Simon,

Shunning is feature for the Netranger sensor to automatically log into the
configured routers and place a dynamic ACLs when packets match a certain
signature (u can configure which signature). This will result in blocking
the source of the packets.

This dynamic ACLs will remain to a certain time periods that u can configure
it say for example one hour, then after the ACL will be removed by the
sensor that is managing that router. If attack is still in progress the
sensor will place these ACLs again.

Just be careful when using this feature to select only the signatures that u
really want them to be blocked when hit your router, otherwise u may block
necessary legitimate traffic for your corporate.

Best Regards

Ohanes Semerjian

Thanks.
