Integer Overflow

Definitions

1. Integer Overflow is an attack technique in which an adversary causes arithmetic wraparound that breaks bounds checks, allocations, or logic. 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: Integer Overflow 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 Integer Overflow 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."
