Victim IPs

IP addresses of the most recent victims (up to 5 addresses).

Total Victim IP Count

Note

For most IPS ping sweep events, certain statistics are estimated values rather than exact counts. The following values are provided as reference information only:

  • Victim IP Count

  • Attacker IP Count

Analysis of ping sweep activity is a resource-intensive process. When it is necessary to conserve resources, the analysis process does not record all IP addresses involved in the ping sweep activity. In this case, the process must estimate the count of IP addresses or port numbers. To estimate the count, the process compares the current IP address or port count with the most recent IP addresses or port counts in cache memory.
