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.

Financial Security: Protects financial assets and transactions from fraud or loss.

Access Control: Limiting access to authorized individuals only.

Authentication & MFA: Utilizing strong authentication methods (something you know, have, or are) and multi-factor authentication (MFA) to verify identity.

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.
