by Lalita Negi on September 21st 2018

Earlier, we discussed top reasons to choose office 365 mainly due to its security features and compliance. Today, we are going to discuss what those features are and explore them in depth.

Office 365 Enterprise edition that comes with utmost features and is most suitable for all businesses and professionals alike, contains protection against all kind of threat such as malware, spam, phishing attempts, ransomware, spoofing, unauthorized access and more.

We will be talking about each of them separately and how office 365 provides complete protection against them.

●      Anti-Spoofing

●      Anti-Spam & Anti-Malware

●      Advanced Threat Protection

●      Data Encryption

●      Threat Intelligence

Anti-Spoofing

Email Spoofing is very common in today’s date. Cloaking someone’s information to wear a false identity is a deceiving technique used to fool others. Office 365 has inbuilt advanced anti-spoofing capabilities that help prevent protecting against such potential fraud emails from outside domains.

Usually, office 365 verifies external emails which are having proper SPF, DMARC, and DKIM authentication. At times, some legitimate external domains to don’t have these settings properly configured leaving the recipient in further ado. New enhanced features help detect such cases and further scrutinizes them for potential threats.

When one such case is detected, the filter deeply checks for historical email patterns of that domain and associated relations. If any suspicious activity is found, it proceeds to junk the email while maintaining a note of that sender’s identity. This enhanced ATP filter constantly evolves and enhances itself learning from the observed mail flow pattern.

Anti-Spam & Anti-Malware

An everyday user typically encounters daily spam and occasional malware on a general basis. Spams are those emails which you haven’t requested and/or are not interested in receiving. These are mostly promotional kind of mail which are bombarded to all the recipients of a particular target group mailing list. Malware, on the other hand, is comprised of viruses, trojans etc to steal your information and cause damage.

Office 365 comes with inbuilt anti-spam as well as anti-malware capabilities, both of which we will discuss further in detail within this article. Users need not worry about setting up filters or manage them, they are enabled by default. However, if you wish you can make some specific customization changes via Exchange Admin Center(EAC).

There are three basic inbuilt sets of rules in the Office 365 that are used for protection against spam and malware :

●      Connection Filtering

●      Spam Filtering

●      Outbound Filtering

Moreover, if you are not content with the above-inbuilt default features of Office 365, you can do so much more. There are other email authentication and verification settings such as Sender Policy Framework(SPF), DomainKeys Identified Mail(DKIM), Domain Message Authentication, Reporting, and Conformance(DMARC). We will be covering and each of them in complete detail in our upcoming blog posts.

Also, you can enable mailbox auditing and submit a potential threat file to Microsoft for further analysis.

There are couple other relatively more advanced features such as Advanced Threat Protection, Encryption, Threat Intelligence which we will be covering in our next part of this post. So, stay tuned and subscribe to our facebook page to receive the latest updates.
