Invitations to complete an ASX and ASIC backed cyber survey have been sent to Australia\u2019s 100 biggest companies today with an advisory note: don\u2019t let your CIO fill it in. The ASX 100 Cyber Health Check is a voluntary survey, promised in the government\u2019s $230m Cyber Security Strategy, to benchmark cyber security awareness, capability and preparedness in Australia top listed businesses. The opening question of the voluntary ASX 100 Cyber Health Check begins with \u201c\u2026we request that this questionnaire is not passed to the Chief Information Officer or others to complete on your behalf\u2026\u201d \u201cWe advise against the CIO or any other representative of the organisation completing the questionnaire,\u201d reads the survey\u2019s FAQs in answer to the question: Would my CIO be the best person to undertake this? Due to the governance angle of the survey, its completion instructions urge that it is filled in only by \u201cthe Chairman, the Audit Committee Chair or the Risk Committee Chair\u201d. A CIO may \u201cmiss a governance link, which exacerbates a specific vulnerability\u201d the advice reads. A better informed board The survey\u2019s aim is to build a picture of cyber security awareness and risk appetite at the board or committee chair level. \u201cThe intent of the 2016 Cyber Health Check is to raise awareness of cyber security at the Board level and share best practice approaches so that boards are more informed as they assess their own security capabilities and plans,\u201d the document explains. \u201cCyber security is a strategic risk management issue for the Board, not one to be left solely to the IT Department.\u201d Questions cover how regularly the board receives \u201cregular high level intelligence from the CIO\u201d about what cyber actors are targeting the company, and the level of understanding among directors around the cyber security capabilities of vendors and suppliers. Responses are anonymous and a public report on the themes emerging from the data is expected to be released in March next year. \u201cThe better informed boards become, the more effectively they can assess their cyber security risks and opportunities, including identifying areas where improvement is required. Participation will reassure shareholders and the broader community that boards are actively engaged in addressing cyber issues,\u201d said Amanda Harkness, ASX Group Executive, on the survey\u2019s launch. \u201cThe results will help businesses improve their cyber security which is positive for employees, shareholders and the economy. The lessons learnt as part of this initiative will be used to identify and develop cyber security best practice that can be applied across the broader Australian business community,\u201d said the Minister Assisting the Prime Minister on Cyber Security, Dan Tehan. In its Cyber Security Strategy, the government said that eventually, similar health checks would be available for public and private organisations, tailored to size and sector. The ASX 100 Cyber Health Check was developed by the Australian Securities Exchange, with the Australian Securities and Investments Commission, the Attorney-General\u2019s Department and Australia\u2019s largest four auditing firms KPMG, PwC, Deloitte and EY.
