Firewalls-tiered protection The typical demilitarized zone (DMZ) has two firewalls. The external firewall is configured to allow only the communication required to connect between the Internet and the DMZ. The internal firewall is configured to protect the internal network

Understanding of the PIX FirewallThe pix is a Cisco hardware firewall, which features fast operation and convenient use.There are many models of the PIX, and the number of concurrent connections is an important parameter of the PIX Firewall. Pix25 is a typical device.Common interfaces of the PIX Firewall include console, failover, Ethernet, and USB.Network region:Internal Network: InsideExternal Network: OutsideIntermediate region: DMZ (ceasefire z

3. Use ACLIn the following network, use the ACL named acl_out On The inside interface to control inbound traffic. This ACL rejects HTTP connections from the internal network, and allows all other IP addresses to pass through. Using this ACL on the inside interface allows internal users to establish external connections. To allow outbound connections, the internal network address (10.0.0.0) is dynamically converted from 192.168.0.20 to 192.168.0.254.The following lists the ACL configurations for

, warning and auditing, intrusion detection, and other aspects. For example, CBAC uses the timeout value and threshold value to determine the session Status and duration. It can clear incomplete sessions and idle sessions for Dos detection and protection. However, the disadvantage of CBAC is that it performs the same review policies on all traffic passing through the interface and cannot precisely control the firewall policies, which is relatively difficult to deploy.To address this problem, a n

information about operations and services that should be performed, and perceiving whether other devices exist and their functions and current status, each device can read its own specific status and parameters. The Protocol is a framework system composed of multiple layers of protocols. Each layer is based on an adjacent lower layer and the foundation of the adjacent upper layer until the application layer is reached. DMZ

Network path analysis tools and power-assisted firewall management and fault repair is very important. Although network path analysis tools such as route tracking are effective at examining the impact of individual network devices on network packet transmission, they cannot help engineers understand the role of network security devices. Athena Security Company's new Pathfinder Network path Analysis product provides such secure infrastructure visibility. Network engineers can upload configurati

Stateful detection firewall: Do not check the data area, establish the connection state table, the front and back message correlation, the application layer control is very weak. Compound firewall: It can check the whole packet content, establish the connection state table according to the need, the network layer protection is strong, the application layer control is fine, the session control is weak. 4, Firewall terminology Gateway: A system that provides forwarding

The ER series routers are available in three modes: NAT mode, route mode, and full mode. The differences and applications of the three modes are as follows:NATModeIn NAT mode, when the DMZ port is in Wan mode or LAN mode, the mode relationships between interfaces are also different.1DMZ port is in Lan modeThe LAN and WAN are in NAT mode, and the DMZ and WAN are also in NAT mode. That is, the IP address of t
