Placing Proxy Server within a Network
You must place Proxy Server between network segments so that network traffic is localized and security is maintained.
To improve performance,
you can place Proxy Server so that Web objects are cached for:
A few key differences between placing Proxy Server within the private network and at the edge of the private network are detailed in the MouseOver below.
Question: Does a Proxy Server need to be placed between network segments so that network traffic is localized and security is maintained?
- An entire organization
- A location within an organization
- A network segment within an organization
A few key differences between placing Proxy Server within the private network and at the edge of the private network are detailed in the MouseOver below.
Answer:
Placing a proxy server between network segments can help to localize network traffic and improve security in certain scenarios. By acting as an intermediary between client devices and external servers, a proxy server can help to ensure that all traffic flows through a single point of control and inspection. This can be particularly useful in scenarios where traffic needs to be monitored or filtered for security purposes, such as restricting access to sensitive resources or blocking access to known malicious websites.
In addition, placing a proxy server between network segments can help to isolate network segments from one another, improving security and preventing the spread of malware or other threats. By limiting the ability of devices on one network segment to directly access devices on another network segment, the risk of unauthorized access or data breaches can be reduced.
However, there may be scenarios where placing a proxy server between network segments is not necessary or appropriate. For example, in a small network with a single internet gateway, it may be sufficient to use a proxy server only on the client devices themselves, without the need for an intermediary server between network segments. Ultimately, the decision to place a proxy server between network segments will depend on the specific needs and requirements of the organization or network. Factors such as the size and complexity of the network, the level of security required, and the need to monitor or filter traffic will all play a role in determining the best approach to take.

- When using a proxy server on the edge of each network segment, the overall network traffic on the internal network is reduced, because requests for similar content that have already been made by another user on the same segment, do not have to leave the local subnet.
- Web objects are cached for the entire organization. Screened subnets are created within the private network, thereby protecting confidential data.
- The private network is isolated from the public network, thereby protecting confidential data. Network packets can be exchanged between the private network segments and public network segments, such as between an Ethernet private network segment and an (ISDN) Integrated Services Digital Network public network segment.
