Juniper Networks Assigned Patent for Moving Security for Virtual Machines

Juniper Networks, Sunnyvale, Calif., has been assigned a patent (8,261,317) developed by Moshe Litvin, Sunnyvale, Calif., and Gilad Benjamini, Davis, Calif., for a "moving security for virtual machines."

The abstract of the patent published by the U.S. Patent and Trademark Office states: "A method of maintaining multiple firewalls on multiple host nodes. Each host node runs one or more virtual machines. For at least a first host node, the method maintains multiple sets of policies for multiple virtual machines that run on the first host node. The method, upon detecting that a particular virtual machine has been moved from the first host node to a second host node, removes a set of policies associated with the particular virtual machine from the first host node and supplies the set of policies to the second host node."

The patent application was filed on Jan. 5, 2009 (12/348,898). The full-text of the patent can be found at http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-bool.html&r=1&f=G&l=50&co1=AND&d=PTXT&s1=8,261,317&OS=8,261,317&RS=8,261,317
