An example of a physical security measure: a metal lock on the back of a personal computer to prevent hardware tampering. Computer security (also cybersecurity, digital security, or information technology (IT) security) is the protection of computer software, systems and networks from threats that can lead to unauthorized information disclosure, theft or damage to hardware, software, or data ...
Binary hardening is a security technique in which binary executables are analyzed and modified to protect against common exploits. Binary hardening is independent of compilers and involves the entire toolchain. For example, one binary hardening technique is to detect potential buffer overflows and to substitute the existing code with safer code.
The federal Canadian Cyber Incident Response Centre issued a security bulletin advising system administrators about the bug. [9] A fixed version of OpenSSL was released on 7 April 2014, on the same day Heartbleed was publicly disclosed. [10]
CyberPatriot began in 2009 as a proof-of-concept demonstration at AFA's Air Warfare Symposium in Orlando, Florida. [6] Four organizations were responsible for developing the competition: the Air Force Association, the U.S. Air Force, the defense contractor SAIC, and the Center for Infrastructure Assurance and Security (CIAS) at The University of Texas at San Antonio (UTSA).
A major goal in cryptography is to create cryptographic primitives with provable security. In some cases, cryptographic protocols are found to have information theoretic security; the one-time pad is a common example. However, information theoretic security cannot always be achieved; in such cases, cryptographers fall back to computational ...
In computer security, a cold boot attack (or to a lesser extent, a platform reset attack) is a type of side channel attack in which an attacker with physical access to a computer performs a memory dump of a computer's random-access memory (RAM) by performing a hard reset of the target machine.
Computer security compromised by hardware failure is a branch of computer security applied to hardware. The objective of computer security includes protection of information and property from theft, corruption, or natural disaster , while allowing the information and property to remain accessible and productive to its intended users.

A cybersecurity regulation comprises directives that safeguard information technology and computer systems with the purpose of forcing companies and organizations to protect their systems and information from cyberattacks like viruses, worms, Trojan horses, phishing, denial of service (DOS) attacks, unauthorized access (stealing intellectual property or confidential information) and control ...
