Need of Embedded Cybersecurity for Business Organizations

Through this article, we will gain in-depth knowledge as to why there is a growing demand of embedded cybersecurity for business organizations. Every device, from smart automotive to microwave ovens, is run by embedded systems. Our lives are being made easier by operational innovations powered by embedded systems.

At the same time, cyberattacks on embedded devices are growing at a rapid pace. Hence, embedded cybersecurity becomes essential because hackers may easily access the data that embedded devices generate, process, and communicate.

Different Forms of Cyberattacks on Embedded Systems

Embedded systems are a common tool used by businesses in daily operations. To avoid cyberattacks against embedded systems, all business organizations must give priority to embedded cybersecurity. The embedded systems in the gadgets and appliances are directly connected to the organization’s main network.

A breach therefore won’t just affect the embedded system. The entire network will go down as a result. Embedded systems are vulnerable to a variety of attacks due to the number of potential vulnerabilities.

Let’s examine a few of the most prevalent ones.

1) Software Based Cyberattacks –

The main application that controls the device is the target of these attacks. A hacker can access the device’s internal data and take over control. Software-based attacks don’t need a hacker to have any specialized skills. Additionally, they can be remotely executed by attackers.

The following are a few software-based cyberattacks against embedded systems: –

A) Malware Attacks – In this form of software-based cyberattack, malicious code is used by hackers to intercept app data and launch attacks using malware. As with other systems, it has an impact on embedded systems. Malware is typically distributed by attackers via fictitious drivers, security patches, or firmware updates. The victim can lose control over the embedded systems during the execution of the malware attack and can also lose access of all his/her important data stored in embedded systems.

B) Brute Force Attacks – In this form of software-based cyberattack, it involves speculation about the embedded systems in order to get access to its valid credentials. Most embedded systems and devices include a graphical user interface, which hackers frequently take advantage off. To stop brute force attacks, businesses must use secure passwords that are difficult to guess. One piece of advice is to restrict login attempts.

C) Memory Buffer Overflow – Hackers saturate the device’s memory in this form of cyberattack by taking advantage of system weaknesses. The memory buffer designated to hold the moving data inside embedded devices is manually filled by attackers. The embedded system’s operating system will try to save some information in the memory area close to the buffer. However, it will inevitably crash.

2) Network Based Cyberattacks –

These attacks are started by hackers who take advantage of vulnerabilities in the network infrastructure of the target. Attackers are able to track and snoop on any network communication sent to or from embedded systems thanks to these hacks.

The following are a few network-based cyberattacks against embedded systems: –

A) Man-In-The-Middle Attacks: In this form of network-based cyberattack, the attacker places themselves in the path of the data transmission, where they can intercept or change it. Hackers attach a third device between two others by taking advantage of the vulnerabilities in the connection between the two. Then, in an effort to eavesdrop, they try to gain access to the encryption key used by both devices.

B) DNS Poisoning Attacks: In this form of network-based cyberattack, to redirect from the targeted website to another one, attackers take advantage of the DNS server’s flaws. The following attacks are some others that enterprises should be aware of in addition to these significant network-based attacks including Distributed Denial of Service (DDoS) Attacks and signal interference during sessions.

3) Side Channel Cyberattacks –

These are the kind of attacks that take use of hardware security vulnerabilities. It is the most difficult to carry out and therefore the most expensive for the victims. It is challenging for embedded cybersecurity professionals to mitigate the side-channel attacks.

The following are a few side channel cyberattacks against embedded systems: –

A) Power Attacks: By physically gaining access to an embedded system, this attack is being planned. The internal connections are probed by hackers, who look for variations in power usage.

B) Timing Attacks: The time of embedded system operations is taken into account when these kinds of attacks are prepared. Hackers must have access to the device physically as well as a thorough understanding of the embedded system’s design and its overall architecture.

C) Electromagnetic Attacks: Hackers examine device emissions using electromagnetic signals during these kinds of attacks. It is used by them to decode cryptographic procedures and even obtain hidden keys.

Cybersecurity Measures for Embedded Systems

For business organizations looking to safeguard their embedded systems from hacking may consider the following cybersecurity measures: –

1) Always use strong cryptographic keys to secure your sensitive data and apps.

2) Ensure a secure boot while starting your embedded systems.

3) Keep unauthorized software access out of the picture.

4) Never overlook isolation methods or configuration errors.

5) To minimize your attack surface, speak with an embedded cybersecurity specialist.

The Conclusion

Hence, from the above discussion we can conclude this article by saying that everyone is susceptible to cyberattacks, including embedded systems both in terms of software and hardware. Companies require strong hardware and software configurations in order to enhance cybersecurity for embedded systems. To protect your embedded systems from cyberattacks, think about consulting a professional rather than doing it yourself.
