1. The three major categories used to provide authentication of an individual are something you are, something you have, and something you know. 2. Authorization is how an organization will assign and enforce access control rights. It is aligned with Identification and Authentication because it limits users who have a legitimate need for resources and it requires a strong password policy. 3. Three examples of Network Architecture Controls that help enforce data access policies at the LAN-to-WAN Domain level are SSO(Single Sign On), TKIP(Temporal Key Integrity Protocol), and SSID(Service Set Identifier). 4. LLC (Logical Link Control) and MAC(Media Access Control) 5. A NAC System, or Network Access Control system, is a policy where limited access to resources is granted to a computer that was just connected to the network. Once everything is scanned and checked, the NAC will grant the appropriate level of access. 6. A Public Key Infrastructure is a framework that consists of programs, procedures, and security policies that employ public key cryptography. In order to implement it, you would need to verify MAC addresses in the table. 7. PKI provides the capabilities of digital signatures and encryption to implement 8. The X.509 standard is for managing public keys through a PKI. X.509 certificates, where public keys are maintained, are digital documents that bind a user’s identity to a public key. 9. Regarding Biometric Access Controls, Identification is the process of taking a reading on an individual and comparing it to the previously stored data on that individual. Verification is similar but it compares a newly scanned characteristic to the data already
