This article explains why truly understanding networking — not just memorizing definitions — is essential for cybersecurity and for passing interviews. It covers seven core topics and ties each to concrete attack techniques and defensive limits, using examples like SYN flood and ARP poisoning #SYNflood #ARPpoisoning
Keypoints
- Understanding networking is more important than memorizing acronyms when defending real systems.
- Explain TCP’s three-way handshake and how SYN flood attacks exploit it.
- Differentiate TCP and UDP and how each can be abused, such as DNS amplification via UDP.
- Subnetting and segmentation limit attacker lateral movement and enforce least privilege.
- Know the capabilities and blind spots of controls like firewalls, IDS, and IPS.
