Information Security (InfoSec) is the practice of protecting information and data from unauthorized access, use, disclosure, disruption, modification, or destruction. It ensures the confidentiality, integrity, and availability (CIA) of data across all digital and physical forms.

With increasing cyber threats and regulatory requirements, Information Security is critical for organizations to protect sensitive business, customer, and employee data.


What Is Information Security?

Information Security focuses on safeguarding data from both internal and external threats. It involves implementing policies, processes, and technologies to prevent data breaches, maintain privacy, and ensure compliance with regulations.

Unlike cybersecurity, which broadly focuses on digital threats, InfoSec includes both digital and non-digital data protection measures.


Key Principles of Information Security

Confidentiality

Ensures that sensitive information is accessible only to authorized users.

Integrity

Guarantees that information is accurate, complete, and protected from unauthorized modification.

Availability

Ensures that information and systems are accessible to authorized users when needed.


Core Components of Information Security

Access Control

Regulates who can view or modify data through authentication and authorization mechanisms.

Data Encryption

Protects data at rest and in transit using strong encryption standards.

Security Policies & Procedures

Defines organizational rules and best practices for handling information securely.

Risk Management

Identifies potential threats, assesses risks, and implements controls to mitigate them.

Incident Response

Prepares organizations to detect, respond to, and recover from security incidents efficiently.
