Cyber threats are growing smarter and more frequent, making early detection critical for protecting your business. One of the most reliable ways to spot a cyberattack in its early stages is by tracking Indicators of Compromise (IOCs).
At AGAN Cyber Security LLC, we help businesses across Dubai identify and respond to security threats before they cause serious damage.
What Are IOCs?
Indicators of Compromise are digital traces left behind by cyber attackers. These clues can point to malicious activity within your systems—such as unauthorized access, malware, or data theft.
Some common IOCs include:
- Unusual spikes in network traffic
- Suspicious login attempts
- Malicious file hashes or executables
- Unexpected system changes
- Communication with known malicious IPs or domains
Spotting these signs early helps businesses contain threats quickly and reduce the risk of widespread impact.
Key Benefits:
- Early Detection of hidden threats
- Faster Incident Response to limit damage
- Better Forensics for understanding how the breach happened
- Regulatory Compliance support
- Stronger Security Posture through proactive defense
Why Should You Care About IOCs?
IOCs act like an early warning system, giving your IT or security team the chance to detect and respond to cyber threats before they escalate.
Types of IOCs Every Business Should Monitor
1. Network-Based IOCs
- Irregular data transfers
- Communication with suspicious IPs
- High traffic during off-hours
2. File-Based IOCs
- Unknown or unapproved files appearing
- Malware signatures detected
- Files being altered without explanation
3. System Behavior IOCs
- Creation of unauthorized user accounts
- Sudden permission changes
- High CPU or memory usage
4. Log-Based IOCs
- Multiple login failures
- Access from strange locations
- Missing or disabled security logs
