Security and related policies

(Incomplete DRAFT page)

Security is founded on policy.
Although your organisation may have an all-embracing document called the "Security Policy", it is likely to bring together several distinct elements which may equally well be presented separately.

Local practice may be that detailed procedures for the implementation of policy are published in the policy document itself, or it may be considered normal for policies to be concise documents establishing principles which are rarely altered, keeping other details separately where they can be maintained at a lower level. This second way results in more individual documents and cross-references, but it may allow more flexibility.

Security Policy

Your security policy should say what you mean by security, what kinds of things it applies to and who is responsible for any tasks and duties identified.

Connection policy

A connection policy might set out how an item of equipment becomes authorised to connect to all or part of your network, on the basis of its ownership, its type, the status of its software or any other relevant information.
For wired networks both the specification and the enforcement of the policy are normally straightforward; the application of the policy to a wireless network is likely to be looser, leaving more to be resolved by Acceptable Use.

Access policy

It may be appropriate to separately describe the categories of people entitled to use the network in various ways, the procedures for authorisation, such as registration, and the procedures for removing or terminating authorisation.

Acceptable Use policy

An AUP contains the requirements on authorised users of the network. Normally it will state (for the avoidance of uncertainty) that no illegal activity is allowed, and there may be other classes of activity forbidden such as giving access to third parties, sharing credentials, or use in the course of a business other than that of the organization concerned. There will be some indication of the procedures for enforcement, although the details may be in separate documents; and of any arrangements for monitoring and limiting use.
