How to secure a site? Website Security Guide

Website security or how to protect a website? Some hacks happen for completely ridiculous reasons: untimely updates, weak passwords, etc. In this essential website security guide, I'll show you how to secure a website:

But more importantly, I'm going to talk about how we get started. think about the security of your websites Firstly. This way you have all the tools you need to make the right (security) decisions for your site. There will be as much information as possible, pour yourself a cup of tea or coffee and get ready.

What is site security?

While it's great that you're taking some steps to protect your website. You need to understand that site security is an ongoing process that requires periodic attention from you. Hackers are creative people, so threats are constantly evolving.

Site Security is the plan to protect your website and users from hackers and their malware. This includes understanding the components of your website, how they work together, and what vulnerabilities they have.

Once this foundation is in place, you need to formulate a comprehensive security plan to protect against vulnerabilities. This includes a series of configuration steps, implementing policies, and keeping threat information up to date.

The key to securing a website is understanding that this is not a one-time thing. Security evolves because threats evolve.

You will see in the article below that a good security plugin will do most of the hard work in terms of malware, but being careful and vigilant is what keeps a website secure in the first place.

Why is website security important?

WordPress is used by millions of people, so it's probably safe, right? Yes and no.

— Yes, because the core WordPress files are protected, and even if a vulnerability is found, it is fixed very quickly.

- No, because your site is not just the core of WordPress. It is a combination of plugins and themes that help make your site more functional, interactive and attractive. These plugins and themes enhance the functionality of WordPress, but also increase the potential for vulnerabilities. Good plugin developers will fix vulnerabilities quickly. But the danger in this regard is much higher.

How to protect your site from hackers? Action Steps

To have actionable plan To protect your website, the first step is to understand how websites get hacked. According to the following study, websites are mainly hacked in three ways:

This allocation should form the basis of how you plan to secure your site and where you should allocate more time and resources.

1. Protect your site from vulnerabilities

Hackers are constantly on the lookout for vulnerable websites. It doesn't matter if the site is big or small. They have many benefits from hacking almost any website. In our experience, more than 90% of all breaches are due to hackers discovering and exploiting a vulnerability.

Let's take a closer look at what vulnerabilities are. This is very important to understand so that you can consciously shape your website security strategy in the future.

What is a vulnerability?

Your website is made up of 3 main components: WordPress, plugins, and themes. It's all basically software, and like any software, it contains bugs that sometimes cause it to crash.

Errors can have various consequences: some of them slow down your website or cause an error when someone visits it. This is annoying and problematic, but the more serious ones allow unauthorized users (such as hackers) to gain access to your website. Such a bug is known as a vulnerability.

Types of vulnerabilities

Vulnerabilities can be characterized, as we did in the previous paragraph, as bugs in the code. However, there are a few specific types that occur more frequently than others:

Possible hacks on an unsecured website

Vulnerabilities are closely related to the types of attacks they allow and are often referred to interchangeably. The most common attacks that WordPress faces are:

What is the effect of vulnerability?

Plugins and themes are installed on several thousand sites, so the effect of this one flaw is multiplied many times over. Responsible plugin and theme developers are making efforts to close security holes in their products by releasing updates.

In fact, this is the key reason why it is recommended to choose premium plugins whenever possible. Regular software maintenance should be given maximum attention in a website security strategy. Great, that means the bug has been fixed. We're safe now, right? Well, not quite. Vulnerability discovery is a dangerous time for site owners.

What happens when a vulnerability is discovered?

Vulnerabilities are often discovered by website security researchers. They report their findings to the plugin or theme developer. As we said in the previous section, the responsible developers will be looking to fix the issue and release an update.
When the vulnerability is fixed, the site's security researcher will publish their findings. The developer released a fix to keep websites safe, right? Not really.

Hackers also read about the vulnerability and look for websites that have not updated their versions. Public vulnerabilities tend to appeal to budding hackers (also known as script kids) because they can now effortlessly use websites. They know exactly where their target is.

What should be done to protect the site from vulnerabilities?

Now I will talk about specific steps you can take to keep your website secure and safe from hackers. These steps may seem simple, but they are effective ways to keep your site secure.

