DNS Filter: Allow, Block, or Monitor Web Content

A domain name system (DNS) translates site names into something that a browser can comprehend. Examples are IP addresses — every time you go to a site, your browser sends a request to four caches: the OS, browser, router, and ISP caches. The cache that will acknowledge the request redirects it to another cache. Sometimes, it replies with an IP address. DNS has a basic capacity inside both the organization and the web, thus making it is an essential target for cybercriminals, so a DNS filter is important.

A powerful security strategy of a DNS filter includes blocking malicious queries. It also services user queries. A DNS filter plays a part in a layered system security strategy, as this includes various approaches to provide digital protection. This multi-layered method reduces the probability of cybercrime.

Usually, the ISP provides a DNS server that does all the activity, including reestablishing the IP addresses in response to web requests. In fact, you can use any DNS server for this reason, and there are many to choose from. A part of a DNS server can do something other than restoring IP addresses — for instance, advertisement blocking.

If you have a DNS filter enabled, all DNS requests will go through the DNS filter first. Then it will go to the DNS server. A DNS filter has a special simplified domain name filter thatcontains many tracker and advertisement domains. It is also called a vanity URL, which is a special web address used for marketing purposes. This is like a user filter that recognizes bad requests.

The main advantage of a DNS filter is its productivity. A DNS filter can battle spam, malware, pornography, and different risky sites on the web. It is also useful for organizations that need to ensure internal resources, as it can block known malicious sites. This function aims at the router level by blocking IP addresses. For those without the advantage of high-end routers, the use of a DNS filter is a great alternative.

Organizations use DNS filters at the router level. Search engines use techniques to mark IP addresses that carry malicious content. Anti-virus programs and web filtering software block downloadable content and websites that are suspicious by weighing all words on the given webpage, which avoids over-blocking or blocking a particular page by mistake. These strategies have worked well, yet cybercriminals are still looking for more ways to bypass protection.

Focusing on the endeavors of cybercriminals is challenging. There is an interconnected network that uses the web. They always register new domain names and move to clean locations. A security method will identify malicious activity and close it down. But these cybercriminals will simply move to another location, undetected. Then the cycle repeats itself.

There are links to bad sites all over the place, and cybercriminals use an assortment of strategies to draw people into clicking them. Also, there are many destinations that are malicious for multiple reasons.

The DNS filter should be a significant part of your system security strategy, used in conjunction with intrusion detection systems, port monitoring, antivirus, web filtering software, and firewalls. Together, these fundamental layers can work solidly to make a successful and reasonable security insurance framework.
