DNS Firewalls Leading the Trend in Internet Security

DNS Firewalls Leading the Trend in Internet Security

The reason traditional firewalls are inadequate against today’s threats is because they leave certain elements in your enterprise systems completely unprotected. Cyber criminals use the loopholes to infiltrate your network hence the need for another firewall.

Introducing the DNS Firewall
Many business owners are now moving from firewalls and IDS/IPS solutions to DNS resolvers that function as firewalls for DNS to combat advanced persistent threats (APT) and other malware that beat traditional network defenses.

Extensive use of network security measures has not slowed down attackers who exploit unprotected DNS-based Internet infrastructure to infiltrate networks and steal valuable information without detection. Use of DNS firewalls could help prevent these attacks.

What is a DNS Firewall?
Apart from protecting the entire enterprise from malicious Internet attacks, Domain network server firewall provides immediate feedback about potential security threats. An enterprise can use DNS gateway to ensure its employees and IT systems are not routed to malicious Internet connections due to the addition of malicious domains or hostname to their server configuration.

Availability of the current DNS resolver infrastructure as a foundation is another advantage of a Domain network server firewall because it eliminates the need for you to install additional hardware, perform software upgrades, or reconfigure networks. DNS security solutions are the most preferred security measure for business networks

Why a Domain Network Server Firewall Is So Important
Unsecured business Internet networks pose various risks to organizations and their data. Many businesses are unable to protect their computer networks because some use outdated firewall security that are susceptible to advanced attacks.

One of the most common forms of malicious attack is known as spear phishing. It is difficult to detect because they mimic trusted sources. Such malware uses hostname or an algorithm to generate the host names instead of relying on hard-coded IP addresses when connecting to the server. Malware attacks can be detected through their DNS communication patterns. Businesses can prevent malware attacks by having a properly maintained Domain network server firewall that blocks access to information.

Driving Domain Network Server Firewall Adoption
A Domain network server firewall offers protection from breaches by identifying malicious host names that traditional firewalls cannot detect. Although DNS firewall have been around for many years, some companies have not adopted them because of over reliance on traditional firewall that may not be effective in protecting servers from certain malicious applications and users.

Traditional firewalls are great but the industry needs to protect the DNS layer from increased attacks by criminals and hackers who are aware of existing loopholes offered by traditional network security applications.
