Cybercrime Prevention for Your Networks and POS Stations
While there is no “perfect solution” to your POS security, there are plenty of best practices that can be used to increase the security of your networks and the data that flows through them. These best practices include:
Maintaining the Most Up-to-date POS Software
POS software updates ofteninclude important security patches that, if not installed, can leave your POS system vulnerable to malware and other attacks that could put your data at risk. Downloading and installing updates in a timely manner will keep POS networks and hardware far more protected than choosing to do updates quarterly or on some other schedule.
Installing a Firewalls and Anti-virus Software to Protect POS Networks
POS systems are at constant risk of compromise at the hands of hackers, viruses, spyware and other malware that’s been designed to infiltrate and compromise POS systems. Using a firewall and anti-virus software does not guarantee complete protection, but should nonetheless be used as part of an overall protection system that keeps your POS hardware and network secure.
Creating strong passwords and changing them often
Unfortunately, POS system installers are prone to using default passwords upon initial setup of online payment processing systems for merchants and not changing the passwords to something more secure. Using the default password makes life easy for the installers, but these passwords are fairly easy for criminals to obtain. Using complex, computer-generated passwords and unique account names are highly recommended. It’s also advisable to change passwords on a regular basis.
Denying Internet Access from POS Stations and Terminals
When you restrict POS computers and terminals from accessing the Internet, you protect them from exposure and potential security threats such as viruses and other malware. POS systems should be connected only for necessary POS activities and should not be used for any general Internet usage. One click on a malware- infected site by an employee on a POS device could be disastrous for a business.
