How to Assess Your Website For Technical Vulnerabilities?

How to assess your website for technical vulnerabilities?

A website is much like a building; it requires maintenance, repairs, and occasional upgrades. But unlike a physical structure, conducting an audit of your website’s technology can be very difficult. This is especially true if you don’t have strong technical skills in the area. It’s important to understand the technical vulnerabilities of your website so that you can protect your business from any potential cyber threats or data breaches. In this blog post, we’ll look at how to assess your website for technical vulnerabilities and ensure its security. We’ll discuss why vulnerability assessment is essential, as well as the methods and steps you can take to protect yourself online.

Types of Technical Vulnerabilities

There are many different types of technical vulnerabilities that can affect a website. Some of the most common include

File inclusion vulnerabilities: These types of vulnerabilities allow an attacker to include arbitrary files on the server, which can lead to server compromise or data disclosure.

Directory traversal vulnerabilities: Directory traversal attacks allow an attacker to access files and directories that they should not have access to. This can lead to sensitive information being disclosed or the execution of malicious code on the server.

Insecure configuration: Websites that are poorly configured are often more susceptible to attack. For example, leaving debugging information enabled or using weak passwords can give attackers an easy way in.

A. Injection Flaws

Injection flaws are one of the most common types of web application security vulnerabilities. They occur when user-supplied input is not properly sanitized before being used by the application. This can allow attackers to inject malicious code into the application, which can be executed by the server and used to compromise the security of the application.

There are many different types of injection flaws, but they all share a common goal: to execute malicious code on the server. The most common type of injection flaw is SQL injection, which occurs when user-supplied input is used directly in an SQL query without proper sanitation. This can allow attackers to execute arbitrary SQL code on the server, which can be used to compromise the security of the database. Other types of injection flaws include command injection, script injection, and XML injection.

To prevent injection flaws, it is important to sanitize all user-supplied input before using it in any way. All input should be validated and filtered for potentially dangerous characters. It is also important to use parameterized queries when possible to avoid dynamic SQL queries that are susceptible to injection attacks.

B. Cross-site Scripting (XSS)

Cross-site scripting (XSS)
Cross-site scripting (XSS) is a type of security vulnerability that can occur in Web applications. XSS enables attackers to inject malicious code into Web pages viewed by other users. When a user views a page containing malicious code, the code can be executed by the browser, resulting in the execution of the attacker’s code on the user’s machine.

One common way for XSS vulnerabilities to occur is when user input is not properly sanitized before being displayed by the Web application. For example, if an attacker can trick a user into submitting malicious input (e.g., via a malicious link), and the Web application does not properly sanitize that input before displaying it, the attacker’s code will be executed on the user’s machine when they view the page.

To prevent XSS vulnerabilities from occurring, it is important to ensure that all user input is properly sanitized before being displayed by the Web application. Additionally, it is often helpful to use a web application firewall (WAF) to help protect against XSS attacks.

C. Broken Authentication and Session Management

When it comes to website security, broken authentication and session management is one of the most common vulnerabilities. This is because many websites still rely on weak and easily guessed passwords, or they don’t properly invalidate and terminate user sessions.

As a result, attackers can gain access to user accounts and data simply by brute forcing their way in, or by hijacking an active session. In some cases, they can even bypass authentication entirely.

To assess your website for this type of vulnerability, you need to check how it handles authentication and session management. Does it require strong passwords? Does it properly invalidate and terminate user sessions? Are there any ways to bypass authentication altogether?

If you’re not sure how to answer these questions, contact a web security expert for help. They will be able to perform a thorough assessment of your website and identify any potential vulnerabilities.

D. Insufficient Logging and Monitoring

Logging is a critical process for identifying and diagnosing website issues. Without proper logging, it can be difficult to troubleshoot website problems. Furthermore, detailed logging can provide valuable insights into website visitor behavior and trends.

Monitoring is also essential for keeping tabs on website performance. By monitoring key metrics such as page load times and error rates, you can quickly identify when something is wrong and take steps to fix the issue.

How to Find Technical Vulnerabilities on Your Website?

Assuming you have a website up and running, there are a few ways to find technical vulnerabilities. Below are some recommended methods:

1. Use an automated scanner – There are many commercial and free scanners available that can help you find common web application vulnerabilities. Some popular options include Acunetix, Qualys Guard, Netsparker, and HP WebInspect.

2. Review your web server and application logs – Your web server and application logs can be helpful in identifying potential vulnerabilities, such as unhandled errors or unusual user activity.

3. Perform a manual review of your code – A manual review of your source code can help you identify potential security issues, such as hard-coded passwords or insecure input handling.

4. Use a vulnerability assessment service – There are various companies that offer vulnerability assessments, which can be helpful in identifying both common and uncommon vulnerabilities.

How to Fix Technical Vulnerabilities?

There are many ways to fix technical vulnerabilities, but the most important thing is to identify them in the first place. To do this, you can perform a website security assessment. This will help you to find any potential weaknesses in your website’s design or coding that could be exploited by hackers. Once you have identified these vulnerabilities, you can then take steps to fix them. This may involve patching any holes in your code, redesigning vulnerable pages, or increasing security measures such as adding firewalls or encryption. By taking these steps, you can help to protect your website from attack and keep your data safe.

Three Methods to Identify Website Vulnerabilities

1. Identify website vulnerabilities using automated tools: There are many automated tools available that can help you identify website vulnerabilities, such as Acunetix, Nikto, and WebInspect.

2. Conduct a penetration test: A penetration test is a more in-depth assessment of your website’s security. This type of test simulates an attack on your site to identify any vulnerabilities that could be exploited by an attacker.

3. Check your website’s source code – One way to check for website vulnerabilities is to examine your site’s source code. If you see any suspicious code or files, it’s possible that your site has been compromised.


Website security is essential for any business website. Assessing your website for technical vulnerabilities will help you identify and fix issues before they cause any harm to your site or customers. By following the guidelines outlined in this article, you can make sure that your website is secure and protected from potential threats. Remember to keep an eye on new updates and developments so that you can stay up-to-date with the latest methods of assessing websites for technical vulnerabilities.
