Use and Maintain Firewalls A firewall protects private data from access by any foreign or unknown entities. These are the main defence system against unknown entities and hackers. A firewall is effective for preventing unauthorized access to user data.
Proper Password Protections The generic password of the modem, point of sale (POS), Routers are all password protected. People usually access these applications, so security is essential. Compliance measures are undertaken by ensuring passwords for all devices including software.
Protect Cardholder Data Twofold protection of cardholder data is the third PCI DSS compliance requirements. Encrypted algorithms protect cardholder data. Encryptions are protected and secured by encryption keys. Encryption keys are further encrypted for compliance. Scanning and maintenance of Primary account number (PAN) guarantee that all data is encrypted.
Encrypt Transmitted Data User details are shared across ordinary channels like payment processors, local stores, home office, etc. So, encrypted user data is shared with all these locations. Bank account numbers should never be shared with any unknown locations during card transactions.
Utilize Anti-Virus Software Using anti-virus for PCI DSS compliance is a good practice. So, installing antivirus for all devices interacting with sales locations is essential.
Regularly Updated Software Regular updates of Firewalls and Anti-virus software is important for all software devices. In this way, new security vulnerabilities are taken care of. They add another level of security. These updates are needed for all software that interacts with the user's card.
Restrict Data Access Cardholder's data protection is the prime feature of PCI compliance. Customer care executives and other staff are prohibited to know the card details. Access to sensitive data should be documented and updated regularly.
Unique IDs for Access User credentials can be set up for an executive who has access to user data. Unique ID created for individual users will reduce security vulnerability. This process reduces the response time if a data security breach happens.
Restrict Physical Access Cardholder data must be protected physically and digitally in a secure location. Written data or typed data is to be secured in a room drawer, or cabinet. Limit and control the access time of sensitive data by maintaining a log for compliance.
Maintain Access Logs Develop and maintain log details of the activities related to the cardholder. Lack of records and documentation related to the cardholder creates a security vulnerability. So, documenting the workflow of data sharing while accessing sensitive data in compliance.
Scan and Test for Vulnerabilities The above said compliance needs software products, physical locations, and a few executives. Many of them may malfunction or suffer errors. Regular scans and testing will curtail all the above-said errors.
Document Policies Documentation of inventory equipment, software, and access directory is imperative for compliance. Information workflow, storage, and use at the Point of sale (POS) should be documented.
