The National Security Agency (NSA) is an intelligence agency of the United States Department of Defense, under the authority of the Director of National Intelligence (DNI). The NSA is responsible for global monitoring, collection, and processing of information and data for global intelligence and counterintelligence purposes, specializing in a discipline known as signals intelligence (SIGINT). The NSA is also tasked with the protection of U.S. communications networks and information systems. The NSA relies on a variety of measures to accomplish its mission, the majority of which are clandestine. The NSA has roughly 32,000 employees.
Pretty Good Privacy (PGP) is an encryption program that provides cryptographic privacy and authentication for data communication. PGP is used for signing, encrypting, and decrypting texts, e-mails, files, directories, and whole disk partitions and to increase the security of e-mail communications. Phil Zimmermann developed PGP in 1991.
Computer and network surveillance is the monitoring of computer activity and data stored locally on a computer or data being transferred over computer networks such as the Internet. This monitoring is often carried out covertly and may be completed by governments, corporations, criminal organizations, or individuals. It may or may not be legal and may or may not require authorization from a court or other independent government agencies. Computer and network surveillance programs are widespread today and almost all Internet traffic can be monitored.
The Drug Enforcement Administration (DEA) is a United States federal law enforcement agency under the U.S. Department of Justice tasked with combating illicit drug trafficking and distribution within the U.S. It is the lead agency for domestic enforcement of the Controlled Substances Act, sharing concurrent jurisdiction with the Federal Bureau of Investigation and U.S. Customs and Border Protection. The DEA is responsible for coordinating and pursuing U.S. drug investigations both domestically and internationally.
MDA, mda or variants may refer to:
DPA may refer to:
The Home Office (HO), also known as the Home Department, is a ministerial department of the Government of the United Kingdom. It is responsible for immigration, security, and law and order. As such, it is responsible for policing in England and Wales, fire and rescue services in England, Border Force, visas and immigration, and the Security Service (MI5). It is also in charge of government policy on security-related issues such as drugs, counterterrorism, and immigration. It was formerly responsible for His Majesty's Prison Service and the National Probation Service, but these have been transferred to the Ministry of Justice.
The Clipper chip was a chipset that was developed and promoted by the United States National Security Agency (NSA) as an encryption device that secured "voice and data messages" with a built-in backdoor that was intended to "allow Federal, State, and local law enforcement officials the ability to decode intercepted voice and data transmissions." It was intended to be adopted by telecommunications companies for voice transmission. Introduced in 1993, it was entirely defunct by 1996.
In the United States, a special agent is an official title used to refer to certain investigators or detectives of federal, military, tribal, or state agencies who primarily serve in criminal investigatory positions. Additionally, some special agents operate in criminal intelligence, counterterrorism, or counterintelligence-based roles as well, with one or all of these roles occasionally taking precedence over criminal investigatory tasks.
In the United States, the removal of cannabis from Schedule I of the Controlled Substances Act, the category reserved for drugs that have "no currently accepted medical use", is a proposed legal and administrative change in cannabis-related law at the federal level. After being proposed repeatedly since 1972, the U.S. Department of Justice initiated 2024 rulemaking to reschedule cannabis to Schedule III of the Controlled Substances Act. The majority of 2024 public comments supported descheduling, decriminalizing, or legalizing marijuana at the federal level.
The inelastic mean free path (IMFP) is an index of how far an electron on average travels through a solid before losing energy.
Diethanolamine, often abbreviated as DEA or DEOA, is an organic compound with the formula HN(CH2CH2OH)2. Pure diethanolamine is a white solid at room temperature, but its tendencies to absorb water and to supercool often results in it being found in a colorless, viscous liquid state. Diethanolamine is polyfunctional, being a secondary amine and a diol. Like other organic amines, diethanolamine acts as a weak base. Reflecting the hydrophilic character of the secondary amine and hydroxyl groups, DEA is soluble in water. Amides prepared from DEA are often also hydrophilic. In 2013, the chemical was classified by the International Agency for Research on Cancer as "possibly carcinogenic to humans" (Group 2B).
Cryptography is the practice and study of encrypting information, or in other words, securing information from unauthorized access. There are many different cryptography laws in different nations. Some countries prohibit the export of cryptography software and/or encryption algorithms or cryptoanalysis methods. Some countries require decryption keys to be recoverable in case of a police investigation.
Cryptography, or cryptology, is the practice and study of techniques for secure communication in the presence of adversarial behavior. More generally, cryptography is about constructing and analyzing protocols that prevent third parties or the public from reading private messages. Modern cryptography exists at the intersection of the disciplines of mathematics, computer science, information security, electrical engineering, digital signal processing, physics, and others. Core concepts related to information security are also central to cryptography. Practical applications of cryptography include electronic commerce, chip-based payment cards, digital currencies, computer passwords, and military communications.
The following outline is provided as an overview of and topical guide to cryptography:
BlackEnergy Malware was first reported in 2007 as an HTTP-based toolkit that generated bots to execute distributed denial of service attacks. It was created by Russian hacker Dmyrtro Oleksiuk around 2007. Oleksiuk also utilized the alias Cr4sh. In 2010, BlackEnergy 2 emerged with capabilities beyond DDoS. In 2014, BlackEnergy 3 came equipped with a variety of plug-ins. A Russian-based group known as Sandworm is attributed with using BlackEnergy targeted attacks. The attack is distributed via a Word document or PowerPoint attachment in an email, luring victims into clicking the seemingly legitimate file.
