The SELinux folk at MITRE have announced version 1.3 of their automated policy generation tool Polgen. Significant new features include Polgen Specification Language (PSL), presented at the recent SELinux Symposium (see here), and a new sourceforge project page, to facilitate greater community involvement in the project.

Announced here, there’s a new NSA release of the upstream SELinux code, notably including changes to semanage which allow manipulation of network nodes & ports, active booleans and file contexts.

A new release of the SELinux Reference Policy is now available on SourceForge from http://serefpolicy.sourceforge.net. The primary activity for this release has been renaming interfaces to improve the naming consistency, in an effort to stabilize the API.

Tresys have announced a new graphical policy development environment called SLIDE. It’s an Eclipse plugin and looks quite sophisticated. Screenshots!
