I was going to open a post for the IPS, but finding this discussion answered my questions. To give everyone an idea on what is causing our issue, it's a flood of "denied tcp" attempts on ports 135, 139 and 445 that are hitting the ASA about 4-7 times a second. So it looks like the answer to my question is yes it probably is associated to the same events. I've now seen this alert three times while writing this post and keeping an eye on the ASA and IPS. Originally I started looking at the IPS only then I thought I would time my review of the ASA logs to see if anything occurred at the same time. The green Memory and Disk Usage percentage bars would go blank for about a minute. Would this issue affect an IPS-20 module that is active in the ASA "5510"? I was trying to figure out why our IPS, or more specifically the Cisco IPS Manager Express "IME" "Memory & Load" gadget was acting funny on the IME dashboard. Note: If you do not want the drop rate exceed warning to appear, you can disable it by running the no threat-detection basic-threat command. Adjust the threshold rate of the particular drop to an appropriate value by running the threat-detection rate bad-packet-drop command. If the object in the syslog message is a TCP or UDP port, an IP protocol, or a host drop, check whether the drop rate is acceptable for the running environment.Ĥ. Adjust the threshold rate of the particular drop to an appropriate value by running the threat-detection rate xxx command, where xxx is one of the following:ģ. If the object in the syslog message is one of the following:Ĭheck whether the drop rate is acceptable for the running environment.Ģ. Recommended Action Perform the following steps according to the specified object type that appears in the message:ġ. Current burst rate is 0 per second, max configured rate is 400 Current average rate is 760 per second, max configured rate is 100 Cumulative total count is 1938933" Current burst rate is 10 per second_max configured rate is 10 Current average rate is 245 per second_max configured rate is 5 Cumulative total count is 147409 (35 instances received)įor bad packets due to potential attacks: Current burst rate is 1 per second, max configured rate is 8000 Current average rate is 2030 per second, max configured rate is 2000 Cumulative total count is 3930654."įor a scanning drop due to potential attacks: The following three examples show how these variables occur:įor an interface drop due to a CPU or bus limitation: total_cnt-The total count since the object was created or cleared.Most objects can be configured with up to three different rates for different intervals. rate_ID-The configured rate that is being exceeded.For example, you might see "80/HTTP" that would signify port 80, with well-known protocol HTTP.) (A citation of a particular interface object might take a number of forms. Object-The general or particular source of a drop rate count, which might include the following:.It indicates the system is under potential attack. The object can be drop activity of a host, TCP/UDP port, IP protocol, or various drops due to potential attacks.
