Determining Internet Connectivity Security Requirements

Determining the security requirements for your Internet connectivity solution should include the following:

  • The security requirements dictated by the organization and the nature of its business.
  • The level of Internet access which will be granted to users.
  • The manner in which to implement Internet security requirements.

A few measures that you can implement to prevent internal users from accessing the Internet, or limit users from performing certain activities include:

  • Limit the bandwidth which users can utilize.
  • Specify a time period for which users can access the Internet.
  • Specify the sites which users can access.

An organization usually consists of different types of users needing different levels of Internet access to perform their functions. The methods which can be used to assign different levels of access to different users are:

  • Through packet filtering, you can define the ports that every computer residing on the private network is allowed to use. Packets can be filtered on:
    • IP address
    • Port numbers
  • You can use proxy server mechanisms, such as a internet Security and Acceleration (ISA) server to limit user access to the Internet and to limit access to only certain Internet services.

You can also control which Internet applications users are able to access and run. One method of limiting the Internet applications that users can execute is by filtering packets based on port numbers. TCP/IP packets include a source port number that indicates the application which created it; and a destination port number that indicates the application receiving the packet. Here, you can use a firewall to provide the packet filtering solution. If you configured a computer through Routing and Remote Access management console as your router, then you can configure the router to filter packets.
