Failed attempt
Record unsuccessful authentication events collected from Windows.
What failed-login monitoring provides
Failed-login monitoring records unsuccessful Windows authentication events and makes them easier to review across monitored servers. The goal is visibility: identify which account was targeted, when attempts occurred and which source IP was recorded when available.
🧑
Target account
See which username was involved in the failed attempt.
🔎
Investigation context
Correlate timestamp and source IP with other operational events.
What the data can help you investigate
- Repeated attempts against an administrator account.
- Failed RDP access after a password change.
- Users attempting to connect to the wrong server.
- Unexpected attempts from a remote IP address.
- Authentication failures around the time of another incident.
Failed logins are a signal, not a verdict
A failed login can be caused by a typing error, an expired password, a saved credential, a service account problem or malicious activity. Context matters. Review the number of attempts, source, target account, time window and whether a successful login followed.
Current product scope: Vigilio records failed-login events for dashboard review. Dedicated Telegram alerts and automated brute-force blocking are not currently included.
Recommended Windows protections
Monitoring should be combined with preventive controls:
- Do not expose RDP directly to the internet when a VPN or gateway can be used.
- Enable MFA where the access architecture supports it.
- Use strong unique administrator passwords.
- Configure account lockout and audit policies carefully.
- Restrict access by firewall and source network.
- Keep Windows and endpoint protection updated.
How Vigilio fits into incident review
- Open the monitored Windows server in Vigilio.
- Review failed-login events around the incident time.
- Compare usernames, timestamps and source IP addresses.
- Check whether successful login events followed.
- Use native Windows logs or a SIEM for deeper forensic analysis when required.
Positioning: Vigilio is a lightweight operational visibility tool. It complements Windows Event Viewer and security controls but does not replace a centralized SIEM or endpoint detection platform.
