How To Prevent DNS Poisoning
For Website Owners and DNS Service Providers
Website owners and DNS service providers have the responsibility of defending users from DNS attacks. There are several ways to protect your users.
1. DNS spoofing detection tools
These tools scan the DNS data being sent to make sure it is accurate before allowing it to go to the user.
2. Domain name system security extensions
A Domain Name System Security Extension (DNSSEC) appends a label to a DNS that verifies that it is authentic.
3. End-to-End encryption
With end-to-end encryption, the data that gets sent out is encrypted, so cyber criminals cannot access the DNS data to copy it and redirect users to the wrong sites.
For Endpoint Users
Users can be an easy target for DNS spoofing. Here are ways to prevent becoming a victim.
1. Never click a link you do not recognize
It is better to manually enter a Uniform Resource Locator (URL) into your web browser than click on a link that may look suspicious. Clicking the wrong link can lead to a DNS attack.
2. Regularly scan your computer for malware
Spoofed websites can be used by attackers to deliver malware to your computer. Regularly scanning your computer for infections can get rid of malware you downloaded accidentally as a result of DNS poisoning.
3. Flush your DNS cache to solve poisoning
Flushing your DNS cache gets rid of false information. All major operating systems come with cache-flushing functions. Flushing the DNS cache gives your device a fresh start, ensuring that any DNS information that gets processed will correlate with the correct site.
4. Use a Virtual Private Network (VPN)
With avirtual private network (VPN), all data going to and from your computer is encrypted. You can connect to a private DNS server that only connects using encryption. Cyber criminals do not have the encryption code so they cannot decipher the DNS data that gets sent back and forth.
