Introduction

Most of the network devices, such as firewalls, switches, routers, web proxies etc send the traffic and user activity related information in the form of logs over syslog protocol. Some applications such as Oracle database server, Symantec antivirus server, EMC SAN Storage etc also support syslog protocol as syslog is very efficient and simple to integrate with. KHIKA Data Aggregator is pre-configured with syslog services on port 514. The key parts to get here are :

  1. Enabling Syslog forwarding on the device
  2. Install the KHIKA App for PaloAlto Firewall
  3. Get data from your PaloAlto Firewall into KHIKA Aggregator

Enabling Syslog forwarding on the device

you are recommended to refer to Paloalto documentation for enabling syslogs on your firewall device.

You can refer below suggested steps for enabling syslogs on your PaloAlto firewall device.

1.Configure a Syslog server profile

  1.Select Device > Server Profiles > Syslog.
  2.Click Add and enter a Name for the profile.
  3.If the firewall has more than one virtual system (vsys), select the Location (vsys or Shared) where this profile is available.
  4.For each syslog server, click Add and enter the information that the firewall requires to connect to it:
    Name — Unique name for the server profile.
    Syslog Server — IP address or fully qualified domain name (FQDN) of the syslog server.
    Transport — Select TCP, UDP, or SSL as the method of communication with the syslog server.
    Port —The port number on which to send syslog messages (default is UDP on port 514); you must use the same port number on the firewall and the syslog 
    server.
    Format —Select the syslog message format to use: BSD (the default) or IETF. Traditionally, BSD format is over UDP and IETF format is over TCP or SSL.
    Facility —Select a syslog standard value (default is LOG_USER) to calculate the priority (PRI) field in your syslog server implementation. Select the 
    value that maps to how you use the PRI field to manage your syslog messages.
  5.Click OK to save the server profile.

2.Configure syslog forwarding for Traffic, Threat, and WildFire Submission logs.

  1.Create a log forwarding profile.
    For creating log forwarding profile please refer this log forwarding profile
    Select Objects > Log Forwarding, click Add, and enter a Name to identify the profile.
    For each log type and each severity level or WildFire verdict, select the Syslog server profile and click OK.
  2.Assign the log forwarding profile to security rules.
    For creating log forwarding profile to security rules please refer this log forwarding profile to security rules

3. Configure syslog forwarding for System, Config, HIP Match, and Correlation logs.

  Select Device > Log Settings.
  For System and Correlation logs, click each Severity level, select the Syslog server profile, and click OK.

` For Config, HIP Match, and Correlation logs, edit the section, select the Syslog server profile, and click OK.

4. Commit your changes and review the logs on the syslog server.

  Click Commit.
  To review the logs, refer to the documentation of your syslog management software.

How to Install the KHIKA App for PaloAlto Firewall?

It is assumed, that you have already configured KHIKA Data Aggregator in your environment. If not, please read how to configure KHIKA Data Aggregator and perform the pre-requisite steps.

This section explains how to pick and install the KHIKA application for PaloAlto Firewall . Installing the application shall put together and activate the adapter (parser) that can handle PaloAlto Firewall data format, the dashboards and the alert rules preconfigured.

Go to “Applications” tab in the “Configure” menu.

Paloalto application tab11.jpg

Check whether the appropriate Workspace is selected. Note: Application is always loaded in a Workspace. Read the section on Workspaces to know more about KHIKA Workspaces. Also select your KHIKA aggregator name in the Node dropdown. This is to ensure that we are collecting data from the desired source and into the correct workspace which is ready with the configured application and components.

Paloalto application.jpg

Click on the “+” button. A pop up appears.

User can now select the contents of the application required. For example, on the dropdown for “Reports”, click to expand it. List of all reports can be seen. User can individually select the reports required by checking on the checkbox next to each. Alternatively, check on “Select All” option to get all of them. Similarly you can select contents from Alerts and Dashboards.

