Joey has proposed a new concept of “Continuously Usable Testing” for Debian [1], basically testing should be usable at all times and packages that aren’t usable should be dropped. But to properly achieve this goal we need continual testing of usability. The Plan For SE Linux To do this for SE Linux I’m setting up […] Yesterday and today I attended Ruxcon – the leading technical security conference in Australia [1]. The first lecture I attended was “Breaking Linux Security Protections” by Andrew Griffiths. This included a good overview of many current issues with Linux security. One thing that was particularly noteworthy was his mention of SE Linux policy, he cited […] Since the earliest days there has been a command named audit2allow that takes audit messages of operations that SE Linux denied and produces policy that will permit those operations. A lesser known option for this program is the “-R” option to use the interfaces from the Reference Policy (the newer version of the policy that […] One of the access controls in SE Linux is for execmem – which is used to stop processes from creating memory regions that are writable and executable (as they make it easier to compromise programs and get them to execute supplied code). When the SE Linux audit log tells you that a program is attempting […] My SE Linux Play Machine [1] has been offline for almost a month (it went offline late May 30 and has just gone online again). It’s the sort of downtime that can happen when you use Debian/Unstable. For a while I’ve been using a HP E-PC (a SFF desktop system with 256M of RAM and […] I have just uploaded refpolicy version 0.2.20100524-1 to Unstable. This policy is not well tested (a SE Linux policy package ending in “-1” is not something that tends to work well for all people) and in particular lacks testing for Desktop environments. But for servers it should work reasonably well. I expect to have a […] |
