Is Your POS System Secure? PCI Compliance is Coming June 2018
SSL encryption is a standard encryption method used for decades. A vulnerability named POODLE has been detected within SSL and is no longer PCI compliant. POODLE (Padding Oracle On Downgraded Legacy Encryption) is a vulnerability in SSL that could allow a hacker to extract data from secure online connections.
Why should you care? Well, there could be a loss of confidential data that allows an attacker to decrypt sensitive information on your systems.
According to the PCI Standards Council Blog, the Payment Card Industry Standards Council (PCI SSC) is extending the migration completion date to June 30, 2018, for transitioning from SSL AND TLS 1.0 to a secure version of TLS (currently v1.1 or higher).
How Big is the POODLE SSL Vulnerability to POS Systems?
So How Do You Keep Your POS System Secure?
Once the deadline is up, the credit card processing functionality of any non-compliant equipment will cease. This is an industry-wide requirement. Most legacy POS systems are vulnerable and will need to be upgraded before the deadline.
To remain PCI compliant, merchants, in some cases, will need to update software, operating systems, and hardware. Merchants who refuse to upgrade their system will not be able to process credit cards once the deadline is met.
Harbortouch has gotten out ahead of the potential POODLE SSL vulnerability disruption and is entirely PCI compliant, but most POS companies are just starting to become aware of this issue, and it is likely that many of them will be severely impacted in the months to come.
First Data and other large processors were recently hit by a similar disruption over the holidays caused by the expiration of a security certificate called SHA-1. Harbortouch was unaffected since they were able to update all of the certificates to the new SHA-2 requirement through extensive conversion efforts. The POODLE SSL issue is going to be exponentially more severe than the SHA certificate since virtually all POS systems rely on SSL encryption.
