MC78L15ACDR2 Article About

The example above for the personal use of the exchange of visits between the two computers problem, did not consider too much security and other factors. In the business sector such as the use of VPN between the programs, the VPN network is built on open Internet platform, the virtual network, it must ensure that no authorized user can not access VPN network; generally use a dedicated VPN server installation, This enterprise network personnel through it, you can specify that only meet the specific requirements of the users can connect as VPN server to gain access, and can encrypt data on all VPN to ensure data security.
Most popular router is in the form of hardware, but in some cases, applications to achieve "software router", the only difference between the two is the efficiency of execution is different. General at least two network routers linked and connected to the network based on its decision to the state of the transmission path of each packet. Router to generate and maintain a known as the "routing information sheet" form, which keep track of neighboring routers address and other status information. Routers use routing information table and in accordance with the transmission distance and communication costs optimization algorithm to determine a specific data packet best path. It is this characteristic determines the routers "intelligence", which according to actual running status of the adjacent network automatically select and adjust the transmission of data packets the situation and make the greatest efforts to the best routes and the cost of the smallest packet passed out. Security and stability of the router can run a direct impact on Internet activities. Whatever the reason there is a router crashes, denial of service or a sharp decline in operating efficiency, the result would be catastrophic. Means of hacking routers and other computer attacks on the Internet much the same way, in the strict sense because the router itself is a computer with a special mission, although it may not be familiar with the PC, as people usually look. In general, the hacker attacks against the router can be divided into two types: first, by some means or means to obtain administrative privileges, direct invasion to the systems internal; One way to use a remote attacker cause a router crash or run crash efficiency decreased significantly. In comparison, the difficulty of the former is larger.
