Group -
For local accounts created on the device, the Juniper SRX Services Gateway must automatically generate log records for account creation events.
Upon gaining access to a network device, an attacker will often first attempt to create a persistent method of reestablishing access. One way to accomplish this is to create a new account. Notifica...Rule Medium Severity -

SRG-APP-000319-NDM-000283
Group -
The Juniper SRX Services Gateway must automatically generate a log event when accounts are enabled.
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...Rule Medium Severity -
SRG-APP-000033-NDM-000212
Group -
The Juniper SRX Services Gateway must enforce the assigned privilege level for each administrator and authorizations for access to all commands by assigning a login class to all AAA-authenticated users.
To mitigate the risk of unauthorized privileged access to the device, administrators must be assigned only the privileges needed to perform the tasked assigned to their roles. Although use of an ...Rule Medium Severity -
SRG-APP-000343-NDM-000289
Group -
The Juniper SRX Services Gateway must generate a log event when privileged commands are executed.
Misuse of privileged functions, either intentionally or unintentionally by authorized users, or by unauthorized external entities that have compromised information system accounts, is a serious and...Rule Low Severity -
SRG-APP-000065-NDM-000214
Group -
For local accounts created on the device, the Juniper SRX Services Gateway must enforce the limit of three consecutive invalid logon attempts by a user during a 15-minute time period.
By limiting the number of failed logon attempts, the risk of unauthorized system access via user password guessing, otherwise known as brute-forcing, is reduced. Juniper SRX is unable to comply wi...Rule Low Severity -
SRG-APP-000068-NDM-000215
Group -
The Juniper SRX Services Gateway must display the Standard Mandatory DoD Notice and Consent Banner before granting access.
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, Executi...Rule Low Severity -
SRG-APP-000091-NDM-000223
Group -
The Juniper SRX Services Gateway must generate log records when successful attempts to configure the device and use commands occur.
Without generating log records, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one. While the Juniper SRX inhe...Rule Low Severity -
SRG-APP-000495-NDM-000318

SRG-APP-000101-NDM-000231
Group -
The Juniper SRX Services Gateway must generate log records containing the full-text recording of privileged commands.
Reconstruction of harmful events or forensic analysis is not possible if log records do not contain enough information. Organizations consider limiting the additional audit information to only th...Rule Low Severity -
SRG-APP-000357-NDM-000293
Group -
For local log files, the Juniper SRX Services Gateway must allocate log storage capacity in accordance with organization-defined log record storage requirements so that the log files do not grow to a size that causes operational issues.
In order to ensure network devices have a sufficient storage capacity in which to write the logs, they need to be able to allocate audit record storage capacity. The task of allocating audit record...Rule Medium Severity -
SRG-APP-000360-NDM-000295
Group -
The Juniper SRX Services Gateway must generate an immediate system alert message to the management console when a log processing failure is detected.
It is critical for the appropriate personnel to be aware if a system is at risk of failing to process logs as required. Without an immediate alert for critical system issues, security personnel may...Rule Medium Severity -
SRG-APP-000374-NDM-000299
Group -
The Juniper SRX Services Gateway must record time stamps for log records using Coordinated Universal Time (UTC).
If time stamps are not consistently applied and there is no common time reference, it is difficult to perform forensic analysis. UTC is normally used in DoD; however, Greenwich Mean Time (GMT) may ...Rule Medium Severity -
SRG-APP-000378-NDM-000302
Group -
The Juniper SRX Services Gateway must implement logon roles to ensure only authorized roles are allowed to install software and updates.
Allowing anyone to install software, without explicit privileges, creates the risk that untested or potentially malicious software will be installed on the system. This requirement applies to code ...Rule Medium Severity -
SRG-APP-000516-NDM-000317
Group -
If the loopback interface is used, the Juniper SRX Services Gateway must protect the loopback interface with firewall filters for known attacks that may exploit this interface.
The loopback interface is a logical interface and has no physical port. Since the interface and addresses ranges are well-known, this port must be filtered to protect the Juniper SRX from attacks.Rule Medium Severity -

Group -
The Juniper SRX Services Gateway must be configured to synchronize internal information system clocks with the primary and secondary NTP servers for the network.
