Cybersecurity with Craig Petronella - CMMC, NIST, DFARS, HIPAA, GDPR, ISO27001

What if you had a front-row seat to one of the most riveting stories in cybersecurity today? Join us as we unravel the story of the Chinese state-sponsored Advanced Persistent Threat, BlackTech, and their exploitation of the Cisco Zero Day CVE 2023-20109. We dissect their strategy of modifying router firmware on Cisco routers, maintaining a stealthy persistence, and pivoting from international subsidiaries to headquarters in Japan and the U.S. We also shed light on their target: branch routers and the abuse of trusted relationships within corporate networks. In addition, we touch on the recent ransomware attack that Johnson Controls faced and the FBI's warning about dual attacks with diverse ransomware variants.
As we navigate the dense terrain of cybersecurity, we promise to enlighten you on network segmentation, a crucial measure for enhanced security and cost savings. We will guide you on creating network enclaves to handle sensitive information securely and discuss the benefits of firewall and switch segmentation for absolute separation of network communications. Furthermore, we emphasize the importance of adhering to the latest security standards like CMMC for better compliance. This episode is a goldmine of practical solutions for network security, making it essential for anyone who lives in the digital world. Stay tuned for this enlightening experience on the pressing issues in cybersecurity today.
