True or False? POS systems are secure upon set-up. FALSE: weak passwords, improper system set-up, insecure remote access, unpatched software, untrained employees, missing remediation plans, and malware infection are all potential ways in which a POS system can become vulnerable over time. Consider each of these elements when auditing the POS system. Improve passwords, patch software, secure remote access, train employees, develop policies and remediation plans, and install up-to-date antivirus software to combat these dangerous attacks.
