Introduction to Information Security Processes

Information security processes encompass a range of activities designed to safeguard information assets and are integral to the operational integrity and success of any business.

The Essence of Information Security Processes

Information security processes are structured actions and protocols implemented to prevent unauthorised access, use, disclosure, disruption, modification, or destruction of information. They form the backbone of an organisation’s security posture, ensuring the confidentiality, integrity, and availability of data.

Alignment with Organisational Goals

Information security processes must be in harmony with the organisation’s goals. They should support the business’s mission while protecting its most valuable assets: its data and information systems.

Intersection with Compliance

Compliance and regulatory requirements often dictate the structure and implementation of information security processes. Adhering to standards like ISO 27001 ensures that organisations not only protect their information but also meet legal and ethical obligations.
