The Coroner's Toolkit
The Coroner's Toolkit (or TCT) is a suite of free computer security programs by Dan Farmer and Wietse Venema for digital forensic analysis. The suite runs under several Unix-related operating systems: FreeBSD, OpenBSD, BSD/OS, SunOS/Solaris, Linux, and HP-UX. TCT is released under the terms of the IBM Public License. Parts of TCT can be used to aid analysis of and data recovery from computer disasters. TCT was superseded by The Sleuth Kit The Sleuth Kit (TSK) is a library and collection of Unix- and Windows-based utilities for extracting data from disk drives and other storage so as to facilitate the forensic analysis of computer systems. It forms the foundation for Autopsy, a bet .... Although TSK is only partially based on TCT, the authors of TCT have accepted it as official successor to TCT.

Dan Farmer
Dan Farmer (born April 5, 1962) is an American computer security researcher and programmer who was a pioneer in the development of vulnerability scanners for Unix operating systems and computer networks. Life and career Farmer developed his first software suite while he was a computer science student at Purdue University in 1989. Gene Spafford, one of his professors, helped him to start the project. The software, called the Computer Oracle and Password System (COPS), comprises several small, specialized vulnerability scanners designed to identify security weaknesses in one part of a Unix operating system. In 1995, Farmer and Wietse Venema (a Dutch programmer and physicist) developed a second vulnerability scanner called the Security Administrator Tool for Analyzing Networks (SATAN). Due to a misunderstanding of SATAN's capabilities, when it was first published, some network administrators and law enforcement personnel believed that hackers would use it to identify and break ...

OpenBSD
OpenBSD is a security-focused, free and open-source, Unix-like operating system based on the Berkeley Software Distribution (BSD). Theo de Raadt created OpenBSD in 1995 by forking NetBSD 1.0. According to the website, the OpenBSD project emphasizes "portability, standardization, correctness, proactive security and integrated cryptography." The OpenBSD project maintains portable versions of many subsystems as packages for other operating systems. Because of the project's preferred BSD license, many components are reused in proprietary and corporate-sponsored software projects. The firewall code in Apple's macOS is based on OpenBSD's PF firewall code, Android's Bionic C standard library is based on OpenBSD code, LLVM uses OpenBSD's regular expression library, and Windows 10 uses OpenSSH (OpenBSD Secure Shell) with LibreSSL. The word "open" in the name OpenBSD refers to the availability of the operating system source code on the Internet, although the word "open" in the nam ...

Unix Security-related Software
Unix (; trademarked as UNIX) is a family of multitasking, multiuser computer operating systems that derive from the original AT&T Unix, whose development started in 1969 at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others. Initially intended for use inside the Bell System, AT&T licensed Unix to outside parties in the late 1970s, leading to a variety of both academic and commercial Unix variants from vendors including University of California, Berkeley (BSD), Microsoft (Xenix), Sun Microsystems ( SunOS/Solaris), HP/ HPE (HP-UX), and IBM (AIX). In the early 1990s, AT&T sold its rights in Unix to Novell, which then sold the UNIX trademark to The Open Group, an industry consortium founded in 1996. The Open Group allows the use of the mark for certified operating systems that comply with the Single UNIX Specification (SUS). Unix systems are characterized by a modular design that is sometimes called the "Unix philosophy". According to this philosophy, ...

The Sleuth Kit
The Sleuth Kit (TSK) is a library and collection of Unix- and Windows-based utilities for extracting data from disk drives and other storage so as to facilitate the forensic analysis of computer systems. It forms the foundation for Autopsy, a better known tool that is essentially a graphical user interface to the command line utilities bundled with The Sleuth Kit. The collection is open source and protected by the GPL, the CPL and the IPL. The software is under active development and it is supported by a team of developers. The initial development was done by Brian Carrier who based it on The Coroner's Toolkit. It is the official successor platform. The Sleuth Kit is capable of parsing NTFS, FAT/ExFAT, UFS 1/2, Ext2, Ext3, Ext4, HFS, ISO 9660 and YAFFS2 file systems either separately or within disk images stored in raw ( dd), Expert Witness or AFF formats. The Sleuth Kit can be used to examine most Microsoft Windows, most Apple Macintosh OSX, many Linux and some other UNI ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HP-UX
HP-UX (from "Hewlett Packard Unix") is Hewlett Packard Enterprise's proprietary implementation of the Unix operating system, based on Unix System V (initially System III) and first released in 1984. Current versions support HPE Integrity Servers, based on Intel's Itanium architecture. Earlier versions of HP-UX supported the HP Integral PC and HP 9000 Series 200, 300, and 400 computer systems based on the Motorola 68000 series of processors, the HP 9000 Series 500 computers based on HP's proprietary FOCUS architecture, and later HP 9000 Series models based on HP's PA-RISC instruction set architecture. HP-UX was the first Unix to offer access control lists for file access permissions as an alternative to the standard Unix permissions system. HP-UX was also among the first Unix systems to include a built-in logical volume manager. HP has had a long partnership with Veritas Software, and uses VxFS as the primary file system. It is one of four commercial operating systems that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linux
Linux ( or ) is a family of open-source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically packaged as a Linux distribution, which includes the kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name "GNU/Linux" to emphasize the importance of GNU software, causing some controversy. Popular Linux distributions include Debian, Fedora Linux, and Ubuntu, the latter of which itself consists of many different distributions and modifications, including Lubuntu and Xubuntu. Commercial distributions include Red Hat Enterprise Linux and SUSE Linux Enterprise. Desktop Linux distributions include a windowing system such as X11 or Wayland, and a desktop environment such as GNOME or KDE Plasma. Distributions intended for ser ...

