The Gordon–Loeb model is an economic model that analyzes the optimal level of investment in information security. The benefits of investing in cybersecurity stem from reducing the costs associated with cyber breaches. The Gordon-Loeb model provides a framework for determining how much to invest in cybersecurity, using a cost-benefit approach.
Length extension attack. In cryptography and computer security, a length extension attack is a type of attack where an attacker can use Hash (message1) and the length of message1 to calculate Hash (message1 ‖ message2) for an attacker-controlled message2, without needing to know the content of message1. This is problematic when the hash is ...
Wi-Fi Protected Access. Wi-Fi Protected Access (WPA), Wi-Fi Protected Access 2 (WPA2), and Wi-Fi Protected Access 3 (WPA3) are the three security certification programs developed after 2000 by the Wi-Fi Alliance to secure wireless computer networks. The Alliance defined these in response to serious weaknesses researchers had found in the ...
The Common Vulnerability Scoring System (CVSS) is a free and open industry standard for assessing the severity of computer system security vulnerabilities. CVSS attempts to assign severity scores to vulnerabilities, allowing responders to prioritize responses and resources according to threat. Scores are calculated based on a formula that ...
