But mobile workers also can pose potential security threats, such as those stealthy employees intent on unauthorized intrusion. Security threats to companies and individuals posed by mobile workers exist on several levels. The IT department must consider the potential impact on users and ad-ministrators, as well as systems. Workers can gain unauthorized access to trade secrets, classified information, or company data on local machines. They can also damage stored information and destroy hard-disk contents.
Unauthorized access can lead to loss of productivity.
Missing, damaged, or altered data can result in substantial productivity loss and affect the IT resources required to recover those resources. Not only is the mobile worker out of action, but additional IS staff is required to resurrect the damaged systems. Application intrusion and proxy execution pose another sort of security threat. Let there be no doubt that online security is becoming fundamental for a company's survival in the frenetic world of E-business. Businesses, government agencies, and nonprofit organizations are IT-intensive and totally dependent on their information systems to operate on operational, tactical, and even strategic levels.
