Most of these threats come from web activity that shows website owners are at high risk. The report finds that over a billion unique attacks are being blocked by businesses every month. So, it becomes crucial to implement effective security measures that prevent data breaches, malware infections, and hacking attempts.

With regular security audits, website owners can prevent data breaches and maintain the trust of their users. A thorough website audit assesses every aspect of its security framework, such as CMS platforms, plugins, web servers, and third-party services.

The below step-by-step guide will walk you through the entire website security auditing process. You will also learn about common website security threats, the significance of regular audits, and best practices to protect your site from cyberattacks.

What is a Website Security Audit?

A website security audit systematically examines a website’s security framework to expose vulnerabilities and risks. During an audit, experts aim to discover security weaknesses and fix them before exploitation by cybercriminals. The audit goal is to verify whether existing security measures can defend your website against threats like data breaches, cyberattacks, malware, and hacking. An IBM survey shows that 40% of data breaches involve data stored in public clouds and have incurred the highest average breach cost of $5.17 million.

A website security audit is defined as the process of conducting a detailed evaluation of all potential threats on a website. With regular security audits, website owners can protect their sensitive data while securing users. During a comprehensive website security audit, professionals examine website files and code alongside configurations and access controls and review security policies and procedures. The reviewers evaluate several security layers by checking network security, application security, and industry-standard compliance.

Why Is Website Security Auditing Important?

Website security auditing helps you to reveal and address potential cyber threats, unauthorized access, data breaches, and malware infections. This ensures that your site complies with industry regulations and thus avoids potential fines or legal issues.

Here are a few more reasons why website security audits are so important:

1. Build and Maintain Trust with Users: Secure websites increase the trust level among users. Therefore, users share their personal and financial information with confidence. Regular audits help you keep your website secure and reliable.
2. Improve Site Performance: Website security auditing detects performance issues like loading speed or broken links. Fixing these problems will enhance the user experience and, thus, retain visitors to your site.
3. Avoid Financial Losses: Security breaches are costly and can lead to financial losses and harm your brand’s reputation. Regular auditing can help reduce these risks and protect your business from potential damage.
4. Enhance Incident Response: With regular website audits, you can monitor suspicious activities. Thus, you can respond to security incidents promptly and eliminate threats as soon as they are detected.
5. Jumpstart Search Engine Rankings: Search engines like Google rank secure websites higher. This means that having strong security measures can help you improve your search engine ranking and make it easier for people to discover your website.

Key Objectives of a Website Security Audit

With regular security audits, you can keep your website safe, your users happy, and your business running smoothly.

A website security audit is like a thorough check-up of your website that:

• Finds and fixes website weaknesses.
• Checks if your current security tools are working.
• Adds extra layer of protection if needed.
• Ensures you are maintaining compliance with the industry standards.
• Looks for viruses or hacker activities.

Now let’s understand the key objectives of a website security audit in detail:

1. Identify and fix security vulnerabilities and weaknesses: During a website security audit, experts inspect the website code, plugins, and server settings for weaknesses that hackers could exploit. If they find any weak spots, they can help you fix them to avoid any vulnerabilities and weaknesses.
2. Assessment of the current security status: Assessing current security status involves evaluating how well your website security measures are functioning. This includes checking firewalls, SSL certificates, password policies, and other protective measures to ensure these are effectively guarding your website.
3. Implementing additional security measures where necessary: At times, the security measures you have in place are not sufficient. For instance, if your website does not have two-factor authentication (2FA) or regular backups, the auditors will suggest including these features to further strengthen your website security system.
4. Maintaining industry compliance with security standards and regulations: Different industries regulate differently how a website should protect its user data. For example, if you operate an e-commerce business, you might be subject to rules like GDPR for customer data protection and PCI DSS for handling payment info. A website security audit can help you determine what additional measures you should take to enhance the security of your website.
5. Detecting malware and unauthorized access: Malware is a kind of virus that can harm your website or take your information. It gives unauthorized access to your website without your permission. During an audit, your website is scanned for malware. If there is evidence of a hack, auditors will help you remove it and prevent similar attacks in the future.

Common Website Security Threats & Risks

Website security threats and risks are major concerns for businesses and individuals alike, as hackers continuously develop new methods to exploit vulnerabilities. Around 59% of organizations were hit by ransomware in the last year.

Here are some other common threats that can harm website owners extensively:

1. Malware: Malware finds its way into websites by exploiting existing site code vulnerabilities or using contaminated third-party libraries. Once implemented on a site, this type of software can perform data theft, direct users to dangerous websites, and even gain control of the server function. Additionally, it can transfer harmful content to visitors’ machines.
2. Phishing Scams: Phishing scams attempt to make people hand over their personal information by leading them to fake pages. In most cases, such scams are sent via emails or websites. The information that the user enters on the webpage gets recorded by the phisher for misuse.
3. SQL Injection: In SQL injection attacks, hackers place wrong instructions into a website’s database. This enables them to read, modify, or delete information in the database which may lead to data breaches or damage the website. Due to failures in user input handling, attackers can alter SQL commands in websites to gain access to the database.
4. Cross-Site Scripting: Cross-site scripting (XSS) is a cyberattack where hackers place harmful scripts on a legitimate website. Then, they make the scripts run on the browsers of people who visit the site. The scripts take control of the browser environment on the target websites to steal data or redirect users to dangerous websites.
5. Denial of Service: A denial-of-service (DoS) attack can disrupt services by flooding a website with traffic. This can lead to the website crashing or running very slowly, cutting off access for genuine users. It is like a traffic jam on an Internet highway causing chaos.
6. DDoS Attacks: A Distributed Denial of Service (DDoS) attack is similar to a DoS attack in the fact that it aims to take a website offline, but what makes it different is that it is carried out by multiple devices at once (such as a network of compromised computers also known as a botnet). This can cause more problems and damage since the attack comes from different locations.
7. Brute Force Attacks: In brute force attacks, hackers attempt many different usernames and passwords to guess the correct one. With the help of automated tools, attackers can try out thousands or even millions of combinations within a short time frame. This can provide them access to a website’s admin area, which they can use to alter content or steal information.
