Summary

Network and system security have become increasingly important as more companies make use of public networks such as the Internet. The increased business and profits must offset the increased risk from unauthorized intruders; the latter could prove to be extremely costly.

Several products are available from Sun Microsystems , either included with the Solaris operating environment or as unbundled products. There are also an increasing number of products available to run on Solaris from third-party suppliers and in the public domain. Some tools available publicly are also those used by crackers to try to gain unauthorized access to systems and networks. System managers are well advised to be aware of these products so that any potential security holes can be filled at the earliest opportunity.

A central part of dealing with the computer security issue is formulating a security policy. This is the document that draws everything together, the resources that need protection, the risks associated with them, and the way in which they should be protected. It also contains the procedure to follow if an attack on a system or network is detected .
