendered. Once a component instance is unmounted, it will never be mounted again.

Error Handling

Error Handling Methods are invoked when there is an error during the lifecycle methods, in the construction of any child component, or during rendering. 

static getDerivedStateFromError()

This lifecycle is called when a descendant component throws an error. It receives the error that was thrown as a parameter and should return a value to update state.

GetDerivedStateFromError() is called during the “render” phase, so side-effects are not permitted. To have side-effects permitted use componentDidCatch(). 

With the componentDidCatch(), the lifecycle is supplicated after a descendant component throws an error. It receives two parameters:

error- an error appears

info - An object with a componentStack key containing information about which component threw the error.

ComponentDidCatch() is called during the “commit” phase, so side-effects are permitted. It should be used for things like logging errors.

All in all, you will have to focus on both basic interview questions and more technical ones such as React component questions, React Redux, and Router Interview questions to pass the stage. Don’t stress much, take your time, and go for it. 

Good luck!!

 

 

How to Secure WordPress Website: A Guide to Website Security

One of the main arguments they bring against WordPress is its lack of security. WordPress security issues have always been a hot topic.  There are a lot of reasons for it. WordPress is an open-source platform, so it is assumed that it is also pretty vulnerable to all sorts of attacks. Plus, WordPress also relies on plugin and theme customization that anyone can do.

 

Most of the plugins and themes are designed by random developers, and there is not much control going on. Add to this the fact that WordPress is one of the most popular CMS platforms, and you will understand why it can turn into the number one goal of hackers. 

 

However, this does not mean that you should consider changing your CMS. Vice versa, WordPress became so famous for nothing. In fact, it is easy to use, flexible, SEO friendly, and has a bunch of other advantages for your websites. So what should you do? 

 

Well, you should take care of your website security instead. Don’t worry though, we have it all covered in this article. So: 

 

How to secure a WordPress site? 

 

After all of this, you might wonder: “How to make WordPress sites secure?” Well, we got you all covered! There are multiple tips you can use to improve your website security. From choosing the right hosting provider to updating your themes and plugins: we will mention all the steps you need to take for a more secure website. 

 

6 tips for improving your website security on WordPress 

 

Hosting is everything 

 

No really. If you are using shared hosting for your WordPress website, you will have to deal with WordPress security issues. The problem is that the shared hosting is using the same server and resources for multiple users. 

 

This is very risky as it means that if one of the users gets cyber attacked, it will automatically impact your website too, and it will be easier to hack you. Shared hosting usually has thousands of users on the same server, so it will cause many WordPress security issues. 

 

To avoid that, do not go for cheap hosting, but better for a reliable one. Try the managed hosting, which is way more secure for your website, as you do not share your server with hundreds of others. 

 

Moreover, managed hosting providers usually take care of the technical aspects of your hosting. This allows you to focus more on your business. So if you want to make your website secure, consider getting a reliable hosting provider that will do the hard work and protect your websites from hackers. 

 

Say no to the cracked themes 

 

We have all been there. Why give a lot of money for a premium theme if you can get a cracked one for free? This is a tempting offer, which most of the website owners might not be able to defeat. It seems like getting a nulled theme is a win-win as you get the functionality and look of the premium theme but do not pay money for it. However, you might end up paying much more. 

 

Some of the nulled themes that you installed from those shady websites might contain malicious hidden codes. These can destroy your website or remember your login credentials. So it is better to pay a little extra and legally get the premium theme you want than to put your website at risk. 

 

Plus, even if you have the legal themes, do not forget to update them. With every update, your themes and plugins become more secure. If you miss those updates, you will automatically increase the vulnerability of your website. In fact, many hackers use old plugins and themes to get easy access to your website. So make sure you don’t give them that chance. 

 

Update your WordPress 

 

Talking about updates, not only should you update your themes and plugins, but also your WordPress version overall. Every time WordPress introduces its new version, it also reveals the vulnerabilities of the previous version. 

 

So if you ignore the update and continue with the older version, you will be an easy target for hackers. That is why it is better to always use the most updated version of WordPress. 

Get an SSL Certificate 

 

The SSL (Single Sockets Layer) certificate was initially required only for ensuring security for specific activities, such as process payments. Nowadays, SSL certificates not only add a layer to your website security but also make it more SEO-friendly. The reason is that Google has recognized its importance and has moved the websites with SSL upper in the SERPs. 

 

In, In other words, today, it is pretty much mandatory to have an SSL certificate. It is especially crucial if your website deals with sensitive information (credit card numbers, passwords, personal details, etc.)

 

 If your website does not have an SSL, the data transmission from your user’s web browser to your server in plain text. It means that hackers can easily read it and hence easily take advantage of it. However, with the SSL, this information is encrypted. Thus, it makes it more difficult for hackers to read and so improves security. 

 

 

 

 

Think twice about your login credentials 

 

Let’s start with the WP-login URL. If you leave it by default, the address for logging in to your WordPress will be “yoursite.com/wp-admin.” However, if you do not change it you might be a target for brute force attacks. 

 

These types of attacks are used to get your username or password combination by continuously attempting logins. Even if they do not get your login credentials, too many failed attempts will temporarily close your access to WordPress, which certainly is not good news. To prevent this from happening, change your admin login URL or add a security question to the registration page. 

 

Also, make sure you use a strong password for your account. Now, it might seem an obvious step, but most of the owners would skip it by choosing a pretty simple password that they would not forget. It is useless to mention how insecure these types of passwords make your website. 

 

In fact, not only should you come up with a sophisticated password, but you should also, add a 2FA (two-factor authentication) to your website. This way, even if someone guesses your password, they will not be able to get into your WP account unless they have access to the 2FA you use. 

 

 

 

Consider installing a WP security plugin 

 

Finally, one of the easiest ways to get rid of the headache of WordPress security is to install a plugin that will take care of it all. In fact, without a plugin, it will take you a lot of time to regularly check your website for malware. You should also have a decent knowledge of coding to actually spot malware when you see it. Instead of all of it, you can simply install a plugin. 

 

WordPress security plugins help you take care of your website security by scanning for malware, sending you vulnerability reports, and regularly checking what is happening on your site. In short, it monitors your website 24/7. 

 

If you are wondering which plugin to use, you can try MalCare or Jetpack, both of which will keep your website safe.  

 

So, now you know how to secure your WordPress site: all you have to do is follow our six tips! Eventually, you will get a secure website and be able to enjoy your work peacefully.
