hundreds of nodes, the efficiency would be too bad. In fact, in practical applications, it is not like this to manually build a complex tree. We should alreadyStore the node content and logical relationships of the entire tree in the database table.More importantly, this input should not be done by our developers. Because each node record in the table stores some of its own information, including whether it is a leaf or a parent node, what developers need is to make the programReads records fro
4. Transparency
The transparency of the firewall means that the firewall is transparent to the user, when the firewall is connected to the network, the network and the user do not need to do any setup and the change, also do not realize the firewall existence at all.
Firewall as a physical device, if you want to put into the existing network without any impact on the network, you must be in the way of Network Bridge. In the traditional way, firewall

I won't say much about how to connect to the computer. It is everywhere on the Internet. But it seems to be worth noting that, first power up the firewall after the Super Terminal is opened, otherwise nothing can be seen on the Super Terminal.

Because the pre-installed IOS version of the PIX series firewall is 6.x and only version 7.0 or above supports transparent mode, the

In general, the two network interfaces of a firewall should belong to two different networks, forwarding packets between two interfaces according to the access rules defined by the system administrator, or rejecting or discarding packets. In fact, firewalls are not just a function of access control, but they also act as the role of routers.
