OK, I’m sold what should I do? • Start with the Board of Directors • Does the Board take an interest in IT security? • Does the Board ask senor management the tough questions about IT security? • Does the Board know what to ask? • Same questions for the CEO and CFO. bnearon@jhcohn.com 973-403-6955
The Tough Questions • Has the company done an IT security risk assessment? • How does senior management know that the network is secure? • Has the Board communicated their expectations regarding security? • What level of security is expected? • Has there been an assessment of IT security done independent of the IT department? bnearon@jhcohn.com 973-403-6955
Organizational Red Flags • Does the CIO report to the CFO? • Is there an IT steering committee made up of senior management? • What is senior management’s philosophy regarding IT security? • Is IT security left up to the IT department? bnearon@jhcohn.com 973-403-6955
More Red Flags • Are there written IT security policies and procedures? • Has the company adopted a System Development Life Cycle (SDLC) standard? • Does the CFO know which users can change financial data? • Are audit logs enabled, reviewed, and retained? • Does someone independent of IT review the logs? bnearon@jhcohn.com 973-403-6955
More Red Flags • How many people in the IT department have ADMIN, ROOT, ALL OBJECT, or SUPERUSER rights? • Is there an up-to-date IT asset inventory list? bnearon@jhcohn.com 973-403-6955
Wrap-up • Security –Today’s systems were never designed to be secure. • You have to secure them yourself. • The key to security is the Board and senior management understanding security, taking responsibility for it, and communicating their expectations. bnearon@jhcohn.com 973-403-6955
