Computer security, cybersecurity, digital security or information technology security is the protection of computer systems and networks from attacks by malicious actors that may result in unauthorized information disclosure, theft of, or damage to hardware, software, or data, as well as from the disruption or misdirection of the services they provide.
Information security standards or cyber security standards are techniques generally outlined in published materials that attempt to protect the cyber environment of a user or organization. This environment includes users themselves, networks, devices, all software, processes, information in storage or transit, applications, services, and systems that can be connected directly or indirectly to networks.
The College of Engineering at the Georgia Institute of Technology provides formal education and research in more than 10 fields of engineering, including aerospace, chemical, civil engineering, electrical engineering, industrial, mechanical, materials engineering, biomedical, and biomolecular engineering, plus polymer, textile, and fiber engineering. The College of Engineering is the oldest and largest college of the institution.
A Hardware Trojan (HT) is a malicious modification of the circuitry of an integrated circuit. A hardware Trojan is completely characterized by its physical representation and its behavior. The payload of an HT is the entire activity that the Trojan executes when it is triggered. In general, Trojans try to bypass or disable the security fence of a system: for example, leaking confidential information by radio emission. HTs also could disable, damage or destroy the entire chip or components of it.
A cyberattack is any offensive maneuver that targets computer information systems, computer networks, infrastructures, personal computer devices, or smartphones. An attacker is a person or process that attempts to access data, functions, or other restricted areas of the system without authorization, potentially with malicious intent. Depending on the context, cyberattacks can be part of cyber warfare or cyberterrorism. A cyberattack can be employed by sovereign states, individuals, groups, societies or organizations and it may originate from an anonymous source. A product that facilitates a cyberattack is sometimes called a cyber weapon. Cyberattacks have increased over the last few years. A well-known example of a cyberattack is a distributed denial of service attack (DDoS).
Carl E. Landwehr is an American computer scientist whose research focus is cybersecurity and trustworthy computing. His work has addressed the identification of software vulnerabilities toward high assurance software development, architectures for intrusion-tolerant and multilevel security systems, token-based authentication, and system evaluation and certification methods. In an invited essay for ACSAC 2013, he proposed the idea of developing building codes for building software that is used in critical infrastructures. He has organized an NSF funded workshop to develop a building code and research agenda for medical device software security. The final committee report is available through the Cyber Security and Policy Institute of the George Washington University, and the building code through the IEEE.
The following outline is provided as an overview of and topical guide to computer security:
The President's Commission on Enhancing National Cybersecurity is a Presidential Commission formed on April 13, 2016, to develop a plan for protecting cyberspace, and America's economic reliance on it. The commission released its final report in December 2016. The report made recommendations regarding the intertwining roles of the military, government administration and the private sector in providing cyber security. Chairman Donilon said of the report that its coverage "is unusual in the breadth of issues" with which it deals.
In cybersecurity, cyber self-defense refers to self-defense against cyberattack. While it generally emphasizes active cybersecurity measures by computer users themselves, cyber self-defense is sometimes used to refer to the self-defense of organizations as a whole, such as corporate entities or entire nations. Surveillance self-defense is a variant of cyber self-defense and largely overlaps with it. Active and passive cybersecurity measures provide defenders with higher levels of cybersecurity, intrusion detection, incident handling and remediation capabilities. Various sectors and organizations are legally obligated to adhere to cyber security standards.
Robert E. Joyce is an American cybersecurity official who served as special assistant to the President and Cybersecurity Coordinator on the U.S. National Security Council. He also began serving as White House Homeland Security Adviser to President Donald Trump on an acting basis after the resignation of Tom Bossert from April 10, 2018 to May 31, 2018. He completed his detail to the White House in May 2018 and returned to the National Security Agency. where he is now the Senior Advisor to the Director NSA for Cyber Security Strategy, Joyce previously performed as acting Deputy Homeland Security Advisor since October 13, 2017. On January 15, 2021 the NSA announced that Joyce would replace Anne Neuberger as its Director of Cybersecurity.

He is the Intel Charles E. Young Preeminence Endowed Professor in Cybersecurity at the University of Florida and serves as the Director of the Florida Institute for Cybersecurity Research. Since June 2022, he has served as the chair of the Department of Electrical and Computer Engineering at the University of Florida. He is a fellow of IEEE, ACM, and NAI as well as a Golden Core member of the IEEE. He is a co-founder of the International Symposium on Hardware Oriented Security and Trust (HOST). He is the recipient of the 2023 SRC Aristotle award. Tehranipoor also serves as a co-director of the Air Force Office of Scientific Research CYAN and MEST Centers of Excellence.
Internet security awareness or Cyber security awareness refers to how much end-users know about the cyber security threats their networks face, the risks they introduce and mitigating security best practices to guide their behavior. End users are considered the weakest link and the primary vulnerability within a network. Since end-users are a major vulnerability, technical means to improve security are not enough. Organizations could also seek to reduce the risk of the human element. This could be accomplished by providing security best practice guidance for end users' awareness of cyber security. Employees could be taught about common threats and how to avoid or mitigate them.
