Red team VS Blue Team Cyber Security: We Choose Purple

Cyber security is an ever-evolving landscape. IT teams and business leaders alike are constantly on the lookout for ways to improve their data security. With so many options, it can be difficult to navigate the best security solution for you. Today, we explain the differences between the frequently used terms ‘red team’ and ‘blue team’, whilst highlighting our combined solution as a ‘purple team’ cyber security provider.   

Cyber Security Teams Red Team vs Blue Team vs Purple Team Cyber Security

What Is 'Red Team' Cyber Security?

In the military, a ‘red team’ is a group of experts who test and improve their capabilities by providing security feedback from an antagonist’s perspective. The same concept is applied to cyber security. 

However scary it may sound, red teaming does not pose a threat; it does quite the opposite. By ethically hacking an organisation’s infrastructure, security vulnerabilities can be identified and patched (fixed) before a malicious hacker gets there first, potentially saving an organsiation from a future cyber attack. 

Red team engagements differ from client to client but they are typically designed to test the effectiveness of the organisations security controls and defenses. In theory, it is a process of continuously learning from existing mistakes and weaknesses.  

By adopting this offensive security strategy, you can gain a realistic insight into your current security posture, creating real lessons learnt as a result. However, there is less of a consideration to the ongoing threats which may face the organsiation on a daily basis and in the long-term. 

What Is 'Blue Team' Cyber Security?

The blue team is the counterpart to the red team and is typically responsible for defending against the simulated attacks and vulnerabilities identified by the red team. 

The blue team are responsible for maintaining the security posture of an organisation or systems and preventing unauthorised access or data breaches. They typically ingest data from multiple sources within the organisation to identify unusual or malicious activity through trend analysis and threat intel comparison.

The main purpose of a blue team is to protect an organisation from external threats such as data theft,  ransomware, malware and data compromise on a daily basis. This typically takes places within a Security Operations Centre (SOC), where a team of security professionals will be offering your organisation around-the-clock security monitoring. 

The 'Red Team' VS 'Blue Team' Debate - Is It Relevant?

The ‘Red Team’ vs ‘Blue Team’ debate has been around for a long time, but is it still relevant in today’s cyber security landscape? The answer is yes. However, the security industry does not view these solutions as an ‘either/or’ approach, but more of one in which both complement each other. Both red and blue teams can add great value to an organisation and the solution you choose depends on your organisations specific goals and needs in that moment. 

Why We Choose the 'Purple team'

At Riela Cyber, we strive to provide organisations with the clearest possible picture of their cyber security posture, their flaws and areas of improvement, whilst also defending the organisation from ongoing risks in both the internal and external environments. No business is the same and therefore these solutions must be carried out in proportion to the organisation’s needs, which often involve a combination of red/blue tactics, creating the third and final ‘team’, purple.  

The purple team bridges the gap between the red and blue team and represents the best of both worlds in terms of cyber security. Ideally, the purple team should be a permanent dynamic between red and blue.

To conclude, both red and blue teams have their place in today’s cyber security landscape, and both teams can learn from each other. Ultimately, the only ‘right’ answer is the one that works best for you and the needs of your organisation, no matter what colour that may be.
