How the IoT Will Change (Almost) Everything in Cybersecurity

Organizations looking to build or adopt connected devices should educate themselves and seek to address a few key questions.

How Can Businesses Address IoT Vulnerabilities?
The changes to the attack surface aren't beyond our abilities to address. Business can do a few simple things to increase their IoT security from the start:

• Change all default passwords. Simple cybersecurity best practices, like always resetting default passwords, will continue to be a vital first step in the age of the IoT.

• Like changing the password, using an encrypted connection whenever one is available is generally a good cybersecurity rule of thumb that helps to mitigate the risk of attack on the many endpoints within the IoT.

• Create guidelines to quickly call out anomalous behavior of sensors. Sensors perform a very specific task or set of tasks, so detecting any suspicious behavior should be relatively simple if the technology and personnel monitoring the network understand which behaviors are authorized upfront.

How Is the IoT Changing the Future of Securing Businesses?
In many ways, securing an IoT-enabled business requires much of the same, but the game has changed in that the sheer volume of endpoints, and thus the area to secure, is quickly multiplying. Businesses will need to move beyond traditional network and endpoint security, and be diligent in monitoring all network connections. Detection and response strategies will need to become more closely integrated with cybersecurity practices, and IT departments will be most effective by combining the power of technology and human oversight to keep a watchful eye over expanded attack surfaces.

This is particularly true for new and emerging threats, and an overreliance on technology will result in undue complacency, which is exactly what the cybercriminals want in prospective targets.
