Hello everyone! Rule Set Based Access Control (RSBAC) 1.3.5 has been released for both Linux kernels 2.4.34.5 and 2.6.22.1. You can download the new version from http://www.rsbac.org RSBAC is one of the leading access control systems for the Linux kernel with a good selection of access control models, see http://www.rsbac.org/why for more details. Important changes since 1.3.4: * Fixes compilation errors with some configurations. * Some safety measures with null pointers. * Fixes an important bug with User Management password hashing, introduced with newer 2.6 kernel crypto API. Major improvements over the 1.2.x series: Speed and scalability: - Cache for inherited filesystem attribute values - Automatically scaling hash tables for generic lists to minimize list lookups - Change network templates to handle up to 25 ip networks and up to 10 port ranges per template - Various smaller optimizations More control: - Fine grained setuid control also in RC (type of the target user) and ACL (acl at the target user) models - UNIX sockets as new filesystem target type, thus more fine grained control with RC types and ACLs - Further improved IPC communication control - RSBAC User Management password history with configurable length to avoid password reuse. - New request type AUTHENTICATE against USER targets. No authentication against RSBAC UM without this right in RC and ACL, so even harder to brute force attack Amon. -- http://www.rsbac.org - GnuPG: 2048g/5DEAAA30 2002-10-22
