Understanding Your Network's Security Posture: Vulnerability Scans, Penetration Tests, and Beyond

Organizations of all sizes need to be proactive in identifying and mitigating vulnerabilities in their networks. To help organizations better understand the value and process of a vulnerability scan, Trustwave’s Philip Pieterse, Managing Consultant for the Americas division of SpiderLabs and Dhervesh Singh, senior Security Consultant with SpiderLabs conducted a webinar exploring key offensive security testing methodologies: vulnerability scanning, penetration testing, and purple teaming.

A link to the webinar replay is provided below, but here is a brief overview of the areas the two discussed.


Vulnerability Scanning: The First Line of Defense

Imagine your network as a castle. A vulnerability scan is like having a scout check the walls for weak points. In the webinar, Pieterse explains that vulnerability scans are automated processes that identify open ports on your devices and match them against a database of known vulnerabilities. It's a cost-effective way to find "low-hanging fruit" – easily exploitable weaknesses. Scans can be conducted internally or externally, depending on your needs.


Penetration Testing: Going Beyond the Surface

A penetration test (pentest) is like a full-fledged siege on your castle. Here, a team of ethical hackers, similar to a skilled attacker, will try to exploit the vulnerabilities, some identified during a vulnerability scan (ideally after remediation of critical issues) or discover new ones altogether. Singh explains that pentests involve manual testing, including exploiting vulnerabilities, chaining attacks (exploiting multiple vulnerabilities together), and even attempting weak password guesses. Trustwave SpiderLabs uses a blend of publicly available tools and custom-developed techniques to simulate real-world attacks.


Red Teaming: The Ultimate Adversary Emulation

Think of red teaming as a multi-week military exercise where the enemy is constantly adapting. It's the most complex security assessment, designed to emulate the tactics, techniques, and procedures (TTPs) of a sophisticated attacker. Unlike pentesting, red teams prioritize avoiding detection by your security team (the blue team). Dhervesh highlights the extensive planning and infrastructure creation involved in red teaming. Trustwave recommends red teaming for organizations with a mature security posture and a blue team in place.


Purple Teaming: Collaboration is Key

Purple Teaming bridges the gap between red and blue teams. Philip describes it as a collaborative exercise simulating a specific scenario, like a ransomware attack. Here, the blue team knows about the exercise and actively tries to detect and stop the simulated attack. This "football team practice" approach helps improve the blue team's response capabilities.


Choosing the Right Security Assessment

The best security assessment for your organization depends on your security maturity. Here's a quick guide:

  • Start with Vulnerability Scanning: It's a cost-effective way to identify basic weaknesses.
  • Consider Penetration Testing: It provides a deeper understanding of your network's exploitable vulnerabilities.
  • Move to Red Teaming (if ready): It tests your blue team's ability to detect and respond to advanced attacks.
  • Purple Teaming can complement Red Teaming: It helps improve blue team response based on a specific scenario.
