  • AIX root passwords must never be passed over a network in clear text form.

    &lt;VulnDiscussion&gt;Passwords need to be protected at all times, and encryption is the standard method for protecting passwords. If passwords are...

    Group
  • AIX Operating systems must enforce 24 hours/1 day as the minimum password lifetime.

    &lt;VulnDiscussion&gt;Enforcing a minimum password lifetime helps to prevent repeated password changes to defeat the password reuse or history enfo...

    <GroupDescription></GroupDescription>
    Group
  • AIX Operating systems must enforce a 60-day maximum password lifetime restriction.

    &lt;VulnDiscussion&gt;Any password, no matter how complex, can eventually be cracked. Therefore, passwords need to be changed periodically. If the ...

    Group
  • AIX must prohibit password reuse for a minimum of five generations.

    &lt;VulnDiscussion&gt;Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute...

  • SRG-OS-000078-GPOS-00046

    <GroupDescription></GroupDescription>
    Group
  • AIX must use Loadable Password Algorithm (LPA) password hashing algorithm.

    &lt;VulnDiscussion&gt;The default legacy password hashing algorithm, crypt(), uses only the first 8 characters from the password string, meaning th...

    <GroupDescription></GroupDescription>
    Group
  • AIX must enforce a minimum 15-character password length.

    &lt;VulnDiscussion&gt;The shorter the password, the lower the number of possible combinations that need to be tested before the password is comprom...

  • SRG-OS-000266-GPOS-00101

    <GroupDescription></GroupDescription>
    Group
  • AIX must enforce password complexity by requiring that at least one special character be used.

    &lt;VulnDiscussion&gt;Use of a complex password helps to increase the time and resources required to compromise the password. Password complexity o...

    <GroupDescription></GroupDescription>
    Group
  • AIX must implement a way to force an identified temporary user to renew their password at next login.

    &lt;VulnDiscussion&gt;Without providing this capability, an account may be created without a password. Non-repudiation cannot be guaranteed once an...

  • SRG-OS-000480-GPOS-00225

    <GroupDescription></GroupDescription>
    Group
  • AIX must prevent the use of dictionary words for passwords.

    &lt;VulnDiscussion&gt;If the operating system allows the user to select passwords based on dictionary words, then this increases the chances of pas...

    <GroupDescription></GroupDescription>
    Group
  • The password hashes stored on AIX system must have been generated using a FIPS 140-2 approved cryptographic hashing algorithm.

    &lt;VulnDiscussion&gt;Systems must employ cryptographic hashes for passwords using the SHA-2 family of algorithms or FIPS 140-2 approved successors...

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.
