I am looking for resources and details on establishing a security operation center (SoC) or network operation center (NoC) based on ITIL or any other applicable regulations. Where can I find good details or experiences of others except for hiring consultants.
Here is some experience about establishing projects, especially security projects, that applies to consulting and outsourcing that I wrote up on a security stackexchange answer about incident compromises.
As for resources, well it is highly dependent on your environment as to what you would need to build and how many people to hire (and at what levels of qualifications). In many ways, a good strategy consultant or two could push you into making better decisions, but if you want the real story -- let me give you some additional advice.
Security events and incidents are best tracked by personnel that are already familiar with SIEM and incident detection & response (IDR) panels -- so look for candidate with past hands-on and strategic long-term experience with SIEM/log-management/IDR. For staffing, Lance Hayden analyzes the current security event/incident stream using Poisson distribution in Minitab, as explained in his book, "IT Security Metrics". He also goes into business workflow and other concepts that are highly important to building a quality SOC.
SIEM costs money, but there are books and resources to get a SOC started. Most security incidents in 2011 are SQL injection (or other web app layer attacks) and client-side browser/document attacks (e.g. Adobe Reader/Flash, Microsoft IE/Office/ActiveX, Oracle Java applets, etc). It is highly suggested that your SOC team be familiar with the techniques and tools outlined in this blog post entitled Closing The Loop. While not to tone down the other, more important information in that blog post -- there is something of specific interest to you, [PDF] [the CSIRT Handbook]6 [download]. That paper is old, but still very relevant.

These books will also be helpful, in order of necessity:
