Why This Matters
You need attack-flow thinking to design practical defense layers.
Confusion Busters
Common confusion: Firewall alone is enough
Fix: Modern defense needs layered controls: filtering, detection, response, and segmentation.
Common confusion: DDoS only at app layer
Fix: DDoS can be volumetric, protocol-level, or app-level.
Attack Flows
- ▸DDoS floods target resources and saturates edge links.
- ▸MITM intercepts traffic path to observe or alter communication.
- ▸Spoofing forges identity fields like ARP/IP/DNS sources.
Common Network Attack Flows
DDoS — Botnet to Target Flood
MITM — Victim Through Attacker to Server
Spoofing — Forged Source to Bypass
Defense Architecture
- ▸Rate limiting, scrubbing, and CDN edge absorb floods.
- ▸TLS, segmentation, and anti-spoofing policies reduce exploitation.
- ▸SOC detection + response playbooks close feedback loop.
Layered Defense Architecture
IPS — Inline Block
IDS — Detect & Alert
Firewall — Policy Control
VLAN — Segment & Isolate
VPN — Encrypted Tunnel
