Studying for exam pc 1189

Please help me study for an exam. This exam is about network security. The class's text book is this: Stallings, W. & Brown, L. (2023). Computer security: Principles and practice (5th Ed.). Upper Saddle River, NJ: Prentice Hall. ISBN13: 9780138091712

If you are not able to view the text book try to find a different version you can view. The chapters this will be covering are 1 to 6. The subjects for this exam are Security Fundamentals, cryptographic tools, internet security protocol and standards, User authentication, access controls, database security, and malicious software. I believe the easy question on the exam is about how a client connects to a server, so try to go into detail about that.
