The evaluation speaks for itself. Forrester goes through great pains to assure a fair, detailed process that looks into the strengths and weaknesses customers care about most — and this Wave is no exception. But considering the amount of time and effort we spent putting this report together, I wanted to provide some additional thoughts on what I learned during the process:
I came across an interesting article discussing how the U.S. Department of State has recently shown interest in adopting network access control (NAC) tools that perform pre-admission access control. The intent is driving the development of standards that help organizations secure their network from malicious hacker attempts. There is a mounting concern that the nation's critical infrastructure — ranging from the electricity grid to banking systems to defense contractors — is far from being secure. To this end, the SANS (SysAdmin, Audit, Network, Security) Institute has worked with security professionals both inside and outside of government agencies to develop the Consensus Audit Guidelines. There are 20 controls in this program to tackle cybersecurity issues. NAC is identified to help with “Critical Control 12: Malware Defenses.”
Over the past 2 months, I've seen an increase in the number of end user inquiries regarding high availability and almost more importantly, how to measure high availability (HA). HA means something different depending on whom you're talking with so it's worth a quick definition. I define HA as:
Focused on the technology and processes to prevent application/service outages at the primary site or in a specific IT system domain.
This is in contrast to disaster recovery or IT service continuity (ITSC) which is about preventing or responding to outages of the entire site.
Why so many inquiries about HA recently? I believe that due to our increasing reliance on IT as well as the 24X7 operating environment that companies of all sizes and industries are becoming more and more sensitive to application and system downtime. The interest in measurement is driven by the need to continuously improve upon IT services and justify IT investments to senior management, especially now.
