Think Positive Cyber

Today, I learned about hardware vulnerabilities in IoT (Internet of Things) devices while watching Hardware Vulnerabilities – CompTIA Security+ SY0-701 – 2.3. Many everyday devices—like smart thermostats, refrigerators, and security cameras—run on embedded Linux firmware, which often lacks regular security updates. Some devices use BusyBox, a lightweight Linux version, making them potential cybersecurity risks. I also learned how EOL (End of Life) and EOSL (End of Service Life) statuses impact security: manufacturers stop providing patches, leaving devices vulnerable to exploits. A real-world example is the Trane ComfortLink II thermostat, which had a major vulnerability in 2014, but took a full year to receive a patch. This highlights the importance of firmware updates, network segmentation, and secure configurations to mitigate IoT threats.

After watching the video, I logged into Notion to update my Kanban job board, adding cybersecurity job postings, including Security Systems Administrator and Information Security and Intelligence Intern roles at MTS. I also ensured my cover letters and resumes were aligned with each position’s requirements. Keeping my job applications organized is crucial for staying on top of deadlines and maximizing my opportunities in the cybersecurity field. Lastly, I worked on my blog at Think Positive Cyber, reinforcing my understanding of IoT security risks and industry best practices. This blend of learning, job searching, and hands-on practice is helping me stay focused and prepared for my Security+ certification and cybersecurity career.
