In this first lecture, we’ll cover the basics of cybersecurity, its importance, types of threats, and key principles.  Information Security (InfoSec) Information Security (InfoSec) focuses on protecting all types of information, whether in digital, physical, or intellectual form, from unauthorized access, misuse, destruction, or alteration. Its goal is to preserve the confidentiality, integrity, and availability (CIA) of information. Main Focus: InfoSec encompasses both physical security (e.g., protecting server rooms, locking file cabinets) and technical security (e.g., encryption, access controls).  Cyber Security Cybersecurity is a subset of information security, but it focuses specifically on protecting digital systems and data from cyberattacks. It involves securing computers, networks, servers, and data from breaches, hacks, or malicious attacks that occur in the digital realm. Information Security Vs. Cyber Security Key Differences  What is Cyber Security? Cyber Security involves implementing measures to defend against threats to systems, networks, and information. These threats can come from various sources, including cybercriminals, hackers, or even accidental errors by users. The main goals of cyber Security are: Information Security Triad Availability: Ensuring that systems and data are available for use when needed. Information Security Stages  Technologies Security Assessment Information Security Domains Cyber Security Jobs  Course Outlines What is Information Security Understanding Security Terms and principles (CIA) Security Technologies Types of threat actor Understanding Hacking Methodologies Security Assessment Techniques Types of Malwares Type of Attacks Cryptography Firewalls Database Security Wi-Fi Security Secure Protocols Web Application Security  Classwork Quiz 1: week 5 (5 marks) Assignments and researches (5 marks) Quiz 2: week 12 (5 marks) Midterm: week 8 (20 marks) Lab: week 14 (3 tasks) (15 marks) Final exam: week 16 (50 marks)  Resources Books: o Introduction to Cyber Security: Fundamentals o Hacking: A Beginners’ Guide to Computer Hacking, Basic Security, And Penetration Testing o Hacking: The Art Of Exploitation Lectures Presentations Videos  Conclusion Cybersecurity is an essential part of the modern digital world.
