What Is DNS Filtering & Security? 

DNS filtering and security is a type of cyber security defense which blocks malicious or inappropriate content from being accessed within an organization’s networks. 

It works by scanning IP addresses associated with different websites and blocking access to those sites that are known to contain malware, phishing attempts, ransomware or other malicious content. 

DNS filtering also allows organizations to monitor internet usage and control access to certain types of websites, such as those with adult content. 

This type of security helps protect corporate networks from malicious activity and inappropriate content. 

How Does DNS Filtering Work? 

DNS filtering works by scanning the IP address associated with a website and blocking access if it is known to contain malicious or inappropriate content.

This information is gathered from public databases which list websites that have been identified as hosting malicious and/or inappropriate content. 

When a user visits a website, the DNS server looks up their IP address in the database and determines whether or not it should be blocked. 

If the website’s IP address is on the list of blocked websites, the user will not be able to access it.

The DNS filter also works in a similar way when monitoring internet usage within an organization

It scans the IP address associated with each website visited and can block certain types of content such as adult material or gambling sites. 

This type of security helps protect corporate networks from malicious activity and inappropriate content.

Why Is DNS Filtering Important? 

DNS filtering and security is important for any organization because it helps protect corporate networks from malicious content and inappropriate activity. 

By blocking access to websites with known malicious or inappropriate content, organizations can reduce the risk of their networks being hacked or used for nefarious purposes

By controlling access to certain types of websites, organizations can ensure that their employees are not accessing inappropriate content

DNS filtering and security is also important because it makes Internet usage more efficient and allows organizations to monitor the activities of their users. 

By blocking access to certain types of websites, DNS filters can help reduce bandwidth usage and make sure that user activities are not using up too much of the organization’s resources.

Here are some tips to help you get started:

  • Create a list of websites that you want blocked or monitored. This should include any websites with known malicious or inappropriate content, as well as sites you want to restrict access to (such as gambling websites or adult content). 
  • Configure your DNS filter to block or monitor the sites on your list. This can be done with a few simple clicks in most DNS filters, but you may need to consult with an IT expert or network administrator if you are not familiar with this type of technology.
  • Regularly update your DNS filter. Make sure to review your list of blocked sites and add any new ones that may have popped up since you last updated the filter. Additionally, make sure to run regular scans of your networks to check for malicious activity or inappropriate content.
  • Educate users on network security policies and procedures. Make sure that all users in your organization know the rules and regulations regarding network security so they understand why it is important to have a DNS filter in place.
  • Monitor user activity. Keep an eye on what users are doing online and make sure to take action if you see any suspicious activity or inappropriate content being accessed.

What Are The Benefits Of DNS Filtering? 

Using a DNS filter to secure your organization’s networks has many benefits, including improved network security and more efficient internet usage. 

From a security standpoint, using a DNS filter can help reduce the risk of malicious attacks on corporate networks by blocking access to websites that are known to contain malicious or inappropriate content.

From an efficiency standpoint, using a DNS filter can also help reduce bandwidth usage and make sure that user activities are not taking up too much of the organization’s resources. 

By blocking some websites, the filter can help reduce the overall load on the network and make sure that user activities are not disrupting other operations on the network.

It is very worth mentioning that investing in professional services when setting up a DNS filter can go a long way.

It can help protect corporate networks from malicious content and inappropriate activity while also reducing bandwidth usage and making sure user activities don’t take up too much resources. 

By creating a list of websites to block or monitor, configuring the filter accordingly, regularly updating it, educating users on network security policies, and monitoring user activity closely, you can ensure that your organization’s networks are safe and secure. 

In the digital age, you can never be too secure online and we heartily advise that you consider setting up one.
