• Security-Enhanced Linux.
• Security-Enhanced Linux (SELinux) is a Security-Enhanced version of GNU/Linux, which was primarily developed by the US National Security Agency (NSA) and released to the open source development community. ...
• From NSA Security-enhanced Linux Team: .
• "NSA Security-enhanced Linux is a set of patches to the Linux kernel and some utilities to incorporate a strong, flexible mandatory access control (MAC) architecture into the major subsystems of the kernel. It provides a mechanism to enforce the separation of information based on confidentiality and integrity requirements, which allows threats of tampering and bypassing of application security mechanisms to be addressed and enables the confinement of damage that can be caused by malicious or flawed applications. It includes a set of sample security policy configuration files designed to meet common, general-purpose security goals. ...
• Security-enhanced Linux is a research prototype of the Linux kernel and a number of utilities with enhanced security functionality designed simply to demonstrate the value of mandatory access controls to the Linux community and how such controls could be added to Linux. The Security-enhanced Linux kernel contains new architectural components originally developed to improve the security of the Flask operating system. These architectural components provide general support for the enforcement of many kinds of mandatory access control policies, including those based on the concepts of type enforcement, role-based access control, and multi-level security. ...
• The security-enhanced Linux kernel enforces mandatory access control policies that confine user programs and system servers to the minimum amount of privilege they require to do their jobs. ... It has no concept of a "root" super-user, and does not share the well-known shortcomings of the traditional Linux security mechanisms (such as a dependence on setuid/setgid binaries). ...
• The security of an unmodified Linux system depends on the correctness of the kernel, all the privileged applications, and each of their configurations. ... In contrast, the security of a modified system based on the security-enhanced Linux kernel depends primarily on the correctness of the kernel and its security policy configuration. While problems with the correctness or configuration of applications may allow the limited compromise of individual user programs and system daemons, they do not pose a threat to the security of other user programs and system daemons or to the security of the system as a whole. ...

• Memorandum on Computer and Network Security.

This memorandum is addressed to all computer users, urging them to play an active part in protecting themselves and their colleagues from these threats, and working together with their system managers. ...
• The last year saw a major growth in threats to computer and network security on the Internet. ...
• Some serious cases have forced the shutdown of site network connections for several days, with real consequences for work at those sites and knock-on effects at other sites. ...
• The use of computers and networks in the UK Academic Community is regulated not only by the Law, but also by the regulations of each University and Institute, and by the Acceptable Use Policy of the JANET network. ...
• Where Particle Physics is somewhat unusual is that our close international collaborations lead to users holding computer accounts at several sites: their University, RAL, CERN, DESY, SLAC etc. ... Most computer systems have at least one unidentified vulnerability whereby an attacker, having got access as a normal user, can achieve more-privileged status. ...
• All computer systems have points of weakness, and are capable of being penetrated by particular tricks. ... Not all attacks depend initially on carelessness by a particular user; but once a computer has been penetrated, the opportunities for further mayhem depend on what users have left lying around, such as pointers to accounts on other systems and, worse, passwords for those accounts. ...
• System managers of course try to keep abreast of the security fixes for loopholes as they are discovered, but each new discovery is a window of opportunity for the attackers, who use automated systems for scanning thousands of hosts, hunting for vulnerable systems on the network and penetrating them. ...
• The CNAP encourages the system managers to continue their work for improving security. ...
