you may mention that business has to protect their intellectual data as well as comform to governement regulations in protecting their employee's personal data. A company must protect certain data from outside resources as well as inside resources.
Companies have to protect sensitive information such as non-public financial data, business planning, patents, no market strategies, etc. This is information is transmitted across private and public networks and has to be secured while being transmitted. This information may be shared amongst employees on the private network as well as with commuters, and remote branch personnel.
Certainly, one depart such as payroll doesn't need non-hr persons to see this type of data and there need some internal security to be implemented while transmitting data.
The data may be secured in one or two factions, via tunnels using clear-text transmission or tunnels using encrypted transmissions such as IPSec and GRE Tunneling.
Besides firewall protection, you have data encryption, hashing, tunneling, hardening (removing vulnerabilites) of PC's, routers, and switches through the use of filter (similar to firewalling). You have device-to-device authentication using protocols such as PPP Chap, and Pap authentication.
