Latest Release Date:2003 August 01
Default Enabled:True
Default Retired:False
CVE:CVE-2000-0305

Description

Triggers when a datagram can not be fully reassembled due to missing data. This may indicate a denial of service attack or an attempt to defeat packet filter security policies.

Recommended Filter

No recommended filters.

Benign Triggers

Some fragmentation may occur normally in network traffic. Additionally, some fragments may be dropped enroute to their destination causing the data to be eventually resent. Fragmented traffic is in itself unusual, but a large number of incomplete datagrams is not expected and is most probably an active attack.
