LDAP Injection

Definitions

1. LDAP Injection is an attack technique in which an adversary alters directory queries by inserting untrusted input into LDAP filters or attributes. 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: LDAP 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 LDAP 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."
