Security refers to the measures and practices implemented to protect people, property, assets, and information from threats, harm, or unauthorized access. It is a fundamental component of personal, corporate, industrial, and public safety. Security aims to prevent incidents such as theft, vandalism, violence, cyberattacks, or sabotage, while ensuring continuity of operations and maintaining a safe environment for all stakeholders.

• Information Security: Safeguards sensitive data and intellectual property against cyber threats.

• Event and Crowd Security: Manages large gatherings, nightlife venues, and public events to prevent conflicts and ensure safety.
