The sophistication of hackers and state-level tools and technology used to perpetrate cybercrime is increasing in the post-pandemic age. The use of URL (web) filtering and DNS filtering to prevent malicious information from ever reaching your users is a critical step in averting such assaults.
With these safeguards in place against the Internet’s risks, the attack surface is greatly reduced, and the system is protected against ever-increasing cyber threats.
Both DNS filtering and URL filtering methods function with the support of Web Reputation Services. These services evaluate websites and provide a risk score based on the traffic of users, the threat history of pages on the domain, the age of observation, the geographic location, related networks, internal and external linkages, as well as other patterns in the context.
On the other hand, not everyone is certain about whether using DNS or URL filtering is a preferable security strategy. It might be challenging to decide on the correct combination of technologies for your security stack. It’s true that both DNS and URL filtering offer advantages that should be coupled for total web security when it comes to blocking shady emails and dubious websites.
SWG URL Filtering
Point of Repression
With the support of TLS inspection, which permits insight into encrypted HTTPS traffic, URL filter rules will safeguard and monitor employees even when they are not connected to the corporate network. By banning websites such as malware and fraudulent sites, IT administrators may take a proactive action to thwart malware downloads and phishing efforts.
DNS over HTTPS
The DNS over HTTPS (DoH) protocol employs HTTPS to encrypt DNS communication and has been gaining greater popularity. DNS communication cannot be falsified using this protocol since it uses HTTPS, but DNS filtering tools cannot see it. This traffic is examined via URL filtering.
In addition, a comprehensive Secure Web Gateway integrates URL filtering with an anti-malware engine, which stops malware at the point of entrance. Malware detection skills are vital, safeguarding consumers from dangerous assaults on the Internet.
These assaults may swiftly proliferate through the corporate network, infecting one host after another. Users and hosts will be protected from infection at the point of entry using a Secure Web Gateway, which includes URL screening and Malware Protection.
URL versus DNS filtering table
So to summarise, the ideal security strategy is to use a Secure Web Gateway to activate DNS and URL filtering simultaneously.
A deeper degree of security and control is provided by URL web filtering rather than DNS filtering, which protects against malicious sites and all traffic. Using URL filtering in conjunction with anti-malware traffic inspection as part of a Secure Web Gateway increases the flexibility of granularly defining access restrictions to specific websites.
The best method to safeguard your firm from cyber threats is by integrating both DNS filtering and URL web filtering for overall network security, greatly lowering the attack surface and limiting the likelihood of malware, ransomware and other assaults.
