On the morning of 18 September 2014, police in Australia carried out the biggest counter-terrorism operation in the nation's history, with over 800 heavily armed officers targeting households in the cities of Sydney and Brisbane.
 It came days after the Australian government raised the terror threat from medium to high due to concerns about Australian citizens returning to the country after fighting with the Islamic State of Iraq and the Levant (ISIL).
 Following the raids, two people were charged, one with terrorism offences and the other for possession of an unauthorised firearm.

"Domain Based Security", abbreviated to "DBSy", is a model-based approach to help analyse information security risks in a business context and provide a clear and direct mapping between the risks and the security controls needed to manage them.
 A variant of the approach is used by the UK government's HMG Infosec Standard No.1 technical risk assessment method.

Supermax (short for: super-maximum security) is the name used to describe "control-unit" prisons, or units within prisons, which represent the most secure levels of custody in the prison systems of certain countries.
 The objective is to provide long-term, segregated housing for inmates classified as the highest security risks in the prison system—the "worst of the worst" criminals—and those who pose a threat to both national and global security.
Taint checking is a feature in some computer programming languages, such as Perl and Ruby, designed to increase security by preventing malicious users from executing commands on a host computer.
 Taint checks highlight specific security risks primarily associated with web sites which are attacked using techniques such as SQL injection or buffer overflow attack approaches.
The High Risk Management Centre (commonly called the SuperMax) was opened in September 2001.
 This was the first such facility in Australia and makes the Centre the highest security prison in Australia.
