Not every organization has a SIEM — but that doesn’t mean you’re flying blind.
Here are three common Indicators of Compromise (IoCs) you can detect using tools you already have:
1. Unusual Process Behavior
Look for processes that:
- Spawn unexpectedly (e.g.,
powershell.exe launched from Word) - Run from temp folders or user profiles
- Use excessive CPU or memory
🛠 Tip: WithSecure Elements EPP logs can help you trace these anomalies.
2. Outbound Connections to Rare IPs
Unexpected outbound traffic to:
- IPs in countries you don’t do business with
- Domains with low reputation scores
🛠 Tip: Use your firewall or endpoint logs to flag these.
3. User Account Anomalies
- Logins at odd hours
- Multiple failed login attempts
- Privilege escalation without justification
🛠 Tip: WithSecure Elements EDR behavioral analytics can surface these patterns.
🔍 You don’t need a SIEM to start detecting threats. You just need visibility — and the right questions.
