Requires approvals by Assignment: organization-defined personnel or roles for requests to create information system accounts;. Creates, enables, modifies, disables, and removes information system accounts in accordance with Assignment: organization-defined procedures or conditions ;.

Reviews accounts for compliance with account management requirements Assignment: organization-defined frequency ; and. AC-2 1 Automated System Account Management MODERATE The use of automated mechanisms can include, for example: using email or text messaging to automatically notify account managers when users are terminated or transferred; using the information system to monitor account usage; and using telephonic notification to report atypical system account usage.

AC-2 5 Inactivity Logout HIGH The organization requires that users log out when Assignment: organization-defined time-period of expected inactivity or description of when to log out. AC-2 6 Dynamic Privilege Management In contrast to conventional access control approaches which employ static information system accounts and predefined sets of user privileges, dynamic access control approaches e. Dynamic privilege management can include, for example, the immediate revocation of privileges from users, as opposed to requiring that users terminate and restart their sessions to reflect any changes in privileges.

Dynamic privilege management can also refer to mechanisms that change the privileges of users based on dynamic rules as opposed to editing specific user profiles. This type of privilege management includes, for example, automatic adjustments of privileges if users are operating out of their normal work times, or if information systems are under duress or in emergency maintenance situations. This control enhancement also includes the ancillary effects of privilege changes, for example, the potential changes to encryption keys used for communications.

Dynamic privilege management can support requirements for information system resiliency. AC-2 7 Role-Based Schemes Privileged roles are organization-defined roles assigned to individuals that allow those individuals to perform certain security-relevant functions that ordinary users are not authorized to perform.

These privileged roles include, for example, key management, account management, network and system administration, database administration, and web administration. The organization: AC-2 7 a Establishes and administers privileged user accounts in accordance with a role-based access scheme that organizes allowed information system access and privileges into roles; AC-2 7 b Monitors privileged role assignments; and AC-2 7 c Takes Assignment: organization-defined actions when privileged role assignments are no longer appropriate.

Organizations plan for dynamic creation of information system accounts by establishing trust relationships and mechanisms with the appropriate authorities to validate related authorizations and privileges.

Ozbakir , Publication Date Web : August 22, Lizhou Xu , Publication Date Web : December 1, About 3D Secure authentication 3D Secure is an authentication protocol for online credit card payments, and it has been the de facto authentication standard since the year How it works.

The capital "D" in "3D Secure" stands for "domain", and there are 3 of them: the acquiring domain, the issuing domain, as well as the interoperability domain to link the two together. Issuing domain. The issuing domain is where the issuing banks operate.

They are the ones who issue cards to cardholders, who then use the card to purchase goods and services. The issuing bank needs to deploy an Access Control Server, also known as "ACS", in order to receive 3D Secure messages, process the messages, and authenticate the card user.

Interoperability domain. The interoperability domain consists of just the Directory Server, which is deployed by card schemes, and can be considered the glue between the acquiring and issuing domains. If a merchant wants to authenticate a credit card and its user, how do they know which issuing bank to contact? The answer is simple: they send a message to the card scheme's Directory Server, which holds a "directory" of all the BIN ranges corresponding issuing banks. The Directory Server will receive the message from the MPI, check the card number against the BIN range directory that it holds, and forward that message onto the correct issuing bank.

The issuing bank would then proceed with authenticating the card user.
