DNS servers vulnerable

One in four DNS servers do not perform source port randomisation, according to a study conducted by Infoblox, a networking appliance vendor, and the Measurement Factory, a performance-testing and protocol-compliance consultancy, reports Information Week.

Security researchers say DNS will remain a primary exploit target because many people don't understand the Internet's domain name system.

DNS cache poisoning can lead to the hijacking of Internet traffic. The study also found more than 40% of Internet name servers still allow recursive queries, and 30% of DNS servers allow zone transfers to arbitrary requesters.

Scalent Systems, a provider in real-time management and automation software for virtual and physical infrastructure, says Blackboard Managed Hosting has implemented Scalent virtual operating environment software to control and enable Blackboard's cloud computing, states Market Watch.

Scalent virtual operating environment software enables Blackboard to deploy, change capacity or recover full system environments in minutes, improving efficiency and asset utilisation while maintaining reliability and reducing overall costs.

Blackboard had previously faced escalating expansion and reaction-time challenges driven by the increased pace of business change, statically allocated server hardware, and mixed physical and virtual environments.
