Command Injection

Noun · Security & Infosec

Definitions

  1. Command Injection is an attack technique in which an adversary causes an application to execute attacker-controlled operating-system commands. Defenders analyze it to understand prerequisites, affected trust boundaries, and likely telemetry, then reduce risk with layered controls such as validation, hardening, rate limits, segmentation, and high-quality logging for investigation and response.

    In plain English: Command Injection is a way attackers abuse systems or trust relationships, and defenders counter it with better design, validation, monitoring, and layered controls.

    Example: "During the assessment, the team simulated Command Injection against a staging service, confirmed the weakness with logs and telemetry, and then added tighter validation, safer defaults, and monitoring so the same technique would trigger an alert in production."
