Cybersecurity for Absolute Beginners: OS Security (Udemy.com)

LEARN OPERATING SYSTEM SECURITY FROM ONE OF UDEMY'S TOP IT INSTRUCTORS

Your computer contains your most sensitive data: financial records, personal photos, business documents, passwords, and private communications. Yet most people rely on basic antivirus software without understanding the powerful security features already built into Windows and Mac.

Every unencrypted hard drive is one laptop theft away from total data exposure. Every misconfigured user account is a vulnerability waiting to be exploited. Every system without proper backups is one ransomware attack away from permanent data loss.

This comprehensive course teaches you how to secure your Windows or Mac computer using built-in operating system features. No expensive third-party software required. Designed specifically for absolute beginners with step-by-step demonstrations for both platforms.

WHAT MAKES THIS COURSE DIFFERENT: 35+ LIVE DEMONSTRATIONS FOR WINDOWS AND MAC

Unlike courses that only lecture about operating system security concepts, this course shows you exactly how to implement security measures through extensive live demonstrations on both Windows 10 and Mac.

You'll watch step-by-step demonstrations of BitLocker and FileVault disk encryption, see how to configure NTFS and Mac file permissions, learn to set up Windows Firewall and Mac Firewall rules, implement Time Machine and Windows System Image backups, configure Windows Defender and Mac XProtect antivirus, and harden your operating system through UAC, AppLocker, and Gatekeeper configurations.

This isn't just PowerPoint lectures. This is hands-on training showing you how to leverage the powerful security tools already included in your operating system.

This is Part 3 of the Cybersecurity for Absolute Beginners series. While Parts 1 and 2 cover essential concepts and online privacy, Part 3 focuses specifically on securing your Windows or Mac computer at the operating system level. Earlier courses are helpful but not required. This course can stand alone.

WHAT STUDENTS ARE SAYING

"Thanks Alton for the excellent course. The course is very useful as it provides lots of information on the built-in features in the OS that can reduce cybersecurity risks and better protect our own data. I believe any individuals or small business owners who only have limited financial resources or computer-related knowledge should be able to benefit from the course by adopting the recommended measures or changes in the OS settings to improve cybersecurity." — Maggie ★★★★★

"Course was very easy to follow and provided an excellent overview of Operating Systems and best practices to secure them." — Michael ★★★★★

"Another banger by Alton. I've learned so much in this course I'm looking forward to the next one" — Andrea ★★★★★
