RFC 1281 Guidelines for the Secure Operation November 1991 and operating systems do not provide the level of security that is desired and feasible today. Three types of advances are encouraged: (a) Improvements should be made in the basic security mechanisms already in place. Password security is generally poor throughout the Internet and can be improved markedly through the use of tools to administer password assignment and through the use of better authentication technology. At the same time, the Internet user population is expanding to include a larger percentage of technically unsophisticated users. Security defaults on delivered systems and the controls for administering security must be geared to this growing population. (b) Security extensions to the protocol suite are needed. Candidate protocols which should be augmented to improve security include network management, routing, file transfer, telnet, and mail. (c) The design and implementation of operating systems should be improved to place more emphasis on security and pay more attention to the quality of the implementation of security within systems on the Internet.APPENDIX A Five areas should be addressed in improving local security: (1) There must be a clear statement of the local security policy, and this policy must be communicated to the users and other relevant parties. The policy should be on file and available to users at all times, and should be communicated to users as part of providing access to the system. (2) Adequate security controls must be implemented. At a minimum, this means controlling access to systems via passwords, instituting sound password management, and configuring the system to protect itself and the information within it. (3) There must be a capability to monitor security compliance and respond to incidents involving violation of security. Logs of logins, attempted logins, and other security-relevant events are strongly advised, as well as regular audit of these logs. Also recommended is a capability to trace connections and other events in response to penetrations. However, it is important for service providers to have a well thought out and publishedPethia, Crocker, & Fraser [Page 6]RFC 1281 Guidelines for the Secure Operation November 1991 policy about what information they gather, who has access to it and for what purposes. Maintaining the privacy of network users should be kept in mind when developing such a policy. (4) There must be an established chain of communication and control to handle security matters. A responsible person should be identified as the security contact. The means for reaching the security contact should be made known to all users and should be registered in public directories, and it should be easy for computer emergency response centers to find contact information at any time. The security contact should be familiar with the technology and configuration of all systems at the site or should be able to get in touch with those who have this knowledge at any time. Likewise, the security contact should be pre-authorized to make a best effort to deal with a security incident, or should be able to contact those with the authority at any time. (5) Sites and networks which are notified of security incidents should respond in a timely and effective manner. In the case of penetrations or other violations, sites and networks should allocate resources and capabilities to identify the nature of the incident and limit the damage. A site or network cannot be considered to have good security if it does not respond to incidents in a timely and effective fashion. If a violator can be identified, appropriate action should be taken to ensure that no further violations are caused. Exactly what sanctions should be brought against a violator depend on the nature of the incident and the site environment. For example, a university may choose to bring internal disciplinary action against a student violator. Similarly, sites and networks should respond when notified of security flaws in their systems. Sites and networks have the responsibility to install fixes in their systems as they become available.Pethia, Crocker, & Fraser [Page 7]RFC 1281 Guidelines for the Secure Operation November 1991A Bibliography of Computer and Network Security Related DocumentsUnited States Public Laws (PL) and Federal Policies [1] P.L. 100-235, "The Computer Security Act of 1987", (Contained in Appendix C of Citation No. 12, Vol II.), Jan. 8, 1988.
