- The Internet of Things connects billions of physical devices, from home security systems and traffic lights to the internet, creating significant cybersecurity challenges around data protection, privacy and network safety.
- Consequences of an IoT breach can range from identity theft to disruption of critical infrastructure like water and power systems.
- Effective IoT security relies on regular security assessments, strong device authentication, updated software and access to skilled cybersecurity professionals who understand modern risk mitigation.
- As IoT expands, federal agencies like CISA have emphasized that cybersecurity efforts must grow faster than the national dependence on connected devices.
- A career in IoT cybersecurity requires a blend of hard skills such as programming, data analysis and cloud implementation alongside soft skills like adaptability, communication and leadership.
What Is the Internet of Things?
What do your home security system, fitness tracker, vehicle GPS and local traffic lights have in common? They all contain devices that are part of the Internet of Things (IoT).
This network brings together physical objects, critical infrastructure and IT devices that contain sensors, software and other modern technology, allowing them to exchange data over the internet.
IoT holds significant promise; The National Institute of Standards and Economy went so far as to publish that it “could revolutionize the American economy by enabling a fully connected world with on-demand access to data, systems, and each other.”
In simpler terms, IoT is how everyday objects access the internet and communicate with each other and with humans. As you can imagine, this comes with extreme security concerns, which is why IoT and cybersecurity are often discussed together.
As more devices become connected, challenges around privacy, security and data management also arise. Ensuring the protection of sensitive information and implementing solid security measures are crucial aspects of this discussion.

Cybersecurity and the Internet of Things
Technology like IoT has made cybersecurity more valuable today than any other time in history. The following are important cybersecurity considerations surrounding IoT:
- Data protection
Hackers across the world are using malware, phishing, ransomware and more to attack valuable systems, including an estimated 15 billion IoT devices as of 2020. Depending on the device, data contained within each could put individuals or critical infrastructure at risk. Consequences range from identity theft to interruption of delivery systems that provide water and electricity. - Network safety
As network connections are integrated into widespread infrastructure, the Cyber Security & Infrastructure Security Agency has developed strategies for addressing IoT threats. Federal officials warn that it is crucial for cybersecurity efforts to grow faster than our national dependence. Stakeholders are encouraged to consider:- Evaluating security settings
- Ensuring you have updated software
- Connecting carefully
- Using strong passwords
- Risk mitigation
Some of the best ways to mitigate IoT cybersecurity threats are with regular security assessments, strong device authentication and access to cybersecurity experts with up-to-date education. Companies are investing in professionals who are able to understand risk and mitigation challenges, adjust policies and processes and implement the strongest modern practices.
Establishing Your Cybersecurity Career
To be successful in cybersecurity and IoT, you will need to cultivate certain hard and soft skills that will enable you to take on challenges in a fast-paced work environment.
Hard skills, or specific technical capabilities, in this instance include:
- An understanding of fundamental technology (i.e. programming languages, network configuration and firewall installation)
- Data analysis
- Cloud implementation
- Technical troubleshooting abilities
Soft skills, or personal attributes, that are useful in cybersecurity work are:
- Adaptability
- Communication skills
- Time management
- Leadership qualities
In order to build these skills and more, explore the University of San Diego’s 100% online programs to become a Master of Cyber Security Operations and Leadership or Master of Science in Cyber Security Engineering. Bachelor-prepared students are ideal candidates for this advanced degree, focusing on state-of-the-art techniques to defend against the latest cyber threats in either the public or private sector.
A worldwide effort to enhance cybersecurity has created lucrative employment opportunities for candidates with the right skills, experience and education.

frequently asked questions
Why are IoT devices harder to secure than computers?
IoT devices are harder to secure than computers because many were not designed with security as a primary consideration. Many ship with default passwords, limited update mechanisms and few interfaces for configuring security protections. They often run for a decade or more on firmware the manufacturer stopped supporting years earlier, and limited processing power can make it difficult to implement the same encryption standards used elsewhere on a network.
What are the most common IoT security vulnerabilities?
The most common IoT security vulnerabilities are weak or default credentials, hardcoded passwords, unpatched firmware, unencrypted data transmission and unnecessary open network services. Weak or absent device authentication can let attackers impersonate legitimate hardware. Insecure companion mobile apps and cloud APIs add further exposure, since compromising the service that manages a device can provide more access than attacking the device itself.
How can you secure the IoT devices on your home network?
You can secure the IoT devices on your home network with a few concrete steps. Change every default password and enable multi-factor authentication where it is available. Put smart devices on a separate guest network so a compromised device cannot reach computers holding sensitive files. Enable automatic firmware updates; disable remote access and universal plug and play unless you need them; and retire devices the manufacturer no longer supports.
What is the U.S. Cyber Trust Mark?
The U.S. Cyber Trust Mark is a voluntary federal labeling program for consumer IoT products established by the Federal Communications Commission (FCC) in 2024. Products that meet baseline cybersecurity requirements can display the label with a QR code linking to additional security information. The program is designed to help consumers identify devices that meet recognized cybersecurity standards.
What is the difference between IoT security and OT security?
The difference between IoT security and OT security is primarily the type of systems they protect and the consequences of failure. IoT security protects connected consumer and enterprise devices, where a breach often exposes data or provides unauthorized access. Operational technology (OT) security protects industrial control systems running power grids, water treatment facilities and manufacturing lines, where a breach can cause physical damage or disrupt critical operations. OT systems also often remain in use for far longer than traditional IT systems, including equipment that predates modern cybersecurity practices.
What jobs focus on IoT security?
Jobs focused on IoT security include IoT security engineer, embedded systems security engineer, product security engineer and operational technology (OT) or industrial control systems (ICS) security analyst. Hardware-adjacent specialties such as firmware analysis and embedded penetration testing also fall within this area. The work draws on networking and security fundamentals, along with familiarity with embedded systems and industrial protocols, which is a less common combination than general cybersecurity expertise.
