Red-team assessments have limitations when it comes to validating the effectiveness of defenses, leaving defenders uncertain about their strength [1]. This is due to their focus on specific attack techniques and variations, without providing information about other techniques or varieties [2].

Description

Red teams only test a limited number of attack variants, which makes it difficult to accurately judge defense strength. Defenders are left unsure if their defenses are lacking or if the red team simply chose an unprepared option [1]. To address this, purple teams [1] [2], which involve collaboration between red and blue teams [1] [2], have been introduced as a step in the right direction. However, they still have limitations [2].

To improve threat detection [1] [2], it is crucial to build representative samples that cover a wider range of attack possibilities [1]. This will help verify that vendors have comprehensive detection for the behaviors they claim to stop [2]. Currently, the industry lacks a comprehensive system for categorizing and naming attack details [1].

Conclusion

The limitations of red-team assessments and the need for comprehensive threat detection are important considerations for defenders. Collaboration between red and blue teams [1] [2], as seen in purple teams, is a positive step forward. However, building representative samples that cover a wider range of attack possibilities is crucial for improving threat detection [1] [2]. Additionally, the industry needs to develop a comprehensive system for categorizing and naming attack details to enhance defense strategies.