What are KHIKA Reports
What are KHIKA Dashboards
What are KHIKA Alerts

Click “OK” to proceed with the installation of the selected Application. After successful installation, following status should be displayed :

Paloalto application status.jpg

This simple procedure to install a KHIKA App, automatically configures the Adapter (required for parsing the data from raw syslogs), calculated KHIKA reports on raw data, Visualizations, Dashboards and Alerts – all in one click.

Adding the device in the Adaptor

After syslogs are enabled on the device and the App is installed into KHIKA, it is the time to add the device to the this App (in Adapter section of KHIKA Web GUI). Please refer here to know how to add the device to an App.

After making these configuration changes in KHIKA, you must apply these changes to the Workspace. Go to Configure, select the Workspace and in Workspace tab of configure menu press the Apply button as shown in the screenshot below.

PaloAlto Firewall Alerts

Alerts are generated when certain ciritical behaviour is observed in the system – real time and notified on the Alerts Dashboard in KHIKA as well as can be received in email to relevant stakeholders. The details of KHIKA Alerts are mentioned here Click on “Alert Dashboard” on left menu.

Certain alerts for paloalto firewall are pre-canned and shipped with KHIKA, keeping in mind the requirements of the users. They are mentioned in the table below :

Alerts Description

Alert Details Table
Alert Name Description Suggested Resolution
Paloalto firewall communication with suspicious ip This alert is triggered when bytes are send and receive during communication with Maliacious IP. Communication with a bad IP is happening, it must be blocked immediately as it could be a possible attack or data exfiltration.

You can check the log for this communication by simply searching the malicious IP in the logs. You can also check which internal IP addresses are communicating with this IP address and track the real users behind those internal IP addresses.

If you see an internal IP constantly getting involved in malicious communication (with same or multiple external IP addresses), you may install agents on the internal nodes involved and check the real user and process responsible for this communication.

If required, quarantine the affected internal servers till the time the issues are resolved.
Paloalto firewall host scan activity by malicious ip This alert is triggered when more than 10 connections happened from same malicious IP using different destination port, within one minute Bad ip address tries to spray connection requests on multiple popular ports (21,22,53,80,443 etc) targetting one single IP address at a time with an intention to find the open ports on the target IP address. Typically, scan attempt is the first stage of reconnaissance in the attack life cycle.

It is important to check the reputation of the external ip address and block the same if necessary.
Paloalto firewall successful host scan activity by malicious ip This alert is triggered when more than 10 connections happened from same malicious IP and status is deny followed by a successful login status using different destination port, within one minute. Bad ip address tries to spray connection requests on multiple popular ports (21,22,53,80,443 etc) targetting one single IP addresses at a time with an intention to find the open ports on the target IP address. Typically, scan attempt is the first stage of reconnaissance in the attack life cycle and attacker done successful connection on open ports.

It is important to check the reputation of the external ip address and block the same if necessary.

It is also important to verify the sanity of affected internal nodes by checking if any unwarranted system policy change or software configuration/updates have occured during the affected time period. If required, quarantine the affected servers till the time the issues are resolved.
Paloalto firewall successful host scan activity This alert is triggered when more than 10 connections happened from same Source and Destination IP and status is deny followed by successful login status using different destination port, within one minute. Attacker tries to spray connection requests on multiple popular ports (21,22,53,80,443 etc) targetting one single IP addresses at a time with an intention to find the open ports on the target IP address. Typically, scan attempt is the first stage of reconnaissance in the attack life cycle and attacker done successful connection on open ports.

It is important to check the reputation of the suspected ip address.

If the suspected ip address is external, you may consider blocking it.

If the suspected ip address is internal, you may need to verify the sanity of the corresponding device.

It is also important to verify the sanity of affected internal nodes by checking if any unwarranted system policy change or software configuration/updates have occured during the affected time period. If required, quarantine the affected servers till the time the issues are resolved.