1. Make backups

Backups are the most underestimated part of a site's security strategy. I can't stress enough the importance of regular backups. They are your safety net, the only thing you can rely on when things go wrong. Backups will help you quickly roll back the site to a healthy state.

2. Update plugins and themes

This may seem very obvious, especially if you've read the previous section on how important updates are. However, it's very easy to ignore the red notification on the dashboard and get on with something more urgent.

Therefore, I will repeat. Plugin developers release updates with security fixes for this. Even if you decide to delay installing updates, update the plugin at a later date, at least after reading the release notes.

3. Choose good quality plugins and themes

It is unlikely that there will ever be completely reliable software, there are key factors to consider when choosing the right plugins and themes for your website:

4. Use a firewall

There is no reliable way to stop hackers or their bots from attacking websites like yours. However, you can greatly reduce the chance by installing a firewall.

2. Protect your username and password

About 6% of the hacked websites were vulnerable to attacks due to weak passwords. This may seem like a small number compared to direct malicious activity, but it's still significant enough to get your attention.

Losing your site administrator password is like losing your apartment or car keys. With the key, the thief has complete control over your valuable possessions. Similarly, with a password, hackers have full access to your site and its information. At the moment, not even a firewall or security plugin can stop hackers from damaging your site.

The need for strong passwords is still actively promoted, but due to the difficulties involved, website users often ignore it. Before I get into the mechanics of getting a good reputation, let's answer some common questions people have about them.

How can a password be stolen?

The answer may come as a surprise: the hacker is trying to guess the password. By that I mean they try different passwords manually, but that's what bots are for. This is also known as a brute-force attack or, if the bot guesses the words, a dictionary attack.

These attacks work very well for several reasons.:

How to protect yourself from password theft

1. Use a strong password - Strong passwords use a random combination of letters, numbers, and symbols because they are hard to crack. It can take years for hacker bots to find the right password. You can try creating a strong password yourself or use a password generator.

2. Limit the number of login attempts - A good way to prevent a brute-force attack is to block intruders after several failed login attempts. This is an effective mechanism, as this type of attack consists of hacker bots repeatedly trying different passwords.

3. Implement two-factor authentication - Some services use two-factor authentication during the login process, which essentially means you need to have two (ideally) separate tokens to access your account. It is most often a combination of passwords and an expiration token, such as a pin or QR code, sent to your email or device.

4. Implement CAPTCHA protection - CAPTCHAs can only be solved by humans. They are designed to prevent hacker bots from accessing an account. You can use it to secure your site.

5. Use a firewall - Some website security firewalls also monitor malicious IP addresses globally. The firewall learns on all sites with the plugin installed. It then automatically blocks bad IPs before they try to crack your password. This, combined with the ability to restrict logins, can protect your site from hackers trying to break into your site's admin area.

3. Choose a good hosting provider

There is a tendency to blame the web host for everything that goes wrong with a website. While web hosts are usually responsible for many aspects of a website, they are rarely at fault when a website is hacked. In fact, the opposite is generally true: web hosts improve the security of websites.

Of course, there are some web hosts that play a role in compromising websites hosted on their server. This rarely happens, but when it does, it is a major incident that puts thousands of websites at risk.

4. Install an SSL certificate

Secure Sockets Layer, better known as SSL, is a security protocol that encrypts all connections to a website. Once installed, it appears as a padlock at the beginning of your site's URL.

The benefits of using an SSL certificate are as follows:

Good Website Security Practices

As I said at the beginning, website security is an ongoing practice. In this section, I will list techniques that are useful to incorporate into your overall website security strategy. Once you get into the habit of doing this, the small investment of your time and effort will pay off many times over with a secure website.

1. Change your password often — I understand that setting hard-to-guess passwords is tricky, especially since they are often synonymous with hard-to-remember passwords. We can also imagine the anxiety caused by being asked to regularly change our excellent password.

The reason is that passwords are the weakest link in security, especially if you use the same passwords for multiple accounts. Even if one site gets hacked, you can safely assume that all of your accounts are potentially compromised. Regular can also mean different things to different people. Some financial institutions, such as banks, require passwords to be changed every 90 days.

