What about IoT technology security?
Yes, it is all very charming to use advanced technology and gadgets that minimize effort and save you time. However, there are several IoT security issues that cannot be ignored and need serious attention. Hackers have a knack for finding loopholes and exploiting vulnerabilities in environments where data exchange is prevalent. They attack the apps, the gateways, data centers, the devices themselves, and more.
What’s worrisome is that some devices may have malware on them before you even get them. Once they’re installed, they corrupt the connected network and put its entire security at stake. Here are some potentially exploitable weak spots of IoT security:
- Unpatched Vulnerabilities. Sometimes there’s a connectivity issue in the devices forcing users to manually update and set the devices. This increases the chance of getting attacked due to outdated software. Hackers are quick at discovering back doors in older software and exploiting users this way.
- Exploitable APIs. APIs are a gateway to command and control centers. There are cases of APIs being routinely attacked with a variety of penetration methods.
- Weak Authentication. Devices with security passwords and no other factors of authentication are often easy targets for hackers. If the password is not timely updated, it may be vulnerable to unwanted remote access.
Privacy in the internet of things
Apart from security issues, consumers are very much concerned about privacy. IoT devices now know your daily schedule better than yourself, like when you wake up, brush your teeth, have coffee, leave home, and more. The question of who has access to this data, other than you, is a matter of concern. According to reports, a lot can be known about a person by simply gaining access to the data in IoT devices, and this is quite alarming.
Let’s brush through a list of some of the major IoT privacy issues:
- Unprotected data flows. The amount of data that IoT devices generate can be disturbing. Some reports show that households within just one city generate hundreds of millions of discrete data points on a daily basis. Without any protective measures, the result is more entry points for hackers and sensitive information being left out in the open.
- Undisclosed personal information. Companies could obtain access to personal data when customers agree to the terms and conditions for the provision of services. For instance, an insurance company can get access to information about your driving habits using a connected car when calculating your insurance rate.
- Eavesdropping: Invading homes virtually can be easily done by manufacturers or hackers using a connected device. A German researcher demonstrated this by intercepting unencrypted data from a smart device to reveal what television show someone was watching at that moment.
Each of these problems could hamper consumers’ desire to go ahead and purchase connected products. This would prevent the IoT from fulfilling its true potential.
