Key Terms in Cybersecurity
- Threat: Anything that can cause harm to systems or data (e.g., hackers, viruses).
- Vulnerability: A weakness in a system that can be exploited.
- Malware: Malicious software like viruses, ransomware, or spyware.
- Phishing: An attack using fake emails or websites to trick people into giving out information.
- Firewall: A security system controlling incoming and outgoing network traffic.
- Two-Factor Authentication (2FA): Security that uses two forms of identification to access an account.
- Antivirus Software: Programs that detect and remove malicious software.
- Hacker: Someone gaining unauthorized access to data or systems.
- Patch: A software update designed to fix bugs or vulnerabilities.
Need for Cybersecurity
- Protects personal data like passwords and bank information from hackers.
- Prevents identity theft by cybercriminals.
- Keeps businesses safe by protecting financial and customer data.
- Supports national security by protecting government infrastructure and citizens.
- Ensures safe online activity for browsing, shopping, and communication.
Roles in Cybersecurity

What is a Network
- A network includes two or more computers or devices (phones, printers, servers) connected to share data and communicate.
Components of a Network
- Router: Directs traffic between devices and connects a network to the internet.
- Switch: Connects multiple devices inside a local network to help them communicate.
- Hub: Connects multiple computers in a network, but sends data to all devices (less secure than switches).
- Network Cable (Ethernet): Physical cables that connect devices in wired networks.
- Server: A powerful computer that stores files, manages access, or runs applications for other computers on the network.
Network Topology
- Network topology is the layout of how a network communicates with different devices
Types of Topology
- Star Topology
- Bus Topology
- Ring Topology
- Mesh Topology
- Hybrid Topology
- Point to Point
- Point to multipoint
