EnCase
EnCase is the shared technology within a suite of digital investigations products by Guidance Software (acquired by OpenText in 2017). The software comes in several products designed for forensic, cyber security, security analytics, and e-discovery use. EnCase is traditionally used in forensics to recover evidence from seized hard drives. It allows the investigator to conduct in-depth analysis of user files to collect evidence such as documents, pictures, internet history and Windows Registry information. The company also offers EnCase training and certification. Data recovered by EnCase has been used in various court systems, such as in the cases of the BTK Killer and the murder of Danielle van Dam. Additional EnCase forensic work was documented in other cases such as the evidence provided for the Casey Anthony, Unabomber, and Mucko (Wakefield Massacre) cases. Company and Product Overview Guidance Software, and the Encase forensic tool, was originally created by Shawn H. M ...

Digital Forensic Process
The digital forensic process is a recognized scientific and forensic process used in digital forensics investigations. Forensics researcher Eoghan Casey defines it as a number of steps from the original incident alert through to reporting of findings. The process is predominantly used in computer and mobile forensic investigations and consists of three steps: ''acquisition'', ''analysis'' and ''reporting''. Digital media seized for investigation may become an "exhibit" in legal terminology if it is determined to be 'reliable'. Investigators employ the scientific method to recover digital evidence to support or disprove a hypothesis, either for a court of law or in civil proceedings. Personnel The stages of the digital forensics process require different specialist training and knowledge. There are two basic levels of personnel: ;Digital forensic technician :Technicians gather or process evidence at crime scenes. These technicians are trained on the correct handling of technolo ...

Computer Forensics
Computer forensics (also known as computer forensic science) is a branch of digital forensics, digital forensic science pertaining to evidence found in computers and digital storage media. The goal of computer forensics is to examine digital media in a forensically sound manner with the aim of identifying, preserving, recovering, analyzing, and presenting facts and opinions about the digital information. Although it is most often associated with the investigation of a wide variety of computer crime, computer forensics may also be used in civil proceedings. The discipline involves similar techniques and principles to data recovery, but with additional guidelines and practices designed to create a legal audit trail. Evidence from computer forensics investigations is usually subjected to the same guidelines and practices as other digital evidence. It has been used in a number of high-profile cases and is accepted as reliable within U.S. and European court systems. Overview In the ...

Unabomber
Theodore John Kaczynski ( ; May 22, 1942 – June 10, 2023), also known as the Unabomber ( ), was an American mathematician and domestic terrorist. He was a mathematics prodigy, but abandoned his academic career in 1969 to pursue a reclusive primitive lifestyle and lone wolf terrorism campaign to further his political agenda. Kaczynski murdered three people and injured 23 others between 1978 and 1995 in a nationwide mail bombing campaign against people he believed to be advancing modern technology and the destruction of the natural environment. He authored a roughly 35,000-word manifesto and social critique called '' Industrial Society and Its Future'' which opposes all forms of technology, rejects leftism and fascism, advocates cultural primitivism, and ultimately suggests violent revolution. In 1971, Kaczynski moved to a remote cabin without electricity or running water near Lincoln, Montana, where he lived as a recluse while learning survival skills to become sel ...

Law Enforcement Equipment
Law is a set of rules that are created and are enforceable by social or governmental institutions to regulate behavior, with its precise definition a matter of longstanding debate. It has been variously described as a science and as the art of justice. State-enforced laws can be made by a legislature, resulting in statutes; by the executive through decrees and regulations; or by judges' decisions, which form precedent in common law jurisdictions. An autocrat may exercise those functions within their realm. The creation of laws themselves may be influenced by a constitution, written or tacit, and the rights encoded therein. The law shapes politics, economics, history and society in various ways and also serves as a mediator of relations between people. Legal systems vary between jurisdictions, with their differences analysed in comparative law. In civil law jurisdictions, a legislature or other central body codifies and consolidates the law. In common law systems, judges m ...

Reverse Engineering
Reverse engineering (also known as backwards engineering or back engineering) is a process or method through which one attempts to understand through deductive reasoning how a previously made device, process, system, or piece of software accomplishes a task with very little (if any) insight into exactly how it does so. Depending on the system under consideration and the technologies employed, the knowledge gained during reverse engineering can help with repurposing obsolete objects, doing security analysis, or learning how something works. Although the process is specific to the object on which it is being performed, all reverse engineering processes consist of three basic steps: information extraction, modeling, and review. Information extraction is the practice of gathering all relevant information for performing the operation. Modeling is the practice of combining the gathered information into an abstract model, which can be used as a guide for designing the new object or syst ...

Hash Function
A hash function is any Function (mathematics), function that can be used to map data (computing), data of arbitrary size to fixed-size values, though there are some hash functions that support variable-length output. The values returned by a hash function are called ''hash values'', ''hash codes'', (''hash/message'') ''digests'', or simply ''hashes''. The values are usually used to index a fixed-size table called a ''hash table''. Use of a hash function to index a hash table is called ''hashing'' or ''scatter-storage addressing''. Hash functions and their associated hash tables are used in data storage and retrieval applications to access data in a small and nearly constant time per retrieval. They require an amount of storage space only fractionally greater than the total space required for the data or records themselves. Hashing is a computationally- and storage-space-efficient form of data access that avoids the non-constant access time of ordered and unordered lists and s ...
