Traveling auditors equipped with the proper tools can work in almost any setting, enabling them to maximize the time they spend on the road. The most basic of these tools is the portable computer. Other useful equipment are a modem and a facsimile machine that can be linked to a PC to serve the auditors' communication needs. Those who require large disk space may want to bring along disk doubler software packages such as Stacker 2.0. Programs such as Trusted Access, CRYPTOLock, Allsafe and Disklock can help auditors ensure the security of their data. In addition to these tools, it would be helpful if auditors had hard disk and floppy disk utility programs that can deal with various computer problems, including lost data and damaged disks.
