Staffing and Training
Hiring staff: Expertise
Training is necessary because few people on the market are security experts
Certifications are good but vary in what they require and do not make up for lack of experience
Background checks should be done on the security staff

Figure 11-1: Organizational Issues
Staffing and Training
All workers involved in IT should have background checks, including the maintenance staff, consultants, and contractors
Should you hire a hacker?
They are likely to have the knowledge you need
But would you be afraid to fire or lay off one?
