TWiki Security Alerts
Please check the TWikiSecurityAlerts - list of all security alerts, sorted by TWiki releases. The alerts are compiled automatically from the KnownIssuesOfTWiki topics.
Security Related Topics
AllSecurityTopicsList - a list of all topics in all webs on twiki.org with "secur" in the title.
TWikiCodebaseSecurityAudit - discussion setting the guidelines for doing a security audit. A critical component for the next twiki release (DakarRelease).
TaintChecking is a very old discussion but sadly relevant here... Good reason for proactive security audits.
WikiSpam Topics
WikiSpam is not a security issue, but it can reduce the usefulness of public TWiki sites - install BlackListPlugin to counter this.
PasswordSecurityDiscussions - a largely philosophical discussion on the relative merits of using passwords as a security device.
SecureSetup - some good ideas on how to 'sandbox' TWiki a bit more.
WikiSecurityPhilosophy - musings on the principles behind "classic" wiki security and the path twiki has taken -- sometimes in concert, sometimes apart. Largely historical and in need of refactoring.
