Study: Surveillance Messages Reduce Chances of Computer Command Entries into Hacked Systems by 8%

cybersecurityA study by the National Consortium for the Study of Terrorism and Responses to Terrorism says the presence of a surveillance banner on a hacked computer network reduces the chances of system intruders to input commands into the network by 8 percent.

Nearly 50 percent of hackers that did not encounter surveillance banners and failed to enter commands into the system during the first intrusion were able to input additional commands during the second trespassing attempt compared with 38 percent of those who encountered surveillance messages, START said in a July report.

START is a research center headquartered at the University of Maryland and established by the Department of Homeland Security as part of the science and technology directorate.

The National Science Foundation-funded study also found no significant difference in the number of network intrusions between compromised systems with surveillance messages and those without the banners.

“While the employed surveillance banner did not reduce the total number of trespassing incidents, it did affect the likelihood of an intruder escalating their offending by typing into the system on the first and second trespassing incidents,” lead project researcher Theodore Wilson wrote.

“Future research should employ and test both stronger messages as well as more active forms of surveillance on compromised systems,” he added.
