Virtualization presents security and cost risks
Friday, August 8, 2008
Businesses have been urged by network security analysts to be aware that virtualization strategies could end up costing more than traditional architecture and expose them to greater risks.
Commenting at the Black Hat conference, IT security researcher Christopher Hoff, said that virtualization can have a serious impact on system resilience, scalability and performance.
He insisted that the current rush towards virtualized networks is creating an increasingly messy security situation, Networkworld.com reported.
Mr Hoff claimed: "[With virtualization,] you won't get rid of host-based security software. As we add more solutions, we add complexity."
Meanwhile, fellow network security researcher Joanna Rutkowska explained that full disclosure could lead to an increased proliferation of rootkit exploits.
Other recent developments at the Black Hat conference included the assertion by Dan Kaminsky that the much publicised domain name service flaw could affect email security as well.
According to the Associated Press, he told delegates that the bug could allow hackers to intercept emails silently while they are in transit.
