@Risk: Security Alert
OUCH! Security Awareness
Case Leads DFIR Digest
Industrial Control Systems
Industrials & Infrastructure


@RISK provides a reliable weekly summary of (1) newly discovered attack vectors, (2) vulnerabilities with active new exploits, (3) insightful explanations of how recent attacks worked, and other valuable data

A key purpose of the @RISK is to provide the data that will ensure that the 20 Critical Controls (the US and UK benchmark for effective protection of networked systems) continue to be the most effective defenses for all known attack vectors. But since it is also valuable for security practitioners, SANS is making it available to the 145,000 security practitioners who have completed SANS security training and others at their organizations who hope to stay current with the offensive methods in use.

TOP VULNERABILITY THIS WEEK: Adobe patches dozens of vulnerabilities in Acrobat, Reader


******************** Sponsored By ExtraHop ****************


"Investigate East-West Attack Activities to Defend Critical Assets: A SANS Review of ExtraHop Reveal(x)"  Dave Shackleford puts ExtraHop Reveal(x) through its paces using a use case of an outside attacker who has compromised an internal system. The attacker is scanning the network, trying to gain access to a file share through brute force, pulling down data and exfiltrating that data. Attendees will learn about the role of machine learning in detecting and responding to threats.  Register: http://www.sans.org/info/207120
