Runtime protection adds an active defensive layer while applications are serving real users, and CSSLP questions increasingly probe how these controls fit with design, testing, and operations. Core capabilities discussed here include web application firewalls and API gateways that enforce schemas, rate limits, and authentication requirements at the edge, along with runtime self-protection mechanisms embedded in applications. You learn how memory protections, container or workload sandboxes, and egress controls limit what an exploit can do even if a vulnerability is present. The episode also explains how behavior analytics across identities, sessions, and endpoints can highlight privilege misuse or lateral movement that static controls alone might miss.

Successfully integrating these defenses requires careful tuning and alignment with existing incident and monitoring processes. Examples cover deploying protections in stages, starting with monitor-only modes to understand traffic, then gradually moving to blocking configurations as confidence grows, all while watching key reliability metrics. Scenarios illustrate how deception points such as honey tokens or trap endpoints reveal attacker presence early without confusing normal operations, and how admission controls that validate signatures and provenance prevent untrusted code from entering the environment. You see how runtime protections should feed alerts into incident response runbooks, support dwell-time reduction metrics, and be adjusted when new threats or false positives appear. Exam-relevant options consistently favor approaches that treat runtime controls as part of a layered strategy tied to telemetry, testing, and governance, rather than as isolated appliances turned on without context or review.
