Conclusion: Does IT Security Matter? • IT Security in general is not an end in itself • IT Security is one area competing for attention and funding, amongst many • If you don’t make IT security matter, it won’t • Keeping business secure is the main end • Focus on securing business processes not the process of securing • Excel is your new best friend • Make your spreadsheets work with their spreadsheets • A risk-based approach is the opportunity to speak business language • Don’t replace FUD with GIGO (garbage in, garbage out)
