Complete WordPress Site Protection

Security Ninja has protected websites since 2011!

I thought WordPress was a secure platform?

You might be thinking why would you need more protection, and what difference could a plugin do to your website.

WordPress Security does not have to be hard - protect your websiteWordPress itself is a secure platform, but no system is never invulnerable and WordPress security plugins are needed to protect you from bad actors trying to access your website. The more popular the CMS, the more people there are who have an interest in getting access to your WordPress site.

Although WordPress is very secure, no system is ever completely impregnable. If you install just the core WordPress system you are pretty secure. The problem is, that is not enough.

The moment you install a theme to make your website look nice, there is always a chance of a bug that can leave a hole into your system. Some WordPress themes are better built than others and it is not possible to see the quality of the theme just from looking at the visual style.

You need to go through the actual code of a theme to fully evaluate it, and let's face it - how many people do that?

You are also bound to install several plugins, simply to bring the features you need to the website. Each theme has different requirements so even if you keep the amount low, most websites will have 20, 30 or even more active plugins at the same time.

Each of these plugins might have a security hole that has not been seen yet or use a 3rd party library that has a bug that can be exploited.

The sad fact is - No matter how conscious you are about your security, no matter how good your password management is and what else you do, your site will never be fully secure.

What you do is try your best to protect yourself and your website. You do this by installing a security plugin, and we are super biased here, and we think you should use Security Ninja to protect your WordPress website 🙂

web-securityEven the smallest website needs protection, you are not facing attacks by cybercriminals that look for new businesses in your area or notice you because your website is popular and you make a lot of sales. Of course, the bigger the website, the more appeal to break in.

However, you are not facing individual people with a grudge against you, your website will be under attack from automated systems that scans millions of websites for vulnerabilities or just flat out start an attack - all without a human being pointing a finger at your site or clicking a mouse.

You might think there is no reason to attack small websites, but that is a dangerous way of thinking - every website can be used for malicious purposes, even small sites.

Protect your website from attacks!

Our plugin scans for over 50 different known issues that can help block malicious activity. Fixing each of these can help you

Core scanner - Once a virus or malware has entered your site, many will try to infect the WordPress core files.

Scanning the WordPress Core files is a part of Security Ninja Pro, that will check and compare each of the files in your website versus the files from the official core files.

We find all the files that are on your system, makes sure there are only the files you should have in the folders that WordPress use, and we warn you if there are any files that should not be there. The other files that we know should be there are checked one by one and compared with the version we know from is the original.

Protect your WordPress blogEven a simple linebreak will stand out in each file and you will get the choice to flat out delete the file (be careful) or restore it with the official version from - Remember, you should never touch the WordPress core files, nor should any developer ever edit those files. If they do, find a different developer. If they are so lax in their programming to modify the WordPress core files, you can be sure they are also very lax in their security knowledge and experience.

Keeping your website secure can be difficult and time-consuming. We think WordPress security can be easy, and our plugin has many security features that will protect your site.

With audit logging in the event logger (Pro only feature) you can keep track of what is going on, and which user did what and when. By keeping a log of what is going on you can also identify IP addresses that should be blocked if there are many attempts to log in or otherwise compromise your site.

Plugins and themes are checked for malicious files, Security Ninja Pro comes with a powerful heuristic scanner that can detect patterns and code samples in your plugins and theme and alert you to any suspicious files.

As a website owner, you also need to keep your employees to have strong passwords and also follow strict login security yourself. Two-factor authentication is always a good idea to improve your website.
It might feel frustrating spending a couple more seconds logging in, but compared to the many many hours and days you will spend if you get hacked, it is worth it.

The pro version also protects you with a cloud firewall that blocks millions of known bad IP addresses from even accessing your website.

 Protecting your business - WordPress website security

Protecting your website from cyber criminals is crucial for a small or medium business owner. In this beginner's guide, we'll take you through the steps to securing your WordPress website and the best practices for maintaining its security.

Why WordPress security is important for small/medium businesses

WordPress security is crucial for small and medium businesses, as even the smallest website can face attacks from automated systems that scan millions of websites for vulnerabilities.

