5. Beware PC Anywhere.
Tools that provide remote access to employee systems such as PC Anywhere are commonly used by hackers as an unlocked backdoor into corporate systems. Network managers can use IP blacklisting to block which systems have access to these tools as well as egress filtering to prevent sensitive information from flowing out of a corporate network. Data loss prevention and intrusion detection systems can help, too.
6. Warn your security guards.
Enterprises are seeing more hacking attacks that result from physical tampering with network devices in the data center. Corporate security guards should be on the watch for unscheduled servicing of network devices as well as the presence of scratches or holes on the outside of equipment or broken tamper-proof seals on hardware. Automated teller machines and point of sale systems are frequent targets of physical attacks.
7. Train your employees.
Hackers often trick employees into divulging information, such as user name and password, or performing an action, such as downloading an executable file or visiting a phony Web site that contains malware. Companies need to engage in ongoing training for employees that keeps them constantly aware of the threat of these social engineering attacks.
