Episode 52: Physical Security Attacks and Indicators (Domain 2)
from Certified: The CompTIA Security+ Audio Course Hosted by Dr. Jason Edwards
While cybersecurity often focuses on virtual threats, physical attacks on facilities, hardware, and access points remain a serious and sometimes overlooked risk. In this episode, we explore how physical breaches—like forced entry, badge cloning, hardware theft, or environmental sabotage—can compromise both data and infrastructure. Indicators of such attacks include damaged locks, tampered surveillance equipment, missing hardware, or anomalous badge activity, especially outside of business hours. We also look at Radio Frequency Identification (RFID) cloning, where attackers replicate access credentials, and brute-force attempts on physical entry systems. Proper monitoring, such as integrating physical and logical access logs, helps correlate suspicious activity across domains. We discuss mitigation strategies like layered access zones, mantraps, environmental sensors, and proper training of on-site personnel. Physical security is often a prerequisite to cybersecurity—after all, if someone can walk into your server room unchecked, firewalls and encryption won’t save you. A holistic defense strategy begins with securing the doors.
