ASD ISM 0626 Implementing CDS for secure network segmentation

IT Managers should identify which networks within your organisation need higher security due to sensitive information they handle.

You can do this by reviewing the types of data each network manages and consulting with your security officer.

IT Teams should implement Cross Domain Solutions, which act like secure gates, between networks dealing with top secret data and other networks.

This can involve installing specialised systems that ensure only safe and authorised information is shared.

Security Officers should regularly review and update protocols for data exchange between different network domains.

This means setting clear rules on what kind of information can be shared and verifying that these rules are being followed.

System Administrators should maintain and monitor logs of all data transactions passing through these secure gateways.

Use security tools to help track and flag any unusual activity, ensuring any suspicious behaviour is immediately addressed.

Policy Makers should ensure that comprehensive training programs are in place for staff who interact with secure networks.

This training should include understanding the importance of handling sensitive information and the steps required to maintain system integrity.
