How to Prevent DNS Poisoning?

DNS poisoning is a form of hacking that allows the attacker to redirect your website visitors to different websites. It can lead to significant losses for businesses, but it doesn’t have to be this way. In this post, you will learn how dns poisoning works so you can prevent attacks on your company’s domain name. We will also discuss DNS protection methods and other ways that companies are defending against these types of cyber-attacks.

Understand what DNS poisoning Is

DNS poisoning, also known as DNS spoofing, allows an attacker to redirect users from a safe website address to another website. For example, when someone types in yourcompanyname.com into their web browser and they are redirected to another site that you have no control over or knowledge of. This can happen because the hacker can intercept all incoming data requests before they reach your company’s server so he/she knows exactly where visitors want to go next.

Once this happens it is very difficult for the user or internet service provider (ISP) who is sending out these messages on behalf of its customers – such as AT&T, Comcast Cable Company etcetera – since the information has been falsified by the cyber-criminal withs the intent of stealing information or defrauding the company.

How to Prevent DNS Poisoning

There are several easy steps you can take to prevent this from happening:

Get your company’s name registered with the ISP. This will prevent people from impersonating you and redirecting visitors to a different website that could harm your business reputation
Use more than one DNS provider – this is extremely important because if just one of them gets hacked, it won’t affect all of your traffic coming in and going out of the network
Purchase an SSL Certificate for encrypted communication between servers. Hackers can intercept unsecured information too easily so buy an SSL certificate to ensure safe data transfer while surfing the internet.
Review and maintain your DNS records to ensure that they are not compromised. If you notice any changes, contact the ISP immediately to report these suspicious activities so other users won’t be affected by them too.
Use a DNS Firewall. This is one of the most popular ways to protect against these types of attacks because it works by blocking malicious traffic before they reach their destination and deliver false information about your company’s website.

Other Ways Companies Have Prevented DNS Poisoning Attacks:

There are several other ways companies have prevented dns poisoning attacks such as installing high quality hardware devices or software programs like Cisco Umbrella which was built to prevent these types of attacks.

High-quality hardware devices will protect against DNS poisoning by ensuring your company’s data is safe at all times – no matter what kind of threat you are facing on the internet
Software programs like Cisco Umbrella can be installed onto any server offering free cloud security services that block out cybercriminals trying to steal information or harm your business in other ways

These solutions may seem costly, but they are worth it for protecting critical information about customers and financial transactions. Your ISP might also offer some form of DNS protection as well, so find out if this service is available through them before purchasing additional software or equipment. This way you can keep costs down while still keeping hackers away from harming your business.

Types of DNS poisoning

DNS poisoning is the act of redirecting website visitors to another site by falsifying their DNS information. There are two different types of DNS poisoning including:

Cache poisoning: this technique is used to corrupt DNS servers so they redirect visitors away from the actual website and instead send them to another site that can steal personal information or defraud companies
Pharming: This tactic involves changing the address of a trusted website into an untrusted one. This enables hackers who are trying to harm your business – by tricking customers into visiting their fake sites while thinking it’s safe.
Spoofing: this type of attack occurs when an attacker can intercept all incoming data requests before they reach your company’s server so he/she knows exactly where visitors want to go next; this leads to users being redirected to a fake or spoofed site.
Tampering: simple as it sounds, tampering refers to changing existing DNS records that have been stored in a local system. This could happen if someone has access to your router and changes the settings there but also happens through malware which steals login credentials from employees who use these devices for work purposes too.

Conclusion:

There are several ways you can prevent DNS poisoning attacks from happening to your company’s website. Make sure you get in touch with an ISP about registering your name and purchasing SSL certificates, configure the correct firewall settings onto all servers along with keeping a close eye on any changes made to domain records through various tamper tactics. This way you can ensure your data is safe and secure before any damage occurs.
