The Internet of Things is something that is increasingly present among users. We have at our disposal a wide range of possibilities and it will increase as technology advances. However, something that we must always keep in mind is security. Sometimes our information may be in danger, as well as the proper functioning of the systems. In this article we echo a new method to protect IoT devices connected to the network.
New method to protect IoT devices
Something very important to protect all kinds of equipment connected to the network is to have a good configuration. This means that we must take into account the possible security parameters that may exist, as well as the installation of security tools or having the latest patches correctly installed.
Now, the truth is that many users overlook these measures. They may have a misconfiguration on devices causing major security issues. Maybe they even have these systems out of date or that they don’t install programs that protect them from possible attacks.
Now they have created a new method from the National University of Singapore and the Ben-Gurion University of the Negev to improve this security and not depend so much on the users. Specifically, it is that telecommunications service providers will be able to monitor these devices and see if they are really insured.
According to this study, the ability to launch massive DDoS attacks through a botnet of compromised devices is an exponentially increasing risk in the Internet of Things. Such attacks, very frequently on IoT equipment in home networks, impact the target of the attack, as well as the infrastructure of telecommunications companies.
The researchers who have carried out this study indicate that most users do not have the necessary knowledge to avoid these attacks and effectively protect IoT devices.
Anticipate attacks
Each connected device has a unique IP address . However, home networks often use gateway routers with NAT functionality, which replace the local source IP address of each outgoing data packet with the public IP address of the home router. Consequently, detecting connected IoT devices from outside the home network is a difficult task.
Now this method has been devised to detect vulnerable and connected IoT devices before they are compromised by monitoring the data traffic of each smart home device. This allows telecommunications companies to verify whether specific IoT models, known to be vulnerable to exploitation by malware for network attacks, are connected. It helps telecommunications companies to identify possible threats to their networks and to take preventive measures quickly.
The idea is basically that a telecommunications company can detect vulnerable IoT devices that are connected behind a NAT and use that information to take action.
We already know that IoT devices can be a major danger to our security. They may have vulnerabilities that are exploited by cyber criminals and should be avoided.
