Mail server
Emails are considered sensitive data in any organisation. For security reasons, each organisation should have a dedicated email server . In this way, it protects itself from attacks and other malicious activities.
In addition to the content of email, the importance of data from everyday communication is the so-called metadata - information that is generated and exchanged by software and devices used for sending and receiving emails. For attackers, metadata is often more important than the content of the letter itself, because it carries accurate information about the digital context of communication. Metadata is stored on the mail server, so its protection is specific. The basic step in this direction is to block all protocols (for example, FTP or HTTP) that the server does not need to perform its primary function, i.e. receiving and sending emails. A dedicated server can be rented as part of a hosting package or other services, or an organisation can purchase a server with special software. An example of such software is iRedMail.
Alternatively, non-profit organisations can opt to use G Suite, i.e. Google’s productivity package which includes several popular tools and products (Gmail, Google Drive, Google Calendar, etc.). However, it should be noted that Google’s business model is based on user profiling and analysis of personal data collected from its users.
