A compromised router is reconfigured by an attacker to redirect SMTP email traffic to the attacker's server before sending packets on to their intended destinations. Which IP header value would help expose anomalies in the path outbound SMTP/Port 25 traffic takes compared to outbound packets sent to other ports?
In a case study of a redirect tunnel set up on a router, some anomalies were noticed while watching network traffic with the TCPdump packet sniffer.
Packets going to port 25 (Simple Mail Transfer Protocol [SMTP] used by mail servers and other Mail Transfer Agents [MTAs] to send and receive e-mail) were apparently taking a different network path. The TLs were consistently three less than other destination ports, indicating another three network hops were taken.
Other IP header values listed, such as fragment offset. The acknowledgement number is a TCP, not IP, header field.

Which statement below is the MOST accurate about insider threat controls?
A company needs to classify its information as a key step in valuing it and knowing where to focus its protection.
Rotation of duties and separation of duties are both key elements in reducing the scope of information access and the ability to conceal malicious behavior.
Separation of duties helps minimize ''empire building'' within a company, keeping one individual from controlling a great deal of information, reducing the insider threat.
Security awareness programs can help other employees notice the signs of an insider attack and thus reduce the insider threat.
Detection is a reactive method and only occurs after an attack occurs. Only preventative methods can stop or limit an attack.
