UNIX Security References
Security Periodicals

There have been a great many books, magazines and papers published on security in the last few years, reflecting the growing concern with the topic. Trying to keep up with even a subset of this information can be quite a chore, whether you wish to stay current as a researcher or as a practitioner. Here, we have collected information about a number of useful references that you can use as a starting point for more information, further depth, and additional assistance. We have tried to confine the list to accessible and especially valuable references that you will not have difficulty finding.[1] We've provided annotation where we think it will be helpful.

> [1] If you have some other generally accessible reference that you think is outstanding and that we omitted from this list, please let us know.

In Appendix E we also list some online resources in which you can find other publications and discussions on security. In Appendix F, we give pointers to a number of professional organizations (including ACM, Usenix, and the IEEE Computer Society) that sponsor periodic conferences on security; you may wish to locate the proceedings of those conferences as an additional reference. We especially recommend the proceedings of the annual Usenix Security Workshop: these are generally UNIX-related and more oriented toward practice than theory.
