1. Firewall Service

Concerns about computer security dominate today's IT environment. But security is a broad subject encompassing many different areas. Properly securing a network involves the consideration of many aspects, and indeed the act of securing a network can never really be considered to be completed. It is an ongoing process.

The NSMS team offers a multifaceted security service, including the provision of a number of security-related services that can assist in the ongoing protection of your network. One of the key services is the provision of a firewall.

The Oxford University firewall primarily operates on a default-allow basis - essentially allowing all traffic in from outside, except that which has been explicitly blocked. While this serves to prevent many attack vectors on university hosts, it is not as secure as the alternative policy - to block all traffic except that which is explicitly allowed. This is a key reason for installing firewalls at the local level (either at the departmental gateway or on a host-by-host basis).

NSMS maintain a number of firewalls for colleges and departments around the university. Once a requirement for a firewall has been established, we will recommend a specific firewall model and configuration, after detailed discussions concerning network configuration and security requirements. Where the customer isn't certain about their network configuration and/or needs, we will investigate and make appropriate recommendations.

The NSMS firewall is covered by an annual support contract. The service offers the following features:

Should you need us, we offer telephone, email, and on-site support.
