Set up your Vista operating system firewall method

First, the use of two interfaces to meet different needs Vista firewall has two independent graphical configuration interface: First, the basic configuration interface, you can access through the "security center" & rdquo; & & ldquo; control panel & rdquo;; It is an advanced configuration interface that users can access as a plug-in after creating a custom MMC. This prevents unintentional changes by 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, the security under the default settings Windows Firewall in Vista uses the 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, the basic configuration options The basic configuration interface, the user can start or close the firewall, or set the firewall to completely block all programs; can also allow exceptions exist (can specify which programs, services or ports are not blocked), and specify each exception The scope of the situation (whether applicable 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 the Advanced Security MMC plug-in allows users to create multiple firewall profiles on their computers so that different firewall configurations can be used for different environments. 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. IPSec function Through the advanced configuration interface, users can customize IPSec settings, specify security methods for encryption and integrity, determine whether the key life cycle is calculated by time or by session, and select the required 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. The connection can also be restricted according to domain members or security conditions, but allowed. The specified computer may not meet the connection verification requirements; you can also create rules that require authentication when two specific computers (server-to-server) are connected, or tunnel rules to verify the connection between the gateways. Customized Validation Rules When creating a custom validation rule, you specify that a single computer or a group of computers (through an IP address or range of addresses) becomes the connection endpoint. The user can request or request verification of an inbound connection, an outbound connection, or both. Inbound and Outbound Rules Users can create inbound and outbound rules to block or allow specific programs or ports to connect; you can use pre-set rules or create custom rules, “New Rule Wizard” You can step through the steps of creating rules; users can apply rules to a set of programs, ports, or services, or apply rules to all programs or a specific program; block a software from making all connections, allowing all connections , or only allow secure connections, and require encryption to protect the security of data sent over the connection; source and destination IP addresses can be configured for inbound and outbound traffic, as well as source TCP and UDP ports And destination TCP and UPD port configuration rules. X. Active Directory-Based Rules Users can create rules to block or allow connections based on Active Directory users, computers, or group accounts, as long as the connection is secured by IPSec with Kerberos v5 (containing Active Directory account information). Users can also use the Windows Firewall with advanced security features to enforce Network Access Protection (NAP) policies. Windows Meeting Space (WMS) is a new program built into Windows Vista that allows up to 10 collaborators to share desktops, files, and presentations, and send personal messages to each other over the network.
