In Exchange Server, Microsoft has enabled multiple security features and they are effective enough to be prepared against several external threats. Some are enabled by default, and some are available for you after you enable them manually. Here are some security settings, filters, and protection features present in Exchange.
- Ant-spam and antimalware protection
- Content Filtering
- Sender Filtering
- Attachment Filtering
Ant spam and antimalware protection is present in the Exchange Server 2016 and 2019. Anti-spam protection is provided by the in-built transport agents and is enabled by default on Edge Transport servers.
Antimalware was introduced in the Exchange Server 2013 and is present to protect all the mailboxes of the Exchange Server.
Content filtering checks all the incoming messages for their legitimacy. The filter checks whether the email is genuine or spam. It matches the message from the existing samples of genuine and spam emails and then decides whether to allow the message or not.
Sender Filtering keeps a list of blocked senders and evaluates the value of the MAIL FROM of the SMTP connections from the blocked sender’s list. This feature is present in Exchange since Exchange Server 2010.
Attachment filtering works on the Edge Transport servers and handles the incoming email message that has the attachments. It is done by the Attachment Filtering Agent and there are several actions to perform like Filtering based on a file name or file name extension, Filtering based on file MIME content type, Reject (block) the message, Strip the attachment but allow the message through, silently delete the message, etc.
In Exchange, Microsoft has included many data protection features which empower administrators to meet compliance requirements and face data disasters. A combination of these native data retention methods helps them meet all their data retention requirements easily.
Generally, the following are the scenarios which Exchange administrators have to be prepared for.
- Disaster Recovery
- Recover accidentally deleted items
- Backup storage for long term
- Point-in-time Database Snapshot
Database Availability Groups (DAG) keep multiple copies of the databases to ensure availability of data always. In the case of failure of software or hardware, users can easily get data from any member of the database availability group. You can extend these database availability groups to a variety of sites and save yourself from any storage, server, data center, or network related failures.
Generally, the recovery process of deleted items includes finding the backup file where the data was saved earlier, then accessing the data from it and restoring to the database back. But the latest version of Exchange Server 2019 and 2016 provides Recoverable Items Folder. You can apply a Hold Policy on the Recoverable Items Folder too, and it will hold the deleted and modified data for a given period. It makes it easy for administrators and users to access the data from the folder, and there is no need to run any recovery procedure.
Backups are the most common form of storing the Exchange data at a safe location and later retrieve it in case of any database failure. Backups are archives which are encrypted and protects the data for the long term. The latest Exchange backup archiving, multiple mailbox search and message retention features have increased the safety of data, and now the user can save the data for a longer period.
Point-in-time snapshot is a unique feature which creates a lagged copy of the database at the database availability group. It is useful in a scenario when a logical corruption has hit the Exchange, and you need to go to a previous state of the Exchange. It is also helpful in restoring the accidentally deleted items. The advantages of using the point-in-time snapshot are that it takes quite less time than a backup for restoring the data. It does not require the copy process from the backup server to the Exchange server.
With the help of native Exchange data protection features, you can strengthen your data retention capabilities. But there are multiple threats like malware, spyware intrusion, hardware failure, software failure, user errors which cause the Exchange database to become corrupt. In such a case, you need expert assistance, which helps you to fix the error and recover all the data. Also, you can fix the issues with the help of a good Exchange recovery tool like Recoveryfix for Exchange Server Recovery.
