Firewall necessary for Point to Point internet connections?
Firewall necessary for Point to Point internet connections? We have multiple point to point t1 connections to our sites and was wondering if a firewall should be in place to filter traffic. We are also implenting a microwave t1 from a service provider and was wondering if firewalls would be needed for just this or the wired as well. According to the microwave company no firewalls are needed. Do i really want to leave security in the hands of the ISP?
Re: Firewall necessary for Point to Point internet connections?
If you are buying private line T1 service from a carrier that connects 2 of your sites you would not use a firewall. Your traffic is never mixed with any other traffic. If your data is very sensitive, or if you have to comply with Payment Card Industry standards then you might want to encrypt your data, but a firewall would still not be necessary.
If you have a T1 connecting you to the Internet for Web browsing etc then you very much do need a firewall.
