Security concerning the HTTP Monitor and the Monitor can be looked upon in 2 ways. The first is restricting access.
To restrict access the security settings on the Monitor and HTTP Monitor tab must be used.
For TCP/IP these settings restrict access to the local host or to a list or don't restrict access at all.
Since Local host and No access restrictions speak for themselves we will discuss the access list further.
This is a comma-separated list of TCP/IP numbers of machines that are granted access. It is also possible to allow a range of numbers access by using the CIDR notation. Furthermore, you can make an exception for one or more numbers in a range by adding them to the list with a minus character in front:
PortSecurity=-10.0.0.4,10.0.0.0/24,127.0.0.1 This will deny access to host 10.0.0.4 but grant access to all other hosts in the range 10.0.0.0 to 10.0.0.255, as well as to the local server using the local host address.
Note
The first match in the access list will determine whether or not ITP/Server will grant access to the client.
