Today's Highlight: Internet Protocol Security (IPsec)

IPsec is a set of rules that helps keep communications over the Internet private and secure. It makes sure that data is kept confidential and unaltered and comes from a trusted source.

Components of IPsec:

- Authentication Header (AH): IP Protocol#51: Provides data integrity and authentication but not encryption.
- Encapsulating Security Payload (ESP): IP Protocol#50: Provides data integrity, authentication, and encryption.
- Security Associations (SA): Defines secure communication rules, including encryption and keys.
- Internet Key Exchange (IKE): sets up a secure, authenticated communication channel and negotiates SAs and key exchanges.

Modes:

- Transport: Encrypts only the payload of the IP packet. Used between-end devices for end-to-end connectivity.
- Tunnel: Encrypts both the payload and header. Used for network-to-network communications. Ex. 2 Routers or Firewalls.
