Blue Team Cybersecurity

A designated Blue Team exists to defend against attackers (black hat hackers) while continually improving an organization’s security posture. Blue Team cybersecurity professionals are expected to determine false positives while reacting quickly to any possible malicious events. During a malicious event the blue team is required to operate efficiently using defensive procedures.

The Blue Team must host recap meetings that enable procedures, policies, and documentation to be updated—especially after a security event. It is extremely important for any organization whose infrastructure interacts with the internet to be thoroughly tested and validated for its current security hygiene on a regular basis.

Threatcare, the leader in Breach and Attack Simulations, offers the Threatcare app. Threatcare is a desktop application that combines the initiatives of a blue and a red team to act as a virtual purple team. Threatcare can execute Breach and Attack Simulations as well as a wide variety of other simulations to test your defense in depth. Threatcare can be downloaded for free here.

Blue Team Goals  

An organization’s Blue Team should fully understand how its own share of the security stack operates. This includes not just security software (IDS, IPS, SIEM, UTM, NGFW, DLP), but also the languages and frameworks that their enterprise software stack is comprised of.

A Blue Team’s security stack should include software offerings to help identify what activity should and should not be present. This should be done through the proper use of solutions like intrusion detection systems (IDS) to notice suspicious traffic patterns. Blue Team’s that can identify indicators of compromise (IOC) leverage the most important task to mitigating any compromise, which is actually seeing a attack as it begins.

Blue Team cybersecurity professionals don’t just stop attackers as they appear, they also work towards long term incident detection & response (IDR) with plans to preserve evidence and minimize downtime. These plans include, but are not limited to:

  • Log Analysis
  • Disk and File Analysis
  • Memory Analysis
  • Packet Capture (PCAP) Analysis

Blue Team’s must gather computer forensics to identify threats, and use the best mitigation approaches available to halt an attack. It’s not a best practice to wait mid-incident to become familiar with processes for forensics.

A strong Blue Team regularly practices defending their network using planned procedures against external Red Teams. Producing simulated real-life intrusion scenarios with the Red Team yields mature IDR processes and disaster recovery (DR) plans. The intrusion simulations help familiarizing the Blue Team with best practices for recovery time objective (RTO) and recovery point objective (RPO). RTO defines how long an organization’s network can be shut down due to an attack before substantial cost occurs. RPO can exemplify how much of the original data should be backed up, or at what point the organization should stop their query for backed up data.

Blue Teams should have access to multiple software security solutions. It is for this reason that the Threatcare Suite is crucial for security practitioners to use to quickly test the effectiveness of their products, and current level of protection.
