Security Evaluation of Unix Networks

Abstract

In recent years, computer networks have significantly increased in both complexity and number, and these networks are attractive targets for attack and intrusion. Unix networks being managed by the government and providing access to unclassified sensitive information are particularly vulnerable to attack. Ensuring the security of sensitive information will be one of the single most important management issues in computer/information security in the foreseeable future. Unfortunately, the number of automated security tools for Unix, as well as the number of computer security experts within DOD, has not increased sufficiently to keep up with the improvements in technology. The author proposes the concept of a security toolbox, containing a proposed standard set of automated security tools, to support Unix networks. The toolbox can be used to enhance system security, automating many of the security related tasks required of the network administrator. Additionally, organizational changes will be necessary to improve the availability of computer security advice and assistance. It is recommended that a study of the function and organization of computer security expertise be conducted, so that access to and validation of security tools, along with consistent guidance for network administrators and security officers, can be accomplished effectively. The combination of a security toolbox and expert advice can then help bridge the gap in the development of computer security expertise. Computer security, Unix,
