Nu krijg ik een bericht dat mijn fritzbox niet veilig zou zijn - of alleszins dat hij open zou staan:
Dear Customer,
Zou dit te maken hebben met de mogelijkheid om sip-toestellen via het internet te registreren?Our preventive security scan service has picked up technical security issues with your voip-account.
It seems your phone system is not guarded against unauthorised access/use by your staff, or even external hacking.
Most commonly this is due to your system's non-compliance to our security requirements, which is also a breach of your contractual obligations.
We suggest you urgently check and secure your systems, or contact your IT service provider:
Your sip device is open on the public internet network.
We strongly suggest to review your firewall to isolate your voip equipment.
Your ip address : 81.XX.XX.XX
Your Customer ID : XXXX
Your VoIP device : AVM FRITZ!Box 7490 113.06.04 (Feb 11 2014)
| SIP Device | User Agent | Fingerprint |
-------------------------------------------------
| 81.XX.XX.XX:5060 | FRITZ!OS | disabled |
Hoe kunnen we dit veiliger maken?
