Ensure Compliance with ASD Communication Security Policies
Follow ASD's security rules for operating and managing communication systems safely.
Plain language
This control is about following specific security guidelines set by the Australian Signals Directorate (ASD) when managing communication systems. It's important because if these rules aren't followed, sensitive information could be intercepted or tampered with, leading to serious privacy breaches and potential financial losses.

Communications security doctrine and policy produced by ASD for the management and operation of HACE is complied with.
Why it matters
Without complying with ASD HACE communications security policy, interception or compromise of sensitive communications may occur, leading to privacy breaches and legal consequences.
Operational notes
Review ASD HACE communications security policies regularly, and update procedures and configurations promptly when ASD doctrine or policy changes.
Implementation tips
- The IT manager should ensure all staff managing communications systems are familiar with the ASD's security policies. This can be done by organising regular training sessions where the staff learn about these policies and their importance.
- System administrators should regularly review and update communication systems to ensure they comply with ASD guidelines. They can do this by conducting monthly checks and logging any changes made to keep systems secure.
- The compliance officer should create a checklist based on ASD policies to help the team consistently apply the required rules. This checklist should be used during system audits and updates to ensure nothing is overlooked.
- Managers should encourage their teams to report any issues or uncertainties regarding the security of communication systems promptly. They can set up a straightforward reporting process, such as an email hotline where staff can ask questions.
- Human Resources should include cybersecurity responsibilities in job descriptions for roles involving communication systems management. This ensures that new hires understand their role in maintaining security from day one.
