What are malicious email attachments? How to stay protected
Not every email attachment is as benign as it seems. Malware has many forms, and just as many ways (vectors) it could arrive from. Of these, malicious documents attached to emails might be the most common method. It’s simple: You receive an email from a sender (known or unknown) suggesting you open the attached document in it—to check the results of a tax audit, for example. What happens next depends on what sort of file the document is: Is it a PDF? A docx with macros e

Future-ready: How to secure enterprise data pipelines

What is a Security Operations Center (SOC)?
SOCs provide continuous monitoring, threat detection, and incident response. If you’ve heard of a Security Operations Center (SOC), but never seen one, one might picture a huge, bustling control room with enough large screens to run a mission to Mars.
