Risk Management
“If we guard our toothbrushes
and diamonds with equal zeal, we will
lose fewer toothbrushes and more
diamonds.”
-McGeorge Bundy, National Security Advisor to U.S.
Presidents Kennedy and Johnson

Risk can never be eliminated and so it must be
MANAGED!!
Managing risk doesn’t mean
fixing everything,
nor does it mean
not fixing anything…
Risk Management
is about
knowledge and understanding!

Security Control Structure – Revision 5
AU-4 AUDIT LOG STORAGE CAPACITY
Control: Allocate audit log storage capacity to accommodate [Assignment: organization-
defined audit log retention requirements].
Discussion: Organizations consider the types of audit logging to be performed and the audit
log processing requirements when allocating audit log storage capacity. Allocating
sufficient audit log storage capacity reduces the likelihood of such capacity being exceeded
and resulting in the potential loss or reduction of audit logging capability.
Related controls: AU-2, AU-5, AU-6, AU-7, AU-9, AU-11, AU-12, SI-4.
Control Enhancements:
(1) AUDIT LOG STORAGE CAPACITY | TRANSFER TO ALTERNATE STORAGE
Transfer audit logs [Assignment: organization-defined frequency] to a different system, system
component, or media other than the system or system component conducting the logging.
Supplemental Guidance: This type of transfer, also known as off-loading, is a common process in systems
with limited audit log storage capacity and thus supports availability of the audit logs. The initial audit log
storage is used only in a transitory fashion until the system can communicate with the secondary or alternate
system allocated to audit log storage, at which point the audit logs are transferred. This control
enhancement is similar to AU-9(2) in that the audit logs are transferred to a different entity; however, the
primary purpose of selecting AU-9(2) is to protect the confidentiality and integrity of audit records.
Organizations can select either enhancement to obtain the dual benefit of increased audit log storage
capacity and preserving the confidentiality, integrity, and availability of audit records and logs.
Related controls: None
References: None.

Security Controls are Technology Neutral
 Security controls are intentionally not focused
on any specific technologies
 Security control implementations &
assessment methods will likely vary based
on the technology to which the control is
being applied, e.g.:
 Cloud-based systems
 Mobile systems
 Applications
 Sensors
 “IoT”
