Security best practices
By following these security best practices, you can significantly reduce the risks associated with PBXware and effectively protect your organization's communications.
Network, firewall and NAT
Check that only the ports required by PBXwareare open. Using dedicated VLANs for telephony is notably a good security practice.
Make sure that the web interfaces of phones connected to PBXware are not never accessible from the Internet, even on a port other than port 80 or 443. Many network scanners scan entire networks, can easily find open doors on your network and exploit them.
Password management
Use strong administrator and user passwords (8 to 12 characters, uppercase, lowercase, numbers & special characters) and encourage users to do the same.
Two-factor authentication
Enable two-factor authentication for sensitive access to PBXware. This strengthens security by requiring users to provide a second form of identification.
Access control
- PBXware allows tailored access control. Create site accounts with strict access control rules based on user roles and privileges.
- Immediately revoke access rights for users who are no longer authorized.
Log monitoring
- All PBXware events are logged in the section Action logs.
- Check these logs when suspicious activity occurs.
SSL certificate
- Use SSL certificates to secure HTTPS connections to PBXware.
- Monitor the validity of the certificates and renew them in a timely manner.
- See this link to learn how to install an SSL certificate in 2 minutes.
Install & use sipPROT
sipPROT is our defense tool against brute-force SIP intrusion attempts. This tool automatically blocks these failed attempts and modifies the access list to block IP addresses marked as potentially dangerous.
