Internet Newsgroups

Another important body for both network administrators and intruders themselves is Internet newsgroups. Newsgroups are mailing list-type forums where individuals share ideas and past incidents to keep current with the latest security concerns and protection policies. As a network administrator, you must be aware of both standards and topics that intruders are discussing.

The following mailing lists and newsgroups are CERT/CC recommended:
