01The Windows events that matter
✓What you will learn
- Know the core Security event IDs and what each proves
- Read logon types and 4625 status codes to separate spraying from typos
- Spot Kerberoasting in 4769 and abuse in 4688 command lines
- Read Entra ID and Okta sign-in logs for spraying, token theft and MFA abuse
Windows logs thousands of event IDs. An analyst needs about fifteen. Learn what each one proves and, just as important, where it is logged: on the workstation, the member server, or the domain controller.
| Event ID | Meaning | Logged on | Why you care |
|---|---|---|---|
| 4624 | Successful logon | Target machine | Who got in, how (logon type), from where |
| 4625 | Failed logon | Target machine | Spraying, brute force, misconfigured services |
| 4648 | Logon with explicit credentials | Source machine | runas, lateral movement with typed creds |
| 4672 | Special privileges assigned | Target machine | Admin-equivalent logon; pair with 4624 |
| 4688 | Process created | That machine | Command lines (only if command-line auditing is on) |
| 4768 / 4769 | Kerberos TGT / service ticket requested | Domain controller | Kerberoasting, unusual service access |
| 4776 | NTLM credential validation | DC (domain) or local | NTLM use where Kerberos is expected |
| 4720 / 4728 / 4732 | User created / added to global / local group | DC | Persistence, privilege escalation |
| 4698 | Scheduled task created | That machine | Persistence |
| 7045 | Service installed (System log) | That machine | PsExec-style lateral movement, persistence |
| 1102 | Security log cleared | That machine | Almost never legitimate on a server |
