Term 312
Multilevel security is a computer security approach that allows users with different clearance levels to access data at different classification levels on the same system, while preventing unauthorized access.
Term 313
Network Access Control (NAC) is a security technology that enforces policies to control which devices and users can connect to a network.
Term 314
A Named ACL is a list of rules applied to a network device, identified by a name instead of a number, that controls which traffic is allowed or blocked based on source and destination IP addresses, protocols, and port numbers.
Term 315
NAT (Network Address Translation) is a method that allows multiple devices on a private network to share a single public IP address when accessing the internet.
Term 316
A NAT Gateway is a managed AWS service that allows instances in a private subnet to connect to the internet or other AWS services while preventing the internet from initiating connections back to those instances.
Term 317
A NAT instance is a virtual machine that forwards traffic from a private subnet to the internet, performing Network Address Translation (NAT) so that private instances can reach the internet without exposing them to inbound connections.
Term 318
NAT overload is a form of network address translation that allows many devices on a private network to share a single public IP address by using unique port numbers to track each connection.
Term 319
A native VLAN is the default VLAN assigned to a trunk port that carries untagged traffic for backwards compatibility with devices that do not understand VLAN tagging.
Term 320
A Native VLAN mismatch occurs when two connected switches have different Native VLANs configured on the trunk port, causing control traffic like CDP, DTP, and BPDUs to be sent on the wrong VLAN and potentially creating security vulnerabilities or connectivity issues.
Term 321
A legally binding contract that restricts the sharing of confidential information with unauthorized parties.
Term 322
Need to know is a security principle that restricts access to information or resources only to individuals who require that access to perform their job duties.
Term 323

Term 330
A numbered ACL is an access control list on a router or firewall that uses a number to identify the list and define rules for permitting or denying traffic based on source and destination IP addresses, ports, and protocols.
