  4. 3. Comparative study of operating system security using SELinux and Systrace

    Kandidat-uppsats, Institutionen för kommunikation och design

    Författare :Jonas Öberg; [2009]
    Nyckelord :OpenBSD; Linux; security; SELinux; Systrace;

    Sammanfattning : This thesis makes a comparative study of the security systemsSystrace (used primarily with OpenBSD) and SELinux (usedexclusively with Linux), trying to answer the question as to whichtype of security is offered by each respective system, and wheneach should be used. The key difference between SELinux andSystrace seems to be their mode of operation, where SELinux,built around the LSM framework in the Linux kernel, works withtype enforcement on files, sockets and other objects, whereasSystrace works on a strict system call basis.

  5. 4. A Comparative Study of Security Features in FreeBSD and OpenBSD

    Magister-uppsats, Institutionen för informationsteknologi

    Författare :Magnus Persson; [2006]
    Nyckelord :FreeBSD; OpenBSD; UNIX; SEBSD; TrustedBSD;

    Sammanfattning : Security in operating systems is a highly topical subject nowadays as the Internet keeps expanding. The larger the Internet gets the more systems, with valuable information, get connected, which could be subjects of attacks. An operating system needs to protect its information from these attacks.
