2.3: Independent review of information and network security

Oh no! No description found. But not to worry. Read from Tasks below how to advance this topic.

1. The relevant entities shall review independently their approach to managing network and information system security and its implementation including people, processes and technologies.

2. The relevant entities shall develop and maintain processes to conduct independent reviews which shall be carried out by individuals with appropriate audit competence. Where the independent review is conducted by staff members of the relevant entity, the persons conducting the reviews shall not be in the line of authority of the personnel of the area under review. If the size of the relevant entities does not allow such separation of line of authority, the relevant entities shall put in place alternative measures to guarantee the impartiality of the reviews.

3. The results of the independent reviews, including the results from the compliance monitoring pursuant to point 2.2 and the monitoring and measurement pursuant to point 7, shall be reported to the management bodies. Corrective actions shall be taken or residual risk accepted according to the relevant entities’ risk acceptance criteria.

4. The independent reviews shall take place at planned intervals and when significant incidents or significant changes to operations or risks occur.

The ISMS component hierachy

When building an ISMS, it's important to understand the different levels of information hierarchy. Here's how Cyberday is structured.

Framework

Sets the overall compliance standard or regulation your organization needs to follow.

Requirements

Break down the framework into specific obligations that must be met.

Tasks

Concrete actions and activities your team carries out to satisfy each requirement.

Policies

Documented rules and practices that are created and maintained as a result of completing tasks.

Never duplicate effort. Do it once - improve compliance across frameworks.

Reach multi-framework compliance in the simplest possible way
Security frameworks tend to share the same core requirements - like risk management, backup, malware, personnel awareness or access management.
Cyberday maps all frameworks’ requirements into shared tasks - one single plan that improves all frameworks’ compliance.
Do it once - we automatically apply it to all current and future frameworks.
