Performance Statistics
Enable onClick="enable_change(false)"> Performance Statistics for this interface.
HTTP Inspect Settings
Enable onClick="enable_change(false)"> Use HTTP Inspect to Normalize/Decode and detect HTTP traffic and protocol anomalies.
HTTP server flow depth
-1 to 1460 (-1 disables HTTP inspect, 0 enables all HTTP inspect)
Amount of HTTP server response payload to inspect. Snort's performance may increase by adjusting this value.
Setting this value too low may cause false negatives. Values above 0 are specified in bytes. Default value is 0
Stream5 Settings
Max Queued Bytes
Minimum is 1024, Maximum is 1073741824 ( default value is 1048576, 0 means Maximum )
The number of bytes to be queued for reassembly for TCP sessions in memory. Default value is 1048576
Max Queued Segs
Minimum is 2, Maximum is 1073741824 ( default value is 2621, 0 means Maximum )
The number of segments to be queued for reassembly for TCP sessions in memory. Default value is 2621
General Preprocessor Settings
Enable
RPC Decode and Back Orifice detector		 onClick="enable_change(false)">
Normalize/Decode RPC traffic and detects Back Orifice traffic on the network.
Enable
FTP and Telnet Normalizer		 onClick="enable_change(false)">
Normalize/Decode FTP and Telnet traffic and protocol anomalies.
Enable
SMTP Normalizer		 onClick="enable_change(false)">
Normalize/Decode SMTP protocol for enforcement and buffer overflows.
Enable
Portscan Detection		 onClick="enable_change(false)">
Detects various types of portscans and portsweeps.
Enable
DCE/RPC2 Detection		 onClick="enable_change(false)">
The DCE/RPC preprocessor detects and decodes SMB and DCE/RPC traffic.
Enable
DNS Detection		 onClick="enable_change(false)">
The DNS preprocessor decodes DNS Response traffic and detects some vulnerabilities.
Define SSL_IGNORE
Encrypted traffic should be ignored by Snort for both performance reasons and to reduce false positives.
Default: "443 465 563 636 989 990 992 993 994 995". Please use spaces and not commas.
