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.
This requirement addresses concurrent sessions for administrative accounts and does not address concurrent sessions by a single administrator via multiple administrative accounts. The maximum number of concurrent sessions should be defined based upon mission needs and the operational environment for each system. At a minimum, limits must be set for SSH, HTTPS, account of last resort, and root account sessions.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>DPMS Target Juniper Router NDMDISADPMS TargetJuniper Router NDM4034SV-101193V-91093CCI-000054Configure the router to limit the number of concurrent sessions as shown in the example below:
[edit system services]
set ssh connection-limit 2
set ssh max-sessions-per-connection 1Note: This requirement is not applicable to file transfer actions such as SCP and SFTP.
Review the router configuration to determine if concurrent SSH sessions are limited as show in the example below:
system {

connection-limit 2;
}
}
Note: the max-sessions-per-connection must be set to 1 to limit the number of sessions per connection which is limited by the connection-limit.

If management information flow is not enforced based on approved authorizations, the network device may become compromised. Information flow control regulates where management information is allowed to travel within a network device. The flow of all management information must be monitored and controlled so it does not introduce any unacceptable risk to the network device or data.
Application-specific examples of enforcement occur in systems that employ rule sets or establish configuration settings that restrict information system services or message-filtering capability based on message content (e.g., implementing key word searches or using document characteristics).
Applications providing information flow control must be able to enforce approved authorizations for controlling the flow of management information within the system in accordance with applicable policy.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>DPMS Target Juniper Router NDMDISADPMS TargetJuniper Router NDM4034SV-101203V-91103CCI-001368Step 1: Configure the router to restrict management access to specific IP addresses via SSH as shown in the example below.
[edit firewall family inet]
set filter RESTRICT_MGMT_ACCESS term ALLOW_SSH from source-address x.x.x.x/24
set filter RESTRICT_MGMT_ACCESS term ALLOW_SSH from protocol tcp
set filter RESTRICT_MGMT_ACCESS term ALLOW_SSH from port ssh
set filter RESTRICT_MGMT_ACCESS term ALLOW_SSH then accept
set filter RESTRICT_MGMT_ACCESS term DENY_SSH from protocol tcp
set filter RESTRICT_MGMT_ACCESS term DENY_SSH from port ssh
set filter RESTRICT_MGMT_ACCESS term DENY_SSH then log
set filter RESTRICT_MGMT_ACCESS term DENY_SSH then discard
Step 2: Apply the filter to the loopback interface.
[edit interfaces lo0 unit 0 family inet]
set filter input RESTRICT_MGMT_ACCESS
Note: Management and control plane traffic destined to the router is punted to the routing engine. Hence, applying the filter to the loopback ensures that this traffic can be monitored regardless of the ingress physical interface.
Step 1: Configure the router to restrict management access to specific IP addresses via SSH as shown in the example below.
[edit firewall family inet]
set filter RESTRICT_MGMT_ACCESS term ALLOW_SSH from source-address x.x.x.x/24
set filter RESTRICT_MGMT_ACCESS term ALLOW_SSH from protocol tcp
set filter RESTRICT_MGMT_ACCESS term ALLOW_SSH from port ssh
set filter RESTRICT_MGMT_ACCESS term ALLOW_SSH then accept
set filter RESTRICT_MGMT_ACCESS term DENY_SSH from protocol tcp
set filter RESTRICT_MGMT_ACCESS term DENY_SSH from port ssh
set filter RESTRICT_MGMT_ACCESS term DENY_SSH then log
set filter RESTRICT_MGMT_ACCESS term DENY_SSH then discard
Step 2: Apply the filter to the loopback interface.
[edit interfaces lo0 unit 0 family inet]
set filter input RESTRICT_MGMT_ACCESS
Note: Management and control plane traffic destined to the router is punted to the routing engine. Hence, applying the filter to the loopback ensures that this traffic can be monitored regardless of the ingress physical interface.Review the router configuration to verify that it is compliant with this requirement.
Step 1: Verify that an input filter has been configured for the loopback interfaces as shown in the example below.
interfaces {
…
…
…
}
lo0 {
unit 0 {
family inet {
filter {
input RESTRICT_MGMT_ACCESS;
}
address 2.2.2.2/32;
}
}
}
}
Step 2: Verify that the filter restricts management traffic. The configuration example below restricts management access to specific IP addresses via SSH.
filter RESTRICT_MGMT_ACCESS {
term ALLOW_SSH {
from {
source-address {
x.x.x.x/24;
}
protocol tcp;
port ssh;
}
then accept;
}
term DENY_SSH {
from {
protocol tcp;
port ssh;
}
then {
log;
discard;
}
}
}
Note: Management and control plane traffic destined to the router is punted to the routing engine. Hence, applying the filter to the loopback ensures that this traffic can be monitored regardless of the ingress physical interface.

This requirement addresses the configuration of network devices to mitigate the impact of DoS attacks that have occurred or are ongoing on device availability. For each network device, known and potential DoS attacks must be identified and solutions for each type implemented. A variety of technologies exist to limit or, in some cases, eliminate the effects of DoS attacks (e.g., limiting processes or restricting the number of sessions the device opens at one time). Employing increased capacity and bandwidth, combined with service redundancy, may reduce the susceptibility to some DoS attacks.
The security safeguards cannot be defined at the DoD level because they vary according to the capabilities of the individual network devices and the security controls applied on the adjacent networks (for example, firewalls performing packet filtering to block DoS attacks).</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>DPMS Target Juniper Router NDMDISADPMS TargetJuniper Router NDM4034SV-101273V-91173CCI-002385Configure the router protect against known types of DoS attacks on the route processor.

Step 1: Configure policers for specific traffic types.

Step 2: Configure the authentication order to use the authentication server as primary source for authentication as shown in the following example:

Note: If there is no response from the authentication server, JUNOS will authenticate using a local account as last resort. It is recommended to not configure password at the end of the authentication order, as JUNOS will attempt to authenticate using a local account upon a rejection from the authentication server.Review the router configuration to verify that the device is configured to use an authentication server as primary source for authentication as shown in the following example:
