How to protect your website against attacks

Why is website security important to every user?

Appropriate website security not only protects against potential attacks by cybercriminals, but also builds user trust, which is essential for any online activity. A secure website is one that provides protection against various types of attacks, such as phishing, SQL injection, cross-site scripting (XSS), and man-in-the-middle (MitM) attacks.

Implementing solid security measures such as SSL certificates, regular software updates, and strong authentication mechanisms help prevent data breaches that can lead to reputational damage, financial penalties, and even serious legal consequences.

In the context of SEO, website security also affects its visibility in search engines. Google and other search engines prefer sites that offer a secure connection (HTTPS), considering them more reliable. This means that investing in website security not only protects its users, but also improves its positioning, which translates into greater visibility and potentially higher traffic.

Therefore, website security is not only a technical issue, but also an element of building trust and credibility in the eyes of users and search engines.

How do hackers take control of websites?

Common attack methods and how to defend against them

Hackers use a variety of techniques to take control of websites. Understanding these methods and using the appropriate defenses is crucial to ensuring the security of your site. Here are the most common attack strategies and how you can protect yourself against them:

Brute-force attacks: These attacks attempt to guess a website's password by automatically testing many combinations. To avoid them, use strong, complex passwords and enable two-step verification.
SQL Injection: Hackers inject malicious SQL code into forms on a website to manipulate the database. If you want to stay secure, use hardcoded procedures and input validation to prevent code injection. However, if you are not a technical person, just use a CMS system for your website. The developers have most likely thought this through for you.
Cross-site scripting: XSS attacks allow malicious script to be injected into the content of a website, which is then displayed to other users. If you do not want content to be posted on your website without your consent, use Content Security Policy (CSP) and validate and disinfect all input data.
DDoS (Distributed Denial of Service): DDoS involves flooding a website with a huge number of requests in order to block it. If you don't want your website to be inaccessible due to too many bots, use DDoS protection services that can recognize and filter traffic.
Phishing and spoofing: Hackers create fake websites or emails that imitate trusted sources to obtain information. For this reason, educate your users not to click on suspicious links or provide data on unknown sites.
Software vulnerabilities: Outdated software may contain vulnerabilities that hackers can break into. Regularly update all website components, including CMS, plugins and scripts, and you will minimize the risk of attacks due to outdated tools.

Taking these security measures can significantly reduce the risk of an attack on your website. Remember that there is no room for complacency in cybersecurity. Constantly monitor your site, stay up to date with new threats and apply security best practices.

Installing an SSL certificate

What is SSL and how does it affect the security of your website

SSL (Secure Sockets Layer) is a security technology that enables encrypted communication between a web browser and a website server. An SSL certificate ensures that all data sent between the user and the server is encrypted, making it much more difficult for hackers to access sensitive information such as login details, credit card numbers, and personal information. In an environment where phishing and other phishing attacks are commonplace, SSL is the first line of defense against cyber threats.

How SSL affects SEO and website visibility

Google has confirmed that the use of HTTPS (where the "S" stands for a secure connection provided by SSL) is a ranking factor in search results. This means that websites secured with an SSL certificate can be positioned higher than those without such protection. Additionally, web browsers like Chrome mark sites without SSL as "unsecure," which can deter users from visiting your site.

Steps to install an SSL certificate

SSL installation begins with selecting the appropriate certificate provider and purchasing a certificate. Then you need to generate a certificate signing request (CSR) on your server, which is usually done through the hosting admin panel. After submitting the CSR to the certificate provider and verifying domain ownership, you will receive an SSL certificate for installation on the server.

It is important that after installing an SSL certificate, you ensure that all site content is accessible via HTTPS, which includes updating internal links, external resources, and redirects, to avoid mixed content warnings.

The Importance of Regular Backups

Regular backups are a key part of any website's security strategy. This is not only protection against data loss due to hardware failure or hacker attack, but also the basis for quickly restoring the functionality of the website. Regular backups allow you to minimize potential data losses, ensuring the continuity of your online business.

Implementation of the Backup Procedure

Automation: Use backup automation tools. Schedule backups to take place at cyclical intervals, e.g. every day at night, when there is less traffic on the website.
Backup Diversity: Follow the 3-2-1 rule in backups: keep at least three backup copies of your data on two different media, one of which should be stored off-site (outside the main data storage location).
Testing and Validation: Regularly test restoring data from backups to ensure that in the event of a failure, the recovery process will run smoothly.
Backup Security: Protect your backups from unauthorized access by using encryption and strong access and authentication policies.
Monitoring and Logging: Monitor the backup process to detect any errors or irregularities on an ongoing basis. Logging details of backup operations allows for quick response if problems are detected.

Protection against XSS and injection attacks

Preventing Cross-Site Scripting (XSS) attacks

Cross-Site Scripting (XSS) is one of the most common security threats to web applications. It allows attackers to inject malicious JavaScript code into pages viewed by others. To protect your site from XSS attacks, follow these practices:

Input Validation and Sanitation: Validate and sanitize all data coming in from forms, URL queries, and any other data sources. Remove or encode special characters that may be interpreted as code.
Applying a Content Security Policy: CSP allows you to determine where resources on your site can be loaded from, limiting the possibility of executing malicious code.
Using escape functions for dynamic data: When inserting user data into a page, use escape functions on any dynamic data displayed on the page to prevent it from being interpreted as code.

Defense against injection attacks

Injection attacks allow attackers to inject malicious commands into systems via a web application. These include SQL injection, command injection, and more. To prevent these risks, it is recommended:

Using Prepared Statements with bound parameters: This is one of the most effective methods of preventing SQL injection attacks. Prepared queries separate the data from the SQL statement code, preventing an attacker from manipulating the queries.
Input Validation: Validate that your input data meets expected formats. Use lists of allowed values wherever possible and discard any suspicious data.
Privilege Minimization: Ensure that your web application runs with the minimum privileges necessary to perform its tasks. Limit database access to only necessary operations.

Implementation of Web Application Firewalls (WAF)

Implementing web application firewalls (WAFs) is an important element in securing web applications against a variety of threats and attacks. WAF acts as a protective shield between the web application and incoming traffic by analyzing and filtering dangerous requests. Here's how to effectively implement WAF to increase the security of your web application:
