DoD 8140 Cyberspace Workforce Management Policy will replace 8570.  8140 will be based on the National Cybersecurity Workforce Initiate.
National Initiative for Cybersecurity Education (NICE) has developed a National Cybersecurity Workforce Framework which breaks down the most common cybersecurity jobs into tasks and skill sets.  This framework will explain requirements in cybersecurity roles just like other professions do.  For example, in order for lawyers to practice law they must pass the Bar.  They are trying to do something similar to this with system security analysis for the federal government in that you will have to have X certification and/or X degree.
There is an interactive website that promotes this: http://niccs.us-cert.gov/training/tc/framework
Among working IT professionals in the field there is a little controversy about how 8570 would focus too much on certifications and not at all on experience or even taking into account a degree. Â This is a problem since you end up getting a lot of unqualified people
working in sensitive jobs that they have no experience or mentor ship in just because they have passed a test. Â I hope DoDD 8140 will remedy this.
More on DoD 8140
8140 was expected to be published in January 2014.  Similar to 8570, DoD 8140 will provide a comprehensive view of the cybersecurity workforce but with changes to levels I,
II, and III to apprentice, journeyman, and master.  It will be integrated into the job skills and functions you see in the National Initiative for Cybersecurity Education (NICE) framework, and mission area requirements from the U.S. Cyber Command (USCYBERCOM) workforce.
