Please consult the documentation that came with your remote access software or solution. ### Guidelines Here are some guidelines that will help securing remote access: * Change default settings in the remote access software (for example, change default passwords and use unique passwords for each customer). * Allow connections only from specific (known) IP/MAC addresses. (Also known as MAC Address Filtering) * Use strong authentication and complex passwords for logins (See PA-DSS Requirements 3.1.1 through 3.1.10) * Enable encrypted data transmission according to PA-DSS Requirement 12.1 * Enable account lockout after a certain number of failed login attempts (See PADSS Requirement 3.1.8) * Configure the system so a remote user must establish a Virtual Private Network (“VPN”) connection via a firewall before access is allowed. * Enable the logging function. * Restrict access to customer passwords to authorized reseller/integrator personnel. * Establish customer passwords according to PA-DSS Requirements 3.1.1through 3.1.10. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.maitredpos.com/maitred/maitred-pa-dss-implementation-guide/pa-dss-requirement-10.2.3.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
