|
V-214535
|
Medium |
The Juniper SRX Services Gateway Firewall must deny network communications traffic by default and allow network communications traffic by exception (i.e., deny all, permit by exception). |
A deny-all, permit-by-exception network communications traffic policy ensures that only those connections which are essential and approved are allowed.
As a managed interface, the ALG must block all inbound and outbound network communications traffic to the application being managed and controlled unless a policy filter is installed to explicitly allow... |
|
V-214534
|
Medium |
The Juniper SRX Services Gateway Firewall must be configured to fail securely in the event of an operational failure of the firewall filtering or boundary protection function. |
If a boundary protection device fails in an unsecure manner (open), information external to the boundary protection device may enter, or the device may permit unauthorized information release.
Secure failure ensures when a boundary control device fails, all traffic will be subsequently denied.
Fail secure is a condition achieved by... |

|
V-214532
|
Medium |
The Juniper SRX Services Gateway Firewall must block outbound traffic containing known and unknown denial-of-service (DoS) attacks to protect against the use of internal information systems to launch any DoS attacks against other networks or endpoints. |
DoS attacks can take multiple forms but have the common objective of overloading or blocking a network or host to deny or seriously degrade performance. If the network does not provide safeguards against DoS attack, network resources will be unavailable to users. The Juniper SRX must include protection against DoS... |
|
V-214530
|
Medium |
The Juniper SRX Services Gateway Firewall must implement load balancing on the perimeter firewall, at a minimum, to limit the effects of known and unknown types of denial-of-service (DoS) attacks on the network. |
If the network does not provide safeguards against DoS attacks, network resources will be unavailable to users. Load balancing provides service redundancy, which reduces the susceptibility of the ALG to many DoS attacks.
This requirement applies to the network traffic functionality of the device as it pertains to handling network... |
|
V-214528
|
Medium |
The Juniper SRX Services Gateway Firewall must terminate all communications sessions associated with user traffic after 15 minutes or less of inactivity. |
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... |