Installing a security plugin like our WP Security Ninja can help block malicious activity by scanning for known issues and checking the WordPress core files. Additionally, plugins and themes are checked for malicious files using a heuristic scanner to detect patterns and code samples in your plugins and theme, alerting you to any suspicious files or identified viruses and malware.

Regular updates, backups, strong passwords, and two-factor authentication are also essential to safeguarding user data on your website.

Potential risks and consequences of a security breach

A security breach can have severe consequences for your business, including loss of revenue and credibility. Customers impacted by the breach may take legal action against you, further damaging your brand reputation.

It is, therefore, crucial to protect your website with firewalls, blocklists, and regularly updated SSL certificates to prevent unauthorised access to sensitive data stored in your database or application.

Don't let a single vulnerability bring down everything you have built - secure WordPress now before it's too late!

Breaches take time away from your business

A security breach can have significant consequences for your business goals. It can result in increased downtime while resolving the issue, distracting you from core business objectives and incurring costs associated with investigating and addressing the breach.

Installing a security plugin such as our Security Ninja to block malicious activity is vital to your website security.

Automated systems scan millions of websites for vulnerabilities without human intervention, so even small sites need protection against potential attacks that could affect their business goals.

Even small websites are valuable targets for hackers

You might think a small website is not interesting for hackers, but you would be wrong. Small websites are great for malicious purposes, such as spreading malware or launching attacks on other websites.

Small websites are often the most unattended and least monitored websites, allowing hackers to do more damage over time. Even if your website does not contain sensitive data, the website is still very much usable for hackers.

It is essential to take website security seriously, as the potential risks and consequences of a security breach can be devastating for your business. By installing a security plugin and following best practices for website security, you can protect your website and your customer's data, ensuring your business's credibility and reputation.

Common security threats to WordPress websites

One of the most common security threats to WordPress websites is malware infections through vulnerable plugins or themes. Hackers can exploit weaknesses in these add-ons to gain access and infect your website with malicious software that steals data or damages your system.

Another danger comes from "brute force" attacks on login credentials, where hackers try multiple username and password combinations until they find the correct one. Moreover, unsecured forms or comment sections present a risk for Cross-Site Scripting (XSS) attacks that inject harmful code into your site, jeopardising user privacy and damaging your reputation as a trustworthy business owner.

Protecting against these threats requires regular updates, backups and installing reliable security measures.

The importance of regular updates and backups

Regular updates and backups are crucial in maintaining the security of your WordPress website. Outdated software versions leave your application vulnerable to known vulnerabilities, which attackers can exploit.

Regular updates ensure that you have the latest patches to protect against these threats. Backups also play an important role in ensuring protection against data loss in case of a security breach or system failure caused by outdated software components. By updating frequently and backing up regularly, you avoid website downtime due to system failures caused by outdated software components, preventing potential losses for your business.

Privacy issues - safeguarding user data

Protecting user data is crucial in today's digital landscape, as cyber threats are becoming increasingly sophisticated. Unencrypted communication channels used by visitors open up the risk of "Man-in-the-middle" attacks where hackers can intercept and steal sensitive information. Public Wi-Fi networks also pose a risk of "Passive eavesdropping," where attackers can monitor network traffic and gain access to personal data.

Another common threat is through phishing scams posing as legitimate requests for sensitive information, such as login credentials or personal details. To safeguard against these risks, you should implement security measures on top of a security plugin.

Types of attack your website is facing

Your website is under attack when you buy the domain and install WordPress. Many automated scripts keep an eye on new websites and immediately start scanning them for potential vulnerabilities.

Bruteforce attacks

One common type of attack is a brute-force attack, where hackers use automated software to guess your login credentials by trying different combinations of usernames and passwords. This can be prevented by using strong, unique passwords and limiting login attempts.

Another way to prevent brute-force attacks is by implementing two-factor authentication, which requires an additional step for users to verify their identity before gaining access to the website.

This can be done through SMS codes, email verification, or third-party authentication apps.

Malware for WordPress

Malware is also a major concern, as it can be injected into your website through vulnerabilities in themes and plugins. This can result in your website being used to spread malware to your visitors and getting your website blacklisted by search engines. To protect against malware, website owners should regularly scan their websites using security plugins like our WP Security Ninja, which can detect malicious code.

