Physical security involves measures taken to protect physical assets, such as buildings, equipment, and people, from unauthorized access or harm. For example, installing security cameras and alarm systems, restricting access to certain areas with key cards or biometric scanners, and having security guards patrol premises are all examples of physical security measures.

Cybersecurity, on the other hand, focuses on protecting digital assets, such as data, networks, and systems, from cyber threats like hacking, malware, and phishing attacks. Implementing firewalls, encryption, and multi-factor authentication, regularly updating software, and conducting security audits are common cybersecurity practices.

When both physical and cyber security measures are combined, an organization can create a comprehensive security strategy that safeguards both its physical and digital assets effectively. For instance, a company may have surveillance cameras monitoring its premises while also having strong network security measures in place to prevent unauthorized access to its systems and data.
