CS Network Attacks
This lesson is part of Cyber Security · All levels
Summary
Network attacks are intended to disrupt availability, steal data, or gain unauthorized access through network protocols and devices. Common examples are Denial of Service (DoS), Man-in-the-Middle, ARP spoofing, and DNS spoofing. Understanding how it works helps the admin choose the right mitigation such as encryption, segmentation, and traffic monitoring.
Key points
- DoS/DDoS flood targets with traffic so that the service does not serve normal users.
- Man-in-the-Middle intercepted or modified two-way communication.
- ARP spoofing directs victim traffic to the attack engine via a fake ARP package.
- DNS spoofing leads users to malicious sites through fake DNS data.
- Mitigation: encryption (HTTPS/VPN), certificate validation, and monitoring of traffic anomalies.
