Episode 50 — Counter DDoS, Man-in-the-Middle, and Poisoning Attacks
Network attacks often exploit trust and scale, and the SSCP exam assesses how well you can neutralize them. This episode explains the mechanics of Distributed Denial of Service (DDoS), man-in-the-middle (MITM), and poisoning attacks like ARP, DNS, and cache corruption. We describe volumetric versus application-layer DDoS, active interception through rogue gateways or compromised certificates, and data manipulation via falsified records. You’ll learn to align countermeasures—rate limiting, filtering, authentication, encryption, and validation—with each attack type, ensuring defense without crippling legitimate traffic.
Practical defense scenarios reinforce the logic. For DDoS, examples include upstream filtering by ISPs, content delivery networks absorbing load, and local rate limits that protect bandwidth. Against MITM, we discuss enforcing TLS with certificate validation, using secure VPN tunnels, and monitoring for certificate anomalies. For poisoning threats, we outline static ARP entries in critical segments, DNSSEC validation, and cache hygiene routines. Troubleshooting topics include identifying reflection amplifiers, tuning thresholds to avoid self-inflicted denial, and responding to certificate warnings properly. Mastering these countermeasures prepares you for exam items that test both recognition of the attack type and selection of the most effective, least disruptive mitigation step.
