Indicator of Attack Definition: An Indicator of Attack (IOA) is a sign or signal that suggests an ongoing or attempted compromise of a system or network by malicious actors.
An Indicator of Attack (IOA) is evidence that suggests malicious activity or an ongoing cyber intrusion within a network or system. IOAs are typically derived from abnormal behaviors or patterns that may indicate a security incident, such as unusual network traffic, unauthorized access attempts, or unexpected system modifications. Security analysts use IOAs to detect, investigate, and respond to potential cyber threats and attacks effectively.
