In the era of the Internet of Things (IoT), which is rapidly evolving, digital security becomes paramount. Whether we like it or not, everyone must be ready to face this development. If individuals are already using IoT-concept devices, they must understand the basic concepts. Why? Let's discuss together about digital security in this Internet of Things, something we've actually been doing and using in our daily lives, both inside and outside our homes. Yet, we may not realize that some of our activities are already related to IoT! If we are connected to IoT but unaware that we're using this system, we're actually in danger, especially concerning digital security, without realizing it. So, how do we address digital security, especially in the Internet of Things? And what exactly is the Internet of Things?
What is the Internet of Things (IoT)?
The Internet of Things (IoT) is a network of physical devices connected to the internet, enabling them to communicate and exchange data. Examples of IoT devices include sensors, cameras, connected vehicles, and smart home devices.
Examples of Problems in the Internet of Things
Some common security issues that arise in IoT include:
DDoS Attacks: Attackers use IoT botnets to launch massive DDoS attacks against websites or online services.
Data Theft: Insecure IoT devices can be targeted for the theft of personal or business data.
Control Takeover: Attackers can take control of IoT devices for malicious purposes or to steal information.
What are IoT Security Suites?
IoT Security Suites are a collection of security solutions designed specifically to protect IoT devices and infrastructure from various cyber threats. These include functions such as threat detection, data encryption, access management, and security monitoring.
The world of technology, unbeknownst to us, is already interconnected through the Internet of Things (IoT), where various internet-connected devices can communicate and exchange data automatically. However, in this data exchange, many of us unwittingly overlook the digital security we employ in each data exchange process. A simple example of data exchange is using Bluetooth in wearable devices like wireless headphones, earbuds, or smartwatches to transfer data or receive commands from smartphones or other devices. In using these devices, we inadvertently disclose security systems ourselves. Whereas, on a larger scale, the use of CCTV in public spaces or on roads can be considered part of the Internet of Things (IoT) and can be included in the concept of IoT Security Suites as part of its security system.
CCTV in public spaces is often connected to the internet to allow remote monitoring and data-driven decision-making. They can be programmed to send real-time video data or stored on servers accessible via the internet. From here, the data security of CCTV can be exposed to the public and its data deleted, making it unknown to the public.
What is Digital Security?
Digital security encompasses practices and technologies designed to protect data, devices, and infrastructure from cyber threats. Practices or actions in this security system involve protection against unauthorized access, data theft, information manipulation, and other service disruptions.
Therefore, with the increasing development of technology and the internet, at least the activities we conduct in various aspects using the internet or other wireless networks, we are already prepared with the data protection we have. For example, in internet networks, we often use social media. One simple step we need to take to stay safe is to update these internet applications. And this is the only reason why application developers like TikTok or Instagram always update to ensure users stay safe using their applications. Furthermore, as active internet users, you should at least update applications and provide sufficient security system applications such as antivirus or anti-malware.
Examples of Digital Security
In addition to the examples mentioned above, here are some examples of digital security that you must know and then implement on mobile devices or internet service accounts you use:
Data Encryption: Protecting data by converting it into a format that cannot be read without an encryption key.
Two-Factor Authentication: Requiring two different verification methods to access an account or device.
Software Updates: Installing the latest software updates to fix known security vulnerabilities.
Firewalls: Monitoring and controlling network traffic to prevent unauthorized access.
Intrusion Detection Systems (IDS): Detecting suspicious activity or security threats within the network.
How to Address Digital Security
Whatever we use, from mobile devices to the most advanced devices, as long as it falls under the IoT system concept, we must take several steps to address digital security in the context of IoT, including:
- Regularly updating software to fix security vulnerabilities.
- Using strong passwords and two-factor authentication to protect access to IoT devices.
- Implementing security solutions such as firewalls and IDS to monitor and protect the network.
- Actively monitoring network activity and responding quickly to detected threats.
- Using IoT Security Suites to provide comprehensive security protection for IoT devices.
By taking these steps, we are at least preparing ourselves and staying vigilant in our daily activities, whether it's using phones for various activities, vehicles, or digital accessories. Digital security in the Internet of Things (IoT) is a crucial aspect that must be taken seriously. By recognizing potential threats and taking appropriate steps to protect IoT infrastructure, we can safeguard our data safely and easily. Hope this helps.
