Password authentication protocol sends passwords unencrypted over a network and is insecure. It has been replaced by more secure protocols like CHAP and EAP, which use encryption techniques for authentication. CHAP uses a three-way handshake and shared secret, while EAP is an authentication framework with multiple protocols. Password authentication protocol is a way to send […]
Transaction authentication is a method of verifying a user’s identity for online transactions, often requiring a password and additional personal information. It is used in banking, sales, and personal data applications to prevent fraud. Additional security measures, such as transaction verification, can further protect against unauthorized access. Transaction authentication refers to an Internet method of […]
Strong authentication involves verifying a person’s identity through at least two of three factors: something they know, something they have, and something physically unique to them. Multiple challenges to the same factor do not improve verification. The reliability of an authentication system is a trade-off between security, ease of use, and cost constraints. Strong authentication […]
Multi-factor authentication uses multiple forms of verification to protect information. Two-factor authentication is a common example, requiring a passmark or security question after entering a user ID and password. Biometric verification can also be used. MFA is important for online security and building access control. Multi-factor authentication is an online security arrangement that uses several […]
Mutual authentication allows both parties in electronic communication to verify each other’s identity. It is used in private and public networks to prevent fraud and identity theft. TLS protocol is commonly used for mutual authentication. Sometimes referred to as two-way authentication, mutual authentication is an approach within the electronic communication process that allows both the […]
Pre-boot authentication requires an identifier before the operating system starts, making it more effective than OS authentication. It can be paired with disk encryption for better data protection. Different types of identifiers can be used, such as a username and password or biometric scanners. Pre-boot authentication is a process by which a computer requires input […]
Pre-boot authentication requires an identifier before the operating system starts, providing better data protection than OS authentication. It can be created between BIOS and OS boot and paired with disk encryption for added security. Different identifiers can be used, including biometric scanners and remote network authorization. Pre-boot authentication is a process by which a computer […]
The Internet Authentication Service (IAS) on Windows® ensures secure network use by enabling authentication, authorization, and accounting (AAA). AAA prevents unauthorized access, assigns user privileges, and tracks network usage for better budgeting. The Internet Authentication Service (IAS) on Windows® operating systems enables integrated authorization, authentication, and accounting for networks. Ensures that the network remains secure […]
Biometric authentication uses unique physical or behavioral traits to confirm identity and determine access. Physiological biometrics use physical traits like fingerprints, while behavioral biometrics use behavior like voice or gait. Data collected varies based on intended use, and can include tracking patterns and access times. Biometric authentication is the process of using a unique physical […]
A message authentication code (MAC) is a small block of data attached to a message to verify its integrity. The MAC is created at the same time as the message, and when the recipient opens it, the message content is run through an algorithm to create a new MAC, which is compared to the original. […]
