Web Application Assessments: Everything You Need To Know

InIn today’s technology-driven world, web applications have become an essential component of our daily routines. People rely on them for daily activities like online shopping, financial management, and running business operations. However, as we and many other Cybersecurity Professionals have seen, an increasing number of web-based applications has its downsides. They have become more vulnerable to cyber threats.

As a result of this, web application assessments have become an essential part of any security strategy, and involves evaluating web-based applications to identify any weaknesses and potential risks that could be exploited by attackers. In this blog post, we will delve into the importance of web application assessments, the various types of assessments available, and how they can benefit businesses and organizations in safeguarding themselves from cyber-attacks.

Web application assessments are essential in ensuring the security and integrity of any online platforms. These assessments thoroughly examine the code, architecture, and configuration of a web application to identify potential vulnerabilities or weaknesses, and aims to identify and remediate any security issues before malicious actors can exploit them. This process can include a range of techniques, from vulnerability scanning, penetration testing, and comprehensive web application security assessments. A web application security assessment typically identifies vulnerabilities such as OWASP Top 10.

OWASP Top 10 Vulnerabilities in Web Applications

The OWASP Top Ten risks include:

  1. Injection
  2. Broken Authentication and Session Management
  3. Cross-Site Scripting (XSS)
  4. Insecure Direct Object References
  5. Security Misconfiguration
  6. Sensitive Data Disclosure
  7. Missing Function Level Access Control
  8. Cross-Site Request Forgery (CSRF)
  9. Using Components with Known Vulnerabilities
  10. Unvalidated Redirects and Forwards

Regular web application assessments are crucial for protecting online assets and reducing the risk of data breaches and other security incidents. Organizations can proactively protect their systems and data by identifying and remedying vulnerabilities early on. Additionally, web application assessments can assist organizations in compliance with industry regulations and standards.

Techniques

Web applications can be assessed from different perspectives using several techniques. A variety of tools and techniques are used to identify vulnerabilities. For the purpose of finding coding errors and configuration problems, this comprises automatic scanners, manual code reviews and penetration testing.

Automated Scanning: Automated testing uses specialized tools to scan the application for known vulnerabilities. These tools can identify common web application vulnerabilities such as cross-site scripting (XSS) and SQL injection. Automated scanning would normally not identify context sensitive vulnerabilities such business logic and access control issues.

Penetration Testing: Penetration testing simulates a real-world attack on the application to identify vulnerabilities that an attacker could exploit. The assessment is conducted without any credentials or access being provided that is not accessible to an adversary. The scope and depth of this assessment is limited and would normally not cover vulnerabilities that would be accessible to an authenticated user.

Authenticated Penetration Testing: Authenticated penetration testing assesses the application from perspective of an authenticated user or an insider. It is generally more in-depth and comprehensive. This approach is more thorough and can identify subtle vulnerabilities that automated tools may miss. It is also helpful in identifying business logic flaws, access control issues and other security issues that automated tools do not detect easily. However, this type of approach is typically more time-consuming and requires a skilled security professional.

Secure Code Reviews: This assessment involves reviewing the source code of the application to identify potential vulnerabilities manually with the support of automated tools. Secure code reviews aim to identify any flaws in the application’s design and implementation that an attacker could potentially exploit.

A comprehensive web application security assessment takes all the various methods mentioned above to perform a more complete assessment that provides a higher level of assurance, identifying as many vulnerabilities as possible and reducing the number of false negatives.

How is Web Application Assessment Different from Normal Network Pen Test?

Web application assessments and penetration testing (pen testing) are similar in that they both involve identifying vulnerabilities in a web application, but there are some critical differences between them.

One of the main differences is the scope and focus of the assessment. Web application assessments are typically focused on identifying and remediating vulnerabilities in the web application source code base, such as SQL injection or cross-site scripting (XSS) vulnerabilities. Web application assessments are much more in-depth assessment of the web application that normal pen tests rarely touch the surface of.

Another difference is in the approach and methodology used. Web application assessments often use a combination of manual code review, automated testing, and risk assessments to identify vulnerabilities.

Tools Used for Web App Assessments

Several tools are available for web application assessments, and the appropriate agency will depend on the specific needs and requirements of the organization. Some popular tools for web application assessments include:

  1. HCL AppScan
    • HCL AppScan is a commercial web application security scanner that can automatically find security vulnerabilities in web applications. This web security solution helps find and fix common security flaws like SQL injection and XSS by automating vulnerability detection in web applications, improving overall security posture.
  2. OpenText WebInspect
    • Micro Focus developed WebInspect, an automated web application security scanning tool designed to identify and evaluate security flaws in web applications.
  3. Acunetix
    • Acunetix is a commercial web application security scanner that is designed to recognize and evaluate security flaws in web applications automatically.
  4. Burp Suite
    • Burp Suite is a set of tools for web application security testing that includes a web proxy, a web application scanner, and a web application fuzzer.
  5. Tenable.io WAS
    • Tenable offers a web application vulnerability scanning solution through their Tenable.io platform. This tool examines the security of web apps and APIs by detecting potential vulnerabilities and misconfigurations that an attacker could exploit.
  6. OWASP ZAP
    • OWASP ZAP (Zed Attack Proxy) is an open-source web application security scanner that can automatically find security vulnerabilities in web applications.
  7. W3AF
    • W3AF “Web Application Attack and Audit Framework,” is an open-source web application security scanner that can automatically find security vulnerabilities in web applications.

These are famous and widely used tools, but many other tools are available that can be used for web application assessment. The appropriate tool for a web application assessment will depend on the organization’s specific needs, the resources available, and the experience of the security team.

Conclusion

In conclusion, web application assessments are a crucial step in ensuring the security of online platforms. They involve examining a web application’s code, architecture, and configuration to identify and remediate vulnerabilities before malicious actors can exploit them. Organizations must conduct regular web application assessments using a combination of manual code review, automated testing, and penetration testing to identify and address vulnerabilities effectively.

Organizations should make web application assessments a regular practice to proactively protect their online assets and reduce the risk of security incidents.
