2) SMTP (Simple Mаil Trаnsfer Prоtоcоl) is the stаndard protocol for transferring mail between hosts over TCP. A TCP connection is set up between a user agent and a server program. The server listens on TCP port 25 for incoming connection requests. The user end of the connection is on a TCP port number above 1023. Suppose you wish to build a packet filter rule set allowing inbound and outbound SMTP traffic. You generate the following rule set: Rule Direction Src Addr Dest Addr Protocol Dest Port Action A In external internal TCP 25 permit B Out internal external TCP >1023 permit C Out internal external TCP 25 permit D In external internal TCP >1023 permit E Either any any any any deny b) Your host in this example has IP address 172.16.1.1. Someone tries to send email from a remote host with IP address 192.168.3.4. If successful, this generates an SMTP dialogue between the remote user and the SMTP server on your host consisting of SMTP commands and mail. Additionally, assume that a user on your host tries to send email to the SMTP server on the remote system. Four typical packets for this scenario are as shown: direction src addr dest addr protocol dest port action rule 1 In 192.168.3.4 172.16.1.1 TCP 25 ? ? 2 Out 172.16.1.1 192.1683.4 TCP 1234 ? ? 3 Out 172.16.1.1 192.168.3.4 TCP 25 ? ? 4 In 192.168.3.4 172.16.1.1 TCP 1357 ? ? Please indicate which packets are permitted or denied and which rule is used in each case.

Typical packets are as follows: direction src addr dest addr protocol dest port action rule 5 In 10.1.2.3 172.16.3.4 TCP 8080 ? ? 6 Out 172.16.3.4 10.1.2.3 TCP 5150 ? ? Will the attack succeed? By which above rules? Give details.
