Vista system firewall settings

First, use two interfaces to meet different needs

Vista Firewall has two independent graphical configuration interfaces: First, the basic configuration interface can be passed through "Security Center" and “ Control Panel & rdquo; to access; Second, the advanced configuration interface, the user can be accessed as a plug-in after creating a custom MMC.

This prevents unintentional changes for novice users from causing connection disruptions, and provides a way for advanced users to fine-tune firewall settings and control outbound and inbound traffic. Users can also use the command in the netsh advfirewall context to configure the Vista firewall from the command line. Scripts can also be used to automatically configure the firewall for a group of computers. Group Policy can also be used to control the settings of the Vista firewall.

Second, security under default settings

Windows Firewall in Vista uses security configuration by default, while still supporting the best ease of use. By default, most inbound traffic is blocked and outbound connections are allowed. The Vista firewall works in conjunction with Vista's new Windows Service Hardening feature, so if the firewall detects behavior that is prohibited by Windows Service Hardening Network Rules, it blocks this behavior. The firewall also fully supports a pure IPv6 network environment.

Third, basic configuration options

With the basic configuration interface, users can start or close the firewall, or set the firewall to completely block all programs; can also allow exceptions exist (can specify which do not block which Program, service, or port), and specify the scope of each exception (whether it applies to traffic from all computers, including computers on the Internet, computers on the LAN/subnet, or computers to which you specify an IP address or subnet) ); You can also specify which connections you want the firewall to protect and configure security logs and ICMP settings.

IV. ICMP Message Blocking

By default, inbound ICMP echo requests can pass through the firewall, while all other ICMP messages are blocked. This is because the Ping tool is periodically used to send an echo request message for troubleshooting. However, the hacker can also send an echo request message to lock the target host. The user can block the response request message through the “Advanced” tab on the basic configuration interface.

V. Multiple Firewall Configuration Files

The Vista Firewall with Advanced Security MMC plug-in allows users to create multiple firewall profiles on their computers so that different firewalls can be used for different environments. Configuration. This is especially useful for portable computers. For example, when a user connects to a public wireless hotspot, it may require a more secure configuration than when connected to a home network. Users can create up to three firewall profiles: one for connecting to a Windows domain, one for connecting to a private network, and one for connecting to a public network. 6. IPSec function

Through the advanced configuration interface, users You can customize the IPSec settings, specify security methods for encryption and integrity, determine whether the key's lifetime is calculated on a per-session basis, and select the desired Diffie-Hellman key exchange algorithm. By default, the data encryption feature of an IPSec connection is disabled, but it can be enabled and which algorithms are selected for data encryption and integrity.

VII. Security Rules

Through the wizard, users can gradually create security rules to control how and when a secure connection is established between a single computer or a group of computers. Standards such as members or security conditions restrict connections, but allow specified computers to fail to meet connection verification requirements; rules can also be created to require authentication for two specific computers (server-to-server) connections, or tunnel rules for gateways The connection between them is verified.

VIII. Customized Validation Rules

When creating a custom validation rule, specify a single computer or a group of computers (by IP address or address range) to become the connection endpoint. The user can request or request verification of an inbound connection, an outbound connection, or both.

IX. Inbound and Outbound Rules

Users can create inbound and outbound rules to block or allow specific programs or ports to connect; they can use pre-set rules or Create a custom rule, “New Rule Wizard” can help users step through the steps of creating a rule; users can apply the rule to a set of programs, ports or services, or apply the rule to all programs or a specific program; You can block a software from making all connections, allow all connections, or allow only secure connections, and require encryption to secure the data sent over the connection; you can configure source IP addresses and destinations for inbound and outbound traffic IP addresses can also be configured for source TCP and UDP ports as well as destination TCP and UPD ports.

X. Active Directory-Based Rules

Users can create rules to block or allow connections based on Active Directory user, computer or group accounts, as long as the connection is through Kerberos v5 (with Active Directory) Account information) IPSec to protect security. Users can also use the Windows Firewall with advanced security features to enforce Network Access Protection (NAP) policies.
