technical guide
Networks are a key part of the Grid vision, so network design must be considered as part of a Grid deployment. The physical networks to which Grid systems are connected, the allocation of IP addresses and the use of appropriate network controls can all have significant benefits for the performance and security of a Grid. Conversely, if these issues are not included in the early planning they can cause endless problems.

technical guide
Grid computing uses a distributed architecture to let teams of researchers in different physical locations and time zones collaborate on large scale projects in many disciplines. It is a novel application that involves new models of computing and new network protocols. Grids require complex and dynamic patterns of trust to be established and implemented, with computers relying on one another to make decisions on the identity and rights of individual users.

JANET(UK) recommends that organisations connected to JANET carry out their own internal monitoring of their network connection. On a simple level the JANET Netsight system can highlight abnormal traffic levels on a site's access link that may be a result of illegal activity. The JANET Factsheet Unusual Traffic gives examples of how Netsight can be used to detect these kinds of problems.

System configuration and maintenance

General-purpose computer systems as supplied are not designed to be connected to hostile networks. The Internet outside the organisation should certainly be regarded as hostile and for some purposes parts of the internal organisation should also be viewed in this light. This means that many of the computers in the organisation need additional configuration and maintenance to reduce the likelihood of them falling victim to an attack across the network.

firewalls
A firewall is a system that implements and enforces an access control (or security) policy between two networks, for example between an internal private network and an external public network. Essentially, a firewall connects two or more networks but only allows specified forms of traffic to flow between them.

Raising awareness

security
People are the most important component in any security system. Uninformed or unthinking users or administrators can make decisions for their own convenience that nullify all technical security measures. Aware and observant users and administrators can, however, reduce the likelihood and impact of security incidents even where only a few technical measures have been taken. Ideally organisations should aim to combine secure technology and security-conscious people into a truly robust system.

Organisations connected to JANET are required to comply with the JANET Security Policy, to protect the security of JANET and of their own internal networks. Further details are available in Section 9. JISC requires organisations with a Primary Connection to take responsibility for both the security of their own connection to JANET and the security of any Sponsored or Proxy Connections they provide.
