Q1: Block new connections, Redirect traffic to a designated server, Trigger an alert or notification.

Q2: True

Q3: Stateful Inspection & Behavioral Analysis

Q4: Backups, Testing, Staged Rollout, Monitoring & Verification.

Q1: If the number of new connections exceeds the specified threshold, actions such as giving alerts, discarding sessions, and blocking IP addresses can be executed
Q2: Right, DDNS policies can be configured to automatically map a user's dynamic IP address to a permanent domain name. Users do not need to update the mapping between IP addresses and domain names manually.
Q3: 1. Detection objects: multiple NICs, wireless NICs, and 4G/5G NICs. 2. Detection methods: immediate detection and scheduled detection.
Q4: Normal condition when at least 40% of the total CPU and memory are available, and the network is connected

Q1: giving alerts, discarding sessions, blocking IP adress
Q2: it is right
Q3: immediate detection and scheduled detection
Q4: The upgrade process may take about 20 minutes under normal conditions (at least 40% of the total CPU and memory are available, and the network is connected).

Q1:  If the number of new connections exceeds the specified threshold, actions such as giving alerts, discarding sessions, and blocking IP addresses can be executed.
Q2: Right/True
Q3: 1. Detection objects: multiple NICs, wireless NICs, and 4G/5G NICs.
       2. Detection methods: immediate detection and scheduled detection.
Q4: The upgrade process may take about 20 minutes under normal conditions (at least 40% of the total CPU and memory are available, and the network is connected)

Q1 : giving alerts, discarding sessions, and blocking IP addresses
Q2 : yes it is right
Q3 : immediate detection and scheduled detection
Q4 :

Q1. Alert generation, Connection throttling or rate limiting, Blocking or dropping connections.
Q2. true.
Q3. Traffic analysis and Signature-based detection
Q4. No active errors in the system before the upgrade, Sufficient resource availability, Stable network connection for downloading and applying the upgrade.

Q # 1
1. Trigger an alert notification to the system administrator to inform them of the increased number of new connections exceeding the threshold, allowing for timely intervention to mitigate potential risks and optimize network performance.

2. Implement an automatic traffic analysis to identify the source of the excessive new connections and apply specific firewall rules or access control policies to restrict or block suspicious traffic patterns, enhancing network security and maintaining optimal operation.

3. Utilize load balancing algorithms to distribute the load of incoming connections across multiple servers or network resources in order to prevent overload on any single component, ensuring consistent availability and performance even during peak connection periods.

Q # 2
In the SANGFOR_NSF_V8.0.95 version, users do not need to update the mapping between IP addresses and domain names manually. This statement is true. The SANGFOR Next-Generation Firewall V8.0.95 version comes with enhanced features that automate the process of mapping IP addresses to domain names without requiring manual intervention from users. This advancement in the software eliminates the need for users to constantly update this mapping, saving time and effort in network management tasks. With this automated feature, users can ensure that their network resources are efficiently utilized without the hassle of manual updates, enhancing overall network performance and efficiency.

Q # 3

- Network Behavior Analysis (NBA): This method monitors network traffic to identify unusual patterns that may indicate unauthorized outbound access. By analyzing traffic behavior, NBA can detect potential security threats and alert administrators ¹.

- User Entity Behavior Analytics (UEBA): UEBA focuses on monitoring user activity to identify suspicious behavior. By analyzing user behavior, UEBA can detect unauthorized outbound access attempts and alert administrators.

Additionally, you can also consider implementing:

- Intrusion Detection Systems (IDS): IDS can detect unauthorized access attempts by monitoring network traffic for malicious activity ¹.

- Anomaly-based Detection: This method identifies unusual traffic patterns that deviate from established baselines.

To effectively detect unauthorized outbound access, it's essential to combine these methods and regularly monitor network activity.

Q # 4

The normal condition for the upgrade process involves ensuring that a proper backup of the existing configuration and data is taken before initiating the upgrade. It is crucial to verify the compatibility of the new version with the existing hardware and software components to prevent any potential conflicts. Additionally, conducting thorough testing in a controlled environment prior to deploying the upgrade in the production environment is a recommended best practice. Adequate resources such as time, personnel, and communication channels should be allocated to facilitate a smooth transition during the upgrade process. Proper documentation of the upgrade steps and any potential issues encountered, along with a rollback plan in case of unforeseen circumstances, is essential for effective risk management. Finally, engaging with vendor support and relevant user communities for guidance and assistance during the upgrade can help address any challenges that may arise, ensuring a successful and efficient upgrade process.
