SRG-NET-000213
Group -
The Juniper SRX Services Gateway VPN must terminate all network connections associated with a communications session at the end of the session.
Idle TCP sessions can be susceptible to unauthorized access and hijacking attacks. IKE Dead Peer Detection (DPD) is a protocol that verifies the availability of IPsec peer devices by sending encryp...Rule Medium Severity -
SRG-NET-000352
Group -
The Juniper SRX Services Gateway VPN Internet Key Exchange (IKE) must be configured to use an approved Commercial Solution for Classified (CSfC) when transporting classified traffic across an unclassified network.
Use of weak or untested encryption algorithms undermines the purposes of using encryption to protect data. The National Security Agency/Central Security Service's (NSA/CSS) CSfC Program enables co...Rule High Severity -
SRG-NET-000510
Group -
The Juniper SRX Services Gateway VPN IKE must use NIST FIPS-validated cryptography to implement encryption services for unclassified VPN traffic.
Use of weak or untested encryption algorithms undermines the purposes of using encryption to protect data. The network element must implement cryptographic modules adhering to the higher standards ...Rule Medium Severity -
SRG-NET-000230
Group -
The Juniper SRX Services Gateway VPN must configure Internet Key Exchange (IKE) with SHA1 or greater to protect the authenticity of communications sessions.
Authenticity protection provides protection against man-in-the-middle attacks/session hijacking and the insertion of false information into sessions. This requirement focuses on communications pro...Rule High Severity -
SRG-NET-000355
Group -
The Juniper SRX Services Gateway VPN must only allow the use of DoD PKI established certificate authorities for verification of the establishment of protected sessions.
Untrusted certificate authorities (CA) can issue certificates, but they may be issued by organizations or individuals that seek to compromise DoD systems or by organizations with insufficient secur...Rule Medium Severity -
SRG-NET-000364
Group -
The Juniper SRX Services Gateway VPN must only allow incoming VPN communications from organization-defined authorized sources routed to organization-defined authorized destinations.
Unrestricted traffic may contain malicious traffic which poses a threat to an enclave or to other connected networks. Additionally, unrestricted traffic may transit a network, which uses bandwidth ...Rule Medium Severity -
SRG-NET-000369
Group -
The Juniper SRX Services Gateway VPN must disable split-tunneling for remote clients VPNs.
Split tunneling would in effect allow unauthorized external connections, making the system more vulnerable to attack and to exfiltration of organizational information. A VPN hardware or software c...Rule Medium Severity -
SRG-NET-000147
Group -
The Juniper SRX Services Gateway VPN must use anti-replay mechanisms for security associations.
Anti-replay is an IPsec security mechanism at a packet level which helps to avoid unwanted users from intercepting and modifying an ESP packet. The SRX adds a sequence number to the ESP encapsulat...Rule Medium Severity
