Security in IoT: Should We Be Concerned About the Internet of Things?

The world is increasingly digital, and while this statement is often repeated to the point of becoming a cliché, it is indeed true. In this context, it is important to discuss more complex issues, such as IoT security.

But after all, do you know what IoT is? Even though it's not a widely known term, the Internet of Things (IoT) is present in the vast majority of companies and many households with internet access in Brazil.

The Internet of Things refers to a network of physical objects embedded with sensors, software, and other technologies that enable them to communicate and interact when connected to the internet.

This communication and synchronization between devices offer greater convenience, as these processes are carried out automatically. However, as with any other technology sector, the more open and convenient the system, the greater the risks.

Where is the Internet of Things Present? Before understanding the importance of IoT security, it’s crucial to know where you can find devices that fall under this technology in everyday life.

According to data from the German data company Statista, in 2021 there were approximately 11.3 billion IoT devices worldwide. The same research suggests that by 2023, this number could exceed 15 billion.

So, with this information, it's clear that this technology is already present in various aspects of daily life, right?

IoT devices can be found in synchronized company computers, mobile phones, and even household appliances like refrigerators, washing machines, and coffee makers.

It's also common to find IoT in equipment such as door controls, locks, thermostats, lighting systems, and other technologies frequently used in factories or offices.

It's worth noting that the Internet of Things is part of the Symbiotic Web, also known as Web 4.0, which aims to integrate the internet into people's daily lives, making life more online and efficient.

The Importance of IoT Security Most people want to bring conveniences to their daily lives and have a smart home with synchronized devices.

However, with the increase in IoT devices, it is expected that there will be an increase in risks and greater security vulnerabilities.

Many of these devices lack cybersecurity features, even the more sophisticated ones. This increases the number of cybercrime cases. Major risks include:

• Device Intrusion for Fraud: Many cybercriminals find ways to breach security systems or open gates and entrances, safes, etc., leading to various fraud and theft incidents.
• Data Theft: Another imminent danger is the theft of user data stored on IoT devices. Cybercriminals might access bank accounts, sell user information to companies, and commit other crimes.
• Malware: Cybercriminals often manage to crack passwords of poorly protected IoT devices, infecting them with malware. This can lead to access to confidential information, fraud, and various types of theft.

Understanding these possibilities makes it easier to see the importance of implementing and investing in IoT security for both company and personal devices.

Remember that all devices, even those that seem harmless, can suffer cyberattacks. Identifying vulnerabilities and implementing protection strategies can provide both cost savings and security for your daily operations.

Methods of Protection and Security in IoT Now, just because you have discovered all the dangers associated with IoT devices doesn’t mean you should forgo technological advancements! After all, that's why IoT security exists.

Protection methods are evolving to ensure that daily life is more technologically advanced, convenient, and secure.

Here are some methods to ensure greater protection for your IoT devices:

• Device Control: It's crucial that all your devices have strong passwords. The simpler the passwords, the easier it is for cybercriminals to breach them. Additionally, any device should be locked if stolen. A good control tactic is to log out of company accounts and profiles after work, which reduces the risk of unauthorized access to sensitive information.
• Software Updates: Regular updates bring more protection to your devices. Always install new updates as soon as they are available. Cybercriminals update their methods and programs, so outdated software can create vulnerabilities.
• Disable Unused Features: Devices often come with various features that can facilitate your daily life. Only keep active those you actually use. This helps save battery and reduces the resources available for potential unauthorized access.
• Preemptive Vulnerability Identification with Bug Bounty: A growing trend among large companies is investing in Bug Bounty programs. This rewards individuals who identify potential vulnerabilities in systems, such as lack of security in IoT devices. In Bug Bounty programs, information security experts analyze your company's systems for weaknesses that could facilitate cybercriminal activity.
