Application layer preprocessors are used by network security devices, such as firewalls, to perform deep inspection of application protocols. These preprocessors help in identifying and blocking potential security threats, such as malware, viruses, and intrusion attempts.

The two application layer preprocessors listed in the question are:

A. CIFS - Common Internet File System (CIFS) is a protocol used by Windows-based systems for sharing files and printers over a network. CIFS preprocessor can be used to identify and block suspicious traffic, such as unauthorized file access or attempts to exploit vulnerabilities in the protocol.

B. IMAP - Internet Message Access Protocol (IMAP) is a protocol used by email clients to access and manage emails stored on a server. IMAP preprocessor can be used to inspect email traffic for potential threats, such as phishing emails, malware attachments, or spam messages.

The other options listed in the question are not application layer preprocessors:

C. SSL - Secure Sockets Layer (SSL) is a protocol used to provide secure communication over the internet. SSL inspection is performed by SSL/TLS decryptors and not by application layer preprocessors.

D. DNP3 - Distributed Network Protocol (DNP3) is a protocol used in industrial control systems (ICS) to communicate with remote devices, such as sensors and controllers. DNP3 inspection is performed by ICS-specific preprocessors and not by application layer preprocessors.

E. ICMP - Internet Control Message Protocol (ICMP) is a protocol used for network diagnostic and error reporting. ICMP inspection is performed by network layer preprocessors and not by application layer preprocessors.
