KHIKA App for Checkpoint Firewall

Introduction

Firewall form an important part of organisations’ networks and hence by monitoring your firewall is imperative. Checkpoint Firewall send the traffic and user activity related information in the form of logs over syslog protocol. 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 Checkpoint Firewall
3. Get data from your Checkpoint Firewall into KHIKA Aggregator

How to Install the KHIKA App for Checkpoint 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 Checkpoint Firewall - Checkpoint Firewall. Installing the application shall put together and activate the adapter (parser) that can handle Checkpoint Firewall data format, the dashboards and the alert rules preconfigured.

How to load an App

How to get your Checkpoint Firewall into KHIKA ?

KHIKA recommends, popular syslog forwarding to monitor the Checkpoint Firewall. You must configure the network device (or the end node) to send its logs to KHIKA Data Aggregator by providing IP address of Data Aggregator and port 514 so that the device can send its logs to KHIKA syslog service. (Please refer the documentation of individual device/vendor/OEM to understand how to configure remote syslogging for the device. Many vendors support web based configuration these days and some vendors support command based configurations)

Pointer:- You may refer to link [[1]] explaining syslog forwarding in checkpoint firewall.
Note:- We recommend referring to OEM manual for enabling syslogs on your version of checkpoint firewall

NOTE: You will have to repeat these steps on each of the Checkpoint Firewall that you wish to monitor using KHIKA.

Chekpoint Firewall Alerts

Alerts are generated when certain critical behavior 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 Checkpoint 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
Checkpoint firewall Possible data exfiltration	This alert is triggered when large amount of data (more than 5 MB ) being sent to an external network.	This alert is detected when a large amount of data is uploaded on external sites. This may be an attempt of data ex-filtration from the organisation. Please check the real user associated with the source IP and the workstation from which the data upload happened. Verify if sensitive data was ex-filtrated.
Checkpoint firewall Checkpoint control log message	This alert is triggered when action is ctl and internal message is generated by Checkpoint	Checkpoint internal message is generated. Please check the documentation of Checkpoint and do the suggested action.
Checkpoint firewall Possible icmp probe	This alert is triggered when high inbound icmp requests are made and are accepted	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.
Checkpoint firewall IPS bypassing	This alert is triggered when IPS is bypassed.	The firewall IPS mode is enabled by default in NextGen firewalls. However, sometimes the firewall runs out of its resources, such as CPU or Memory due sudden heavy load. In such cases, the firewall disables the IPS mode so that it can service the traffic traffic. Disabled IPS mode on the peripheral firewall is a compromised operating mode as an attacker can invade into your network by exploiting the lack of IPS service on your firewall.
Checkpoint firewall Worm detected	This alert is triggered when traffic is generated on port 445,137,138,139 and communication direction is inbound	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.
Checkpoint firewall Backdoor activity detected	This alert is triggered when traffic is generated from internal machine on vulnerable ports(3127,3198,6129,7080).	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 Block 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 legitimate IPs. If you get a suspicious IP repetitively trying to access these port, block the IP. Check the reputation of the IP on popular website such as ipvoid.com, virustotal.com etc.
Checkpoint firewall Communication with possible IOC or bad IP	This alert is triggered when any one of the Source or Destination IP is found malicious with accepted action	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 ex-filtration. 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.
Checkpoint firewall host scan activity by malicious ip	This alert is triggered when same malicious ip is trying to generate traffic for one destination ip on more than 10 different ports within 1 minute and the request is denied.	Bad ip address tries to spray connection requests on multiple popular ports (21,22,53,80,443 etc) targeting 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.
Checkpoint firewall successful host scan activity	This alert is triggered when same source ip is trying to generate traffic for one destination ip on more than 10 different ports but all the time request is denied .After that same source ip attempts to connect to same destination on one more port and this time it successfully connects on that port. All this happen within 1 minute.	Attacker tries to spray connection requests on multiple popular ports (21,22,53,80,443 etc) targeting 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 occurred during the affected time period. If required, quarantine the affected servers till the time the issues are resolved. This may be a false positive.

Bad ip address 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 and attacker finds open port on one of ip addresses and is able to establish a connection. 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 occurred during the affected time period. If required, quarantine the affected servers till the time the issues are resolved.
Checkpoint firewall communication with suspicious ip	This alert is triggered when bytes are sent and received during communication with malicious ip within 1 minute.	Communication with a bad IP is happening, it must be blocked immediately as it could be a possible attack or data ex-filtration. 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.
Checkpoint firewall large data sent outside	This alert is triggered when large amount of data (more than 1 GB) being sent to an external network	Large amount of data being sent to an external network could be an indication of data ex-filtration. Check with the user or process which is responsible for the data being sent out and whether it was done for legitimate business reasons. This could be a false positive.
