Recently, DDoS attacks against Dyn have taken advantage of home devices. So, how can you prevent your webcam or other IoT system from becoming an attack tool?
On October 21st, in the massive denial of service attack (DDoS) against DNS provider Dyn, many Internet of Things (IoT) devices were infected and used as part of the "Zombie Army", resulting in popular website access rates such as Amazon, Twitter and PayPal. Slower, this attack also highlights the long-standing vulnerability of IoT.
Research published by security firm ESET and the National Cyber ​​Security Alliance (NCSA) shows that while consumers may be aware of the security of the Internet of Things, many people have not taken steps to protect IoT devices in the home.
Michael Kaiser of NCSA pointed out: "What people need to know is that IoT devices in their homes may be used for these types of DDoS attacks."
According to ESET senior researcher Stephen Cobb, the good news for this study is that consumers are already aware of the serious safety issues of IoT.
Cobb said: "There is no doubt that from the Target attack to the Snowden revelation, people are increasingly aware of the importance of security."
In terms of public knowledge of IoT security issues, the ESET/NCSA study found the following:
â— 88% of consumers believe that IoT devices and the data they collect may be accessed by attackers
â— 85% know that attackers can access some computer network cameras to peer at them; 29% worry that someone may have visited their webcam or video call without their consent
â— 77% realized that some cars may be vulnerable to hacking; 45% are very or slightly worried that their car may be attacked
â— 76% are very worried or have some concerns about the complete security and privacy of networked intelligence
“The public is very concerned about connected devices, such as their response to connected toys,†Cobb said. “But we must better educate the public about how to protect their networks.â€
For example, the study found that 29% of consumers did not change their home router default password; another 15% did not even know if they had changed the password of the home router.
NCSA's Kaiser said: "If not properly protected, the home router may become the entry point for malware. The basic step in protecting the home network is to change the default factory password."
The ESET/NCSA study also provides five tips for consumers:1. Learn how to maintain the security of your IoT device. Consumers need to protect their IoT devices just as they protect their smartphones, tablets and home computers. At the same time, you should also set a strong password and read the manual to learn how to lock these devices.
2. Clean up the old application. Many people tend to keep applications indefinitely, even if we don't need to use them. We should check the device regularly to remove applications that are no longer in use.
3. Master your online status. Find out what information your device collects and how it is managed and stored.
4. Study by yourself. Before you buy an IoT device, check to see if it has security issues and is vulnerable to hacking.
5. Change the default settings on your home router. This is worth repeating once: the high-strength password of the home router prevents DDoS attacks.
