There are multiple teams in Cybersecurity as we all know. They are mainly divided into three teams namely red, blue, and purple teams. To understand the purple team in cybersecurity, we first need to understand the basics of the red and blue teams. The Red team simulates real-world attackers' actions and is responsible for breaking into an organization's system, while the Blue team is responsible to defend and implement countermeasures towards these attacks. The Purple team in cybersecurity performs both the functions of the blue and red teams and has the skillsets of these two teams.
"A Purple Team uses a methodology where both the red and blue team work together to provide and provide constant feedback to increase their cyber capabilities. It is a combination of both the defensive and offensive approach of cybersecurity. In addition, some of the tasks performed by the purple team are responding to cyber threats and breaches, system and DNS audits, penetration testing, vulnerability testing, and many more. To find flaws in security controls, processes, or procedures, it uses the expertise and resources of both the red and blue teams.
Traditionally cybersecurity was deemed to have an offensive and defensive team working individually. However, in more recent years, the purple team has a competitive strategy between both the red and blue teams which helps in penetrating the system to improve security. The information gathered by the purple team can be used in creating an actionable plan and with this knowledge, it can be implemented feasibly.
There are several benefits of a purple team in cybersecurity, some of which are explained briefly below:
- Simplify security enhancements: Within the branch of security, an alternate approach is to see purple teaming as a conceptual model that runs across an organization. This can encourage a collaborative environment that supports ongoing cybersecurity progress.
- Improves the ability to detect vulnerabilities: Purple team can assist security experts to gain a better understanding of how attackers think and work, making it more easier to discover possible vulnerabilities before they are exploited. Both teams acquire a better grasp of an organization's broader security posture.
- Better time management: In cybersecurity, time is a valuable asset when offensive and defensive professionals collaborate in a purple team, they save time to find and patch vulnerabilities more rapidly. The purple team is not only safer, but it is also more efficient and quicker.
- Helps in obtaining useful insight: Purple teaming helps discover opportunities for capacity development by providing your internal security team with a key awareness of gaps in your security posture.
Purple teaming is utilized by certain organizations as one-time, targeted engagements with well-defined security objectives, time frames, and key deliverables. These engagements also include a structured methodology for assessing information gained throughout an operation. This involves identifying offensive and defensive weaknesses as well as future technical and training requirements. The main objective of the purple team is to strengthen your company’s security posture by combining the red and blue teams.
