Physical cybersecurity attacks explained for the CPA exam — this lecture covers the physical attacks that target an organization's premises and hardware directly, distinct from remote network exploits, a key topic on the Information Systems and Controls (ISC) CPA exam. Designed for accounting practitioners and CPA, CMA, and EA candidates studying IT risks and controls, this session explains dumpster diving, lockpicking, USB drops, discarded equipment interception, piggybacking, tailgating, and tampering, along with practical mitigation strategies.

Frequently Asked Questions:

What is a physical cybersecurity attack?

A physical cybersecurity attack involves direct physical interaction with an organization's premises or hardware to steal, damage, or compromise systems. Unlike network-based attacks that happen remotely, these require the attacker to be physically present or to exploit physical access.

What is dumpster diving in cybersecurity?

Dumpster diving is the practice of searching an organization's trash for sensitive documents, such as records containing names, employee numbers, or account details. Attackers use this recovered information to facilitate further infiltration, which is why secure document destruction is important.

What is the difference between piggybacking and tailgating?

Both involve gaining access by exploiting an authorized person. Tailgating typically means slipping through a secure door behind someone with legitimate access, while piggybacking can also include using an unattended, logged-in device. Mantraps, security training, and automatic log-off policies help mitigate both.

How can organizations defend against physical cybersecurity attacks?

Defenses include strong physical access controls, surveillance, mantraps, security awareness training, and automatic log-off policies. For discarded equipment, organizations should use secure data erasure, physical destruction such as shredding, and professional disposal services.
