What Is Microsoft Defender for Office 365?
One of the benefits of using Microsoft 365 is that it offers a lot of different security protections, which are vital in today’s online threat environment.
The disruption caused due to the global pandemic led to a significant rise in online threats and cybercrime around the world as well as in Australia. There was a 51% increase in spyware globally in 2020 as well as a 20% increase in global ransomware, and a 10% increase in Australia.
While your standard Microsoft 365 business accounts include several security features, Microsoft offers extended protection from phishing attacks, malware, and other malicious threats through Microsoft Defender for Office 365. This is available in Microsoft 365 Business Premium as well as Enterprise accounts.
We’ll go through the features of the tool below and how it can help keep your Sydney area business more secure.
Features of Microsoft Defender for Office 365
Microsoft Defender for Office 365 offers more security capabilities and features to protect your business against a variety of online threats.
Some of the tools include:
- Real-time reporting on threats and response performance
- Ability to define threat-protection policies at the levels needed for your company
- Ability to investigate, understand, simulate, and prevent threats
- Time-saving automated investigation and response
Here are some of the features you’ll find in this security application.
Safe links is specifically designed to combat today’s phishing attacks. While some phishing does still use file attachments, a majority of it now uses links instead to try to get past anti-malware programs.
51% of phishing attacks contain malicious links rather than file attachments.
What Safe Links does is scan messages for hyperlinks and matches those against a database of malicious sites. If it identifies anything malicious it can rewrite the message to strip the link, protecting the user from a potential cybersecurity issue.
Safe Links can be activated through policies to protect:
- Email messages
- Messages shared in Microsoft Teams
- Messages shared in other Microsoft 365 apps
Safe Attachments is a feature that gives additional protection over a standard anti-malware scanning. Online threats have become increasingly sophisticated, meaning that some dangerous file attachments might make it past a first line of security.
This feature uses a virtual environment to check attachments in email messages for anything malicious before the message is delivered to the user.
Advanced Threat Protection (ATP) for SharePoint, OneDrive, and Teams
What happens if a malicious file makes it into your system in another way, not through email or a new message? ATP is designed to protect against these and keep any areas where you store cloud files secure.
ATP for SharePoint, OneDrive, and Teams will look at files that already exist in your account. If it detects anything malicious, it can block access to the file to prevent device infection.
When a dangerous file is blocked, it can be deleted by users, but cannot be opened, copied, moved, or shared.
Phishing is the #1 delivery method for ransomware, viruses, and other types of malware. Microsoft Defender for Office 365 gives you additional strong policy protections against phishing to keep your team secure.
One of these is a protection against spoofed emails. This is where the attacker uses your own domain or that of a company you may recognise in the “From” line of the email to trick the user into trusting it.
The anti-phishing policies in the application prevent this type of email impersonation by allowing you to block designated internal and external addresses from being spoofed as message senders.
You can also set specific advanced phishing thresholds for protecting your organisation from phishing attacks. These include:
- More aggressive
- Most aggressive
Explorer & Real-Time Detections
You gain advanced visibility into what’s happening with your account through use of Explorer and Real-time detections in Microsoft Defender for Office 365.
