Using Office 365 for your business productivity tools certainly has many advantages; easy, user-friendly accessibility from anywhere and at anytime, simplified email access, and reduced costs of business operations and management.
However, the migration and use of Office 365 isn’t without security risks. In this article we look at 5 of those risks, and how your organisation can get best in class protection from ourselves and Barracuda solutions.
1) Defend your Office 365 environment against email-borne threats
Barracuda Essentials for Office 365 stops spam, viruses, and known malware using signature-matching that leverages Barracuda’s vast global threat intelligence system, which gathers real-time threat data from millions of collection points around the world. It also includes a subscription to Barracuda Advanced Threat Protection—a cloud-based service that uses a multilayered architecture with a CPU-emulation sandbox to detect and block new (zero-day) and advanced, evasive threats before they touch your deployment.
2) Prevent data loss and theft
Outbound email filtering protects sensitive data against accidental or deliberate leaking. You can define keywords to look for, along with specific types of data (social-security and credit-card numbers, for example). And if your users have inadvertently allowed their systems to be used for botnet spam, Essentials ensures that outgoing spam and viruses are blocked.
Sensitive emails can be manually marked for encryption, or you can set up rules to automatically encrypt emails based on the sender, content, and other criteria. Your Office 365 emails are sent to the Barracuda Message Center for 256-bit encryption in the cloud. They remain encrypted via Transport Layer Security (TLS) until they reach the intended recipients.
3) Discover latent threats in your mailboxes
The email files stored in your Office 365 environment almost certainly include latent threats—malicious URLs and attachments that are just waiting for a single distracted click to launch an attack on your network. Given the volume and variety of threat-bearing emails, it’s not realistic to consider a manual approach to finding and deleting them all.
The Barracuda Email Threat Scanner is a cloud-based service available to anyone, at no charge. It scans your Office 365 email folders using advanced analytic techniques. It then delivers a report that details all the latent threats, including risk levels, affected users, and more. The information not only lets you clear out the latent threats in your environment; it also gives you the insights you need to adjust or improve your email security policies and strategies to reduce the chance of more malicious email getting into your system.
4) Don’t fall victim to phishing, brand hijacking, and domain fraud
The most sophisticated email-based attacks are the ones that personal. Attackers convincingly impersonate legitimate businesses, colleagues and even customers to obtain sensitive data and money. Barracuda Sentinel uses artificial intelligence engine to add real-time defense from email-based fraud.
Barracuda Sentinel automatically learns the unique communication patterns of each individual organisation. It uses this knowledge to find anomalous signals in the attributes of the incoming message’s metadata and content. It also adds DMARC (Domain-Based Message Authentication Reporting & Conformance) to track potentially sensitive emails being sent from your organisation.
5) Turn employees into a line of defence against phishing attacks
Phishing attacks are more convincing than ever, and they can be difficult to spot. To complicate matters, the attackers are targeting unsecured personal mail accounts more than ever. As a last line of defence, employees need to get better at spotting socially engineered spear phishing attacks.
Barracuda PhishLine provides leading-edge user awareness training to counter sophisticated phishing and socially engineered spear phishing attacks. PhishLine helps your users sharpen their anti-phishing skills with advanced phishing simulations along with end-user testing, reporting, and comprehensive metrics that let you take prompt and meaningful action against threats.
