IoT is rising at an extremely fast rate with the introduction of IPv6 and the large rollout of Wi-Fi networks, and analysts predict that by 2020, the number of active wireless connected devices would reach 40 billion. The positive point is that we can do stuff we’ve never imagined before. But there’s also a negative point to IoT as with every good thing, it’s becoming an increasingly attractive target for cybercriminals. Increasing connected devices mean increasing avenues of attack and more incentives for hackers to threaten us unless we move quickly to resolve this growing security concern. The solution to this is IoT security.
What is IoT Security?
IoT Security is defined as the area dealing with making connected devices and its data secure and safe from hackers and data breaches. Security is the biggest concern in the current era of data and information, and the security of IoT systems is as important as the security of software systems.
How to enhance IoT Security?
Unfortunately, not much work is being done to make IoT devices secure. While businesses can’t stop IoT attacks in eternity, they can be vigilant in minimizing network security threats and safeguarding valuable data and IT systems. In a connected setting, this would allow devices to issue alerts when asked to perform unusual tasks, thereby reducing a hacker’s capabilities through a single entry point. Below we discuss some of the steps you can take to make your IoT devices and data safe.
Development agencies need to be committed to improving security. They must appoint or hire a specific team for security to do this effectively. They should ensure that safety measures are applied fully and at all levels of the design and development lifecycle. It involves ensuring that prior to shipping there are no vulnerabilities and reminding users of security updates.
UPnP is the protocol that allows the discovery of networked devices by other networked devices. Although this is necessary for scalability, it allows identification and monitoring of devices. It is designed to make it easier to deploy network devices without configuring manually by helping them discover each other automatically. The concern is that, due to bugs in the UPnP protocol, hackers may also be able to discover them from outside your local network. It’s best to completely turn off UPnP to improve the security of your product.
Hire Reliable Vendors
Companies that provide you with goods and services are as vulnerable as you are to IoT risks. For many chief information security officers, this is a major concern, especially those who rely on a complex third-party supply chain for the products they offer. In this space, monitoring and regulating vendor practices is a challenging task that many security teams deem impossible. But organizations must themselves pay attention to c=vetting the suppliers properly before buying devices. Make sure that they apply the minimum security standards to their devices.
Use Cloud Services Cautiously
Assess Your Own Devices
Organizations need to track all network connections and control traffic flow from and to their devices. To determine the level of access they should have, to keep them fully patched and up-to-date, and to protect end-to-end data in order to preserve their integrity, devices need to be evaluated. An alert should be flagged when unknown devices are connected to the network. Knowing what devices are linked to each other and what they do is a prerequisite for proper security.
There is no stopping IoT in the enterprise for better or for worse. Devices multiply, hackers become more creative, and with each passing day, the threats become greater and potentially devastating. If you don’t feel properly prepared, now is the time to get started. Research as much as you can and follow the best practices to secure your services and devices against intruders.