Solaris (operating System)
Solaris is a proprietary Unix operating system originally developed by Sun Microsystems. After the Sun acquisition by Oracle in 2010, it was renamed Oracle Solaris. Solaris superseded the company's earlier SunOS in 1993, and became known for its scalability, especially on SPARC systems, and for originating many innovative features such as DTrace, ZFS and Time Slider. Solaris supports SPARC and x86-64 workstations and servers from Oracle and other vendors. Solaris was registered as compliant with the Single UNIX Specification until 29 April 2019. Historically, Solaris was developed as proprietary software. In June 2005, Sun Microsystems released most of the codebase under the CDDL license, and founded the OpenSolaris open-source project. With OpenSolaris, Sun wanted to build a developer and user community around the software. After the acquisition of Sun Microsystems in January 2010, Oracle decided to discontinue the OpenSolaris distribution and the development model. In Aug ...

SunOS
SunOS is a Unix-branded operating system developed by Sun Microsystems for their workstation and server computer systems. The ''SunOS'' name is usually only used to refer to versions 1.0 to 4.1.4, which were based on BSD, while versions 5.0 and later are based on UNIX System V Release 4, and are marketed under the brand name ''Solaris''. History SunOS 1 only supported the Sun-2 series systems, including Sun-1 systems upgraded with Sun-2 (68010) CPU boards. SunOS 2 supported Sun-2 and Sun-3 (68020) series systems. SunOS 4 supported Sun-2 (until release 4.0.3), Sun-3 (until 4.1.1), Sun386i (4.0, 4.0.1 and 4.0.2 only) and Sun-4 (SPARC) architectures. Although SunOS 4 was intended to be the first release to fully support Sun's new SPARC processor, there was also a SunOS 3.2 release with preliminary support for Sun-4 systems. SunOS 4.1.2 introduced support for Sun's first sun4m-architecture multiprocessor machines (the SPARCserver 600MP series); since it ...

BSD/OS
BSD/OS (originally called BSD/386 and sometimes known as BSDi) is a discontinued proprietary version of the BSD operating system developed by Berkeley Software Design, Inc. (BSDi). BSD/OS had a reputation for reliability in server roles; the renowned Unix programmer and author W. Richard Stevens used it for his own personal web server. History BSDi was formed in 1991 by members of the Computer Systems Research Group (CSRG) at UC Berkeley to develop and sell a proprietary version of BSD Unix for PC compatible systems with Intel 386 (or later) processors. This made use of work previously done by Bill Jolitz to port BSD to the PC platform. BSD/386 1.0 was released in March 1993. The company sold licenses and support for it, taking advantage of terms in the BSD License which permit use of the BSD software in proprietary systems, as long the author is credited. The company in turn contributed code and resources to the development of non-proprietary BSD operating systems. In the mea ...

FreeBSD
FreeBSD is a free and open-source Unix-like operating system descended from the Berkeley Software Distribution (BSD), which was based on Research Unix. The first version of FreeBSD was released in 1993. In 2005, FreeBSD was the most popular open-source BSD operating system, accounting for more than three-quarters of all installed and permissively licensed BSD systems. FreeBSD has similarities with Linux, with two major differences in scope and licensing: FreeBSD maintains a complete system, i.e. the project delivers a kernel, device drivers, userland utilities, and documentation, as opposed to Linux only delivering a kernel and drivers, and relying on third-parties for system software; FreeBSD source code is generally released under a permissive BSD license, as opposed to the copyleft GPL used by Linux. The FreeBSD project includes a security team overseeing all software shipped in the base distribution. A wide range of additional third-party applications may be installe ...

Operating System
An operating system (OS) is system software that manages computer hardware, software resources, and provides common services for computer programs. Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, printing, and other resources. For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it. Operating systems are found on many devices that contain a computer from cellular phones and video game consoles to web servers and supercomputers. The dominant general-purpose personal computer operating system is Microsoft Windows with a market share of around 74.99%. macOS by Apple Inc. is in second place (14.84%), and ...
