Trend Micro OfficeScan 10 Service Pack 1 Administrator’s Guide 7-18 To view firewall logs: PATH: LOGS > NETWORKED COMPUTER LOGS > SECURITY RISKS > VIEW LOGS > FIREWALL LOGS NETWORKED COMPUTERS > CLIENT MANAGEMENT > LOGS > FIREWALL LOGS 1. To ensure that the most up-to-date logs are available to you, click Notify Clients. Allow some time for clients to send firewall logs before proceeding to the next step. 2. Specify log criteria and click Display Logs. 3. View logs. Logs contain the following information: • Date and time of firewall violation detection • Computer where firewall violation occurred • Remote host IP address • Local host IP address • Protocol • Port number • Description: Specifies the actual security risk (such as a network virus or IDS attack) or the firewall policy violation • Direction: If inbound (Receive) or outbound (Send) traffic violated a firewall policy • Process: The executable program or service running on the computer that caused the firewall violation 4. To save the log to a comma-separated value (CSV) file, click Export to CSV. Open the file or save it to a specific location. A CSV file usually opens with a spreadsheet application such as Microsoft Excel. Testing the OfficeScan Firewall To help ensure that the OfficeScan firewall works properly, perform a test on a client or group of clients.
Using the OfficeScan Firewall WARNING! Test OfficeScan client program settings in a controlled environment only. Do not perform tests on client computers connected to the network or to the Internet. Doing so may expose client computers to viruses, hacker attacks, and other risks. To test the firewall: 1. Create and save a test policy. Configure the settings to block the types of traffic you want to test. For example, to prevent the client from accessing the Internet, do the following: a. Set the security level to Low (allow all inbound/outbound traffic). b. Select Enable firewall and Notify users when a firewall violation occurs. c. Create an exception that blocks HTTP (or HTTPS) traffic. 2. Create and save a test profile, selecting the clients to which you will test firewall features. Associate the test policy with the test profile. 3. Click Assign Profile to Clients. 4. Verify the deployment. a. Click Networked Computers > Client Management. b. Select the domain to which a client belongs. c. Select Firewall view from the client tree view. d. Check if there is a green check mark under the Firewall column of the client tree. If you enabled the Intrusion Detection System for that client, check that a green check mark also exists in the IDS column. e. Verify if the client applies the correct firewall policy. The policy appears under the Firewall Policy column in the client tree. 5. Test the firewall on the client computer by attempting to send or receive the type of traffic you configured in the policy. 6. To test a policy configured to prevent the client from accessing the Internet, open a Web browser on the client computer. If you configured OfficeScan to display a notification message for firewall violations, the message displays on the client computer when an outbound traffic violation occurs. 7-19
