In the foreseeable future, network security will still be a priority for most organizations. Hackers are still actively trying to infiltrate various network systems of companies and individuals. Blackmail software, malware, spyware and other unnecessary programs continue to infect systems, destroy data and steal intellectual property rights. The following are three main factors that will affect the future management of IoT devices.
Factor 1: the scale of the challenge
The Internet of things is changing the scale of security challenges. In the past, devices such as door locks or security cameras were based on physical mechanisms or specialized electronic circuits. Today’s camera, door lock, and firmware support are needed. It and security departments that used to manage corporate servers and laptops have found that they now need to manage a large number of networking devices to maintain network security.
Soon, more equipment will be added – environmental sensors, lighting controls, heating vents, etc. In the near future, each sprinkler in the garden irrigation system will be networked and driven by renewable firmware. By then, managers of large-scale systems will no longer manage hundreds of devices, but thousands, hundreds of thousands, or even millions of devices.
Factor 2: the nature of networking equipment
The nature of IoT devices is also changing, as the purpose of IoT devices is to improve the ability of interconnected systems. In the past, for example, the camera captured images and sent the video stream directly to the recorder via a dedicated cable. The camera and recorder perform their functions respectively and have different purposes.
Compared with the old method based on the function of each unit, this interoperability between network system units supports greater capability and flexibility. The new approach also supports large and complex systems, such as systems consisting of multiple vendor cameras. However, in order for it to work, the software of each unit must not only be maintained and updated in a way that protects it from network threats, but also updated in a manner compatible with each other unit in the system to support the required operations.
Looking to the future, IoT device manufacturers will face a huge and growing challenge of maintaining the continued security of their devices while maintaining interoperability with systems that will interact with their devices to perform the required functions.
Factor 3: the impact of improving safety
As mentioned above, today’s network environment includes hackers, malware, and automated attackers. In response, network equipment manufacturers have not only increased the basic security performance of their products, but also added a higher level of security protection. For example, some networked surveillance cameras not only need a password to access their management functions, but also now include a function that can temporarily lock the IP address if there are too many failed login attempts in succession.
As more and more systems will use multiple Internet of things devices to complete more and more extensive functions, the password of managing devices will become more and more important and complex. By taking a proactive approach to reduce the risk of IoT devices, organizations can reduce the attack surface of their networks, ensure compliance with applicable regulations, and allow time to focus on the most important security measures.
