Traditionally, the Offenders (Red Team) and Defenders (Blue Team) have been considered two sides of the same security coin. While the Red team emulate an attacker exploiting a vulnerability in an organisation’s systems, the Blue team is responsible for building security controls to defend against the attackers. As both the activities are integral in improving the cyber security posture of a company, an integration between both mindsets is crucial in achieving the desired business objectives. Purple teaming process involves consistent knowledge sharing between both the Red and Blue teams for continuous process improvements:

  • Defence informs the offence about their controls, monitoring and how to respond to the security incidents.
  • Offence on the other hand, informs defence about TPPs (Techniques, Tactics and Procedures).

Is it possible to calculate the return of investment on cybersecurity controls?

Traditionally, organisations have struggled to calculate the financial losses from cyberattacks/ fraud and prioritise security investments based on Return of investment (ROI). Frameworks such as APRA CPS 234 demand regulated entities to maintain information security capability commensurate with information security vulnerabilities and threats. However, the APRA CPS 234 framework doesn’t provide enough information to articulate cyber risks in financial metrics with which business executives and board are familiar with. FAIR is one framework that helps quantify the risks and measure the expected financial loss due to a cyber attack.

Often, when it comes to security technologies, organisations are forced to accept the “it works, just trust us” marketing copy without ever being able to validate their effectiveness within their own environment. Thus, despite knowing the security flaws, many organisations fail to detect intrusions. Offensive security testing (i.e. Penetration tests or Red Team exercises) pinpoint many security flaws but leave it up to the organisations to fix them alone. None of these tell the IT department how to improve their tools to detect breaches or how to detect them faster. Privasec’s Breach and Attack Simulation on the other hand focuses on helping your organisation to fine tune your tools and processes and trains your SMEs to detect when you are actually under attack.
