ASD Essential 8: Application whitelisting

Application whitelisting is an important tool for organizations to utilize in order to protect their systems from malicious software, such as malware, ransomware, and other cyber threats. The Australian Signals Directorate (ASD) Essential 8 is a set of eight security strategies which organizations should use to protect their systems from cyber threats. Application whitelisting is one of the eight strategies, and is used as a way to block any unauthorized applications from running on a system. Application whitelisting works by blocking all applications except for those which have been specifically approved by an IT administrator. This process is usually done through the use of a whitelist, which is a list of approved applications that can be run on the system. Any applications that are not on the whitelist are automatically blocked. This ensures that only applications which have been reviewed and approved by an IT administrator can be run on the system, thus providing an additional layer of security. The process of whitelisting applications can be time consuming, as the IT administrator must review each application and approve or deny them. This process also requires a deep understanding of the application and its functionality, as well as any potential security risks that may arise from running it. The IT administrator must also ensure that the application is kept up to date and any security vulnerabilities are patched. In addition to the time consuming process of whitelisting applications, there are also a few other drawbacks to the process. For example, whitelisting can be difficult to maintain as applications are updated or new ones are added. Additionally, the process of whitelisting can be bypassed if an attacker is able to gain access to the system and modify the whitelist. Despite these drawbacks, application whitelisting is still an important tool for organizations to utilize in order to protect their systems from malicious software. By using a whitelist, organizations can ensure that only approved applications are allowed to run on their systems, thus reducing the risk of malicious software being injected. Additionally, by keeping the whitelist up to date, organizations can ensure that any security vulnerabilities are patched and the system remains secure. In conclusion, application whitelisting is an important tool for organizations to utilize in order to protect their systems from malicious software. By using a whitelist, organizations can ensure that only approved applications are allowed to run on their systems, thus reducing the risk of malicious software being injected. Additionally, by keeping the whitelist up to date, organizations can ensure that any security vulnerabilities are patched and the system remains secure. By following the ASD Essential 8, organizations can ensure that their systems are protected from cyber threats. .
