how can you detect these sniffing interfaces?

During the intelligence gathering phase of a penetration test, you come across a press release by
a security products vendor stating that they have signed a multi-million dollar agreement with the
company you are targeting. The contract was for vulnerability assessment tools and network
based IDS systems. While researching on that particular brand of IDS you notice that its default
installation allows it to perform sniffing and attack analysis on one NIC and caters to its
management and reporting on another NIC. The sniffing interface is completely unbound from the
TCP/IP stack by default. Assuming the defaults were used, how can you detect these sniffing
interfaces?

What type of technique might be used by these offenders to access the Internet without restriction?

Which of the following tools allows an attacker to intentionally craft packets to confuse pattern-matching NID

Most NIDS systems operate in layer 2 of the OSI model. These systems feed raw traffic into a
detection engine and rely on the pattern matching and/or statistical analysis to determine what is
malicious. Packets are not processed by the host’s TCP/IP stack allowing the NIDS to analyze
traffic the host would otherwise discard. Which of the following tools allows an attacker to
intentionally craft packets to confuse pattern-matching NIDS systems, while still being correctly
assembled by the host TCP/IP stack to render the attack payload?
