static attack object groups are predefined groups of attack objects that are included in Juniper’s IPS signature database. These groups do not change automatically when Juniper updates the database2.

you need to create a global firewall rulebase that matches RT_FLOW_SESSION_DENY events2. To do this, you need to specify two policy parameters: deny and session-close3. 

JIMS server is a Juniper Identity Management Service that collects user identity information from different authentication sources for SRX Series devices12. It can connect to SRX Series devices and CSO platform in your network1.  JIMS server is a service that protects corporate resources by authenticating and restricting user access based on roles2. It connects to SRX Series devices and CSO platform to provide identity information for firewall policies1. To reduce the load that JIMS server places on your network, you should connect JIMS to another SRX Series device1. This way, you can distribute the identity information among multiple SRX Series devices and reduce network traffic.

unified security policies are security policies that enable you to use dynamic applications as match conditions along with existing 5-tuple or 6-tuple matching conditions12. They simplify applicationbased security policy management at Layer 7 and provide greater control and extensibility to manage dynamic applications traffic3

1. Client protection proxy: This statement is correct because a forward proxy can also be called a client protection proxy since it protects the user’s identity and computer information from the web server4. 2. Server protection proxy: This statement is correct because a reverse proxy can also be called a server protection proxy since it protects the web server’s identity and location from the user4.

You have exceeded the maximum files submission for your SRX platform size: This statement is correct because file scanning on SRX300 Series device has a limit on the number of files that can be submitted per minute based on the platform size3. For example, SRX320 has a limit of 10 files per minute3.

1. Chassis cluster member devices synchronize configuration using the control link: This statement is correct because the control link is used for configuration synchronization among other functions. 2. A control link failure causes the secondary cluster node to be disabled: This statement is correct because a control link failure causes the secondary node to become ineligible for primary role and remain in secondary role until the control link is restored.  3. Heartbeat messages verify that the chassis cluster control link is working: This statement is correct because heartbeat messages are sent periodically over the control link to monitor its status.

policy rematch is a feature that enables the device to reevaluate an active session when its associated security policy is modified. The session remains open if it still matches the policy that allowed the session initially. The session is closed if its associated policy is renamed, deactivated, or deleted1.

you can block applications and users based on network access policies, users and their job roles, time, and application signatures2. You can also use Juniper Advanced Threat Prevention (ATP) to find and block commodity and zero-day cyberthreats within files, IP traffic, and DNS requests1

Infected hosts are internal hosts that have been compromised by malware and are communicating with external C&C servers3. Juniper ATP Cloud provides infected host feeds that list internal IP addresses or subnets of infected hosts along with a threat level3. Once the Juniper ATP Cloud global threshold for an infected host is met, that host is added to the infected host feed and assigned a threat level of 10 by the cloud4. You can also configure your SRX Series device to block traffic from these IP addresses using security policies4.
