A website is secure as its weakest link. This is why website vulnerability testing is so important. Identifying and fixing vulnerabilities on your website can help protect your business reputation and customers' data.
In this blog post, we will discuss what website vulnerability testing is, how it works, and the types of tests that are performed. We will also provide a list of tools that you can use to perform vulnerability testing on your website.
What is website vulnerability testing?
Website vulnerability testing is the process of identifying, assessing, and remedying security flaws in a website or web application. This testing can be performed manually or with automated tools.
How does it work?
Website vulnerability testing works by identifying potential security weaknesses in a website or web application and then by guiding how to fix those vulnerabilities.
To test for vulnerabilities, security researchers will use a variety of tools and techniques. These tools can be used to identify potential weaknesses in the code, configuration, or architecture of a website or web application.
Once these potential vulnerabilities have been identified, the researcher will attempt to exploit them to see if they can gain access to sensitive data or cause other damage.
For testing the vulnerabilities, testers will attempt to exploit weaknesses in the system. It can be done by sending malicious requests to the server or by trying to access sensitive information that is not meant to be publicly accessible.
Importance of website vulnerability testing
Just as checkups and screenings are important for our physical health, website vulnerability testing is critical for the health of our online presence. By identifying and addressing potential security vulnerabilities, one can easily protect the websites from attacks that could jeopardize the safety of our data and the privacy of our users.
Ideally, website vulnerability testing should be an ongoing process. However, many organizations only test their websites on an ad hoc basis, usually in response to a specific incident or threat.
While this reactive approach may be sufficient in some cases, it does not provide the comprehensive coverage that is needed to identify all potential vulnerabilities. For this reason, it is generally recommended that organizations implement a regular schedule of website vulnerability testing.
One way to determine how often to test your website is to consider the rate at which new vulnerabilities are being discovered. On average, over 8,000 new security vulnerabilities are disclosed each year.
This means that even if you teste your website quarterly, the chances are good that there would be new vulnerabilities to assess each time you tested. As a result, many experts recommend conducting weekly or even daily scans of your website.
There are a variety of different methods that can be used for website vulnerability testing, including manual testing and automated scanning.
Automated scanning is often the quickest and most effective way to find vulnerabilities, but it is important to select a reputable scanner that is regularly updated with the latest security threats.
Manual testing can also be very effective, but it is more time-consuming and requires a greater knowledge of web application security. Whether you choose to use manual or automated testing, regular website vulnerability testing is essential for keeping your site secure.
List of tests performed
Many different types of tests can be performed as part of a website vulnerability assessment. Some of the most common tests include:
SQL Injection Testing
This test is designed to find vulnerabilities that allow attackers to inject malicious SQL code into a database.
Cross-Site Scripting Testing
This test is designed as a way to find vulnerabilities that hackers can use for malicious attacks.
Denial of Service Testing
This test is designed to find vulnerabilities that allow attackers to disrupt service by flooding a server with requests.
Remote File Inclusion Testing
This test is designed to find vulnerabilities that allow attackers to include remote files on a server.
Types of web vulnerability testing
There are two major categories of web vulnerability testing:
- Internal Vulnerability Testing
- External Vulnerability Testing
With internal vulnerability testing, the testing is done by an internal team within the organization itself.
This helps the organization assess any vulnerabilities within their firewall and see if there are areas of improvement in security, improper access management, which could lead to misuse of user privileges, and so on.
External vulnerability testing is more comprehensive and conducted by an external team that is hired by an organization to assess its security. These testers behave more like actual hackers since they do not have any inside knowledge of the website's security measures in place.
They also check the extent to which a vulnerability can be exploited to gain private data. This kind of testing leads to a well-rounded assessment of a website's security and vulnerabilities found in it.
These vulnerabilities are then mentioned in their report with CVSS scores indicating their severity based on which remediation measures can be taken.
Tools for vulnerability testing
There are a variety of different tools that can be used for website vulnerability testing. Some of the most popular tools include:
Astra's Pentest Suite
Provides a comprehensive continuous scan of a security system to find vulnerabilities other pentests may miss. It has an extensive vulnerability database through constant surveillance and updates based on intel and CVEs.
It provides a scan behind logins, critical APIs, and better security management. This tool can also be seamlessly integrated into an organization's CI/CD pipeline.
Acunetix Web Vulnerability Scanner
This scanner uses a unique crawler engine that can crawl and scan single pages, as well as entire websites.
In addition, Acunetix WVS includes an automated SQL injection engine that can find and exploit SQL injection vulnerabilities. This scanner is an essential tool for any organization that needs to secure its web applications.
Qualys SSL Labs
This service provides detailed information about the SSL/TLS configuration of a website to find vulnerabilities or potential misconfigurations.
Additionally, information about a website's HTTP strict transport security status is also identified by the tool. This is relevant since it prevents the protocol downgrade of a website.
This tool ensures compliance and provides easy, intuitive testing of websites to find vulnerabilities within them. The testing tool can also detect SQL injection attacks and deliver appropriate plugins that protect against malicious attacks.
Burp Suite is also extensible, allowing users to create their custom tools and workflows. Overall, Burp Suite is a powerful and versatile tool that can be used to great effect in a wide range of situations. It is also capable of integration with Jira for simple ticket generation.
This scanner is designed to find a wide range of web application vulnerabilities, including SQL injection and cross-site scripting. This tool can also be used to find forgotten or lost web assets and provides integrative opportunities with JIRA, Okta, and more.
This tool is designed to find a wide range of vulnerabilities, including those that can be exploited to gain access to sensitive data.
It includes many features, including an automated scanner and a manual testing environment.
If you are concerned about the security of your website, we recommend that you perform regular vulnerability testing, even if you are developing your site for the first time. Vulnerability testing is an important part of website security.
