What does IOC stand for in cybersecurity?

• A. Indications Of Compromise
• B. Initial Object Count
• C. Integrated Operating Channel
• D. Input Of Control

Answer: (D)

In cybersecurity, IOC stands for Indicators of Compromise. These are observable signs that a system or network may have been breached or is under attack. They guide detection and response by security teams, often feeding into SIEMs, EDRs, and threat intelligence programs. Examples include known malware file hashes, suspicious IP addresses or domains contacting a host, unusual file names, specific registry changes, or odd account activity. Because IOCs are concrete, observable artifacts that point to malicious activity, they’re the most appropriate way to describe what IOC stands for. The other phrases—Initial Object Count, Integrated Operating Channel, and Input Of Control—aren’t standard terms used to describe security-compromise indicators and don’t convey the same meaning.
