por If you have heard about the Blue Team and the Red Team, you will surely wonder What is Purple Team in cybersecurity. As you know, the Red Team and the Blue Team are responsible for the offensive and defensive security of a company, respectively. Therefore, could the Purple Team be understood to be a mix between the two?
In reality, the definition of Purple Team is more complex, it is not the mix between the Red Team and the Blue Team. The Purple Team is not only the one that performs functions of the other two teams, but it is also the one that facilitates communication and optimizes performance between them.
Blue Team vs Red Team
Before seeing what Purple Team is in cybersecurity, you should know the different functions of the Blue Team and the Red Team.
Blue Team
He Blue Team either Blue Team takes care of the defensive security of the company. It can be made up of people internal or external to the company and its function is to keep its computer system secure.
The Blue Team monitors and performs frequent security checks. This safety equipment also is responsible for performing forensic analysis and developing patches to solve possible errors. However, how do you discover the vulnerabilities of a system, if not by trying to attack it? That’s where the role of the Red Team comes into play.
RedTeam
He Red Teamthe opposite of blue teamsemulates the attackers, because Its function is to simulate attacks against an organization, in order to detect and report vulnerabilities in its systems.
The Red Team checks the ability to detect and respond to possible weak points in the organization’s system. To do this, it uses hacking and social engineering tools and tactics. In short, this team carries out offensive security tasks, testing the company’s security measures through all the attack vectors possible.
What is Purple Team in cybersecurity?
We could think that the Purple Team is just a mix between the Red Team and the Blue Team. That is, a team that is in charge of simulating attacks and, at the same time, monitoring and strengthening the security scheme. security of the organization.
However, the definition of what Purple Team is in cybersecurity and the purple hacker goes beyond a simple mix between the two previous teams. Sometimes, The Purple Team can be a small security team, made up of a few members who play the roles of both the Red Team and the Blue Team, although this does not imply that the function of the Purple Team is reduced only to these cases.
purple team definition
In the most complete security equipment, The function of the Purple Team is to maximize the effectiveness of the Red Team and the Blue Team through the development of common objectives, as well as facilitating communication between both groups.
He Blue Team and the RedTeam of a company, whether external or internal, could not having proper communication with each other. This lack of communication can lead to low efficiency in improving the company’s security. Therefore, the Purple Team helps optimize performance of the Blue Team and the Red Team.
Is it necessary to have a Purple Team?
Taking into account the goals of the Red Team and the Blue Team, it is understandable the importance of communication between both teams. Above all, it is evident that members of the Red Team must exhaustively report bugs to the Blue Team, so that solutions can be developed. However, the following question arises: Should the Blue Team communicate its security improvements to the Red Team?
In effect, this would give the Red Team an advantage in making their simulated attacks. Nevertheless, This would serve to take the company’s cybersecurity further. The deeper the attack the Red Team develops, the more information the Blue Team will have to reinforce its system. In relation to this information and objectives management is the great importance of knowing what it is PurpleTeam in cybersecurity.
Other types of equipment
In addition to knowing what Purple Team is in cybersecurity, you will also see that there are other equipment with more specific functions, which do not make up the red blue purple team
Threat Hunting
This subdivision of the Blue Team is in charge, as its name indicates, of the active threat hunting to isolate them from the systems we seek to protect. What differentiates this team from the Blue Team is the proactivity in the search for possible cyber attacks. The other defense strategies are based, above all, on the detection and response of attacks, after they have occurred.
CERT
He Computer Emergency Response Team (CERT) specializes in responding to attacks and threats. It can also be considered as a branch of the Blue Team in charge of resolve incidents. An example of one of these teams is the CERT of the National Cryptology Center of Spain, which organizes CTF courses and games for the cybersecurity community.
CSIRT
He Computer Security Incident Response Team (CSIRT), Like the CERT, it is also an incident response team. However, these apply, above all, to governments, politics and the business world.
