What is a Blue Team Exercise?
The red versus blue team security exercise
is one of the best practices within the cybersecurity industry.
when assessing a system’s security processes. Much inspiration for this exercise was
drawn from the military-developed “wargames” model, in which two opposing teams are
subjected to various simulations and are tasked to either breach or defend a
corporation’s security systems.

The red team typically comprises technology professionals with a background in
ethical hacking, whereby they will act as imaginary malicious attackers seeking to
identify and exploit any flaws within a given security system (via ransomware, for
instance). Meanwhile, the blue team is responsible for adhering to company protocols
and policies to strengthen as well as patch up any defects in the information
technology (IT) infrastructure in order to deter any escalation of attacks across
the entire network. In essence, the main objective of the blue team is to protect
all electronic assets (for example, proprietary databases, private and confidential
information) owned by an organisation, regardless of whether it is hosted internally
(i.e., on-premise) or externally (i.e., cloud-hosted).
That being said, blue team exercises are essentially the performance of all security
operations centre (SOC) functions across multiple simulated cybersecurity threats to
evaluate the blue team’s competence at detecting, preventing, and mitigating any
forms of security breaches. Upon completion of the blue team exercise, the red team
will reveal their attack strategies and tactics, whilst the blue team will take note
of these data points to evaluate their defence mechanisms. Thus, this simulation
enables the blue team to pinpoint vulnerable areas within a business network so that
they are able to make the necessary improvements to their system. As a result,
similar attacks in the future will have a much lower chance of succeeding again.
