Communication security (COMSEC) safeguards reduce the threat of unauthorised people gaining access to your communications.
COMSEC includes cryptography, transmission security, emission security, traffic-flow security, and physical security of COMSEC equipment.
Your organisation should use mitigation strategies to reduce the threat of unauthorised access to communications. Encrypt all communications during transmission. You may need high-grade cryptographic equipment.
The standards relevant to these requirements are:
- New Zealand Communications Security Standard No. 300 (NZCSS 300). This standard provides the minimum security requirements for the control and accountability of communications security material within New Zealand Government and agencies.
- New Zealand Communications Security Standard No. 400 (NZCSS 400). This standard provides a minimum standard of installation engineering for all New Zealand Government agencies, organisations, or personnel concerned with the planning or engineering of New Zealand installations processing protectively-marked information.
- New Zealand Communications Security Standard No. 500 (NZCSS 500). This standard provides consolidated statements of national communications security policy. Where necessary, more information about the policy will be provided in the relevant national communications security standards or instructions.
