What are the data loss prevention (DLP) capabilities within Exchange Online, and how does it prevent sensitive email content from being shared with unauthorised recipients?

• Content Detection: DLP uses predefined or custom policies to scan email content for sensitive information such as credit card numbers, Social Security numbers, confidential documents, or specific keywords. It employs advanced pattern matching, regular expressions, and machine learning to identify sensitive data accurately.
• Policy Creation: Administrators can create and customise DLP policies to meet their organisation's needs and compliance requirements. These policies define actions to be taken when sensitive data is detected, such as blocking the email, encrypting it, or notifying the sender and recipient.
• Policy Enforcement: DLP monitors outgoing emails once policies are configured. If it detects sensitive content, it triggers the defined action. For example, it can prevent the email from being sent or notify the sender, educating them on the policy violation.
• User Education: DLP also plays a role in user education. When a policy violation occurs, users are informed of the issue and guided on how to rectify it. This helps raise awareness and encourages responsible data handling.
• Incident Tracking: DLP maintains detailed logs and incident reports, allowing administrators to track policy violations, investigate incidents, and take corrective actions.
• Policy Templates: Exchange Online offers a range of built-in policy templates designed to address standard compliance requirements like GDPR, HIPAA, or industry-specific regulations. These templates simplify the policy creation process.

Overall, Exchange Online's DLP capabilities provide a proactive and granular approach to data protection by identifying and preventing the unauthorised sharing of sensitive email content, reducing the risk of data leaks and ensuring compliance with data protection regulations.

Can Exchange Online's backup and recovery features protect against accidental email deletion or data loss, ensuring business continuity?

• Email Retention: Exchange Online has built-in retention policies that can be configured to retain deleted emails for a specific duration. Even if a user accidentally deletes an email, it can often be recovered within the retention period.
• Deleted Item Recovery: Users can recover deleted items from their Deleted Items folder or the "Recoverable Items" folder within a specific timeframe, usually 30 days by default.
