Indicator of Attack (IOA) is a type of system that helps to detect malicious activity from hackers, cyber attackers, and malicious software. It works by looking for patterns in computer system log files from which it can derive suspicious behaviors. It is a valuable tool for identifying threats from both external and internal sources. IOA can be used to detect malicious activity in real time, as well as prevent further harm to the system.
IOA systems are typically run by IT personnel, though some can be used by non-technical personnel as well. These systems use analytics to look through system information such as application logs, network protocols, file system data, and application events for patterns that indicate malicious activity. Based on the pattern and context, an IOA system can detect the origins of an attack, its steps or functions, and any command or script that might have been used to execute the attack.
IOA can be used to detect different kinds of threats. It can monitor for malware, ransomware, phishing attacks, malicious actors, and more. It can also help in the investigation of attacks, as well as act as an early warning system that can alert personnel when an attack is likely to occur.
Overall, IOA can be an effective tool for both IT professionals and non-technical personnel to detect, investigate, and prevent malicious activity. It can provide a valuable layer of protection to any computer system and help to bolster the security of it.
