Message Content Examination
Once a message is identified, its content is examined to determine its legitimacy and potential risk. This involves reviewing the sender’s address, subject line, message body, and any attachments. Administrators may need to utilize tools to scan attachments for malware or examine URLs for phishing indicators. For instance, a message claiming to be from a financial institution might require verifying the sender’s domain and inspecting links for redirects to fraudulent websites. Failure to thoroughly examine content can result in the release of malicious emails into the network.
-
Sender Authentication and Reputation Assessment
A key aspect of the review process is authenticating the sender and assessing their reputation. This involves verifying the sender’s domain using SPF, DKIM, and DMARC records, as well as checking against known blocklists and threat intelligence feeds. For example, a message appearing to originate from a legitimate vendor might be quarantined if the sending domain fails authentication checks or has a poor reputation score. Inadequate sender authentication can result in spoofed emails circumventing security measures.
-
Policy Compliance Verification
The review process also includes verifying whether the message violates any organizational policies regarding content, data leakage prevention (DLP), or acceptable use. For instance, a message containing sensitive financial data might be quarantined if it violates DLP rules. Administrators must understand and apply these policies consistently during the review process. Non-compliance with established policies can lead to data breaches and regulatory violations.
These facets highlight the complexity and importance of the quarantine review process. A well-defined and consistently applied process is essential for ensuring that the decision to release or keep quarantined messages is both secure and aligned with organizational needs. Without a robust review process, the act of releasing a quarantined message becomes a significant security risk, underscoring the vital link between careful evaluation and secure email management within Office 365.
3. Message legitimacy assessment
The evaluation of a message’s legitimacy is inextricably linked to the secure and effective process of releasing quarantined email within the Office 365 environment.
