Liability limited by a scheme approved under Professional Standards Legislation EY’s Global Information Security Survey: It is no longer possible to prevent attacks or breaches ► Cybercrime is growing and damages an organisation and its brands ► The interconnectivity of people, devices and organizations opens up new vulnerabilities. ► New technologies, regulatory pressure and changing business requirements call for more security measures. ► What companies used to know and do to protect their information is no longer enoughenough. ► No longer just “an IT Problem”; Cybersecurity is a genuine business issue that has ramifications for the C-suite, Board, Directors ► The wrong question to ask is “Are we secure”; (because the answer is “No”) ► Mature organisations ask “are we doing enough to protect ourselves from cybercrime?”; how good is good enough? What data do you collect, store or generate that a cybercriminal would be most interested in? When and how would you identify a sophisticated attack – and how would you respond? 12 Copyright © 2017 Ernst & Young Australia. All Rights Reserved.

Social engineering is the art of manipulating people so they give up confidential information. The types of information these criminals are seeking can vary, but when individuals are targeted the criminals are usually trying to trick you into giving them your passwords or bank information, or access your computer to secretly install malicious software – that will give them access to your passwords and bank information as well as giving them control over your computer. 18 Copyright © 2017 Ernst & Young Australia.

Page 22 Limit the damage when cyber incidents occur Poor handling of cyber incidents (internally and externally) have led to harsh impacts on many companies. ► A centralised, enterprise-wide cyber breach responseresponse plan is vital ► Be confident that everyone knows exactly what to do if an attack takes place ► Be ready to set in motion the appropriate handling mechanisms for a breach ► Forensic handing of data and systems ► Consider stakeholders, customers, employees, PR, regulators, etc. ► Being in a state of readiness requires that the organisation will have already rehearsed many different attack scenarios ► Introduce board-level cybersecurity simulations and war gaming ► Regularly undertake cybercrime diagnostic assessments/reviews Page 23 The basics….. 1. Ensure vulnerability and patch management policies and procedures are up to date 2. Incident response and business continuity plan that is tested 3. Security awareness training program in place 4. Regular, tested backups are in place 5. Seek assurance from third parties who connect to your network 6. Implement endpoint monitoring 7. Identify critical systems and data and confirm these are connected to the Internet only when necessary 8. Test the security program with frequent penetration tests Page 24 Page 25 “It is going to be a continual and likely never-ending battle to stay ahead of [cybercrime] - and, unfortunately, not every battle will be won .” Jamie Dimon, after JP Morgan 26 Chase’s breach EYEYEY | Assurance | Tax | Transactions | Advisory About EY EY is a global leader in assurance, tax, transaction and advisory services.
