The idea of the Internet of Things (IoT) started a few decades ago. Leading tech companies started exploring different ways in which seemingly unrelated devices at home and in the office could communicate with each other over the internet. Currently, this is a reality. Many people are using devices that can connect to the web. However, the Internet of Things has significant weaknesses as follows.
1. Failure to use encryption
Many IoT devices do not use encryption when communicating with each other. For example, when you remotely control your fridge back at home using your mobile phone, your refrigerator sends messages to your phone in clear text format. Encryption is important because it helps to hide messages from would-be hackers. However, many IoT devices forego using encryption. Therefore, it becomes easy for hackers to access communication among devices forming the internet of things.
2. Default login details
Most devices come with default login details. Manufacturers always advise clients to change the usernames and passwords before they start using the devices. Sadly, many people fail to modify the login details of their devices. Interestingly, hackers can search for the default login details of specific devices and use the information to hack into networks.
3. Outdated software
Many IoT devices run on old software. Currently, manufacturers of these devices are keener on sales than on ensuring that they have the required security software programs in place. Hackers can easily take advantage of outdated software in devices and launch sophisticated hacking attacks.
What you can do
- There is nothing much that you can do regarding the way IoT devices communicate with each other. It is up to developers to ensure that the devices use strong encryption protocols to communicate with each other.
- You should remember to change your login credentials before you start using a new IoT device. Changing your login details will protect you from hackers who prey on this particular vulnerability.
- You should be on the lookout for new security updates. Always take advantage of new security updates. Remember to install them promptly to protect your device from hackers.
