V-246959
|
High |
ONTAP must terminate all network connections associated with a device management session at the end of the session, or the session must be terminated after 10 minutes of inactivity except to fulfill documented and validated mission requirements. |
Terminating an idle session within a short time period reduces the window of opportunity for unauthorized personnel to take control of a management session enabled on the console or console port that has been left unattended. In addition, quickly terminating an idle session will also free up resources committed by... |
|
V-246958
|
High |
ONTAP must be configured to implement cryptographic mechanisms using FIPS 140-2. |
Unapproved mechanisms that are used for authentication to the cryptographic module are not verified and therefore cannot be relied upon to provide confidentiality or integrity, and DoD data may be compromised.
Satisfies: SRG-APP-000412-NDM-000331, SRG-APP-000411-NDM-000330, SRG-APP-000179-NDM-000265 |

V-246946
|
High |
ONTAP must be configured to prohibit the use of all unnecessary and/or nonsecure functions, ports, protocols, and/or services. |
In order to prevent unauthorized connection of devices, unauthorized transfer of information, or unauthorized tunneling (i.e., embedding of data types within data types), organizations must disable unused or unnecessary physical and logical ports/protocols on information systems.
Network devices are capable of providing a wide variety of functions and services. Some... |
|
V-246940
|
High |
ONTAP must be configured to use an authentication server to provide multifactor authentication. |
Centralized management of authentication settings increases the security of remote and nonlocal access methods. This control is particularly important protection against the insider threat. With robust centralized management, audit records for administrator account access to the organization's network devices can be more readily analyzed for trends and anomalies. The alternative... |
|
V-246930
|
High |
ONTAP must prevent non-privileged users from executing privileged functions to include disabling, circumventing, or altering implemented security safeguards/countermeasures. |
Preventing non-privileged users from executing privileged functions mitigates the risk that unauthorized individuals or processes may gain unnecessary access to information or privileges.
Privileged functions include, for example, establishing accounts, performing system integrity checks, or administering cryptographic key management activities. Non-privileged users are individuals that do not possess appropriate authorizations. |
|
V-246927
|
High |
ONTAP must enforce administrator privileges based on their defined roles. |
To mitigate the risk of unauthorized access to sensitive information by entities that have been issued certificates by DoD-approved PKIs, all DoD systems must be properly configured to incorporate access control methods that do not rely solely on the possession of a certificate for access. Successful authentication must not automatically... |
|
V-246955
|
Medium |
ONTAP 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 resisting attempts at guessing and brute-force attacks.
Password complexity is one factor of several that determine how long it... |

ONTAP must enforce a minimum 15-character password length. |
Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. Password length is one factor of several that helps to determine strength and how long it takes to crack a password.
The shorter the password, the lower the number... |
|
V-246950
|
Medium |
ONTAP must authenticate NTP sources using authentication that is cryptographically based. |
If Network Time Protocol (NTP) is not authenticated, an attacker can introduce a rogue NTP server. This rogue server can then be used to send incorrect time information to network devices, which will make log timestamps inaccurate and affect scheduled actions. NTP authentication is used to prevent this tampering by... |
|
V-246949
|
Medium |
ONTAP must be configured to authenticate SNMP messages using FIPS-validated Keyed-HMAC. |
Without authenticating devices, unidentified or unknown devices may be introduced, thereby facilitating malicious activity. Bidirectional authentication provides stronger safeguards to validate the identity of other devices for connections that are of greater risk.
A local connection is any connection with a device communicating without the use of a network. A... |
|
V-246948
|
Medium |
ONTAP must implement replay-resistant authentication mechanisms for network access to privileges accounts. |
A replay attack may enable an unauthorized user to gain access to the application. Authentication sessions between the authenticator and the application validating the user credentials must not be vulnerable to a replay attack.
An authentication process resists replay attacks if it is impractical to achieve a successful authentication by... |
|
V-246947
|
Medium |
ONTAP must be configured to authenticate each administrator prior to authorizing privileges based on assignment of group or role. |
To assure individual accountability and prevent unauthorized access, administrators must be individually identified and authenticated.
