Today, the biggest threat posed to businesses and individuals comes from cyber criminals. The greatest threats to us in 2017 and beyond are the cyber criminals. Every time you log on to the Internet you make yourself vulnerable to all sorts of attacks. Updating and downloading options also present real dangers to us. These risks include viruses, spyware and other malware getting injected into your computers or any other Internet-enabled device you might be using. There are many avenues to safeguard and protect our valuable data and info from hackers and other malicious software. One of those avenues involves configuring your DNS Firewall settings correctly.
What is a DNS Firewall?
DNS, is an acronym used to denote, domain name system and as you might guess, this is the unique name your computer bears. Adding the suffix, “Firewall” changes the meaning of the phrase to now implying the networking measures and protocols adopted by the system to protect itself from known malicious Internet links and malware sites. The DNS firewall is responsible for preventing potentially dangerous and harmful scripts from executing and running in our computer systems.
Types of DNS Firewalls
There are two broad varieties of firewalls existing today. The first one is a simple DNS solution which permits general internet accessibility. Users have the option of basic app files and folders, mostly the ones having the .exe extensions. The second type of firewall acts to filter the TCP/IP network traffic moving from the Internet to the local server. The server ports ranging from 1 to 1023 always listens for requests coming from port 53 which corresponds to the UDP and TCP protocols and ports.
Cyber Security Measures
In the case of a threat, the DNS system responds by sending an error log to the teams in charge of cyber security at your firm. The security experts then start hunting for the bugs and errors in the network’s botnets and APTs to undo the anomalies infiltrating your systems.
Limitations of IDS/IPS Security Network Solutions
On any given day, the intrusion and detection protection systems, in enabled our electronic devices protect us from tens, maybe even hundreds of malicious intrusions without us even realizing. With time, however, smart hackers discovered exploits in the IPS and the IDS firewall protocols and went ahead to use to attack us and out networks. For us and our systems to stay safe and secure, it became necessary to deploy a second line of defense on top of the IDS/IPS security network solutions already in place. DNS firewall resolvers came with the added layer of protection in the form of the advanced persistent threats (APT) security solutions to block the hackers from accessing our private gateways.
Using Paid-for-System Security Software
It’s quite easy and straightforward to configure and start using a DNS firewall. Here’s how you would go about it: Purchase the software from an approved vendor and install it on your device. Edit the settings to suit your network security’s needs and wants, and you are as good as done. Alternatively, use software from reputable vendors to minimize the risks of hacks and malware attacks.
