Website security audit best practices - 5 steps
Website security is an essential aspect that every website owner must prioritize. Websites that are not properly secured can be vulnerable to various cyber attacks, such as hacking, data breaches, and malware infections. These can have devastating consequences for the website owner, including financial loss, damage to reputation, and loss of customer trust.
Therefore, website security should be taken seriously, and website owners must perform regular website security audits to identify and address any potential security issues. In this article, I will discuss the steps involved in conducting a website security audit.
What is website security audit?
A website security audit is a process to evaluate a website's security measures, identifying vulnerabilities and weaknesses. It involves reviewing server configurations and analyzing code for common vulnerabilities, helping website owners address potential risks.
Steps to website security audit
A website security audit involves a series of steps and processes that aim to identify vulnerabilities and potential security risks, as well as to evaluate the effectiveness of existing security measures. In this section, we will discuss the key steps involved in a website security audit.
#1 Run a security scan for vulnerabilities
The first step in a website security audit is to perform a comprehensive scan of the website to identify potential vulnerabilities and security risks. There are several tools available that can help in this process, including vulnerability scanners and penetration testing tools. These tools can identify common vulnerabilities such as outdated software, weak passwords, and SQL injection attacks, among others.
Once vulnerabilities are identified, the next step is to prioritize them based on their severity, and take appropriate measures to address them. This may involve patching vulnerabilities, updating software, or implementing additional security measures.
#2 Review site settings
The second step in a website security audit is to review site settings to ensure that they are configured securely. This involves reviewing settings such as file permissions, user roles and permissions, SSL certificates, and others. Improperly configured site settings can result in security vulnerabilities that can be exploited by hackers and other malicious actors.
Some key site settings that need to be reviewed include:
File permissions: This involves reviewing the permissions of files and directories to ensure that they are set up correctly. Improperly set file permissions can result in unauthorized access to sensitive data.
User roles and permissions: This involves reviewing the roles and permissions assigned to users to ensure that they are appropriate and secure.
SSL certificates: This involves ensuring that SSL certificates are properly configured, up-to-date and valid, and that they are used consistently across the site.
Backup settings: This involves reviewing the site's backup settings to ensure that backups are being created regularly and stored securely.
#3 Check for renewals
The third step in a website security audit is to check for renewals of important security elements. This involves checking the status of important elements such as SSL certificates, domain names, hosting accounts, and others. It is important to ensure that these elements are up-to-date and that they have not expired, as an expired SSL certificate, for example, can result in a security breach.
Some key elements that need to be checked for renewals include:
SSL certificates: SSL certificates need to be renewed periodically to ensure that they remain valid and secure.
Domain names: Domain names need to be renewed periodically to ensure that they remain under the control of the website owner and are not hijacked by malicious actors.
Hosting accounts: Hosting accounts need to be renewed periodically to ensure that the site remains accessible and secure.
#4 Analyze website traffic
The fourth step in a website security audit is to analyze website traffic to identify potential security risks. This involves reviewing website logs and analytics to identify patterns of suspicious activity such as multiple login attempts, brute force attacks, or other unusual activity.
Some key metrics to analyze when reviewing website traffic include:
Login attempts: Reviewing login attempts can help identify potential brute force attacks and other unauthorized access attempts.
Traffic sources: Reviewing traffic sources can help identify potential sources of spam or other malicious activity.
User behavior: Analyzing user behavior can help identify potential threats such as phishing attempts, malware downloads, and other malicious activity.
#5 Test manually
The final step in a website security audit is to manually test the website. While automated tools are helpful, they cannot catch everything. Manual testing allows you to identify vulnerabilities that may have been missed by the scans or that require a more nuanced approach. Here are some tips for manual testing:
Perform a comprehensive review of the website code, especially for any custom code. This can be time-consuming, but it is essential for identifying vulnerabilities.
Test for common vulnerabilities such as SQL injection, cross-site scripting (XSS), and cross-site request forgery (CSRF). These vulnerabilities can be exploited to gain access to sensitive data or take control of the website.
Test the website forms to ensure that they are secure and that data is being properly validated and sanitized.
Test user authentication and authorization mechanisms to ensure that they are secure and that only authorized users can access sensitive data or functionality.
Test the website for SSL/TLS configuration issues, including certificate expiration, weak ciphers, and improper certificate chaining.
Test the website for vulnerabilities related to third-party integrations, such as payment gateways or social media logins.
Check for file upload vulnerabilities that can be exploited to upload malicious files to the server.
Test for vulnerabilities related to session management, such as session fixation or session hijacking.
Test the website for denial of service (DoS) vulnerabilities that can be exploited to overload the server and take the website offline.
Finally, consider performing a penetration test, which is a simulated attack on the website to identify vulnerabilities that could be exploited by a real attacker.
By following these steps, you can identify and mitigate vulnerabilities in your website before they can be exploited by attackers. While website security audits can be time-consuming and require a significant amount of expertise, they are essential for ensuring that your website is secure and protecting both your business and your users.
Implement Security Measures
After analyzing the website, it's essential to implement the necessary security measures. This step will prevent potential threats and help secure the website.
There are different security measures to implement, including:
Install security plugins or software: There are various security plugins and software available to protect the website from malware, viruses, and hacking attempts. These tools offer features such as firewall protection, malware scanning, and spam filtering. Some popular security plugins include Wordfence, iThemes Security, and Sucuri.
Use HTTPS: HTTPS is a secure version of HTTP that encrypts the data exchanged between the website and the user's browser. It prevents hackers from intercepting and stealing sensitive information such as passwords and credit card details. HTTPS is now a ranking factor in Google's search algorithm, which means that having a secure website can improve its search engine visibility.
Keep software up-to-date: Keeping the website's software, including its CMS, plugins, and themes, up-to-date is crucial in preventing security breaches. Developers regularly release updates that address security vulnerabilities and fix bugs that could be exploited by hackers. Failing to update software promptly increases the risk of attacks.
Use strong passwords: Weak passwords are a common entry point for hackers. Using strong and unique passwords for every account associated with the website can significantly reduce the risk of unauthorized access. It's recommended to use a combination of uppercase and lowercase letters, numbers, and symbols.
Limit login attempts: Limiting the number of login attempts can prevent brute-force attacks, in which hackers try to guess the password by submitting multiple login attempts. Implementing login attempt limits and CAPTCHA verification can deter hackers and protect the website.
Backup regularly: Backing up the website regularly is essential to protect against data loss due to security breaches or server failures. Having a backup also allows for a quick restore in case of an attack. It's recommended to store backups on external servers or cloud storage to ensure they are secure.
Use two-factor authentication: Two-factor authentication (2FA) adds an extra layer of security by requiring a second method of authentication, such as a one-time code sent to a mobile device. It prevents unauthorized access even if the password is compromised.
Remove unused software: Keeping unused software on the website can pose a security risk as it can contain vulnerabilities that hackers can exploit. It's essential to regularly remove any unused software and plugins to reduce the attack surface and minimize the risk of attacks.
Educate users: Educating users about safe browsing practices can go a long way in preventing security breaches. It's essential to provide guidelines on creating strong passwords, avoiding suspicious links, and recognizing phishing attempts. Regularly reminding users to update their passwords and use 2FA can also help improve the website's security.
By implementing these security measures, website owners can significantly reduce the risk of security breaches and protect their website and users' sensitive information.