It's also important to keep all themes and plugins up to date to patch any known vulnerabilities that hackers could exploit.

Malware for WordPress is a growing concern for website owners. Malicious code can be injected into your website through vulnerabilities in themes and plugins, which can result in your website being used to spread malware to your visitors or even being blacklisted by search engines. Malware can also steal sensitive information such as login credentials, credit card details, and personal information.

Malware attacks are on the increase, and with the continued success of WordPress, the platform is a significant and exciting target for attackers to find security holes to exploit.

Even secure websites are vulnerable to new and unknown bugs, so it's essential to keep all themes and plugins up to date to patch any known vulnerabilities that hackers could exploit.

Attacks via known plugin vulnerabilities

There are regular reports in the security community about new known vulnerabilities in WordPress plugins and themes. Some plugins have just a few users, but many well-known WordPress plugins with hundreds of thousands or even millions of users have been known to have added vulnerabilities by mistake.

We have a vulnerability scanner included in our plugin for both free and premium users. A list of known security exploits is downloaded via our API and then compared locally on your server. If a vulnerability is found, you will be warned in the admin, and you can also set up the plugin to send you an email. The automated check for vulnerabilities runs every day.

SQL Injection Attacks

SQL Injection attacks are another form of attack that can give hackers access to your database, allowing them to steal sensitive information. This can be prevented by using secure coding practices and using a security plugin that detects and blocks SQL Injection attempts via a WAF firewall.

If you stay with large, established plugins and services, you are less likely to encounter problems from insecure coding practices. Large, established plugins are also subject to coding mistakes and missing security checks, so you should always use additional protection with a firewall to block suspicious requests.

Steps to secure your WordPress website

Protect your WordPress website by following these simple steps. Choose a secure hosting provider that uses the latest technology to protect your site from cyber attacks. Use strong passwords and enable two-factor authentication for an added layer of security. Install and configure WP Security Ninja to scan for vulnerabilities, limit user access and permissions, and regularly scan for malware. Stay vigilant by keeping an eye out for email warnings about potential threats to your website's security. By taking these precautions, you can ensure that your WordPress website stays safe from malicious hackers looking to exploit vulnerabilities in your system.

Choose a secure hosting provider

Choosing a secure hosting provider is critical for protecting your WordPress website. Research potential hosts and read reviews to ensure they have a solid reputation for security. Look for hosts that offer automatic updates and backups, so you can rest easy knowing your site is always up-to-date and recoverable in case of an attack or data loss. Finally, consider hosts with built-in security measures like firewalls to add an extra layer of protection against potential threats. By taking these precautions when selecting your hosting provider, you can significantly reduce the risk of cyber-attacks on your business's website.

Use strong passwords and two-factor authentication

Protect your WordPress website by using strong passwords and two-factor authentication. Avoid using easily guessable passwords or personal information as they are easy targets for hackers. Instead, use a password manager to generate and store complex passwords that include a mix of uppercase letters, lowercase letters, numbers, and symbols.

Enable two-factor authentication for an extra layer of security. This requires users to provide additional verification beyond their password when logging in, such as a code sent to their phone or email. It might feel frustrating spending a couple more seconds on logging in with 2FA enabled but it's worth the peace of mind knowing that you've taken an extra step towards securing your website.

  • Use strong and complex passwords
  • Avoid easily guessable phrases or personal information
  • Utilize a password manager program
  • Enable two-factor authentication

Install and configure WP Security Ninja

WP Security Ninja is a powerful plugin offering various features to help secure your WordPress website. With regular scans, you can check for vulnerabilities and malware on your site.

The firewall also blocks malicious traffic from known bad IPs and known spammers, ensuring better protection against potential attacks. These tools help make sure your business's online presence is secure and protected from threats.

Limit user access and permissions

When it comes to WordPress website security, limiting user access and permissions is a crucial step in protecting your business. By only giving necessary access based on each individual's role within the organization, regularly auditing accounts, and enforcing strong password policies across all users, you can significantly reduce the risk of a breach. Here are some tips to keep in mind:

  • Assign roles and restrict access accordingly
  • Regularly review user accounts for any that are no longer necessary and remove them promptly
  • Enforce complex passwords containing numbers, letters (both uppercase & lowercase), symbols, etc.