Individual accountability mandates that each administrator is uniquely identified. A group authenticator is a shared account or some other form of authentication that allows multiple unique individuals to access the network device using a single... |
|
V-246945
|
Medium |
ONTAP must use DoD-approved PKI rather than proprietary or self-signed device certificates. |
Each organization obtains user certificates from an approved, shared service provider as required by OMB policy. For federal agencies operating a legacy public key infrastructure cross-certified with the Federal Bridge Certification Authority (CA) at medium assurance or higher, this CA will suffice. |
|
V-246944
|
Medium |
ONTAP must be configured to conduct backups of system level information. |
System-level information includes default and customized settings and security attributes, including ACLs that relate to the network device configuration, as well as software required for the execution and operation of the device. Information system backup is a critical step in ensuring system integrity and availability. If the system fails and... |
|
V-246939
|
Medium |
ONTAP must enforce access restrictions associated with changes to the device configuration. |
Failure to provide logical access restrictions associated with changes to device configuration may have significant effects on the overall security of the system.
When dealing with access restrictions pertaining to change control, it should be noted that any changes to the hardware, software, and/or firmware components of the device could... |
|
V-246938
|
Medium |
ONTAP must record time stamps for audit records that can be mapped to Coordinated Universal Time (UTC) or Greenwich Mean Time (GMT). |
If time stamps are not consistently applied and there is no common time reference, it is difficult to perform forensic analysis.
Time stamps generated by the application include date and time. Time is commonly expressed in Coordinated Universal Time (UTC), a modern continuation of Greenwich Mean Time (GMT), or local... |
|
V-246936
|
Medium |
ONTAP must be configured to synchronize internal information system clocks using redundant authoritative time sources. |
The loss of connectivity to a particular authoritative time source will result in the loss of time synchronization (free-run mode) and increasingly inaccurate time stamps on audit events and other functions.
Multiple time sources provide redundancy by including a secondary source. Time synchronization is usually a hierarchy; clients synchronize time... |
|
V-246935
|
Medium |
ONTAP must have audit guarantee enabled. |
It is critical for the appropriate personnel to be aware if a system is at risk of failing to process audit logs as required. With audit guarantee enabled, all SMB operations must generate an audit event before an ACK is returned to the client and the operation completed. If the... |
|
V-246933
|
Medium |
ONTAP must allocate audit record storage capacity in accordance with organization-defined audit record storage requirements. |
Audit records are stored on staging volumes when auditing is enabled. If the staging volumes do not exist when auditing is enabled, the auditing subsystem creates the staging volumes. These volumes hold the audit logs until they can be consolidated.
Enabling auditing will also enable guaranteed auditing by default. This... |
|
V-246932
|
Medium |
ONTAP must be configured to display the Standard Mandatory DoD Notice and Consent Banner before granting access to the device. |
Display of the DoD-approved use notification before granting access to the network device ensures privacy and security notification verbiage used is consistent with applicable federal laws, Executive Orders, directives, policies, regulations, standards, and guidance.
System use notifications are required only for access via logon interfaces with human users. |
|
V-246931
|
Medium |
ONTAP must be configured to enforce the limit of three consecutive failed logon attempts. |
By limiting the number of failed login attempts, the risk of unauthorized system access via user password guessing, otherwise known as brute-forcing, is reduced. |
|
V-246926
|
Medium |
ONTAP must be configured with only one local account to be used as the account of last resort in the event the authentication server is unavailable. |
Authentication for administrative (privileged-level) access to the device is required at all times. An account can be created on the device's local database for use when the authentication server is down or connectivity between the device and the authentication server is not operable. This account is referred to as the... |
|
V-246925
|
Medium |
ONTAP must automatically audit account-enabling actions. |
Once an attacker establishes initial access to a system, the attacker often attempts to create a persistent method of reestablishing access. One way to accomplish this is for the attacker to simply enable a new or disabled account. Notification of account enabling is one method for mitigating this risk. A... |
|
V-246923
|
Medium |
ONTAP must be configured to create a session lock after 15 minutes. |
A session lock is a temporary network device or administrator-initiated action taken when the administrator stops work but does not log out of the network device. Rather than relying on the user to manually lock their management session prior to vacating the vicinity, network devices need to be able to... |
|
V-246922
|
Medium |
ONTAP must be configured to limit the number of concurrent sessions. |
Device management includes the ability to control the number of administrators and management sessions that manage a device. Limiting the number of allowed administrators and sessions per administrator based on account type, role, or access type is helpful in limiting risks related to DoS attacks. |
