Every system has a basic source of protection. For homes and offices, it is the security alarm system that keeps unwanted people out. For your computer, the DNS firewall is a protective fence that blocks the entry of malware. The firewall is so widely used that it is commonly found on the security checklists of many computer buyers. Learn more about DNS firewalls and where you need these devices the most.

The Regular Firewall is Not Enough

With so many identity thieves and hackers out there, your computer is not likely to survive without a firewall. Cyber criminals are working in groups and finding newer and better ways to divert the system. A regular firewall is no longer strong enough to secure an entire company. Some firewalls leave huge loopholes that are unprotected and undetected for years. Hackers take advantage of these areas by stealing information from the domain name system (DNS) in order to enter your network.

The Need for the DNS Firewall

A DNS firewall is also called the DNS resolver and it is designed to secure your Internet connections. The wall prevents you from entering malicious websites and sends messages to networks about security compromises. Securing your DNS gateway is necessary to prevent computer malfunctions, protect confidentiality and stop identity theft.

The DNS firewall is simple to use because there are no upgrades or installations required. Deploy your firewall in a few hours with the use of a few scripts. Not using a DNS resolver could cost you many hours of recovery for your data. Major search engines and corporations with unsecure resolvers have been attacked by malware agents. This happens when company employees open phishing emails, thinking they are trustworthy, and unwittingly release a virus. In many cases, the attacks are thwarted when people look into the log files and find out the malicious domain names. Finding out who the attackers is simple just like installing a protective firewall.

Hackers are taking advantage of the loopholes found in unsecure DNS infrastructures. They are forcing their ways into private networks and stealing personal information. Many of the top government agencies, search engines and Fortune 500 companies have become victims of these scams. For years to come, the number of threats will remain stable, even as security software becomes more advanced. Individual computer users should expect that they are likely to fall victim. All IT users should know that the DNS firewall is one of the most reliable lines of defense against the majority of attacks.
