Finally, you need to take action based on the reports generated.
The action may include informal warnings, publishing lists of frequent abusers
and using tools to control or limit access. There are tools available to control
specific types of applications, such as chat clients, Kazaa and download accelerators.
Also, there are tools that can perform multiple functions, such as control Web
access and chat simultaneously. Then there are tools that can do application
prioritization to help provide the QoS (Quality of Server) to applications that
really need it. Let’s talk about how to control these applications using various
tools.
For blocking sites, you can use a tool called SurfControl that
needs to be installed on a gateway machine (which in our case was Windows 2000
Advance Server). You can buy SurfControl for Rs 99,000 for 50 users from www.foresightho.com.
During installation, Surf- Control will prompt you to select the
network segment that you want to monitor and control. After installing it,
install MSDE (Microsoft’s SQL Data Engine). SurfControl provides its own
version of MSDE, which contains SurfControl’s rules database as well. The
software uses SQL database to store Web filters and polices.
