Tech News Summary:

  • Microsoft proposes a new Exchange Online security feature that will automatically block all emails received from “Consistently insecure Exchange Servers” 90 days after administrators are notified to protect them.
  • The feature aims to assist Exchange administrators in finding outdated or unsupported Exchange servers so they can update or fix them before they become a security issue. The ability to restrict or block emails from unsafe servers in the environment will also be available.
  • The enforcement system uses a gradual strategy to escalate the severity of the situation until the vulnerable Exchange servers are fixed or removed from operation. This news follows a call to action from Microsoft in January urging users to deploy the latest supported cumulative update on their on-premises Exchange servers.

In a move to increase the security of its email service, Exchange Online has announced that it will now filter incoming emails from unsecured local servers. This means that any emails received from servers that do not meet the security criteria set by Microsoft will be automatically blocked, preventing potential threats from reaching the recipient’s inbox.

According to Microsoft, unsecured local servers are a major cause of email security breaches, with many cybercriminals using them as a way to send phishing emails or distribute malware. By adding this filtering feature to Exchange Online, the company hopes to reduce the number of security incidents caused by these servers.

The filtering process will be done using the latest threat intelligence and machine learning algorithms, which will be continually updated to stay ahead of new threats. Emails that are flagged as potential security risks will either be blocked or quarantined, depending on the severity of the threat.

Customers who use Exchange Online do not need to take any action to benefit from this new feature as it will be enabled by default. However, customers who require emails from unsecured servers to be passed through can create custom rules to ensure that these emails are not blocked.

Exchange Online’s new filtering feature is part of Microsoft’s ongoing effort to make its services more secure and protect its customers from cyber threats. With the increasing sophistication of cyber attacks, it is crucial for companies to stay vigilant and take proactive measures to safeguard their digital assets.
