I am examining our organizational lay out and each teams roles and responsibilities. Briefly, these are some of the roles that I am looking at
Administration (servers, desktops, routers, switches)
Administration of security focused system (Network IPS, anti virus)
Patch management (security vulnerabilities)
I am leaning toward 3 teams.
Info Sec - policy and compliance
Operations - administration
Security Operations - log analysis, security architecture, patch management and assessments
