Introduction

Antivirus forms an important part of any organisations’ network and hence monitoring your Antivirus is imperative. Symantec Antivirus sends malware related information in the form of logs over syslog protocol. 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. Installing the KHIKA App for Symantec Antivirus
  3. Get data from your Symantec Antivirus into KHIKA Aggregator

Enabling Syslog forwarding on the device

Please refer below steps for enabling syslogs on your Symantec Antivirus Server.

The procedure to enable for external logging is as mentioned below:
1. In the Symantec Endpoint Protection Management console, click Admin.
2. Click Servers.
3. Click the local site or remote site that you want to export log data from.
4. Click Configure External Logging.
5. On the General tab, in the Update Frequency list box, select how often to send the log data to the file. (You can say 30 seconds here)
6. In the Master Logging Server list box, select the management server to send the logs to.
7. Use SQL Server and connect multiple management servers to the database, specify only one server as the Master Logging Server.
8. Check Enable Transmission of Logs to a SYSLOG Server.
9. Provide the following information: (NOTE: Firewall port 514 must be opened for syslog server to receive the messages) SYSLOG Server – Specify the IP address or domain name of the KHIKA Virtual Appliance that embeds SYSLOG server that will receive the log data. Destination Port & Protocol - Specify the protocol as ‘UDP’ and port as ‘514’ Log Facility – Specify the log facility as - 4
10. On the Log Filter tab, check which logs to export. (Select ALL the possible logs here)
11. Click OK.
Admin-> Servers-> Local Site -> Configure External Logging

Verifying SYSLOG data collection

After you enable the syslog forwarding on the end device, you must verify if the logs are being really received by KHIKA Data Aggregator. Please refer here to understand how to verify syslogs on KHIKA Data Aggregator.

How to Install the KHIKA App for Symantec Antivirus ?

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 Symantec Antivirus - Symantec Antivirus. Installing the application shall put together and activate the adapter (parser) that can handle Symantec Antivirus data format, the dashboards and the alert rules preconfigured.

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

Symantec Antivirus Alerts

Alerts are generated when certain critical behavior is observed in the system. Alerts can be monitored in real-time on Alerts Dashboard in KHIKA. Relevant stakeholders can also receive the alerts via emails. The table below explains all the pre-canned alerts shipped with KHIKA App for Symantec Antivirus.

Alerts Description

Alert Details Table
Alert Name Description Suggested Resolution
Host with multiple infections This alert is triggered when host is infected with multiple(two or more) viruses within a 5 minutes of interval. A host infected with multiple viruses is a good indication of a compromised host and this becomes a weak link in the network and can be used by the attacker to launch sophisticated attacks.

Quarantine the host. Understand the behavior of the host by checking recent history (such as websites visits from proxy or firewall logs, email download, USB events if any). Check hosts showing similar threats. Try to correlate the behavior.

Antivirus audit policy changed This alert is triggered when someone modifies the system audit policy. Someone modified system audit policy.

Check with admin. Check if CR was in place.

Virus Infection Detected This alert is triggered when system Symantec detects virus on the system. System is affected with virus. It is normal as long as the Symantec AV is cleaning the virus.

No immediate action is needed. However, if the same system is getting affected with virus/viruses multiple times, the system should be deeply inspected for
1) Network traffic to websites (firewall)
2) Emails
3) USB events if any

Single virus outbreak on few hosts This is alert is triggered when malware is found on multiple hosts but not cleaned. This is a typical case of a virus spreading laterally.

Quarantine the affected hosts. Clean the virus. Check threat intelligence (VirusTotal etc.) for virus source. Check with your AV experts

Malware detected but not cleaned This alert is triggered when malware is detected on a host but not cleaned within 24 hours of time window. An uncleaned malware is dangerous. The machine remains in compromised state and it could be a potential danger to the entire network.

Clean the malware manually. Check the reason why was it not cleaned.

Antivirus audit policy added Alert triggered when someone modifies the system audit policy,typically added new policy. Someone modified system audit policy.

Check with admin. Check if CR was in place.

variety of viruses on multiple hosts This alert is triggered when multiple viruses are detected on multiple hosts but not cleaned. Multiple host have been infected with different viruses within a short time span. This is a typical case of virus outbreak showing multiple varieties.

To treat the symptom, quarantine the affected hosts. Clean the virus. Check threat intel (VirusTotal etc.). It may happen that the hosts are infected with similar type viruses, with different names. This could be lateral spread of the virus. Consult virus experts to now more about the type of the virus

single virus outbreak on multiple hosts This alert is triggered when typical case of virus outbreak is detected that shows multiple hosts are detected with multiple of same virus within short time span. Multiple host have been infected with same or different viruses within a short time span. This is a typical case of virus outbreak.

To treat the symptom, quarantine the affected hosts Clean the virus. Check threat intel (VirusTotal etc.). It may happen that the hosts are infected with similar viruses, with different names. This could be lateral spread of the virus. Consult virus experts to know more about the type of the virus

Multiple malware detected but not cleaned This alert is triggered when uncleaned malware is detected on a host. An uncleaned malware is dangerous. The machine remains in compromised state and it could be a potential danger to the entire network.

Clean the malware manually. Check the reason why was it not cleaned. It is also important to investigate why multiple infections were seen on a single host
