How to Perform a Basic Security Audit on Your Website

Is your website secure or an easy target for hackers?

Hackers consistently seek out weaknesses in websites. Even the smallest security flaw can lead to breaches that result in stolen information and financial loss. If your website isn't secured, it may only be a matter of time before attackers infiltrate it.

A website security audit helps identify vulnerabilities and resolve them before a hacker takes advantage. It ensures the website adheres to best practices concerning security, including the standards of ISO 27001, OWASP, and compliance with the General Data Protection Regulation. 

By using tools like a website vulnerability scanner, you can quickly detect and fix potential security gaps. Regular security audits keep your site’s information secure, protect your users, and build trust by showing visitors that their data is safe.

What is a Security Audit?

A security audit studies your business defense systems, looking for potential weaknesses that cybercriminals can exploit. This audit inspects all areas, including data protection guidelines, system protection elements, building properties, and staff tasks.

The goal? Find vulnerabilities before cybercriminals do. During a security audit your defenses will be tested to find vulnerabilities while presenting specific actions for a stronger security stance. Your business remains secure and aware of new dangers when you conduct audits regularly.

Why Do Companies Need Security Audits?

Security audits are important because organizations require them to gain an understanding of the extent of their risks, compliance with regulatory standards, and safeguarding their information and image. So, here are the most important points regarding security audits:

1. Identify & Fix Vulnerabilities

• Security audits help to find weaknesses in websites, networks, and applications.
• Preventing data breaches, malware infections and unauthorized access before attackers can exploit them is the reason for them.

2. Protective Sensitive Data

• The business handles customers’ data, financial records, intellectual property, or anything else.
• Security audits verify the security of storage, encryption, and access to prevent leaks.

3. Prevent Financial & Legal Consequences

• Fines, lawsuits, and loss of business can all be a result of a security breach.
• They can face heavy penalties for non-compliance with regulations such as GDPR, HIPAA, PCI-DSS, etc.

4. Maintain Customer Trust & Brand Reputation

• A hacked website or data breach is bad enough to ruin a company’s reputation.
• Businesses should secure their customer’s personal information and keep private information private.

How to do a website security audit?

A website security audit evaluates weaknesses, assesses risks, and implements security protocols in place for defending against possible threats. This is a step-by-step guide: 

Step 1: Identify Website Assets

It's very important, before starting with a security audit, to understand what you're protecting. You should start with a comprehensive listing of all assets on your website. This is:

• Domain and Subdomains: Identify all forms of variants of your website's domain name to cover all the possible links to that domain.
• Provider of Web Hosting: This gives you an idea of where the hosting for the website is and what physical security is in place.
• SSL Certificates: Verify that the SSL/TLS certificates you are using are current and when the next renewal date is.
• Connections: Identify which databases are relevant to your website and ensure they are secure.
• APIs and Integrations: List down all third-party services integrated and interacting with the website.
• User Accounts and Permissions: Settings of all the users that have access to your website.

This is a foundation for determining what content on your site needs to be encrypted and which assets are most important.

Step 2: Check SSL/TLS Encryption

A secure website uses HTTPS to ensure information transmitted between the client and server is safe. Be certain your SSL/TLS certificates are configured correctly and that the latest ones are utilized by using SSL Labs' SSL Test to make a comparison of the level of encryption over possible vulnerabilities.

Check the compliance of your TLS settings with current security standards and disable all insecure ciphers. A secure SSL/TLS helps to prevent man-in-the-middle attacks that compromise your website and keep the data entered by the visitors safe.

Step 3: Scan for Vulnerabilities

Utilize easy ways to check website vulnerabilities for known exploits. These will define areas in your code that are prone to attacks, corrupt configurations, and outdated features that make your site vulnerable. Some tools to consider:

• OWASP ZAP: A widely known tool for testing the security of web applications and helps detect possible vulnerabilities.
• Nikto: An HTTP scanner capable of detecting vulnerabilities of outdated software and misconfigured systems.
• Acunetix: A functional and powerful scanner used for such serious vulnerabilities as SQL injection and cross-site scripting.
• SSL Labs: The best site to assess SSL/TLS configurations.

It prevents hackers from taking advantage of vulnerable points in your security system by scanning for them routinely.

Step 4: Review User Access and Permissions

One of the most common ways attackers gain access to systems is through weak or unauthorized user accounts. To prevent this:

• Audit User Roles: Limit the scope of users for only working with the sections that you know that they should gain access to. Limit admin accounts.
• Expire Old Admins: Disable long-unused or never-used accounts. This will give you fewer avenues for threats
• Enforce Strong Password: Complexity All passwords must have a minimum set strength and satisfy the required security standard.
• Activate Multi-Factor Authentication (MFA): This means the user or an admin will be required to put more elements, beyond a password, to fully log in.

Step 5: Keep Up to Date on Outdated Software

The usage of outdated software creates a major security risk for systems. Most attackers go after attacking existing vulnerabilities that are found in outdated CMS platforms, server software, and installed plugins. To ensure your website is kept safe,

• The CMS needs to run the most recent version using either WordPress, Joomla, or Drupal.
• Update both the plugins and the themes regularly. Hackers generally attack systems using old, outdated plugins.
• Upgrade every component on your server from a web server up to databases for the protection of the system.

Auto-updates will make it more efficient; however, all updates should first be tested on the staging environment before being used on the production level.

Step 6: Malware and Security Scan

Malware is a security threat that causes significant problems on your website through file destruction, data theft, and malicious site redirection. How to prevent this:

• Sucuri SiteCheck: This scans your site for malware infections and blacklisting.
• Google Safe Browsing: Check here if Google flagged your site as dangerous.
• Wordfence: This is a WordPress plugin that scans for malware and offers real-time firewall protection.

Step 7: Validate Security Headers

Security headers are extra measures, such as cross-site scripting as well as clickjacking. Check that the settings of the following header vary the following:

• Content Security Policy (CSP): Prevents XSS attacks by specifying resources that are allowed to be loaded on the site.
• HTTP Strict Transport Security (HSTS): This means forcing the secure connection so that all the transmission is safe.
• X-Frame Options X-Frame will guard against clickjacking.
• X-XSS Protection: Blocks some types of XSS attacks.

Use the Security Headers tool to check for missing or misconfigured security headers.

Step 8: Perform a Backup and Recovery Test

These are crucial in case there is a break in or loss of data in the organization. Ensure you:

• Back-up copies: It is important to back up the web contents, such as files and databases, daily or weekly at most.
• Backup Management: It is recommended to take the backups every day and keep them in another secure place.
• Disaster: From time to time, make sure you have a backup that can be used in the event of misfortune.

Step 9: Analyze Website Logs

These logs are quite helpful in predicting possible security threats in the network. Review:

• Server Logs: Monitor information service activity, signs of possible errors, and other suspicious activities.
• Application Logs: Keep a check on Login, Invalid credentials, and other activities that look like a potential threat.
• Security Plugin Logs: This way, use the security tools to analyze the potentially dangerous threats.

Tools like Splunk or Graylog can automate log analysis and alert you to anomalies.

Step 10: Document Findings and Implement Fixes

After doing your audit, document the outcomes and prioritize the motions in light of risk severity. Key actions include:

• Address High-Risk Issues: Eliminate high-risk issues as soon as possible.
• Security Improvement Strategy: Work through medium and low-risk issues.
• Implement Security Policies: Set up standard operating procedures to monitor security routines.
