What is Data Poisoning in Applied AI?
An attack where the adversary injects malicious examples into the training data to change the model's behavior at inference time. Targeted poisoning makes specific inputs misclassify; backdoor poisoning installs a trigger that activates a hidden behavior. The MITRE ATLAS taxonomy treats data poisoning as a first-class technique.
Why Data Poisoning Matters for Your AI or Cybersecurity Career
Any team that trains on user-generated, scraped, or vendor-supplied data must defend against poisoning. AI security and AI governance roles design those defenses.
