FEATURES, INSIGHTS // Email Security
Organizations may not be able to mitigate BEC scams entirely; however, tightening up processes will ensure data exposure is kept to a minimum.
By learning from the past there are many steps we can take to strength our approach to security as attackers continue to turn to email to help accomplish their mission.
“Evasive phishing" is not a term much heard, but we all will—and need to—start talking a lot more about it than we have in the past.
BEC is becoming increasingly profitable for threat actors as organizations are making it easy for adversaries to gain access to the valuable information that sits within these inboxes.
We should be thinking about how users work, what they do and how it affects the security posture of the business, but does security really start with them?
Ninety percent of breaches may begin with an email, but today most of the action happens well after an inbound email has been scanned and delivered.
Even organizations with the most robust defense solutions and advanced automated technologies cannot effectively combat threats such as BEC without the adequate support and nuanced expertise of humans.
To mitigate the risk of attacks, IT teams should disable unused tools and components, while deploying endpoint protection that doesn’t rely solely on file scanning or whitelisting.
DMARC is an email authentication standard designed to eliminate phishing and other types of attack that use spoofing to misrepresent an email sender identity.
Endpoint protection will never be able to catch up with “known wolves,” but machine learning and artificial perception can change the rules of engagement with models of “known good.”
