cyber security short course - Security Controls: Technical, Physical & Administrative Layers

Understanding the different types of security controls is essential for building a strong cybersecurity foundation. In this video, we break down the three core categories of security controls Technical, Physical, and Administrative—and explain how each one plays a crucial role in protecting systems, data, and people. Technical Controls are the technology-driven measures that shield digital environments from threats. These include firewalls, antivirus software, encryption, intrusion detection systems, and access control mechanisms. Their job is to prevent, detect, and respond to cyberattacks in real time. Physical Controls focus on protecting the physical environment. This includes everything from door locks, keycards, and security guards to CCTV cameras and secure server rooms. These controls help prevent unauthorized individuals from gaining physical access to critical systems. Administrative Controls form the policy and people-focused side of security. They include security policies, staff training, incident response procedures, risk assessments, and guidelines that shape how an organization operates securely. When these three control types are combined, they create a powerful layered defense strategy. Effective cybersecurity doesn’t rely on one control alone—it's the synergy between technical, physical, and administrative controls that strengthens an organization’s security posture and helps address a wide range of risks and vulnerabilities. #cybersecurity
