Networking is a fundamental tool to the operation of various devices from simple IR blasters to systems that transmit low latency audio to high definition video. Even speakers which are known to be the dumbest audiovisual devices are now connected to a network. Although there are other devices where the network connection is used for remote management convenience, networking is crucial to most of these devices. The biggest problem with any network-connected system that has the capabilities of running code is that the system is at risk of being infiltrated via the same network connection and can be used in malicious acts. Additionally, when it comes to securing one’s devices, there have been no manufactures who has showcased a perfect record.
Cyber-attacks have been on the rise recently and they can range from sophisticated software programs to simple email phishing. The motives of the hackers can range from illegal profit to showcasing one’s technical expertise. Effects of hacking will not only affect individuals but it also affects the government and various businesses at large. How then can you protect your audiovisual networks from being hacked?

Although most audiovisual vendors have are seen to be slow in boarding this train, new firmware files signed cryptographically as a way of proving that they have not been maliciously tampered with by a third party and as a way of showing their integrity.
5. Demand better security service from manufactures.
Sometimes we as customers are the ones promoting security breaches because of financial incentive. You may be wondering why these attacks happen over and over but this is a result of having products that are not secure. Until customers take an initiative of demanding products from manufactures that are more secure to a point that manufactures will feel the pain of offering products that are secured poorly, we will continue to have bend backward in order to secure our networks.
