    Group
  • Applications must use system-generated session identifiers that protect against session fixation.

    &lt;VulnDiscussion&gt;Session fixation allows an attacker to hijack a valid user’s application session. The attack focuses on the manner in which a...

    <GroupDescription></GroupDescription>
    Group
  • The application must use the Federal Information Processing Standard (FIPS) 140-2-validated cryptographic modules and random number generator if the application implements encryption, key exchange, digital signature, and hash functionality.

    &lt;VulnDiscussion&gt;Sequentially generated session IDs can be easily guessed by an attacker. Employing the concept of randomness in the generatio...

    <GroupDescription></GroupDescription>
    Group
  • The application must only allow the use of DoD-approved certificate authorities for verification of the establishment of protected sessions.

    &lt;VulnDiscussion&gt;Untrusted Certificate Authorities (CA) can issue certificates, but they may be issued by organizations or individuals that se...

  • SRG-APP-000225

    <GroupDescription></GroupDescription>
    Group
  • The application must fail to a secure state if system initialization fails, shutdown fails, or aborts fail.

    &lt;VulnDiscussion&gt;Failure to a known safe state helps prevent systems from failing to a state that may cause loss of data or unauthorized acces...

  • SRG-APP-000226

    <GroupDescription></GroupDescription>
    Group
  • In the event of a system failure, applications must preserve any information necessary to determine cause of failure and any information necessary to return to operations with least disruption to mission processes.

    &lt;VulnDiscussion&gt;Failure to a known state can address safety or security in accordance with the mission/business needs of the organization. Fa...

    Group
  • The application must protect the confidentiality and integrity of stored information when required by DoD policy or the information owner.

  • SRG-APP-000428

    <GroupDescription></GroupDescription>
    Group
  • The application must implement approved cryptographic mechanisms to prevent unauthorized modification of organization-defined information at rest on organization-defined information system components.

    &lt;VulnDiscussion&gt;Applications handling data requiring "data at rest" protections must employ cryptographic mechanisms to prevent unauthorized ...
