| Access Control List |
A set of rules that control network traffic by allowing or denying packets based on specified criteria such as source or destination IP address, port number, or protocol. |
| Authentication Header |
A protocol used in IPsec to provide data integrity, authentication, and anti-replay services. |
| Encapsulating Security Payload |
A protocol in IPsec that provides confidentiality, data integrity, and authentication of the packets. |
| Internet Protocol Security |
A protocol suite used for securing communications by authenticating and encrypting each IP packet of a communication session. |
| Intrusion Detection System |
A security tool that monitors network traffic for suspicious activity or security policy violations. |
| Key Management Protocol |
A protocol used to establish security associations in IPsec, allowing the negotiation of keys and algorithms for secure communication. |
| Security Association |
A set of security parameters negotiated between two IPsec peers for secure communication, including encryption algorithm, integrity algorithm, and keys. |
| Transport Mode |
An IPsec configuration where only the payload of the IP packet is encrypted and authenticated, while the original IP header remains intact. |
| Tunnel Mode |
An IPsec configuration where the entire IP packet is encapsulated within another IP packet for secure communication between networks. |
