Security is defined as protection from, or resilience against, potential harm, unwanted coercion, or damage. It covers a wide range of fields, encompassing both physical safety and virtual protection for individuals, organizations, and assets. Core Types of Security
Physical Security: Protects people, buildings, and assets from physical harm or damage. Measures include surveillance cameras, access control systems, and security personnel.
Cybersecurity: Safeguards digital information, computer systems, and networks from cyber threats, attacks, and unauthorized access.
Information Security (InfoSec): Focuses on protecting data in all forms, ensuring confidentiality, integrity, and availability.
Personal Security: Ensures the safety and well-being of individuals, often focusing on protection from harassment or harm.

Encryption: Converting information into a code to prevent unauthorized access, particularly crucial for data storage and transmission.
Firewalls: Monitoring and controlling network traffic to prevent cyberattacks.
Patch Management: Regularly updating systems and software to fix vulnerabilities.
Surveillance: Utilizing cameras and monitoring tools for situational awareness.
