This framework provides a set of methodologies used for web application penetration testing, mobile application penetration testing, API penetration testing, and even IoT penetration testing. Using the OWASP as a testing methodology can not only help identify vulnerabilities commonly found within modern applications, but also complicated logic flaws that stem from unsafe development practices. The frequently updated guide provides comprehensive guidelines for each penetration testing method, including a series of steps and assessments to perform, allowing testers to identify vulnerabilities within a wide variety of functionalities found in modern applications today.

With the help of the OWASP methodology, organizations are better equipped to secure their applications – web and mobile alike – from common mistakes that can have a potentially critical impact on their business. Organizations looking to develop new web and mobile applications should also consider incorporating these standards during their development phase to avoid introducing common security flaws.

OWASP Top 10:  The OWASP Web Top 10 serves as the go-to guide for web application security. This list encapsulates the most critical web application security risks such as Injection Flaws, Broken Authentication, Sensitive Data Exposure, and Cross-Site Scripting (XSS).

OWASP Mobile Top 10: The OWASP Mobile Top 10 addresses the unique challenges in mobile application security, ensuring robust defense mechanisms against mobile-specific vulnerabilities.. It covers risks like Insecure Data Storage, Insecure Communication, and Insecure Authentication.

OWASP API Top 10: The OWASP API Top 10 targets the security of Application Programming Interfaces (APIs), crucial for modern software communication. It highlights risks such as Broken Object Level Authorization, Excessive Data Exposure, and Injection.

OWASP IoT Top 10: The OWASP IoT Top 10 is tailored to the Internet of Things (IoT) devices, concentrating on vulnerabilities like Weak, Guessable, or Hardcoded Passwords, Insecure Ecosystem Interfaces, and Lack of Secure Update Mechanism.

OWASP LLM App Top 10: Securing Large Language Models The OWASP LLM App Top 10, a recent addition, focuses on security concerns specific to Large Language Models (LLMs) applications. It encompasses risks such as Data Poisoning, Inference Attacks, and Bias and Fairness issues.

3. MITRE ATT&CK

The MITRE ATT&CK framework has become a cornerstone in understanding modern security threats, allowing security professionals to replicate attacker techniques. This framework assists organizations in identifying vulnerabilities and developing tailored counter-measures:

  • ATT&CK for Enterprise: covers adversarial behavior in Windows, Mac, Linux, and cloud environments.
  • ATT&CK for Mobile: focuses on Android and iOS systems.
  • ATT&CK for ICS: targets industrial control systems (ICS), detailing potential adversarial actions.

4. NIST

The NIST 800-115 testing methodology, developed by The National Institute of Standards and Technology (NIST), is an essential resource for organizations aiming to bolster their information security. This comprehensive guide distinguishes itself by offering a structured and repeatable framework for conducting thorough security assessments. It ensures consistency and effectiveness in testing, a critical factor in the ever-evolving landscape of cybersecurity.

Key aspects of the NIST 800-115 methodology include:

  1. Structured Approach: It emphasizes a methodical process in security assessment, covering planning, execution, and post-execution analysis. This structure helps organizations systematically address potential security vulnerabilities.NIST Methodology
  2. Diverse Testing Methods: The methodology incorporates various testing and examination methods, such as technical testing, examination, and interviewing. This multifaceted approach enables a more thorough evaluation of security controls.
  3. Risk Identification and Mitigation: A primary goal of NIST 800-115 is to help organizations identify technical vulnerabilities, validate them, and develop strategies to mitigate associated risks, leading to a strengthened security posture.

Other NIST frameworks are often used alongside the NIST 800-115 standard to help implement robust defense against a wide array of cyber threats, such as:

  • NIST Cybersecurity Framework (CSF): This framework complements the 800-115 by offering a broader perspective on managing cybersecurity risks, especially in critical infrastructure sectors.
  • NIST 800-53 (Security and Privacy Controls for Federal Information Systems and Organizations): This standard provides a comprehensive set of security controls that can be used to bolster system security, ensuring robust preventive measures are in place.
  • NIST 800-171 (Protecting Controlled Unclassified Information in Nonfederal Systems and Organizations): This standard helps non-federal entities protect sensitive information and ensure secure handling of data.

5. PTES

The PTES Framework (Penetration Testing Methodologies and Standards) highlights the most recommended approach to structure a penetration test. This standard guides testers on various steps of a penetration test including initial communication, gathering information, as well as the threat modeling phases.
