The Juniper router must be configured to enforce approved authorizations for controlling the flow of information between interconnected networks in accordance with applicable policy.
<VulnDiscussion>Information flow control regulates authorized information to travel within a network and between interconnected networks. Con...Rule Medium Severity -

The Juniper router configured for Multicast Source Discovery Protocol (MSDP) must filter received source-active multicast advertisements for any undesirable multicast groups and sources.
<VulnDiscussion>The interoperability of BGP extensions for interdomain multicast routing and MSDP enables seamless connectivity of multicast ...Rule Low Severity -
SRG-NET-000018-RTR-000008
<GroupDescription></GroupDescription>Group -
The Juniper router configured for Multicast Source Discovery Protocol (MSDP) must filter source-active multicast advertisements to external MSDP peers to avoid global visibility of local-only multicast sources and groups.
<VulnDiscussion>To avoid global visibility of local information, there are a number of source-group (S, G) states in a PIM-SM domain that mus...Rule Low Severity -

<GroupDescription></GroupDescription>Group -
The Juniper router configured for MSDP must limit the amount of source-active messages it accepts on per-peer basis.
<VulnDiscussion>To reduce any risk of a denial-of-service (DoS) attack from a rogue or misconfigured MSDP router, the router must be configur...Rule Low Severity -
SRG-NET-000018-RTR-000010
<GroupDescription></GroupDescription>Group -
The Juniper router configured for BGP must reject route advertisements from CE routers with an originating AS in the AS_PATH attribute that does not belong to that customer.
<VulnDiscussion>Verifying the path a route has traversed will ensure that the local AS is not used as a transit network for unauthorized traf...Rule Low Severity -

<GroupDescription></GroupDescription>Group -
The Juniper router must be configured to disable the auxiliary port unless it is connected to a secured modem providing encryption and authentication.
<VulnDiscussion>The use of POTS lines to modems connecting to network devices provides clear text of authentication traffic over commercial c...Rule Low Severity -

<GroupDescription></GroupDescription>Group -
The Juniper router must be configured to disable Protocol Independent Multicast (PIM) on all interfaces that are not required to support multicast routing.
<VulnDiscussion>If multicast traffic is forwarded beyond the intended boundary, it is possible that it can be intercepted by unauthorized or ...Rule Medium Severity -
SRG-NET-000019-RTR-000004
<GroupDescription></GroupDescription>Group -
The Juniper router must be configured to bind a Protocol Independent Multicast (PIM) neighbor filter to interfaces that have PIM enabled.
<VulnDiscussion>PIM is a routing protocol used to build multicast distribution trees for forwarding multicast traffic across the network infr...Rule Medium Severity -

<GroupDescription></GroupDescription>Group -
The Juniper multicast edge router must be configured to establish boundaries for administratively scoped multicast traffic.
<VulnDiscussion>If multicast traffic is forwarded beyond the intended boundary, it is possible that it can be intercepted by unauthorized or ...Rule Low Severity -

The Juniper router must be configured to have all inactive interfaces disabled.
<VulnDiscussion>An inactive interface is rarely monitored or controlled and may expose a network to an undetected attack on that interface. U...Rule Low Severity
