Purple teaming is a security practice in which red and blue teams collaborate closely to maximize cyber capabilities through constant feedback and information sharing. The concept was developed by John Arquilla and David Ronfeldt in their 2001 book, "Cyberwar: How Conflicts on Internet Networks Will Be Waged and Won".
According to the authors, purple teaming involves "the coordinated use of red teaming and blue teaming skills by a single organization or group for the purpose of enhancing cybersecurity capability."
The name "purple team" comes from the fact that these teams will typically include members who are skilled at different types of attacks (i.e., red team members who can conduct resource-intensive attacks, blue team members who can perform more targeted attacks).
Typically, the goal of a purple team is to identify weaknesses within an organization's cybersecurity defenses and then work with those defenses' designers to come up with solutions that will prevent those defenses from being exploited.
John Arquilla has said that purple teaming is not a new idea but it is becoming more popular now because organizations realize they need multiple types of expertise to successfully attack themselves.
The Purple Teams are intended to improve information exchange between the Red and Blue teams in order to optimize their individual and collective effectiveness. The purpose of each meeting is determined by the group's leadership, which can include one or more persons named by the manager, who may also be referred to as the facilitator.
There are two types of meetings: status meetings and planning meetings. At a status meeting, members report on what they know about the case that is currently being handled by their team. They may make recommendations regarding changes to how the case should be handled. For example, a member of the Blue Team might suggest that the case be sent to the Red Team for additional analysis. Alternatively, someone from the Red Team might ask for suggestions on how to better approach the case.
At a planning meeting, the group discusses issues related to multiple cases. They may discuss trends that they have observed during previous cases or questions that have been raised by other groups. Also included are any actions that need to be taken by others within the department or organization.
A red team exists to attack, whereas a blue squad exists to protect. The goal is to improve an organization's security by learning from the subsequent conflict. A "purple team" is optionally formed to assist with the procedure. It consists of people who possess some type of authority within the organization.
To understand how an attacker might approach a system, we need to know what they are trying to achieve. They will want to find vulnerabilities that allow them to accomplish this objective. We can use a red team to identify these problems before an intruder does. A red team can also help an organization understand how effective their defenses are at preventing attacks.
A red team is made up of security professionals who will use the knowledge gained to attack a target. This group will attempt to break into systems, install malware, or otherwise test the security of an organization's assets. After completing their tasks, the members of the red team will discuss their findings in order to learn more about possible improvements for security procedures.
The leader of the red team should have experience in security research and testing. They should be able to identify potential problems with a system and then develop strategies to discover those issues.
Purple represents a cooperative spirit shared by attackers and defenders on the same team. As such, it should be regarded as a function rather than a distinct team. It is used in various international sports leagues including the NFL, NBA, and NHL.
The name "Team Purple" was first used by the National Football League (NFL) when they created an all-defensive team to face the all-offensive teams in 1958. The idea came after the then-current defensive champion Cleveland Browns had lost to the offensive powerhouse Chicago Bears 26-6. To make up for it, the NFL formed a new all-defensive team - the Baltimore Colts - which went on to win the championship that year. From then on, the all-defensive team would receive the designation of "Team Purple".
There are two reasons why we use purple in CakePHP: first, it's the default color of CakePHP applications; second, it has some special meaning for us.
CakePHP is based on PHP and uses the MVC (model-view-controller) pattern. This means that every page rendered by your application is given to the view layer, which determines what HTML is sent to the browser and how it looks.
Because the primary aim of a red team is to identify methods to enhance the blue team, purple teams are unnecessary in companies where the red team/blue team connection is healthy and functional. The finest use of the word, in my opinion, are when a group that is unfamiliar with offensive strategies seeks to learn about how attackers think. A purple team can help bring this awareness out of them.
The reason why purple teams are useful is because they allow an organization to understand its own vulnerabilities even better. By having a separate team that focuses on attacking the organization, you can see what types of systems are most vulnerable to attacks and address those issues before more damage is done.
In addition, having a purple team allows an organization to explore new techniques and technologies that could be beneficial for itself or others in the community. For example, a technology that seems like it would be effective in preventing blue team attacks may actually be used by the purple team to attack the blue team themselves. This discovery could lead to improvements that benefit both the blue and purple teams.
Finally, having a purple team allows an organization to learn from its mistakes. If an attack is successful, the perpetrators can be identified by the purple team and lessons learned from the incident used to protect other individuals or groups within the company.
Overall, purple teams are a valuable tool for organizations to use to improve their security defenses.
