Best Practices: Inside-Out vs. Outside-In Security -- Blue Lance

Our bank is evaluating different technology approaches in an effort to better protect ourselves against computer-related theft and fraud. We have heard that external threats now outnumber internal threats. Is that true or do we still need to worry about insiders?

The Computer Security Institute and the FBI publish an annual survey which covers security trends, including threats. This year, they announced that external attacks are outnumbering internal attacks. While this is true, statistics still show that internal threats account for a large percentageof the DOLLARS lost to computer crimes. And Gartner research analysts predict that with increased access to internal networks through e-commerce activities, partners, contractors and vendors, the insider/outsider loss ratio is actually heading towards 90:10. Therefore, it is still critical to monitor activity closest to the assets you're trying to protect...inside the firewall.

For further insight into this issue, I would suggest you read the white paper entitled "Protecting Computer-Managed Assets: Building a Secure Infrastructure for Business".<
