WEBROOT-DIRECTORY-

TRAVERSAL ATTACK

This is when a directory traversal traverses past the web 

server root directory. This generates much fewer false 

positives than the directory option, because it doesn’t alert 

on directory traversals that stay within the web server 

directory structure. It only alerts when the directory 

traversals go past the web server root directory, which is 

associated with certain web attacks.

TCP Decoder

BAD-LENGTH-OPTIONS 

ATTACK

This is when a TCP packet is sent where the TCP option 

length field is not the same as what it actually is or is 0. 

This may cause some applications to crash.

EXPERIMENTAL-

OPTIONS ATTACK

This is when a TCP packet is sent which contains non-RFC-

complaint options. This may cause some applications to 

crash.

OBSOLETE-OPTIONS 

ATTACK

This is when a TCP packet is sent which contains obsolete 

RFC options.

OVERSIZE-OFFSET 

ATTACK

This is when a TCP packet is sent where the TCP data offset 

is larger than the payload. 

TRUNCATED-OPTIONS 

ATTACK

This is when a TCP packet is sent which doesn’t have 

enough data to read. This could mean the packet was 

truncated.

TTCP-DETECTED ATTACK T/TCP provides a way of bypassing the standard three-way 

handshake found in TCP, thus speeding up transactions. 

However, this could lead to unauthorized access to the 

system by spoofing connections.

UNDERSIZE-LEN ATTACK This is when a TCP packet is sent which has a TCP datagram 

length of less than 20 bytes. This may cause some 

applications to crash.

UNDERSIZE-OFFSET 

ATTACK

This is when a TCP packet is sent which has a TCP header 

length of less than 20 bytes.This may cause some 

applications to crash.

UDP Decoder

OVERSIZE-LEN ATTACK

This is when a UDP packet is sent which has a UDP length 

field of greater than the actual packet length. This may 

cause some applications to crash.

TRUNCATED-HEADER 

ATTACK

This is when a UDP packet is sent which has a UDP 

datagram length of less the UDP header length. This may 

cause some applications to crash.

UNDERSIZE-LEN ATTACK This is when a UDP packet is sent which has a UDP length 

field of less than 8 bytes. This may cause some applications 

to crash.

ICMP Decoder

TRUNCATED-ADDRESS-

HEADER ATTACK

This is when an ICMP packet is sent which has an ICMP 

datagram length of less than the ICMP address header 

length. This may cause some applications to crash.