2. Check website users, track new admin users — hackers often leave administrator users so that they can regain access to the site. Therefore, regularly checking administrator users can increase the security of a website.

Secondly, the co-authors of the site may change. If a user no longer needs access, it's best to remove their access to the site. The reason is twofold:

Over time, as we build our site with new content and designs, we continue to add new users to our site. You should check these users periodically. You can follow the security rules yourself, but another user compromised will affect your site. When adding users, whenever possible, give them only the required access levels. For example, if someone only writes articles, don't give them admin rights.

3. Set up an activity log on your site Hackers do not use the core WordPress APIs to modify the website, so many of the changes they make will not be reflected in the activity log. However, they may leave traces, such as creating administrator accounts for themselves to access the site. These unexpected activities can help detect a breach. Conversely, if changes are being made by a collaborator, activity logs can help avoid unnecessary panic when you see changes made to your site.

4. Block PHP in your Downloads folder - A whole class of vulnerabilities (to be precise, Remote Code Execution) allows hackers to upload malicious PHP files to the Uploads folder. The hacker can then use it to execute any code on your site. In other words, they have complete control over your site.

The attack can be effectively mitigated if you block the execution of the PHP files in the Uploads folder. Don't worry. Blocking PHP files in the Downloads folder is safe because they shouldn't be there at all. The Uploads folder is where you store your media files, not scripts.

What should you avoid when protecting your website?

A quick Google search will give you plenty of tips and strategies to secure your site. Several security plugins will also provide several options to protect your site from password crackers. Protecting your website is something you should be doing, however there are some things you should avoid.

The reasons vary for each of the points I discuss below, but at their core, your measures should provide tangible security benefits, especially if you're asking your users to overcome additional security barriers. For example, if you use both captcha and two-factor authentication, getting to your site becomes difficult, with little added benefit.

You can get an extra sense of security by applying all available options, but in terms of cost-benefit analysis, they don't cut the line.

1. Hide wp login page - You will see this in many forums: change the wp-login page to your site's own URL. The logic is that if hackers can't find the login page, they can't use brute force attacks to gain access to your site. This has several disadvantages:

2. Geoblocking Another commonly recommended security measure is geo-blocking. You may not need or expect legitimate traffic from certain countries and therefore choose to restrict access.
A good firewall can and will protect your site from malicious bots and unwanted traffic. I covered the benefits of firewalls in the previous section.

3. Password protect the wp-admin directory - The wp-admin folder is one of the most important folders on your site. Naturally, it attracts a lot of attention from hackers. Therefore, protecting it with a password may seem like a brilliant move, but counterproductive.

The password protecting your wp-admin directory breaks the AJAX functionality on your WordPress website. AJAX is an encoding technique that downloads parts of your website from the server without changing the currently displayed page.

If that sounds like gibberish, what it essentially means is that it makes your site dynamic without constantly reloading users every time something changes.

Think about scrolling through your social media feed. New stories or tweets load while you're still reading the ones already on your screen, and you can refresh your news feed whenever you want to load new content.

4. Hide WordPress Version - The logic behind hiding the version of your WordPress site is due to security updates. If your website is not running the latest version of WordPress, a hacker could exploit a vulnerability that exists in an older version. However, hiding your version of WordPress is of no use. There are several ways to determine the WordPress version of a website: checking the site's external code, checking the RSS feed, etc. All of them are legal, by the way.

The way to deal with WordPress vulnerabilities in older versions is to update your version to the latest. Many website administrators fear that updating a live site can break it. So it's best to do it on a test site first.

What to do if your site is hacked?

If your site has recently been hacked, it is even more important for you to be extremely attentive to the security of your site. If not done correctly, it can lead to repeated site hacks, and the whole situation turns into a complete nightmare.

All In One WP Security & Firewall - WordPress site security

In short: The easiest way to protect your site is to install a site security plugin such as: All In One WP Security & Firewall is a comprehensive, easy to use, stable and well maintained WordPress security plugin.
