Network Security VulnerabilitiesHow secure is your network? It’s never as secure as you think. No matter how sophisticated your firewall is, or how much protection you have against cyberattacks, you still have some cyber vulnerabilities in your system. After all, the attackers have you beaten by sheer numbers. They can bombard your network with tens of thousands of attacks every day, until one of them makes its way in. And all it takes is one, to ruin your entire company.

That’s why the biggest threat to your cybersecurity is your own hubris. Thinking that your system is safe will lead you to let your guard down, opening you up to real threats. Here are three cyber vulnerabilities that the hubris can prevent you from noticing.

#1: Information Overload

Relying on your firewall alone, with no other form of cyber protection, will result in overloading your security team. Those thousands of daily attempts to penetrate your system must be assessed and either allowed or denied. Your security team simply doesn’t have the time or the resources to do that with any degree of precision. The result is information overload.

Your team’s attempts to continually assess the risk of endless potential threats will result in bottlenecks to your system as they parse out the good from the bad, one by one. Meanwhile, with all of these potential threats piling up, they’ll find themselves not being as thorough as they should be and letting attackers through.

Thinking that your team can actually make sense of all the myriad reports that come through, and come up with an accurate assessment of threats and security gaps in your system, is one of the most damaging cyber vulnerabilities there is. You can’t handle that level of information on a daily basis without an extra level of protection.

#2: Thinking a Geo-Location layer will only hinder your security environment

One of those methods of extra protection is Geo-Filtering. However, a Geo-Location layer is often seen as a double edged sword. On the one hand, an IP address’s country of origin can be a good indicator of whether or not its request to access your system is an attempted cyberattack. Filtering out all IPs from that country can greatly reduce the number of threats your security team has to deal with, at a single blow.

On the other hand, blocking an entire country from accessing your network can mean blocking useful traffic as well, from legitimate users. Because of this, many people shun the Geo-IP layer entirely, thinking that they don’t need it, and it will do more harm than good.

What we don’t realize is that modern Geo-IP layering is more sophisticated than the blanket blockers of a few years ago. Modern Geo-Location filtering can distinguish themselves between potential threats and legitimate requests, protecting you from the former without shutting out the latter. By writing off Geo-Filtering entirely, companies leave themselves vulnerable to all of those relentless cyberattacks from countries that otherwise would have been filtered out from the first.

#3: Relying on a Geo-IP filter that’s built into your firewall

The second mistake that companies make to leave themselves open to cyberattacks is thinking that just any Geo-IP filter will do. While the problems mentioned above with blanket Geo-Filtering are not enough to warrant a total ban on Geo-IP filters, they still should be taken seriously.

A basic Geo-IP filter that’s pre-built into your firewall won’t be sophisticated enough to discern between threats and legitimate users. Rather, you need a separate Geo-IP layer, which screens all attempts to access your network before they even make it to your firewall. That extra layer of protection is what makes Geo-IP filtering such an important weapon. Building it into your firewall will render it less effective in discerning cyberattacks.

The surest way to open yourself up to cyber vulnerabilities is to think that your system is 100% safe. There’s no such thing as “total safety” and even the best methods of protection can fail you if you’re not careful. However, if you keep on your guard, have multiple layers of protection, and are always on the lookout for new threats, you can keep your system safe and secure.   {{cta(‘5371dc90-4116-481f-aa66-db0878143ba0′,’justifyright’)}}
