DNS Security

How DNS Security Works And The Business Benefits

DNS Security provides protection from online threats such as viruses, malware, ransomware, phishing attacks and botnets. The Domain Name System (DNS) makes it so that we can use the Internet by remembering names, and computers can translate these names into machine-readable IP addresses to transfer information from websites, email servers, and file servers to your web browser or email client.

Do We Need DNS Security if our Business has Endpoint Antivirus?

Sure, but antivirus software can only detect known viruses while it’s running – and end users are notorious for turning off antivirus and the local firewall on their computers to avoid sluggish performance or install software that they “need” to do their job (or sometimes, really, to distract themselves from doing their job!). Managing this isn’t always as simple as enforcing domain policies – sometimes the culprits are in the executive suite.

Web-delivered malware can affect the entire business. If CryptoLocker or Petya or one of its ever-evolving variants destroys a shared drive containing overtime logs or customer invoices, who loses out? And there are other viruses that may be lurking undetected (Uroburos went undiscovered for years), silently stealing information or waiting to deliver a destructive payload.

DNS Security will not prevent all of these, but having multiple layers of security lowers the risk. What layers so you require? You need DNS Security, spam filtering, endpoint anti virus, sensible firewall rules, up-to-date software, regular reliable backups, and an aware workforce. Leaving a single door open makes all the rest of the locks pointless.

Is DNS Security Tricky to Deploy?

DNS security provides an opportunity for using DNS as a very basic, low-latency and low-bandwidth filter to protect users from phishing sites, botnets, and other risky websites – and a way to prevent access to inappropriate NSFW (not suitable for work) websites. By using DNS Security with a database of categorized websites you can be safer in the blink of an eye. The filter protects your network by only providing lookup requests with a valid IP address for safe websites, but returns a local IP address to deliver a block page for forbidden sites.

Can’t Users Bypass DNS Security?

End users may try to get around your filters. No DNS Security approach is immune to circumvention – both appliance-based and cloud DNS Security services can be bypassed. But you can take simple steps to limit your end users’ ability to access forbidden websites. It’s time to roll up your sleeves and set some firewall rules on your Internet gateway/router! You can block DNS requests to anything other than your approved DNS service and block all other DNS requests. If you use an external DNS server, you should allow only port 53/UDP to access the IP addresses of your chosen DNS Security service servers.

How DNS Security Works

WebTitan is our DNS Security product that allows you to monitor, control, secure and protect your business from online threats. It’s based in the cloud, it’s easy to use and is priced competitively. The two key functions of the product are – web security and web content control. A user types a URL into their browser, this request is sent to the WebTitan Cloud servers and based on a pre-defined policy, the request is allowed or blocked. If the request is blocked the user is presented with a block page informing them why it was blocked. If the user is allowed they are passed on to the requested URL

Frequently Asked Questions (FAQs)

What is the Meaning of DNS Protection?

DNS protection's meaning is based on how web content filtering blocks specific domains and web pages. DNS protection integrates web content filters with user browser activity by blocking pages from being loaded during the DNS lookup step. Users receive a warning message rather than being able to load a malicious web page in their browsers.

How DNS Security Works?

DNS security works by intercepting a browser’s query for a domain name and identifying if it’s on a blacklist. If the domain is blacklisted for hosting malicious or inappropriate content, users are blocked from loading the domain in their browsers. This web content filtering strategy improves data protection from phishing, malware, and ransomware.

What is DNS Security Software?

Every added layer of cybersecurity on infrastructure improves data protection, and DNS security software adds web content filtering to an organization’s security strategy. DNS security software blocks blacklisted domains and web pages from being accessed from the corporate network, which protects organizations from web-based threats such as malware and phishing.

What is a DNS Security Appliance?

Web content filters are one example of a DNS security appliance. A DNS security appliance is any added infrastructure that protects data and the internal environment leveraging DNS lookups. Blocking users from accessing malicious websites in their browsers on the corporate network is one cybersecurity strategy using DNS security appliances.
