Protective Security Risk Reviews

These involve a comprehensive review of security threats and the development of recommended protective security measures, using risk-based methodology. ASIO-T4 has direct access to threat-based risk information in the risk review process, so as to assess all known potential sources of security risks. Recommendations will typically include physical, electronic, administrative, and procedural security measures to manage the risk.

Protective Security Advice

ASIO-T4 provides an ongoing specific advisory service for Government clients, on how best to protect their people, information and physical assets. This advice is tailored to address individual and specific requirements.

Advice may include perimeter security, access control measures, CCTV, alarm systems, locks and other door hardware, advice on the construction of new buildings, security zone construction, guarding arrangements, security audits and administrative and personnel security.

Certification of Zone 5 Facilities

ASIO-T4 is the certification authority, nominated in the Australian Government PSPF, for the physical security certification of all facilities/zones where the compromise, loss of integrity or unavailability of the information would have a catastrophic business impact level. This includes facilities/zones holding and/or discussing Top Secret security classified information and facilities/zones that have a large aggregation of information at lower classifications. Re-certification is required at least every five years. Early consultation with ASIO-T4 is recommended to ensure new facilities have the appropriate level of security built in from the design stage.

Physical Security Certification of Outsourced ICT Facilities

ASIO-T4 is responsible for certifying the physical security of Australian Signals Directorate Certified Gateway Service Provider facilities, intended for use by multiple Australian Government agencies as listed in the Business, Procurement and Asset Management Group, Department of Finance and Deregulation, Internet Gateway Reduction Program.

Technical Surveillance Counter Measures (TSCM)

ASIO-T4 offers technical surveillance countermeasures (TSCM) assistance to Australian Government departments and agencies to provide a level of assurance that highly classified or sensitive discussions and information are not subject to compromise through technical means – for example, through covert listening devices.

TSCM inspections are an important element of an appropriate protective security environment and must be supported by physical and procedural measures to ensure the integrity of an inspected area is maintained.

ASIO-T4 Approved Destruction Services

External destruction services are evaluated against T4 criteria to perform offsite destruction of sensitive and security classified information using approved equipment.
