As the world is quickly moving towards IoT devices, there are some inherent risks that can render your security system useless and vulnerable. We are talking about DDoS (distributed denial of service) attacks.
A DDoS attack happens when thousands of individuals across the planet with 
computers and internet access try to access your device/site/IP at the same time using a bot net. This results in a system overload leading to failures.
As a home owner who is looking to secure his or her home using an IoT device, it is important that you ask the right questions. Check out the features and see if it there are any vulnerabilities. Ask the seller about DDoS attacks and how they plan to counter one if they were to be attacked.
Make sure that the internet connection that your security system is connected to is secured using the best in high tech. A security device comes with a lot of features. Disable features that you don’t want or use. It is always better to use a wired connection instead of a wireless connection. Hire a professional to install and test your security system regularly.
