Alastair MacGibbon, the head of the Australian Cyber Security Centre (ACSC), has tendered his resignation and will return to the private sector. He also held the title of National Cyber Security Adviser at the Department of Home Affairs (DHA), where he was charged with the implementation of government's Cyber Security Strategy. He is indeed the face of cyber security in Australia and, through his leadership, helped raise the nation's cyber security standards," Burgess said. He also oversaw the completion of the network of Joint Cyber Security Centres (JCSC) for coordination with the private sector, a reshaping of the government's Information Security Manual (ISM), and a tightening of access controls for government systems as part of a new Essential Eight Maturity Model. Prior to his ACSC role, MacGibbon was then-Prime Minister Malcolm Turnbull's Special Adviser on Cyber Security, during which he led an investigation into the debacle that was the the 2016 Census. Australia's cybersecurity agency joins the nation's peak body for cyber professionals to deliver development programs through the government's Joint Cyber Security Centres.
