How can you secure OpenERP email communications?

1 Configure SSL/TLS encryption

The first step to secure OpenERP email communications is to configure SSL/TLS encryption for your email server and your OpenERP instance. SSL/TLS encryption ensures that the data exchanged between your email server and OpenERP is encrypted and authenticated, preventing anyone from reading or modifying it in transit. To configure SSL/TLS encryption for your email server, you need to obtain a valid SSL certificate from a trusted authority and install it on your server. To configure SSL/TLS encryption for your OpenERP instance, you need to enable the SMTP SSL option in the Settings > Technical > Email > Outgoing Mail Servers menu and enter the correct port number for your email server.

2 Use strong passwords and authentication methods

The second step to secure OpenERP email communications is to use strong passwords and authentication methods for your email accounts and your OpenERP users. Strong passwords are passwords that are long, complex, and unique, and that are not easily guessed or cracked by attackers. Authentication methods are ways to verify the identity of the email sender or receiver, such as username and password, two-factor authentication, or digital signatures. To use strong passwords and authentication methods for your email accounts, you need to follow the best practices and policies of your email provider or server. To use strong passwords and authentication methods for your OpenERP users, you need to enable the Password Policy and the Auth Crypto modules in the Settings > Apps menu and configure the password rules and the encryption algorithm in the Settings > General Settings menu.

3 Restrict access and permissions

The third step to secure OpenERP email communications is to restrict access and permissions for your email accounts and your OpenERP users. Restricting access and permissions means limiting who can access, send, receive, or modify your emails and your OpenERP data, and what they can do with them. To restrict access and permissions for your email accounts, you need to use firewall rules, IP whitelists, or VPN connections to block or allow access to your email server from certain locations or devices. To restrict access and permissions for your OpenERP users, you need to use the Groups and Access Rights features in the Settings > Users & Companies menu to assign roles and privileges to your users based on their functions and responsibilities.

4 Monitor and audit email activity

The fourth step to secure OpenERP email communications is to monitor and audit email activity for your email accounts and your OpenERP users. Monitoring and auditing email activity means tracking, logging, and reviewing the email messages sent and received by your email accounts and your OpenERP users, and detecting and reporting any suspicious or abnormal behavior. To monitor and audit email activity for your email accounts, you need to use tools such as log files, reports, or alerts provided by your email provider or server. To monitor and audit email activity for your OpenERP users, you need to use the Mail Tracking and the Audit Log modules in the Settings > Apps menu and configure the tracking and logging options in the Settings > Technical > Email menu.

5 Update and backup regularly

The fifth step to secure OpenERP email communications is to update and backup regularly your email server and your OpenERP instance. Updating and backing up regularly means applying the latest security patches and fixes for your email server and your OpenERP instance, and creating copies of your email data and your OpenERP data in case of loss or damage. To update and backup regularly your email server, you need to follow the instructions and recommendations of your email provider or server. To update and backup regularly your OpenERP instance, you need to use the Update Modules List and the Database Backup features in the Settings > General Settings menu and schedule the update and backup frequency and location.
