Private security is about more than just patrolling the outside of buildings, it also involves protecting important computer information, preventing identity theft and making sure all forms of transportation are safe and secure for everyone. Since the onset of the war on terror, the face of security has changed -- now more than ever, security depends on computers and up-to-the-minute technology to ensure the safety of everyone. Transportation and computer technology have been the most exposed to the numerous hazards and changes associated with this.
The transportation and cargo industries are under extra scrutiny because of their accessibility to terrorists, who may use these industries to transport weapons of mass destruction or to endanger the lives of innocent civilians.
In addition, private citizens and the government rely on computer systems that invite a plethora of problems including identity theft and terrorist hackers. Retailers must especially be on guard for identity theft which is commonly achieved through stolen credit cards and personal checks -- costing consumers and businesses hundreds of millions of dollars every year. Important personal information can also be intercepted by the wrong people and used in terrorist threats against the U.S.
