Physical Security
Physical security refers to the protection of people, hardware, software, networks, and data from physical actions and events that could cause serious loss or damage to an organization. It involves measures such as access control, surveillance, and environmental controls to prevent unauthorized access, theft, vandalism, or natural disasters. This concept is fundamental in cybersecurity, IT infrastructure, and facility management to ensure overall security posture.
Developers should understand physical security when designing systems that handle sensitive data, operate critical infrastructure, or require compliance with regulations like HIPAA or GDPR. It's essential for roles in DevOps, site reliability engineering (SRE), or any position involving on-premises servers, data centers, or IoT devices to mitigate risks from physical breaches. Learning this helps in creating holistic security strategies that integrate both digital and physical defenses.
