Optimize Firewall Security - McAfee SecurityCenter version 10.5

The instructions given below are for McAfee SecurityCenter - Special edition from AOL version 10.5.

There are many ways the security of your computer can be compromised. For example, some programs can attempt to connect to the internet before Windows starts. In addition, sophisticated computer users can ping your computer to determine whether or not it is connected to a network. Firewall allows you to defend against both types of intrusion by allowing you to Enable boot time protection and to block ICMP ping requests. The first setting blocks programs from accessing the internet as Windows starts and the second blocks ping requests that help other users detect your computer on a network.

Standard installation settings include automatic detection for the most common intrusion attempts, such as Denial of Service attacks or exploits. Using the standard installation settings ensures that you are protected against these attacks and scans; however, you can disable automatic detection for one or more attacks or scans on the Intrusion Detection pane.

Protect your computer during startup

Firewall can protect your computer as Windows starts up. Boot time protection blocks all new programs that have not been previously granted and require access to the internet. After Firewall is launched, it displays relevant alerts for programs that had requested internet access during startup, which you can grant or block. To use this option, your security level must not be set to Open or Lockdown.

To protect your computer during startup:

1. In the Windows taskbar, next to the clock, right-click the M icon, and then click Open McAfee SecurityCenter.

Note: Alternatively, you can click Start, select All Programs, select McAfee, and then click McAfee SecurityCenter.

Tip: If you're using Windows 7 and don't see the McAfee icon next to the clock, click the arrow next to the clock to reveal hidden icons. At any time, you can customize your Windows 7 System Tray.

2. In the McAfee SecurityCenter window, click Firewall: On link.

3. On the right side of the McAfee SecurityCenter window, click Settings.

4. Click Smart Advice and Advanced Settings.

5. Select Enable protection during startup, and click Apply.

Configure ping request settings

Computer users can use a ping tool, which sends and receives ICMP Echo Request messages, to determine whether a given computer is connected to the network. You can configure Firewall to prevent or allow computer users to ping your computer.

To configure your ICMP ping requests setting:

1. In the Windows taskbar, next to the clock, right-click the M icon, and then click Open McAfee SecurityCenter.

Note: Alternatively, you can click Start, select All Programs, select McAfee, and then click McAfee SecurityCenter.

Tip: If you're using Windows 7 and don't see the McAfee icon next to the clock, click the arrow next to the clock to reveal hidden icons. At any time, you can customize your Windows 7 System Tray.

2. In the McAfee SecurityCenter window, click Firewall: On link.

3. On the right side of the McAfee SecurityCenter window, click Settings.

4. Click Smart Advice and Advanced Settings.

5. Select Allow ICMP ping requests, and click Apply.

Configure intrusion detection

Intrusion detection (IDS) monitors data packets for suspicious data transfers or transfer methods. IDS analyzes traffic and data packets for specific traffic patterns used by attackers. For example, when Firewall detects ICMP packets, it analyzes these for suspicious traffic patterns by comparing the ICMP traffic against known attack patterns. Firewall compares packets to a signature database and, if suspicious or harmful, drops the packets from the offending computer, and then optionally logs the event.

Standard installation settings include automatic detection for the most common intrusion attempts, such as Denial of Service attacks or exploits. Using the standard installation settings ensures that you are protected against these attacks and scans; however, you can disable automatic detection for one or more attacks or scans on the Intrusion Detection pane.

To configure intrusion detection:

1. In the Windows taskbar, next to the clock, right-click the M icon, and then click Open McAfee SecurityCenter.

Note: Alternatively, you can click Start, select All Programs, select McAfee, and then click McAfee SecurityCenter.

Tip: If you're using Windows 7 and don't see the McAfee icon next to the clock, click the arrow next to the clock to reveal hidden icons. At any time, you can customize your Windows 7 System Tray.

2. In the McAfee SecurityCenter window, click Firewall: On link.

3. On the right side of the McAfee SecurityCenter window, click Settings.

4. Click Firewall History.

5. Select Intrusion detection (IDS), and click Apply.
