(1) Cut off the default. First a step necessary to cut the default settings for the packet. ip address inside 192.168.1.1 255.255.255.0 10full —— set 10Mb/s Ethernet full duplex communication Physically using hardware as an encrypted circuit does not fundamentally resist this attack. Siemens uses encryption in the storage and uses a hardware encryption bus. However, the key actually used in encryption and decryption still appears in the CPU in the form of plain text , and the analyst can obtain the key using the DPA method. 3) Use encryption technology Table . 5 - 14 describes the conduit command parameters, it is shown in the following syntax. E-mail is transmitted at the speed of electronic streaming, which is very fast. The user ( sender ) sends it to a friend ( recipient ) in the United States in Shenzhen , and the other party can receive it in a few minutes. Especially suitable for data transmitted via the Internet. The security of the RSA algorithm is based on the difficulty of decomposing large numbers (in terms of computer processing power and processing time ) .

By overflowing a buffer,ccna certification material pdf, hackers can rewrite adjacent program spaces and skip system checks directly. The program space breakthrough of this type of program is different from the internal space positioning. The methods of controlling the transfer of the program to the attack code can be divided into the following types.
