An Overview of Computer Viruses in a Research Environment Matt Bishop Department of Mathematics and Computer Science Dartmouth College Hanover, NH 03755 ABSTRACT The threat of attack by computer viruses is in reality a very small part of a much more general threat, specifically attacks aimed at subverting computer security. This paper examines computer viruses as malicious logic in a research and development environment, relates them to various models of security and integrity, and examines current

system’s security policy. Under DAC, the files are owned by the user also that user has full control over them. If an attacker penetrates that user’s account they can do whatever with the files owned by that user. Standard UNIX permissions are still present on the system, and will be consulted before the SElinux policy during access attempts. If the standard permissions deny access the access is denied so therefore SElinux is not involved. When the standard file permissions do allow access, the SElinux

threats of tampering and avoidance of security mechanisms, because DAC gives the user ownership of files and allows users the ability to make policy decisions and assign security attributes. Under MAC, administrators control every interaction on the software of the system. Standard UNIX permissions are still present, and are consulted before the SELinux policy during access attempts. When the standard file permissions allow access, the SELinux policy will be consulted and access is either gained or

Mac Memory Management For rough draft Mac OS is available on two processor architectures: the Motorola 68k series and the PowerPC. Mac OS has a flat address space, shared between all processes. There is no per-process memory protection. Application code runs in supervisor mode, so there is no instruction protection. Mac OS has virtual memory, in the limited sense that a larger fixed address space can be simulated, by storing the entire address space on disc. This size of this address space is
