2.3.3: Deactivate unnecessary functionality

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

Deactivate unnecessary functionality. Consider deactivating built-in functions (in both operating systems and applications) on clients, servers and network equipment not needed by the organisation in order to reduce the attack surface. This could include i) older or unused protocols, ii) built-in support for personal cloud services, for example, iii) other built-in services that the organisation will not be using.

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.
