Credit card information encryption is one of the fundamentals of PCI DSS compliance. Recently more and more attention was directed at the need for enhanced data protection. The overall gist of the PCI DSS appears to indicate that retailers should just keep the bare minimum of information in their system In other words, only the information specifically required for legal, business, or other similar needs should be held within an internal system. And all that information must be encrypted.
And studies have shown that many companies are failing to execute appropriate credit card data encryption steps. Why is this? It could be due to the confusion and costs associated with credit card data encryption. Appropriate encryption may require greater resources than normal, such as bandwidth, processing, and staff resources. When companies begin calculating the costs associated with these new security measures, many seem to think it is worth a little risk so as to save the cash and resources.
After all, they might say, sure some companies have been targeted and breached. But really, do that lots of businesses have a problem. Certainly, out of all of the businesses in the world, a hacker would not target me.
The unfortunate fact, however, is that hackers will, in fact, targeting anyone. And while many companies have trouble spending funds to fend off a potential problem that is just what the PCI DSS requires you to perform. Requirement three of the PCI DSS requires you to Protect stored cardholder data. Credit card information encryption is crucial to this requirement. The notion here is that anybody who happens to skip any or all your other safety measures will find just a string of illegible gibberish. The only way a criminal can use these amounts is if they get a hold of their encryption keys also.
This brings us to a different part of appropriate credit card information encryption: proper storage and care of encryption keys. Lots of the prtship forum requirements here reflect those of routine data security. By way of instance, a merchant must restrict access to the keys into the fewest number of people possible, and they need to be saved in as few locations as possible. Additionally, there are requirements to be certain a merchant uses the keys they could. A merchant must create strong keys, securely store and transmit them, and also occasionally change their encryption keys and properly dispose of old ones.
Many companies these days are choosing to outsource their information security needs. Businesses that specialize in credit card data encryption may implement all of the appropriate security measures around sensitive information and encryptions keys. By outsourcing these processes your business can continue to operate as normal with minimal interruptions. Credit card data encryption, then, is required at both endpoints and in transmission. Anything less makes you a target for Individuals with questionable motives.
