One of the main problems with using SNMP vl and v2 is the clear text "community string" that it uses to authenticate. It is easy to sniff and reuse. Most times, the SNMP community string is shared throughout the organization's servers and routers, making this authentication problem a serious threat to security. There have been some isolated cases of remote buffer overflows against SNMP daemons, but generally that is not a problem. Cross site scripting is a web application vulnerability that is not related to SNMP. A man-in- the-middlc attack against a user datagram protocol (UDP) makes no sense since there is no active session; every request has the community string and is answered independently.

In the design phase, security checkpoints are defined and a test plan is developed. The testing phase is too late since the system has already been developed and is in production testing. In the initiation phase, the basic security objective of the project is acknowledged. Development is the coding phase and is too late to consider test plans.
