Questions:
Question 1. For this thread consider your work environment (or a prior work site if you're uncomfortable discussing your current work site). How secure is it? Are there alarms? Cameras? Fencing? Lighting? Guards? Locks? Keypad access? If you don't think adequate physical security measures are present, why do you think that is and what would you recommend?
Question 2. Assess your organization (or a prior place of employment) but this time from a personnel security aspect. Does your organization conduct background checks - and to what levels - and why do they do that? If they don't, should they, and how extensive should they be? What should be included?
