What is a Website Security Audit?

A website security audit is a comprehensive assessment of your site, designed to identify any vulnerabilities, weaknesses, and potential threats in its integrity, systems, network, and data processing. This systematic examination evaluates various aspects of the website, including your web hosting, software infrastructure, third-party apps like plugins, databases, user access and roles, and the website’s code. The goal of performing these checks is to find any security gaps that could be exploited by hackers and malicious software.

It involves using tools and methods to find weak points, letting you address and fix them, and improving your defenses before they can cause data breaches and damage to your online business.

Why Perform a Security Audit?

As we’ve already covered, when it comes to secure web hosting, site security audits help you spot vulnerabilities and weaknesses in your website that could be exploited and used as potential entry points for cybercriminals. You can reduce the risk of a successful attack by actively addressing them. It also lets you stay ahead and continuously upgrade your defenses, making it much harder for your systems to be hacked and harmed as new threats emerge, and maintain your overall security posture.

Protecting User Trust

A security audit can help build and maintain user trust. Your users expect their personal and financial data to be safe when visiting and interacting with your website. If your site gets hacked you run the risk of their data being stolen, damaging your reputation, and lowering your SEO (Search Engine Optimization) score. This is because search engines prioritize safe sites in results pages, and users are less likely to engage with your pages if they have been compromised.

By regularly assessing and improving your security features, you can show users that you take their privacy seriously, enhancing your reputation and showing search engines your site is trustworthy.

The Impact of Security Breaches

Security breaches can have devastating consequences for your business. The financial impact alone can include costs related to incident response, system and user data recovery, legal fees, and potential fines.

Beyond the immediate losses, security breaches can lead to long-term reputation damage and lost customer trust, further affecting your bottom line. By conducting regular audits, you minimize the risk and impact of security issues, avoiding potentially catastrophic financial and reputational harm.

Legal and Compliance Requirements

Many industries and types of websites are subject to strict data privacy laws and compliance requirements, such as GDPR (General Data Protection Regulation) or PCI DSS (Payment Card Industry Data Security Standard). Performing regular audits is often mandated by these regulations and helps ensure that your security policies and data handling methods meet the required industry standards.

Compliance also helps you avoid potential fines and legal issues caused by not adhering to the above data protection regulations.

Common Security Risks to Watch Out For

Understanding and identifying common security vulnerabilities is essential for maintaining your website’s defenses. Here are some of the most common vulnerabilities and attack vectors to watch out for:

SQL Injection

SQL Injection is a code injection technique that exploits vulnerabilities in how websites interact with databases. Attackers can manipulate or retrieve data, bypass authentication, and perform admin tasks instead of website owners.

You can prevent this by granting user accounts the minimum permissions needed. This limits the potential damage if an account is compromised. Check user input for unexpected or malicious characters, this helps prevent attackers from manipulating SQL statements.

Instead of directly inserting user input into SQL statements, use placeholders filled in by the database system. This prevents attackers from injecting malicious code.

Cross-Site Scripting (XSS)

XSS attacks involve injecting malicious scripts into web pages viewed by other users. These attacks can lead to theft of sensitive data, session hijacking, and malware infections.

To help avoid these attacks, keep your software, themes, and plugins updated and use Web Application Firewall (WAF) to help block harmful requests.

Validate and sanitize user input to remove harmful characters before they are processed and implement client and server-side form validation to check for invalid or malicious data.

Cross-Site Request Forgery (CSRF)

CSRF attacks trick users into performing unwanted actions on a website where they’re authenticated. This can result in unauthorized fund transfers, changed passwords, and data theft.

To prevent them, you can implement anti-CSRF tokens which generate unique, unpredictable tokens for each request stopping attackers from forging requests. Check the HTTP Origin and Referrer headers to ensure that requests come from a trusted source.

Preparing for a Security Audit

Proper preparation is the first part of conducting a security audit. By using a proactive approach, you can ensure that your audit is comprehensive and gives you the correct outcome at the end.

Website Security Audit Checklist

Before starting, you need to have an inventory of all the components that make up your website to make sure nothing gets missed during the process. This list should include:

• Settings: Your website and hosting server configurations and setup.
• Software: A complete list of all software used, including the core site software, plugins, themes, and custom extensions.
• Third-Party Integrations: Any external services or features that your website uses.
• Data Storage: Where and how your users’ sensitive data, including personal and financial information, is stored, and processed.
• User Access: A list of all access points, such as admin dashboards, login areas, and assigned user accounts.
• Network: Details of your network’s setup, including firewalls, load balancers, and content delivery networks.

Objectives and Scope

Next, you need to establish what you want to achieve with the audit. For example, meeting new compliance requirements, addressing specific security issues, or doing a general assessment.

Decide which parts of your website and infrastructure will be included, this could be focusing just on the front-end, the back-end systems, or both. Make sure you prioritize the most important elements, and which parts of your site require the most attention as part of your risk assessment.

7 Steps to Conduct a Website Security Audit

Now that you have a plan in place, here are the steps to conduct your website security audit and make sure your site is checked for potential vulnerabilities and security issues.

Step 1: Malware Check

Begin with a thorough scan of your website. Use malware detection tools and anti-virus software to identify and remove any malicious code, backdoors, or hidden infections that could compromise your site’s security. This first step is vital as malware can often go undetected and cause severe damage if left unchecked.

Step 2: Vulnerability Assessment

Conduct a broad assessment of your website’s potential vulnerabilities to cyber threats. This involves examining your site’s structure, components, and configurations to identify weak points that could be exploited. Look for common gaps like outdated software, misconfigured settings, or weak passwords.

Step 3: Conduct a Vulnerability Scan

Use automated vulnerability scanning tools to perform a deep dive into your website’s security posture. These tools can quickly spot a wide range of possible kinds of security issues. Automated scans can cover large portions of your website faster than doing it manually and flag areas that require further investigation with a detailed report.

Step 4: Perform Penetration Testing

Engage in penetration testing, or “ethical hacking,” to simulate real-world attacks on your website. This step involves attempting to exploit the vulnerabilities identified in previous steps to assess the actual risk they pose. Penetration testing can show you how easily an attacker might be able to gain access to and manipulate your systems.

Step 5: Check for Software Updates and Patches

Review all software components of your website, including the content management system, plugins, themes, and any custom applications. Ensure that all elements are up to date with the latest security patches. Outdated software is a common entry point for attackers, so this step is crucial for maintaining a secure environment.

Step 6: Review User Access Controls

Examine your website’s user access controls and permissions. Ensure that user roles are properly defined with only the necessary level of access to perform their tasks. Look for any unused accounts, especially those with high-level permissions, and remove or disable them. Implement strong password policies and consider adding multi-factor authentication for sensitive areas of your site.

Step 7: Implement Security Improvements and Fixes

Based on the findings from the previous steps, develop and implement a plan to address the identified vulnerabilities and security weaknesses. This may involve applying software patches, reconfiguring settings, getting a new SSL certificate, updating access controls, or even completely redesigning certain parts of your website to fix security flaws. Always prioritize your fixes based on the severity of the vulnerabilities and their potential impact on your website’s security.
