Description: Playing with security refers to the practice of taking unnecessary risks in the realm of cybersecurity, where protective measures are ignored or underestimated. This concept manifests in the dynamic between the Red Team and the Blue Team, where the Red Team acts as the attacker, seeking vulnerabilities in systems, while the Blue Team is responsible for defending and protecting those systems. The interaction between both teams is essential for identifying weaknesses and strengthening security. However, ‘playing with security’ implies that, at times, risky decisions can be made that compromise the integrity of systems, whether due to inattention, pressure to meet deadlines, or a false sense of security. This attitude can lead to severe consequences, such as data breaches, financial losses, and damage to an organization’s reputation. A robust security culture must promote responsibility and proactivity, preventing teams from feeling comfortable ignoring best practices. In this context, it is crucial for both the Red Team and the Blue Team to work together to create a secure environment, where risks are minimized and defenses maximized, thus avoiding the danger of playing with security.
