VPN security

Hi,

I want to know, apart from firewall, is there any other form of security on a network?

  • VPN

Re: VPN security

Lots of security-specific and non security-specific is available, example:

1. IDS/IPS - detect, classify, and stop threats, including worms, spyware/adware, network viruses embedded in network traffic, including application abuse.

2. CSA/NAC - Endpoint Security to safeguard computing devices (pc/workstation)

3. Cisco ACS - identity management

4. VPN Appliances - VPN3K, PIX/ASA, Router to provide secure IPSec tunnel across unsecure channel

5. Router with AdvanceSecurity features

Non security-specific devices like routers and switches are now embedded with security features (certain security features require license).

Re: VPN security

Have you checked out the SAFE page on cisco.com. It has pretty good information that should help you put together an objective for your project.

Re: VPN security

tamunoforiokuma1,

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.

Re: VPN security

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.
