Introduction
We live in a world where everything is connected. The days when only one computer at home or office was connected to the Internet are long gone. Today, networks of connected devices are everywhere, all connected to the World Wide Web of the Internet, also known today as the Cloud. And then, there is the Internet of Things (IoT). Our homes and offices are full of devices connecting to our networks and the Internet, accessing various Cloud software providers. With so many connected devices, knowing what lurks undetected on your network is challenging. We will explore the possibilities of malware, data theft, and unauthorized access, emphasizing the need for device identification and monitoring.
Risks of IoTs
In the race to offer innovative cloud-connected services, many hardware and appliance manufacturers eager to enter the Internet of Things market may lack sufficient expertise in cybersecurity. This inexperience can lead to vulnerabilities in smart devices, making them more susceptible to compromise by criminal hackers. IoT devices that are rushed to market without rigorous security testing may be exploited.
A striking example of this vulnerability was demonstrated when researchers discovered that a refrigerator was part of a botnet responsible for sending out spam emails. This incident, as reported by Proofpoint, highlighted a significant compromise of IoT devices, where over 750,000 spam emails were sent from more than 100,000 home networking devices, multimedia centers, televisions, and at least one refrigerator. It is important to understand how many IoT devices are connected to your network and whether they are secure.
Risks of unidentified devices
Unidentified devices connected to your network can be susceptible to malware infections, as they may lack proper security measures or have outdated firmware. Malicious actors can exploit such devices to gain entry to your network and launch attacks that may compromise your data and systems.
To enhance the security of your network, it is crucial to identify and monitor all connected devices. By monitoring your network and detecting unexpected changes promptly, you can quickly mitigate potential issues and prevent potential security breaches.
Risks of Wireless networks
Wireless networks, while offering convenience, are susceptible to various security risks. Unauthorized access is a common concern, where neighbors (at home or work), or strangers in a parked car could connect to your network. This unauthorized use slows down your internet speed and leads to bandwidth theft. Another serious risk involves cybercriminals monitoring your activities and stealing sensitive information, which can happen if your network security is compromised. It can lead to identity theft and financial losses. Furthermore, there’s the danger of your network being used for criminal activities, such as illegal downloads or hosting illicit content. In such cases, you could unknowingly become subject to investigation for crimes you did not commit, as your network becomes a tool in the hands of cybercriminals.
Conclusion
It is important to be aware of the potential dangers that unidentified devices on your network may pose. Malware infections, data theft, and unauthorized access are just some of the risks associated with these devices. To protect your data and systems from potential harm, it is crucial to implement continuous monitoring of your network and to receive alerts of any changes. This way, you can identify and take action against any potential threats.
