The Importance of Multi-Layer Network Security

Network security is more important than ever, as hackers constantly strive to expose vulnerabilities and steal personal information. If your alarm system is associated with an interactive platform, then a flaw in network security could give an intruder easy access to your home or business.

The key to protecting your network and your personal information is to have multiple layers of security in place. You shouldn't just rely on one single security method, even if that one method is known for being very secure. If a vulnerability or an opening is ever exposed within that method's framework, then you could be left vulnerable.

An example of this can be seen in a vulnerability that was discovered in SonicWall Network Security Appliance (NSA) devices last month. This left more than 800,000 VPN appliances vulnerable. A patch has since been applied to these affected SonicWall devices, but that doesn't change the fact that many users were running unsecured VPNs for quite some time. Another example occurred last September, when it was found that FortiGate VPNs are vulnerable to Man-In-The-Middle (MITM) attacks when used in their default configuration.

This doesn't mean that using a VPN is a bad idea. Having a VPN in place is a great way to protect your network and your personal information. But it's important to understand that a VPN should be one of multiple protection layers keeping you safe. That way, even if your VPN fails, you will still have other mechanisms providing protection.

Network vulnerabilities can have severe consequences. Hackers can use vulnerabilities to access your personal information, including your passwords, credit card info, browsing history, and virtually all other data that you have shared with your network. In the context of a monitored security system, this can include information associated with an interactive service platform, such as Total Connect 2.0 or Alarm.com. Keep in mind that if an intruder accesses your TC2 or ADC account, they can disarm your system at-will and freely access your home or business. Having access to TC2 or ADC is basically the same as having a system code!

Fortunately, there are multiple security provisions you can set up to protect yourself. A strong VPN is a nice start. You should also set up firewalls as an added layer of security. And of course, always use secure, difficult-to-guess passwords, and never share them across different websites. You may also want to consider using two-factor authentication when available. Just yesterday, we made a post about two-factor authentication on Alarm.com. That is also an excellent way to keep your account protected.
