Application Allow Listing, iMessage Post Quantum

Blue Security

Summary

In this episode, Andy and Adam discuss the concept of application allow listing and the controversy surrounding the removal of Wireshark from company computers. They also delve into the announcement by Apple that iMessage is moving to post-quantum level 3 encryption, making it one of the most secure messaging apps available. The hosts highlight the importance of communication and risk assessment in the field of information security. They also emphasize the need for organizations to have backup communication plans during incidents. The episode concludes with a discussion on the future of post-quantum encryption and its potential impact on the industry.

Takeaways

-Application allow listing allows organizations to control the software installed on company assets for security and productivity purposes.

-InfoSec teams have the right to evaluate and remove applications with high vulnerabilities or CVEs, but there should be an exception process for legitimate business needs.

-Apple's announcement of iMessage moving to post-quantum level 3 encryption highlights the importance of quantum-resistant encryption in the face of future threats.

-iMessage's widespread use in the United States makes its security upgrades significant for communication privacy.

-The implementation of post-quantum encryption at scale by Apple sets a precedent for the industry and may lead to broader adoption of quantum-resistant encryption methods.
