![]() ![]() Regardless of how secure the system is otherwise, the system is now highly vulnerable and at risk: security configurations can be altered to allow broader access, software can be installed, new accounts can be created, etc. If the username and password of a system are already known, the attacker-whether an outside entity or an internal user-can simply and easily authenticate, often with administrative privileges since most default accounts exist for the purpose of initial setup and configuration of other user accounts. The initial stages of most attacks involve the enumeration of legitimate system and user identities, a process that is necessary to determine vulnerabilities so that an exploit can be attempted (see Chapter 6, “Vulnerability and Risk Assessment”). The use of default accounts and passwords is common and dangerous.

If your company has not changed its new user process globally to reflect the more stringent requirements for users with access to cardholder data, you may end up with some users that have generic passwords. Before PCI DSS required otherwise, many system administrators used the same generic password for all new users. If you can remember back to when you first received your user ID and password, you might recall that it was a preset generic password (does Password123 or Welcome1 sound familiar?). ![]() Although there are several alternatives for authentication like biometrics, smart cards, and tokens, most of us use the traditional user ID and password.Īdditionally, if your organization has a procedure for adding new users and granting them access to systems, there may be some default passwords that you haven’t thought about. Password policies and procedures are usually dictated by the organization. Requirement 2.1.1 imposes the same mandate for wireless environments. Requirement 2.1 states that all vendor-supplied passwords must be changed before deploying a system on the network.
