What are the typical duties of an it security guard

ecure premises and personnel by patrolling property; monitoring surveillance equipment; inspecting buildings, equipment and access points; permitting entry. Obtain help by sounding alarms. Prevent losses and damage by reporting irregularities, informing violators of policy and procedures; restraining trespassers.

i think it can have both positive and negative effects on businesses.

for example:

lets say you own a small business and taxes go up 4% that means it is going to cost your business more money to buy product to sell. but at the same time you make more money from the tax rise.

that is my theory.
