Guidelines and Limitations
This section includes the guidelines and limitations for this feature:
Security Context Guidelines
Supported in single mode only. Multiple mode is not supported.
Firewall Mode Guidelines
Supported in routed and transparent firewall mode.
Types of Traffic Monitored
• Only through-the-box traffic is monitored; to-the-box traffic is not included in threat detection.
• Traffic that is denied by an access list does not trigger scanning threat detection; only traffic that is
allowed through the ASA and that creates a flow is affected by scanning threat detection.
Default Settings
Table 1-5 lists the default rate limits for scanning threat detection.
The burst rate is calculated as the average rate every N seconds, where N is the burst rate interval. The
burst rate interval is 1/30th of the rate interval or 10 seconds, whichever is larger.
