Therefore, reviewing all default settings and using strong passwords is essential for a secure configuration.”Ī. These default settings can pose a potential risk to the device’s security.įor example, critical settings like the administrator password can make it easier for malicious actors to gain access to the device. “A critical step for the security of POS devices is to modify default configurations. When conducting a security review of a POS device’s configuration, it is crucial to carefully examine all default configuration settings and other essential parameters to ensure that they are properly configured.įor instance, the following example highlights the default administrator password, which may vary depending on the device’s brand and model: POS devices typically come with default configurations, and it is necessary to change these default settings before deploying them in a production environment.ĭefault configurations may encompass device access management, encryption methods, and default settings for services such as FTP and SSH. This may include checking if the device is running up-to-date software and firmware versions, changing default passwords, disabling unnecessary network connections, and reviewing firewall settings. This step involves ensuring that the POS device is correctly configured and has appropriate security settings. How do I conduct a point-of-sale (POS) Device Security Test ? A. The ATM key encrypts and sends this response back to the POS device. Step F : Transaction Completion When the transaction is successfully completed, the CBS server generates a response. The deducted amount is transferred to the seller’s account. Step E : Account Verification and Fund Transfer The CBS server checks the balance in the cardholder’s account and deducts the purchase amount. The NFS server forwards the transaction to the HSM server of the other bank for PIN verification.Īfter successful verification, the transaction is sent to the CBS server. ![]() Step D : Different Bank Scenario If the card belongs to a different bank, the transaction is routed to the NFS server. After successful verification, the transaction request is forwarded to the CBS server. Step C : Card Verification If the card belongs to the same bank, the ATM key verifies the PIN using the Hardware Security Module (HSM) server. Network Access Control (NAC) ensures secure access. Step B : POS Device Initiates the Transaction The POS device initiates the transaction by securely transmitting card details and the PIN code, encrypted, to the ATM Switch server. Step A : The Customer Uses the Card The customer initiates the payment process by inserting their card into the POS device and entering their confidential PIN code.