By following these guidelines and ensuring that your employees understand the importance of good security practices for your website's protection as well as their own personal information safety; you'll be able to maintain control over who has access while reducing the likelihood of an unauthorized person gaining entry.

Regularly scan for vulnerabilities and malware

Regularly scanning for vulnerabilities and malware is an essential step in protecting your WordPress website. By scheduling routine checks through specialized tools, you can identify any potential threats and take action to prevent them from causing harm. Using reputable antivirus software also adds an extra layer of protection against viruses and malware.

To ensure the safety of your website, consider implementing frequent backup creation as part of your security strategy. This allows you to restore your site to a previous version if it becomes compromised or experiences any issues. Taking these proactive measures can save you time, money, and reputation damage in the long run.

  • Schedule routine scans using specialized tools
  • Implement frequent backups

Keep an eye out for email warnings

Remember email warnings - they could be your first line of defense against cyber attacks. Keep an eye out for suspicious emails, especially those claiming to be from your hosting provider or website administrator. These could be phishing attempts to steal your login credentials or install malware on your site. Please stay vigilant and always verify the sender's identity before clicking links or sharing sensitive information.

Best practices for maintaining WordPress security

Maintaining WordPress security is of utmost importance for small and medium business owners. To ensure your website stays secure, you should have dedicated staff who regularly update and maintain the site's security features. Additionally, it is crucial to stay up to date on the latest security trends and news, train employees on proper security protocols, and perform regular audits to identify potential vulnerabilities.

By taking these steps and utilizing a reliable plugin like our Security Ninja Pro with its heuristic scanner and audit logging feature, you can protect your website from malicious activity while informing yourself about suspicious behaviour or attempted breaches.

Have dedicated staff for maintaining the website

Maintaining a WordPress site is crucial for any small/medium business owner. Assigning a dedicated IT team to handle the maintenance of your site ensures that it's always up-to-date and secure. However, if you need more resources for an in-house team, outsourcing to a third-party vendor or hiring an external agency can also be beneficial options. You can even outsource specific tasks like security management to ensure your website remains protected without putting extra strain on your resources.

Let's face it - there are plenty of other things to take care of when running a business, and security newsletters might not be the most exciting thing for you.

If you are not able to do this as a business owner, you should ensure you have inside or outside advice - make sure to install security software at least and have an automated backup schedule set up - that could be very helpful one day if you have issues with the website.

Train employees and staff on security protocols

Conduct regular training sessions for employees on best practices in online safety to ensure that every member of your team is aware of the potential threats and how they can help keep the company safe. It’s also essential to provide all new hires with adequate cybersecurity training when they join the company so that they are familiar with security protocols from day one.

Encourage employees to report any suspicious activities or incidents immediately, as this can help prevent potential attacks before they cause any damage.

Here are a few topics you could include in your employee cybersecurity training:

  • Common types of cyberattacks (phishing, malware etc.)
  • Best practices for creating strong passwords
  • How to avoid clicking on suspicious links or downloading unknown attachments
  • The importance of keeping software and antivirus programs up-to-date
  • Safe browsing habits while using public Wi-Fi or personal devices

Perform regular security audits and assessments

Ensuring the security of your WordPress website is crucial to protect your business from cyber-attacks. Schedule periodic vulnerability scans, and conduct penetration testing once every quarter to identify any potential threats.

Check the server logs for breaches

It's also essential to review access logs frequently, particularly after significant changes are made, to monitor user activity and detect any unauthorized access attempts. Regular security audits and assessments can protect your website against malicious activities that could jeopardise your business's reputation and finances.

In the digital age, protecting your business website is essential. WordPress is a secure platform, but as with any system, there are vulnerabilities that can be exploited by cybercriminals. Installing a security plugin such as Security Ninja can protect your website from various malicious activities.

Even small websites are at risk of being targeted, and it's crucial to protect your website from cyber-attacks. The Security Ninja plugin scans for over 50 different known issues that can help block malicious activity. Our premium version includes a firewall, malware scanner as well as a core scanner that compares your website's files to the official core files to identify modified or unnecessary files.

Investing in website security may seem like a daunting task, but it's essential to protect your business from cyber-attacks. With the right measures, you can secure your website and protect your business's reputation and finances.
