You should have this in your lab if you're into networking and security. However, regardless of the hardware or software solution, the configuration of IPsec is essentially the same. + +## Context + +Organizations handling sensitive data must comply with various regulatory requirements such as PCI-DSS for payment card information or HIPAA for healthcare data. These regulations mandate the use of strong encryption when transmitting sensitive information across public networks. + +IPsec (Internet Protocol Security) provides a comprehensive framework for securing IP communications through authentication, integrity checking, and encryption. A site-to-site IPsec VPN creates a secure tunnel between two networks, allowing remote locations to communicate securely over the internet. + +## Topology + +``` +Site A Network: 192.168.10.0/24 +Router A (R1) ---- Internet ---- Router B (R2) + Site B Network: 192.168.20.0/24 + +R1 WAN Interface: 203.0.113.1/30 +R2 WAN Interface: 203.0.113.2/30 +``` + +**Network Details:** +- Site A LAN: 192.168.10.0/24 +- Site B LAN: 192.168.20.0/24 +- WAN Link: 203.0.113.0/30 + +--- + +![Network Topology](https://git.naxslabs.com/darnellkeith/cisco-ipsec-s2s/raw/branch/main/topology.png) + + +## Configs +Running configurations will be posted here. +See [NAXS Labs](https://naxslabs.com/protecting-sensitive-data-with-ipsec/) for full explanation. \ No newline at end of file
