Hackers can still exploit ‘flaws’ in security systems

Hackers pose a high risk for the majority of companies as firms have major vulnerabilities in their internet connections, a survey suggests. A report by NTA Monitor has discovered that 61% of companies have a ‘flaw’ in their internet systems, which would allow a hacker to gain control of their computers.

The vulnerability is widely known and understood by those wishing to gain unauthorised access and as a result is often exploited. Hackers who target the weakness are often able to launch ‘denial of service’ attacks, which shut business owners out of their own systems.

Roy Hills, technical director at NTA Monitor, said: “The majority of the high risk flaws found were service specific, relating to the services that were accessible within the gateways tested. Nine of the ten most commonly occurring high risk issues fell within this area, with the remaining issue being Internet router related.

“An attacker who was aware of the programs being used and their flaws could exploit those vulnerabilities to gain network access or launch a denial of service attack. Of the companies tested, 99% had one or more informational risks indicating that typically companies have poor security housekeeping policies or lack the knowledge of how some Internet mechanisms work.”
