Hi, and a warm welcome to another riveting issue of "Cybersecurity Explained: The Sunday Edition." Today, we're about to embark on a journey into the realms of the cyber realm that often goes unnoticed but is pivotal in shaping your cybersecurity strategy: DNS filtering.

​

DNS Filtering - Beyond the Tech Jargon

Isn't cybersecurity just a universe filled with codes, firewalls, and encrypted mumbo jumbo? Think again! While those are vital elements, there's an unsung hero in the mix—DNS filtering.

Many businesses get caught up in the whirlwind of the latest tech tools but overlook this crucial layer that can make a monumental difference in safeguarding their operations.

​

Navigating the Cyber Sea with a Trusty Compass

DNS acts as our trusty compass in the vast ocean of the internet, where countless bytes of data sail seamlessly. Yet, it's baffling how many organizations don't give it the attention it deserves.

The common myth? "We've got the latest security software; we're invincible!" Sadly, that's like having a state-of-the-art ship without a compass—you might be sturdy but still lost.

​

DNS Vulnerabilities - The Silent Threats

Here's a sobering thought: while your high-tech defense systems might be repelling significant attacks, the unfiltered DNS traffic could quietly invite threats on board.

Like that unnoticed leak in a ship's hull, unchecked DNS traffic can slowly but surely sink the entire ship. The seemingly harmless domains might be trojan horses in disguise.

​

Navigating DNS Waters Safely

Wondering how to make the most of DNS filtering? Here's your game plan:

​

Regular audits: As you check your ship's equipment, periodically review and update your DNS filtering settings.

Educate your crew: Ensure your team understands the importance of DNS filtering and the risks of unchecked traffic.

Choose wisely: Opt for DNS providers known for their security features and diligence. Many providers filter the traffic for you, such as Cisco Umbrella.

Stay updated: The cyber sea is ever-changing. Keep abreast of the latest threats targeting DNS and adapt accordingly.

​

Wrap-Up: Set Your Course Right

DNS filtering isn't just another line item on your cybersecurity checklist; it's the compass guiding you through the unpredictable cyber seas. Your vessel—your business—depends on it to steer clear of hidden icebergs and reach its destination safely. Cybersecurity is as much about your path as it is about the vessel you're in.

Last week, I wrote about attack surfaces; you can read this here if you didn't get the chance. DNS traffic is also an attack surface that must be protected.

Stay vigilant, navigate wisely, and we'll see you in the next edition. Safe cyber sailing
