Application security assessments are comprehensive evaluations of software applications designed to identify and address potential security vulnerabilities and risks. These assessments involve a systematic and thorough analysis of the application's architecture, design, code, and configurations to identify weaknesses that attackers could exploit. There are several types of application security assessments. To help you determine what type of assessment is right your organization, the Fortalice blog outline four of the most common types: Manuel Code Reviews, Automated Vulnerability Scanning, Penetration Testing, and Security Architecture Reviews.

Manual Code Reviews

Manual code reviews play a crucial role in application security assessments. They involve a meticulous and detailed examination of the application's source code by skilled security professionals or code reviewers. The purpose of manual code reviews is to identify coding errors, vulnerabilities, logic flaws, and other security-related issues that may not be easily detected through automated tools or scanning techniques.  

During a manual code review, the reviewer analyzes the code line by line, seeking to uncover vulnerabilities that attackers could potentially exploit. The reviewer focuses on understanding the application's logic, data flow, input validation, error handling, and access control mechanisms. By delving into the code, manual reviewers gain deep insights into the inner workings of the application, allowing them to identify potential security weaknesses.

Manual code reviews can uncover a wide range of security issues, including injection attacks, cross-site scripting (XSS), improper authentication and authorization, insecure cryptographic implementations, and data leakage vulnerabilities. They also help identify coding best practices that may have been overlooked, such as input sanitization, output encoding, secure coding patterns, and secure configuration settings.

One of the main advantages of manual code reviews is the human factor. Skilled reviewers bring their expertise and experience to the process, leveraging their knowledge of common attack patterns and secure coding practices. They can spot subtle vulnerabilities, complex logic flaws, and potential business logic abuse scenarios that automated scanning tools may not easily detect.

However, it's important to note that manual code reviews can be time-consuming and resource-intensive, especially for larger codebases. They require skilled professionals who have a deep understanding of programming languages, secure coding practices, and common vulnerabilities. Collaboration with developers and the application's development team is also essential to gain a comprehensive understanding of the code and ensure effective remediation of identified issues.

Overall, manual code reviews provide a valuable layer of scrutiny in application security assessments. They complement automated scanning techniques, enhance the detection of vulnerabilities, and contribute to the overall security and integrity of the application's source code.

Automated Vulnerability Scanning

In contrast to manual security reviews, vulnerability scanning relies on the use of specialized tools to automatically scan and analyze the application's code, configurations, and network interactions to identify potential security vulnerabilities.

Automated vulnerability scanners are designed to detect common security weaknesses and known vulnerabilities within the application. These scanners employ a variety of techniques, including static analysis, dynamic analysis, and black-box testing, to uncover potential issues.

Static analysis focuses on analyzing the application's source code, binaries, or compiled files without executing them. It searches for coding patterns, insecure coding practices, and potential vulnerabilities that may exist within the codebase. Static analysis scans can help identify issues such as SQL injection, XSS, or insecure cryptographic implementations.

Dynamic analysis, on the other hand, involves executing the application and interacting with it to identify vulnerabilities during runtime. This type of scanning can uncover issues like improper input validation, insecure session management, or access control weaknesses. Automated vulnerability scanners also perform black-box testing, where they simulate attacks by sending malicious requests to the application and observing the responses. This helps identify vulnerabilities from an attacker's perspective without relying on access to the application's source code.

Automated vulnerability scanning offers several benefits in application security assessments. It is efficient, as it can quickly scan large codebases and provide a comprehensive report of identified vulnerabilities. It also helps identify common and well-known security issues, reducing the risk of overlooking important vulnerabilities. However, it is important to note that automated scanning has some limitations. It may generate false positives or false negatives, requiring human validation and interpretation. Automated tools may not always detect complex logic flaws or business-specific vulnerabilities that require a deeper understanding of the application's context.

To maximize the effectiveness of automated vulnerability scanning, select and configure reputable scanning tools, keep them updated with the latest vulnerability databases, and integrate them into the overall application security assessment process. Combining automated scanning with manual code reviews and other assessment techniques helps ensure a comprehensive evaluation of the application's security posture.

Penetration Testing

Penetration testing, also known as ethical hacking, is a critical component of application security assessments. It involves simulating real-world attacks to assess the security of an application and identify potential vulnerabilities and weaknesses.

In the context of application security assessments, penetration testing focuses on identifying vulnerabilities that may not be easily detected by automated scanning tools or manual code reviews alone. These tests aim to uncover potential security flaws and assess the impact of those vulnerabilities on the application's security posture.

During a penetration test, skilled professionals, known as penetration testers or ethical hackers, attempt to exploit identified vulnerabilities to gain unauthorized access, manipulate data, or perform actions that an attacker could potentially carry out. This active testing approach provides a deeper understanding of the application's security by simulating real-world attack scenarios. Penetration testing may involve various techniques, such as SQL injection, XSS, privilege escalation, or session hijacking. It may also include social engineering tactics to test the effectiveness of security controls and user awareness.

The outcomes of a penetration test provide valuable insights into the vulnerabilities that could be exploited, the potential impact of successful exploitation, and the effectiveness of existing security controls. This information helps organizations prioritize remediation efforts, improve their security posture, and strengthen the resilience of their applications against potential threats.

Penetration testing should always be conducted with proper authorization and within defined rules of engagement to ensure the security and privacy of the application and its data. Collaboration with the organization's developers and security teams is essential to address identified vulnerabilities effectively while implementing appropriate remediation measures.

Overall, penetration testing is a proactive and dynamic approach to assessing the security of an application. It complements other assessment techniques, such as automated vulnerability scanning and manual code reviews, to provide a comprehensive evaluation of the application's security posture and identify potential vulnerabilities that attackers could exploit.

Security Architecture Reviews

Security architecture reviews are another essential component of application security assessments. These reviews focus on evaluating the overall security design of an application. It involves a systematic examination of the application's security controls, authentication mechanisms, access controls, data protection measures, encryption algorithms, and integration with external systems.

The purpose of a security architecture review is to assess the application's resilience against potential threats, identify potential design flaws, and ensure that appropriate security measures are in place to protect the application and its data. During a security architecture review, security professionals analyze the application's architecture, network topology, and data flow diagrams. They assess whether the application follows secure coding practices, adheres to industry standards and best practices, and aligns with relevant security frameworks.

By conducting a thorough security architecture review, organizations can identify potential design flaws, gaps in security controls, or misconfigurations that may expose the application to security risks. The findings of the review help to provide recommendations and guidance for improving the application's overall security posture, ensuring that it aligns with industry best practices and standards.

It is important to note that a security architecture review is an iterative and ongoing process as security requirements and threats evolve over time. Regular reviews and updates to the application's security architecture are necessary to address emerging risks and maintain a strong security posture.


The outcomes of application security assessments typically include detailed reports that outline the identified vulnerabilities, their severity, and recommendations for remediation. Organizations can then prioritize the identified issues and implement appropriate measures to mitigate risks and strengthen the security of their applications.

Regular application security assessments are crucial in maintaining a strong security posture for software applications. By proactively identifying and addressing vulnerabilities, organizations can protect sensitive data, prevent security breaches, comply with regulations, and build trust with their users and customers.
