With an increasing number of businesses planning IoT deployments, a whole new set of security challenges have emerged. At the ground level, IoT is all about interconnectivity, and there lies the biggest issues. Enterprise networks connected to the cloud, online services, datacenters, and even employees’ devices will pave the way for security breaches by hackers and unauthorized users.
Here are 5 IoT security risks for which companies should be prepared:
1. Denial-of-service attacks
Disruptive cyberattacks or distributed denial-of-service (DDoS) attacks will pose severe threats to IoT devices. Most of the security breaches are expected to take place in the Bring-Your-Own-Device (BYOD) environment where the risks of device loss or theft are high. Enterprises need to take security measures to remotely manage devices, access and wipe out data and also disconnect compromised devices from the network. Www.Office.com/setup
2. Insecure end points
IoT inherently creates billions of insecure endpoints. IP-addressable devices will create new vectors of attack designed to either compromise the device or gain access to the enterprise network. These devices will not support currently available antivirus, anti-spam, or anti-malware programs. To address these concerns and prevent unauthorized access, companies will have to incorporate security controls, leveraging a pre-built role-based model.
3. Physical and physiological damage
In addition to data breach vulnerabilities, physical and physiological risks also cannot be ruled out, according to Michael Sutton, vice president of Zscaler. He said that intruders have already caused damages to wearers of Internet enabled insulin pumps, pacemakers and glucose monitors. Stuxnet is one example of such cyber attacks. Sutton warns that hackers may not even require any hardware or software vulnerabilities to break into these devices. They can simply hack them by tracing IPs. IP configuration errors are what enterprises must be careful of as these security flaws could be gateway to devices which will give access to company networks.avg.com/retail
4. IoT will inevitably intersect with the enterprise network
Amit Yoran, former director of the National Cyber Security Division at the U.S. Department of Homeland Security, has cautioned that “just as there are no truly standalone industrial control networks and air traffic control networks anymore, there won’t be a truly standalone enterprise network in an IoT world.” According to him, IoT and the enterprise network will intersect. If someone can hack into a web-enabled device which also happens to have connectivity to the corporate network or infrastructure, they can create a bridge to pass traffic back and forth.

5. Lack of bandwidth
Palo Alto Networks has published a study which states that there has been a rapid surge in network traffic from peer-to-peer application use, online media streaming and social networking. Gradually as more and more smart devices will be accessible via web, network traffic will grow by leaps and bounds. In order to maintain seamless flow of bandwidth and employee productivity, enterprises need to ensure that critical applications must receive the required bandwidth. Enterprises should opt for additional bandwidth to manage and monitor traffic and use web-based services. Thus, increased use of internet bandwidth will reduce business continuity risks and possible losses. Www.mcafee.com/activate
