The Mainframe Product must protect audit information from any type of unauthorized read access.
If audit data were to become compromised, then competent forensic analysis and discovery of the true source of potentially malicious system activity is difficult if not impossible to achieve. In ad...Rule Medium Severity -
The Mainframe Product must protect audit information from unauthorized modification.
If audit data were to become compromised, then forensic analysis and discovery of the true source of potentially malicious system activity is impossible to achieve. To ensure the veracity of audi...Rule Medium Severity -
The Mainframe Product must protect audit tools from unauthorized access.
Protecting audit data also includes identifying and protecting the tools used to view and manipulate log data. Therefore, protecting audit tools is necessary to prevent unauthorized operation on au...Rule Medium Severity -
The Mainframe Product must protect audit tools from unauthorized deletion.
Protecting audit data also includes identifying and protecting the tools used to view and manipulate log data. Therefore, protecting audit tools is necessary to prevent unauthorized operation on au...Rule Medium Severity -
The Mainframe Product must prevent the installation of patches, service packs, or application components without verification that the software component has been digitally signed using a certificate that is recognized and approved by the organization.
Changes to any software components can have significant effects on the overall security of the application. Verifying software components have been digitally signed using a certificate that is reco...Rule Medium Severity -
The Mainframe Product must limit privileges to change the Mainframe Product installation datasets to system programmers and authorized users in accordance with applicable access control policies.
If the application were to allow any user to make changes to software libraries, then those changes might be implemented without undergoing the appropriate testing and approvals that are part of a ...Rule Medium Severity -
The Mainframe Product must limit privileges to change Mainframe Product user datasets to authorized individuals.
If the application were to allow any user to make changes to software libraries, then those changes might be implemented without undergoing the appropriate testing and approvals that are part of a ...Rule Medium Severity -
The Mainframe Product must be configured to disable non-essential capabilities.
It is detrimental for applications to provide, or install by default, functionality exceeding requirements or mission objectives. These unnecessary capabilities or services are often overlooked and...Rule Medium Severity -
The Mainframe Product must uniquely identify and authenticate organizational users (or processes acting on behalf of organizational users).
To assure accountability and prevent unauthenticated access, organizational users must be identified and authenticated to prevent potential misuse and compromise of the system. Organizational use...Rule Medium Severity -
The Mainframe Product must use multifactor authentication for network access to non-privileged accounts.
To assure accountability and prevent unauthenticated access, non-privileged users must use multifactor authentication to prevent potential misuse and compromise of the system. Multifactor authent...Rule Medium Severity -
The Mainframe Product must use multifactor authentication for local access to privileged accounts.
To ensure accountability and prevent unauthenticated access, privileged users must use multifactor authentication to prevent potential misuse and compromise of the system. Multifactor authenticat...Rule Medium Severity -
The Mainframe Product must use multifactor authentication for local access to nonprivileged accounts.
To ensure accountability, prevent unauthenticated access, and prevent misuse of the system, nonprivileged users must use multifactor authentication for local access. Multifactor authentication is...Rule Medium Severity -
The Mainframe Product must enforce a minimum 15-character password length.
The shorter the password, the lower the number of possible combinations that need to be tested before the password is compromised. Password complexity, or strength, is a measure of the effectivene...Rule Medium Severity -
The Mainframe Product must enforce password complexity by requiring that at least one lowercase character be used.
Use of a complex password helps to increase the time and resources required to compromise the password. Password complexity, or strength, is a measure of the effectiveness of a password in resistin...Rule Medium Severity -
The Mainframe Product must enforce password complexity by requiring that at least one special character be used.
Use of a complex password helps to increase the time and resources required to compromise the password. Password complexity, or strength, is a measure of the effectiveness of a password in resistin...Rule Medium Severity -
The Mainframe Product must transmit only cryptographically protected passwords.
Passwords need to be protected at all times and encryption is the standard method for protecting passwords. If passwords are not encrypted, they can be plainly read (i.e., clear text) and easily co...Rule Medium Severity -
The Mainframe Product must enforce 24 hours/1 day as the minimum password lifetime.
Enforcing a minimum password lifetime helps prevent repeated password changes to defeat the password reuse or history enforcement requirement. Restricting this setting limits the user's ability to...Rule Medium Severity -
The Mainframe Product must enforce a 60-day maximum password lifetime restriction.
Any password, no matter how complex, can eventually be cracked; therefore, passwords need to be changed at specific intervals. One method of minimizing this risk is to use complex passwords and p...Rule Medium Severity -
The Mainframe Product, when using PKI-based authentication, must validate certificates by constructing a certification path (which includes status information) to an accepted trust anchor.
Without path validation, an informed trust decision by the relying party cannot be made when presented with any certificate not already explicitly trusted. A trust anchor is an authoritative entit...Rule Medium Severity -
The Mainframe Product must obscure feedback of authentication information during the authentication process to protect the information from possible exploitation/use by unauthorized individuals.
To prevent the compromise of authentication information such as passwords during the authentication process, the feedback from the information system must not provide any information that would all...Rule Medium Severity

The content of the drawer really is up to you. It could have form fields, definition lists, text lists, labels, charts, progress bars, etc. Spacing recommendation is 24px margins. You can put tabs in here, and can also make the drawer scrollable.
