- Hardened steel
Unreferenced date November 2008 The term hardened steel is often used for a plain carbon steel medium or high carbon steel that has been given the heat treatments of quenching followed by tempering . The quenching results in the formation of metastable martensite , the fraction of which is reduced to the desired amount during tempering. This is the most common state for finished articles such as tools and machine parts. In contrast, the same steel composition in annealing metallurgy annealed state will be softer as required for forming and machining . Case hardened articles starting as low carbon steel can also be labeled hardened steel. Category Steels alloy stub ... more details

- Hardened Gentoo
Hardened Gentoo is a project of Gentoo Linux that is enhancing the distribution with security addons. Current security enhancements to Gentoo Linux can be SELinux A system of mandatory access controls. SELinux can enforce the security policy over all processes and objects in the system, and is an optional feature in all 2.6 kernel source packages. RSBAC A mandatory access control security system based on Generalized Framework for Access Control GFAC . It provides several standard and custom and mixables access control models. It can enforce operating system access rules. PaX grsecurity grsecurity is a complete security solution providing such features as a mandatory access control MAC or RBAC system, chroot restrictions, address space modification protection via PaX , auditing features, randomization features, linking restrictions to prevent file race conditions, ipc protections and much more. Hardened Toolchain Transparent implementation of PaX address space layout randomization s and stack smashing protections using Executable and Linkable Format ELF shared objects as executables. sys kernel hardened sources A kernel source package which includes patches for hardened subprojects, and stability security oriented patches, including Grsecurity . Bastille Linux Bastille Linux is an interactive application which gives the user suggestions on securing their machine. It will be customized to make suggestions about other Hardened Gentoo subprojects. The Mandatory Access Control MAC parts of SELinux, RSBAC and grsecurity are usually incompatible to each other. However, the chroot and network restrictions of grsecurity and the memory protection of PaX can be used with the SELinux MAC model for example.

- Hardened Aircraft Shelter
Unreferenced date January 2008 File HAS Bruggen.jpg thumb right Hardened Aircraft Shelter at RAF Bruggen , 1981 Hardened Aircraft Shelters HAS , or Protective Aircraft Shelter PAS , are a reinforced structure to house and protect military aircraft from enemy attack. Cost considerations and building practicalities limit their use to Fighter aircraft fighter size aircraft. Background HAS s are a passive defence measure, i.e., they limit the effect of an attack, as opposed to active defences e.g., surface to air missile s which aim to prevent or at least degrade enemy attacks. The widespread adoption of Hardened Aircraft Shelters can be traced back to lessons learned in the 1967 Arab Israeli Six Day War when the Israeli Air Force decimated the unprotected Egyptian Air Force , at the time the largest and most advanced air force in the Arab world, at its airbase s. File F16 Hangar.jpg thumb left An F 16 being towed into a Hardened Aircraft Shelter at Volkel Air Base As with many military items, whether structures, tank s or aircraft, its most prolific use was during the Cold War . NATO and Warsaw Pact countries built hundreds of HAS s across Europe . In this context Hardened Aircraft Shelters were built to protect aircraft from conventional attacks as well as nuclear weapon nuclear , chemical warfare chemical and biological warfare biological strikes. NATO shelters, built to standard designs across the continent, were designed to withstand a direct hit by a 500lb 226 kg bomb, or a near miss by a larger one i.e., 1,000 lb .
