Organizations face mounting pressure from cyber threats that exploit detection delays. Industry data shows breach costs averaging $4.45 million per incident, with late detection driving exponential damage. Attackers typically operate undetected for 197 days, establishing deep network presence before discovery.
An indicator of compromise is digital evidence or a signal that a network or endpoint has been breached or that malicious activity has occurred.
Real-time indicators of compromise (IoCs) detection breaks this cycle. Immediate threat identification coupled with automated response substantially reduces business impact and operational disruption.
Understanding Indicators of Compromise in Threat Intelligence
IoCs represent digital evidence of malicious activity within organizational networks. These forensic artifacts appear in three distinct categories and help security teams identify security threats before they escalate into major security incidents.
Security professionals use threat intelligence to identify IOCs and mitigate potential threats before they escalate.
Network Traffic-Based Evidence
TypeCommon ExamplesBusiness Risk
Malicious IPsExternal command serversData theftSuspicious domainsPhishing infrastructureCredential lossTraffic patternsAbnormal network traffic flows Service disruption
Monitoring for malicious IP addresses, unusual domains, and suspicious activity involving domain name servers is essential for detecting threats within an organization’s network. By analyzing IP addresses, web traffic, and identifying network traffic anomalies or unusual network traffic—such as spikes or deviations from normal network traffic patterns—security teams can quickly spot indicators of compromise. These methods help uncover connections to a malicious IP address, detect access to an unusual domain, and reveal abnormal web traffic, all of which are critical for protecting the organization’s network from cyberattacks.
Host-Based Evidence
File signatures: Changed executables, malicious code, detection of malicious files and suspicious files, monitoring for file-based IOCs such as file hashes, filenames, and file paths, analysis of system files for unauthorized changes
System modifications: Registry alterations, configuration changes, monitoring registry keys and suspicious registry changes, reviewing registry configurations, tracking changes in system settings and system configurations, detection of unexpected software installations
Process behaviors: Unusual application activity, memory patterns, identification of suspicious processes, monitoring for host-based IOCs such as suspicious processes and file activities
Behavioral Evidence
User anomalies: Unexpected access patterns, privilege misuse, monitoring for behavioral IoCs, detection of suspicious behavior, identification of compromised accounts and unusual activity in user accounts, vigilance against insider threats, use of entity behavior analytics
Access requests and brute force attempts: Tracking unusual access requests, monitoring for brute force attempts involving repeated login failures or attempts from different locations
File and data requests: Detection of repeated requests for the same file or numerous requests, which may indicate data theft or malicious activity
Data movements: Unauthorized transfers, unusual volumes
Timing irregularities: Off-hours suspicious activity, impossible locations
Critical systems: Ensuring the protection of critical systems through access controls, monitoring, and incident response
Key Point: IoCs show attacks already occurred. Indicators of Attack (IoAs) predict future threats and help prevent data breach incidents.
Business Impact of Detection Speed
Traditional security models create substantial risk exposure:
Detection SpeedAverage Cost of BreachDowntimeData Loss
Slow (Days/Weeks)$3.86M21 daysHighFast (Minutes/Hours)$1.12M4 hoursLow
Faster detection not only reduces costs and downtime, but also improves incident response capabilities by enabling more effective incident response and targeted security measures.

Fidelis Elevate® XDR Platform Overview
Fidelis Elevate® consolidates multiple security functions into one platform. The system combines network traffic monitoring, endpoint protection, deception technology, and data protection capabilities. This unified approach eliminates tool sprawl while improving detection accuracy.
Fidelis Elevate® leverages advanced technological solutions, integrating with endpoint security platforms and threat intelligence platforms to enhance threat detection and response across diverse environments.
Platform Architecture
Asset Discovery Engine: Continuous network mapping identifies all connected devices across hybrid infrastructure. The system tracks managed and unmanaged assets, providing complete attack surface visibility. Risk profiling helps prioritize protection efforts.
Threat Correlation System: Advanced analytics connect threat indicators across multiple data sources. The platform incorporates intrusion detection systems, network monitoring tools, and log data analysis to identify and correlate threat indicators. The platform maps detected activities to MITRE ATT&CK framework, providing context for security decisions. External intelligence feeds enhance detection capabilities.
Deception Infrastructure: Distributed decoy systems create early warning networks throughout the environment. When attackers interact with fake assets, immediate alerts notify security teams. This approach provides additional detection layers.
Response Orchestration: Machine learning algorithms prioritize genuine threats from background noise. Automated workflows execute containment actions based on threat type and severity. Playbooks ensure consistent response procedures.