This may be a false positve.
Paloalto firewall sweep scan attack by malicious ip This alert is triggered when more than 10 connections happened from same malicious IP using different Destination IP's, within one minute. Bad ip addresses tries to spray connection requests on one of the popular ports (21,22,53,80,443 etc) on multiple IP addresses with an intention to find which ports are opened on what IP addresses. Typically, scan attempt is the first stage of reconnaissance in the attack life cycle.

It is important to check the reputation of the external ip address and block the same if necessary.

Paloalto firewall worm detected This alert is triggered when destination ports are('445','137','138','139') and "untrust-l3" value is available in traffic type of events. Log messages indicative of a worm are detected. Check the attacking IPs in question. Verify the reputation these IPs in reputation databased such as virustotal.com, ipvoid.com etc.
Paloalto firewall backdoor activity detected This alert is triggered when connection happened using vulnerable Destination ports like 3127,3198,6129,7080,within one minute. This event indicates that a traffic is generated from internal machine on vulnerable ports(3127,3198,6129,7080). Typically, these ports are used by attacker to exploit vulnerable programs listening on these ports.

Check is these ports are open and on what servers. Do you really need these ports opened?

Check what programs are running on these ports. Check vulnerability reports of the applications\nBlock these ports for external traffic, unless mandatory to keep them opened.

If you have to keep any of these ports opened, try to restrict the access to legitimte IPs.

If you get a suspicious IP repetatively trying to access these port, block the IP. Check the reputation of the IP on popular website such as ipvoid.com, virustotal.com etc.
Paloalto firewall host scan attack This alert is triggered when more than 10 connections happened from same Source and Destination IP using different destination port, within one minute. An attacker tries to spray connection requests on multiple popular ports (21,22,53,80,443 etc) targetting one single IP addresses at a time with an intention to find the open ports on the target IP address. Typically, scan attempt is the first stage of reconnaissance in the attack life cycle.

Unless it is a known and legitimate IP address performing the scan, it is important to block this IP. You may whitelist the known IP addresses (such as designated Vulnerability Scanner, Asset Discovery Tools etc), so as to supress the false positives.
Paloalto firewall communication with possible IOC or bad IP This alert is triggered when suspicious IP is communicate with internal IP. KHIKA shares community based threat intelligence (TI) every 24 hours. TI has list of IP addresses with bad reputation. Every bad IP is marked with number of communities reporting it, name of each community and confidence indicating how confident are we about the reputation. This alert is generated when communication with a bad IP is let through.

If communication with a bad IP is happening, it must be blocked immediately as it could be a possible attack or data exfiltration.

You can check how log this communication is happening by simply searching the malicious IP in the logs. You can also check what internal IP addresses are communicating with this IP addresses and track the real users behind those internal IP addresses.

Cross-check the reputation of the IP with popular websites such as ipvoid.com, virustotal.com.

If you see an internal IP constantly getting involved in malicious communication (with same or multiple external IP addresses), you may install agents on the internal nodes involved and check the real user and process responsible for this communication.

It is critical to block this rogue communication.
Paloalto firewall sweep scan attack This alert is triggered when more than 10 connections happened from same source IP to various Destination IP's,within one minute. An attacker tries to spray connection requests on one of the popular ports (21,22,53,80,443 etc) on multiple IP addresses with an intention to find which ports are opened on what IP addresses. Typically, scan attempt is the first stage of reconnaissance in the attack life cycle.

It is critical to block this rogue communication.
Paloalto firewall high ICMP request from single host This alert is triggered when 10 events of ICMP protocol is used by same source occured within 1 min ICMP probe is an old and established technique used by attackers as the first step that involves reconnaissance. This is used to check what IPs/Hosts are responding to the ping request so that further targeted can be launched on the responding IPs/Hots.

The probing IP, if not a legitimate IP, ,it should be blocked at the periphery.

Check the reputation of the probing IP in external reputation databases, such as VirtusTotal.com or IPVoid.com etc. If the reputation is found to be dubious or bad, you must block such IPs.
