Insider Breaches
If the name Timothy Lloyd
doesnt send shivers up your spine, it should. Timothy Lloyd is to
insider security as Kevin Mitnick is to social engineering and David
L. Smith is to viruses. In one of the costliest acts of insider
sabotage in recent memory, Lloyd was convicted in May of causing an
estimated $12 million in damages to Omega Engineering, his former
employer. Back in 1996, Lloyd found out he was about to be fired, so
he planted a logic bomb that systematically erased all of Omegas
contracts and the proprietary software used by the companys
manufacturing tools. Lloyds act of insider cyberterrorism cost
Omega its competitive position in the electronics manufacturing
market. At Lloyds trial, plant manager Jim Ferguson said, We will
never recover. .The Information Security survey confirms what
previous studies (including our own) have been saying for years: The
Timothy Lloyds of the world represent at least as much risk to
corporate assets as external crackers and virus writers. In many
ways, insiders present a far greater risk than outsiders do. Insider
cybercrime is harder to quantify and counteract. Its not purely a
bits and bytes problem, but one that involves human psychology and
complicated workplace dynamics. And the problem is getting worse,
not better. While the media tends to focus on sexy cyberattacks
such as denial-of-service, buffer overflows and Web defacements, the
frequency of these attacks pale by comparison to insider access
control breaches, software/hardware misuse and abuse of Internet use
privileges.
