Oh no! No description found. But not to worry. Read from Tasks below how to advance this topic.
MIL1 requirements
a. Network protections are implemented, at least in an ad hoc manner
b. The organization’s IT systems are separated from OT systems through segmentation, either through physical means or logical means, at least in an ad hoc manner
MIL2 requirements
c. Network protections are defined and enforced for selected asset types according to asset risk and priority (for example, internal assets, perimeter assets, assets connected to the organization’s Wi-Fi, cloud assets, remote access, and externally owned devices)
d. Assets that are important to the delivery of the function are logically or physically segmented into distinct security zones based on asset cybersecurity requirements
e. Network protections incorporate the principles of least privilege and least functionality
f. Network protections include monitoring, analysis, and control of network traffic for selected security zones (for example, firewalls, allowlisting, intrusion detection and prevention systems (IDPS))
g. Web traffic and email are monitored, analyzed, and controlled (for example, malicious link blocking, suspicious download blocking, email authentication techniques, IP address blocking)
MIL3 requirements
h. All assets are segmented into distinct security zones based on cybersecurity requirements
i. Separate networks are implemented, where warranted, that logically or physically segment assets into security zones with independent authentication
j. OT systems are operationally independent from IT systems so that OT operations can be sustained during an outage of IT systems
k. Device connections to the network are controlled to ensure that only authorized devices can connect (for example, network access control (NAC))
l. The cybersecurity architecture enables the isolation of compromised assets

In Cyberday, requirements and controls are mapped to universal tasks. A set of tasks in the same topic create a Policy, such as this one.
In Cyberday, requirements and controls are mapped to universal tasks. Each requirement is fulfilled with one or multiple tasks.
When building an ISMS, it's important to understand the different levels of information hierarchy. Here's how Cyberday is structured.
Sets the overall compliance standard or regulation your organization needs to follow.

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

Concrete actions and activities your team carries out to satisfy each requirement.
Documented rules and practices that are created and maintained as a result of completing tasks.
