Examples of combinations of different backup types
full backups and differential backups
Make a full backup in Monday, with differential backups from Tuesday to Friday. If the data is compromised in Friday, you only need to restore the Monday full backup and the
With the expansion of Linux enterprise applications, there are a large number of network servers using the Linux operating system. Linux server security can be more and more attention, here according to the depth of the attack on the Linux server in the Level form, and propose different solutions.

database from being found is to have a complex, unconventional name for an Access database file and store it in a multi-tiered directory. For example, for a database file on an online bookstore, do not simply name "Book.mdb" or "store.mdb", but rather an unconventional one, such as: Faq19jhsvzbal.mdb, and then put it in a./akkjj16t/kjhgb661/acd/ A deep directory like avccx55. In this way, some illegal access to the file name of an Access database can be effectively blocked by guessing.2. Using

The database system forms an encrypted string by "XOR" the password entered by the user with a fixed key and stor
Asp.net| Error | error handling ASP. NET has a good new feature: it provides rich support for handling and tracking run-time errors. In particular, it provides an easy way for managers to ensure that scary "ASP 43433ax" hexadecimal errors are never displayed to customers. Instead, it allows the display of a more customized message, such as "Sorry, this site is not available." Asp. NET also provides a powerful way for developers to equip their code to provide managers with additional information

At present, many wireless node devices introduced by the market default settings are allowed to broadcast the wireless network identifier, once the feature is enabled, the equivalent of wireless node devices automatically to the wireless coverage of all normal workstations to publish the local wireless network identifier name information. Although enabling the SSID identifier broadcast feature makes it easy to join a local wireless netwo
DESCryptoServiceProvider.
Most symmetric algorithms require two separate byte arrays for the encryption process. The first one is the key. For DES, the key is 8 bytes, while the other algorithms use a different number of bytes.
The private key must be passed to the person who decrypted the file in a secure manner, and the encrypted information will be compromised if the private key is compromised. But even

Organizations cannot tolerate attacks in the network spreading to all sensitive resources of the company. Businesses want to be able to quickly identify, control, and eliminate attacks to ensure that network resources are not compromised or compromised.

Let's take a look at how a perfect Web application in the real world behaves: a user accesses a page through a browser. Web applications show a landing page that requires users to enter valid authentication information. User entered user name and password. At this point we assume that the authentication information provided by the user is correct and that, through the valid

The principle of least privilege. The process of running scripts or executing code should be run with the least privileged account possible, thereby limiting the possible damage when the process is compromised. If a malicious user manages to inject code into a server process, the permissions granted to the process will largely determine the type of action that the user can perform. Code that
. United States L. Spizner is a famous Honeypot technology expert. He once made such a definition of the honeypot: The honeypot is a resource and its value is attacked or captured. This means that the honeypot is used to be probed, attacked, and eventually compromised, and that the honeypot does not fix anything, thus providing the user with additional, valuable information. The honeypot does not directly improve the computer network security, but it
