A System Administrator begins receiving widespread reports of traffic latency and disruption from users and wants to determine which device in a network is causing the problem.
Which step can the System Administrator take to rule out the XGS?
- A. Clear all active quarantine rules.
- B. Restart the packet processing daemon.
- C. Use the dpi off command to disable inspection.
- D. Ping sample hosts from the command line and note the time.
Answer : C
Question -
How can you bypass inspection on QRadar Network Security (XGS) to troubleshoot issues like latency or the XGS blocking traffic?
Answer -
Starting in firmware 5.3.1.4 and continuing, you have the ability to bypass the inspection engine on the XGS for certain testing scenarios (such as traffic being blocked or latency through the XGS).
All of the analysis is a result of the Protocol Analysis Module (PAM). PAM is responsible for Network Access Policy (NAP) rules, IPS, SSL inspection, URL analysis, and so on. Bypassing PAM allows the traffic to go through unanalyzed to help determine whether the XGS is causing the issue.
To bypass PAM, do the following:
1. SSH to the device and login as admin.
2. Enter analysis to enter the analysis module.
3. To disable PAM, enter the following:
dpi off
You should now see a message that says:
DPI is bypassed.
This setting will be reverted upon next packet processing service restart.

A System Administrator has configured SSL Inspection in XGS, but end users get promoted to verify the certificate in the browser when viewing SSL web pages.
To fix the issue the System Administrator must distribute the CA certificates so that it can be imported in the Trusted Root Certification Authorities in end users"™ browsers.
Which Menu option allows the System Administrator to download the CA Certificate?
- A. Inbound SSL Certificates
- B. Appliance SSL Certificate
- C. Outbound SSL Certificates
- D. Management Certificate Authorities
Answer : C
In order for Outbound SSL to work properly, the XGS Certificate Authority (CA) certificate must be installed in the browser in order for the browser to verify the identity of the XGS. If you do not add the CA certificate, Outbound SSL will not work properly, introduce latency, and could cause pages to fail to load.
If users get prompted to verify the certificate in the browser when viewing SSL web pages, this indicates that the CA is not loaded or is loaded in the incorrect place. The CA certificate must be loaded in the Trusted Root Certification Authorities tab in Certificates in Internet Explorer and the Authorities tab in the
Certificates Manager in Firefox.
To download the CA certificate, log on to the LMI and go to Manage System Settings > Network Settings > Outbound SSL Certificates. Select the Active Device
CA certificate and select Download.

The Security Network Protection (XGS) has removed root access for appliance security. In place of root access, IBM has developed a predefined set of the module commands to allow console and SSH CLI access. The modules available are broken up into a hierarchical structure with commands specific to each module. The prompt changes to display the module you are in and displays a list of the available commands.
Notes:
At any point, type help to display a list of the available commands.
The tab key can be used to finish commands (if you wanted to enter support, you can type su then tab key to complete support).

The requirements are as follows:
-> Avoid having to push certificates to all workstations
-> Protect users from fraudulent web sites
-> Protect all internal server from malicious attacks
The steps to implement this plan are as follows:
Obtain an SSL Inspection license for the XGS
-> Obtain a certificate from a public CA and upload it to the XGS via Outbound SSL Certificates
-> Obtain the certificate and private key of the internal public-facing web server and upload it to the XGS via Inbound SSL Certificates
-> Configure Outbound SSL Inspection Settings to block connections if the server certificate is invalid or self-signed
-> Create Outbound SSL Inspection rules that inspect all traffic
-> Create Inbound SSL Inspection rules that only decrypt traffic destined for the internal web server IP address
After implementing the plan, the System Administrator finds that users are blocked when trying to access the private company intranet site.
What should the System Administrator do to allow the users to access the intranet?
- A. Add intranet CA certificates to trusted Certificate Authorities.
- B. Add intranet CA certificates to the Inbound SSL Certificates store.
- C. Add an inbound SSL Inspection rule to ignore the traffic to the intranet site.

A System Administrator want to configure an XGS so that only when the SQL_Injection security event is enabled in the IPS policy and triggered, the XGS performs a packet capture of the complete connection from the point of the event triggering.
How should the System Administrator configure the XGS?
- A. Edit the SQL_Injection security event within the IPS policy and apply a response to capture the connection.
- B. Edit the IPS object that contains the SQL_Injection security event and apply a response to capture the connection.
- C. Create a Network Access policy object with a capture connection response object for the SQL_Injection security event.
- D. Create an IPS Filter Policy object for the SQL_Injection security event and apply a response to capture the connection.
Answer : D
You can configure the IPS Event Filter policy to tune the Threat (Severity) Level and responses for a specific Intrusion Prevention Policy rule (security events/ signature).
Incorrect Answers:
C: IPS event filters offer you the ability to change settings for a single or for a group of security events without having to create new Network Access policies or
Intrusion Prevention policies. The IPS Event Filter policy is similar to the Network Access Policy in that it is a single entity that you add rules to.
