Cybersecurity Blog: The Cyber Scene is evolving, are you?

Please see links below to Case Studies in Financial Services Cybersecurity:

Overview

Critical infrastructure is not limited to just the energy and utilities sectors. The Financial Services sector is just as critical to a country's security as any nuclear power plant or energy delivery system. It is a hard to imagine our lives with an impaired or disrupted financial commerce system. To address this threat the Financial Services Information Sharing and Analysis Center (FS-ISAC) was launched in 1999. It is the global financial industry's go to resource for cyber and physical threat intelligence analysis and sharing. FS-ISAC is unique in that it was created by and for members and operates as a member-owned non-profit entity. Leidos Cyber, Inc. is proud to be an “Affiliate Member” of FS-ISAC.

The remark “never a dull moment” is rarely an expression used to indicate joy.  Instead, it’s a semi-sarcastic way of lamenting unwelcome excitement.  While no one wants to have a boring job, spending one’s time fighting ransomware outbreaks that disrupt business operations and put one’s job at risk are not the kinds of exhilarating challenges that most Chief Information Security Officers (CISO) pine for.  The recent WannaCry outbreak has all the hallmarks of this unwelcome excitement.  The ransomware infects computers by exploiting a vulnerability that Microsoft patched two months ago.  It propagates through a network port that every enterprise should be locking down.  It exhibits malicious behavior that should be relatively easy to detect and mitigate.  By some accounts, it was arguably a poorly executed attack that did a mediocre job of accomplishing what appears to be its most important objective - extracting money from its victims.

Technological advances notwithstanding, program security still comes down to one basic element: well written code.
