Experts at CY4OR, based in Bury, England, praised CSI for
bringing computer forensics to the forefront of public awareness;
but they say it does little to reflect the correct and essential
procedures that must be put in place when there is suspicion of
criminal activity.
In the offending episode, chemistry boffin Greg Sanders (played
by Eric Szmanda) walks on to a crime scene, turns on a nearby
computer and begins accessing email. Bad move, says Joel Tobias,
Managing Director of CY4OR. This is exactly what budding
investigators must not do, he warns.
"Not only could this potentially damage evidence, any
incriminating data that was uncovered would undoubtedly be thrown
out of a court of law as the proper evidential procedures would not
have been put in place," he said. "The evidential continuity would
have been compromised and a criminal case could collapse."
The temptation for IT departments to become digital detectives
and deal with a breach of security in house is understandable, says
Tobias, as companies worry about investor confidence, company
reputation and business in general. It can also be fun. However,
there are a few basic steps to follow, to minimise exposure and
resolve the situation as quickly as possible.
CY4OR's guide to crime scene investigations
- Treat the matter seriously. Tell your legal team not your
colleagues about your suspicions.
- Do not inform your IT department. Instead, hire computer
forensic experts (such as CY4OR).
Professional analysts from reputable companies adhere to ACPO
(Association of Chief Police Officer) guidelines, can identify
digital evidence quickly and ensure that it will stand up in court
by following the correct procedures. They can even image your
computers at night, to avoid inevitable discussions by the water
cooler.
The principal of forensics which says that ‘every contact leaves
a trace’ cannot be emphasised enough, says Tobias. "There is a time
and a place to leave it to the experts, and this is it," he
warned.
