Course description

In this course for the CompTIA A+ 1001-1002 exam, we'll take a look at Viruses, Trojans, worms, and distributed denial of service attacks which are some of the most significant threats in networking. Next, we'll explore these and other threats and vulnerabilities, including the basic security of file and folder permissions. Finally, we'll learn the basics of user authentication and extended security through the use of encryption such as EFS and bit locker.

Each LearnNowOnline training course is made up of Modules (typically an hour in length). Within each module there are Topics (typically 15-30 minutes each) and Subtopics (typically 2-5 minutes each). There is a Post Exam for each Module that must be passed with a score of 70% or higher to successfully and fully complete the course.
