DOMAIN NAME SYSTEM or DNS

HOW DOES DNS WORK?

Domain Name System or DNS

matches domain names

to IP addresses.

Essentially, DNS is a part

of accessing web content,

which cannot occur until

the DNS process happens.

WHAT IS DNS FILTERING?

DNS filtering is a process

of adding layered security

within your systems,

to ensure your business data

and content stay safe.

Have you had your DNS checked?

WHY SET UP DNS FILTERING?

ITC recently completed a job

adding DNS filtering and many top security measures to a system.

ITC CEO Doug Clark said, "Upon job completion, we rebooted the

system, and the first log came

within 30 minutes, which showed multiple attempts of spyware

and malware trying to

infiltrate their system."

HOW TO APPLY DNS FILTERS

There are several steps to add DNS filtering.

1. Connect to gateway

2. Connect devices

3. Connect DNS locations

4. Verify device connectivity

5. Add recommended and optional policies

There are additional steps in between each of the above items listed.

If you need your DNS checked or have questions contact ITC to assist in securing all of your technology.
