What are the different levels of IRAP assessment?

The Information Security Manual (ISM) of the Australian Signals Directorate (ASD) outlines four levels of data classification requirements: UNCLASSIFIED, PROTECTED, SECRET, and TOP SECRET. In addition to these, the ASD also provides four levels of Information Security Risk Assessment and Authorization (IRAP) assessment, which is used to determine the security controls needed to protect information assets. The four levels of IRAP assessment are: 1. Basic: This is the most basic level of assessment, which is suitable for low-risk information assets. This level of assessment is typically used for assets with a low level of sensitivity and can be conducted without the need for a formal risk assessment. 2. Standard: This level of assessment is suitable for medium-risk information assets, such as those with a moderate level of sensitivity. It includes a more detailed risk assessment and the determination of appropriate security controls. 3. Enhanced: This level of assessment is suitable for high-risk information assets, such as those with a high level of sensitivity. It includes a comprehensive risk assessment and the determination of appropriate security controls. 4. Comprehensive: This is the highest level of assessment, which is suitable for very high-risk information assets, such as those with a very high level of sensitivity. It includes a comprehensive risk assessment and the determination of appropriate security controls. In order to determine which level of assessment is appropriate for a given information asset, the ASD recommends the use of the Information Security Risk Assessment and Authorization (IRAP) framework. This framework is based on the ASD’s Risk Management Framework and requires the assessment of the risk associated with the information asset, the sensitivity of the information, and the impact of a security breach. The IRAP assessment process includes the identification of threats, vulnerabilities, and impacts, as well as the determination of appropriate security controls. The security controls should be tailored to the specific needs of the information asset and should be based on the risk assessment. Once the appropriate security controls have been determined, the ASD recommends that the security controls be tested and monitored to ensure that they are effective at protecting the information asset. The ASD also recommends that the security controls be regularly reviewed and updated as necessary. In summary, the ASD provides four levels of Information Security Risk Assessment and Authorization (IRAP) assessment, which are used to determine the security controls needed to protect information assets. The four levels of assessment are Basic, Standard, Enhanced, and Comprehensive, and they are based on the ASD’s Risk Management Framework. The security controls should be tailored to the specific needs of the information asset and should be tested and monitored to ensure that they are effective. .
