Study Notes
Network Devices
- A Router processes and forwards data packets based on the concept of a destination IP address.
- A Switch connects multiple devices to a network, increasing the speed of data transmission.
- A Hub connects all devices to a network, but is considered a compromised computer.
Security Threats
- A Denial of Service (DoS) Attack disrupts computer access to internet services.
- A Back Door is a set of instructions that allow users to bypass security controls.
- Spoofing is a technique intruders use to make their network or internet transmission appear legitimate.
- A Botnet is a group of compromised computers connected to a network.
Security Measures
- Firewall is a hardware or software that protects a network's resources from intrusion.
-
Measures to prevent unauthorized access include:
- Acceptable use policy
- Disabling file and printer sharing
- Firewalls
- Intrusion detection software
Access Control
- Access Control defines who can access a computer and what actions they can take.
