Type a web address into your browser and—voila!—the correlating website instantly appears. For this (at times) magically quick connection, you can thank the Internet's Domain Name System, or DNS.
For instance, when you enter www.xigentsolutions.com into your browser, the DNS syncs up the domain name with our site's IP address. This is referred to as "
making a DNS query." Depending on the size of your organization, hundreds, thousands, and even millions of DNS queries could be dispatched from your computer network on a given day.
Herein lies the cybersecurity concern: the DNS returns data from the targeted site without regard to its legitimacy or reputation. If it's a malicious site, or if it's a legitimate site that's been compromised, your networks could be exposed to a security threat.
This is where a DNS security solution can help. When implemented on your network, DNS security gathers intelligence on a site's reputation—before its data is sent back to your IP address. If there's any indication the site could pose a risk, DNS security will block access and alert the user. By preventing bad data from infiltrating your network, it can keep you from having to rely on your antivirus or firewall to catch it.
Here's what you should know about DNS security:
1. It's one of the easiest cybersecurity tools to implement.
The process for installing DNS security on your corporate network and devices is quick and painless. Because it's nearly impossible for the average user to know if a legitimate website has been compromised before visiting it, we see DNS security as one of the most cost-effective ways to prevent a cyber attack.
2. Your devices are protected whenever and wherever.
When properly implemented, DNS security protects your devices even when they aren't connected to the corporate network. This means your devices will be safer when used at Wi-Fi hotspots, employees' homes, or on other networks.
3. It can prevent internal cyber attacks, too.
Consider this scenario: A criminal drops a USB flash drive filled with ransomware in your company's parking lot. The drive is labeled "Administrative," so when an unsuspecting employee finds it, they plug it into their computer to see what it is and to whom it should be returned. When the drive's ransomware attempts to retrieve the encryption key from the criminal's website, DNS recognizes the site's reputation for malware and blocks the connection, saving you from a cyber attack in the process.
4. Certain solutions offer reporting capabilities.
These DNS security solutions can generate reports identifying the users or endpoints attempting to access malicious websites. With this information, you can address security gaps in your network before they become a problem.
Ready to safeguard your network with an extra layer of protection?
Most users don't think twice about visiting a website they deem reputable. But as cybercriminals become more and more savvy, simply surfing the Internet could leave your network vulnerable to a breach. If you'd like to explore how DNS security could help to mitigate your risk, give us a call today.
