To protect corporate information, no resources can be overlooked.
In particular, it is important to always be alert for the protection of email servers. Email accounts are frequent targets of fraud campaigns for a reasonable reason: the attacker can take advantage of the corporate user’s carelessness or lack of knowledge to steal access privileges, leak information, or promote infection of devices or systems.
A basic need to protect corporate email accounts is to increase visibility into the environment. Therefore, Threat Intelligence must be associated with malicious message detection capabilities. And to be truly relevant, it is crucial that your email protection products be regularly updated. As the techniques and threats of cybercrime constantly evolve, intelligence information is also updated to more and more efficiently protect your environment.
Some features are crucial to assess the flow of messages that come in and out of your corporate mailboxes and to promote more security for your email accounts:
Control messages that can enter your environment: As with corporate networks, an e-mail firewall allows you to establish multi-conditional rules to determine whether or not a message should be received. In other words, rules aligned with you security and productivity policies, and threat intelligence allow you to assess which messages may be potentially inappropriate or malicious. This results in the ability to identify and block messages faster considering categories of content analysis, sender reputation, domain reputation, email authentication (D-MARC) etc.
Prevent confidential data from leaving your company: It is worth remembering that email is a frequent means of data leakage, so it is important to create a strategy that helps prevent sensitive data from leaving your organization through the mailboxes – whether due to negligence or premeditated action of a user. A DLP – Data Loss Prevention feature should be able to help you set up rules to identify sensitive information within any message sent by your collaborators and quickly act on it – be it blocking, notification, redirection, or even authentication by captcha.
Store information securely: Mailboxes are commonly used as file and communications history. Message archiving can even serve the purpose of maintaining records to create compliance with standards and regulations. But to keep sensitive information in users’ boxes, it is crucial that your security product be able to apply encryption to all available content. End-to-end encryption ensures that all messages stored on the server are secure.
Protecting your users’ mailboxes should be one of your company’s security priorities, so when it comes the time to choose an e-mail protection, consider those three factors.
