Avoiding security breaches: Top 5 ways to curb DNS leaks


For companies, security breaches can spell trauma. Imagine a dire situation where a data breach could release a company’s sensitive client account details and payment information to the general public. For tech startups, this could be disastrous. It could tarnish the company’s reputation and might even lead to the business shutting shop. Worse yet, it could hamper an economy.

In South Asia, India had witnessed one of its biggest data breach in the finance space. Data belonging to nearly 3.2 million payment cards were swindled, raising concerns over data security. Despite the rapid advancement of technology, businesses are now becoming increasingly prone to cyber threats. It’s challenging to protect information online, especially since identifying information is becoming much simpler. From malicious location tracking services to insecure DNS, businesses are looking at preventing DNS leaks through some of the industry’s best practices. Here are some ways to avert a DNS leak:

1.    Changing DNS servers:

If your internet service provider (ISP) assigned you a default DNS server, one of the simplest ways to ward them from tracking what you’re doing online is by changing your DNS server. It also comes with a perk – faster internet speed.

2.    Enforce a robust VPN with protection against DNS leaks:

Some VPNs carry an additional feature that scans your DNS requests to ensure that they are routed to the right VPN instead of directly relaying it to your internet service provider.

Looking for a quick solution when your VPN is not connected? When accessing your network adapter’s properties, select your preferred network from the available options, while ensuring that your internet provider’s DNS servers are not used.

3.    Avail VPN monitoring software:

In today’s tech-enabled market, there are a plethora of options available for VPN monitoring software. Some companies provide premium plans for the software which comes with ample support to fix DNS leaks.

4.    Disable Teredo:

Teredo is a technology that enables communication across IP protocols, which could expose the system’s internet connectivity to DNS leaks. To prevent this possibility, users have the option to disable teredo.

5.    Block all non-VPN traffic:

Install a strong firewall and enforce a configuration that will block all traffic that arises outside of the desired VPN. This has a two-pronged effect – it shuts off usage of your actual internet connection and protects the system from connecting to the ISP’s DNS servers.

Albeit the healthy drive to adapt to the latest technology or innovation is rampant, it comes at a cost. Startups and small businesses have not been more susceptible to data breaches or cyber threats, especially in a country like India, which is growing by the day. Users need to exercise caution and safety when availing online services, and companies should tag data privacy and security as high priority.
