Open Security Advisor and run a scan:
1. If it’s the first time, choose Home or Work and click Start.
2. In Security Advisor > Overview, click Scan.
3. Review the result:
- Warning: low/moderate risks
- At Risk: high risks
- Danger: malware found
- Out-of-date: DSM is outdated
To reduce risk, the knowledge base recommends:
- Deactivate the default admin account.
- Configure user permissions and password strength rules.
- Enable the firewall: Control Panel > Security > Firewall > Enable firewall.
- In Security Advisor > Advanced, enable regular scan schedule.
- If DSM is Out-of-date, update DSM.
For checking and patching DSM:
- Check available updates: sudo synoupgrade --check
- Download latest upgrade: sudo synoupgrade --download
- Start upgrade: sudo synoupgrade --start
- Or upgrade automatically: sudo synoupgrade --auto
If you want only package updates, use:
- synopkg checkupdate {{package}}
- sudo synopkg upgradeall
