Many people are learning the Linux operating system, and the computer is essential to the operating system. The development of Linux is very rapid. Here we will introduce the knowledge of Linux, so that you can learn how to use Linux. Today I will talk about the top ten advanced security management skills in Linux. I hope you will remember the top ten advanced

(most commonly used), CFB, OFB, CTR. Padding (padding): Partial encryption mode, which needs to be populated in a specific way when the last block is less than 128 bits in length. (ECB, CBC needs to be populated, CFB, OFB, CTR does not need to be populated) Initialization vector (IV): Part of the encryption mode (CFB, OFB, CTR) will either perform or manipulate the plaintext block with the previous ciphertext block. For the first plaintext block, there is no previous ciphertext block, s

This is an invisible and complex threat. The anti-malware we rely on for a long time only creates a security illusion for us.In this article, we will discuss how to detect and prevent different types of products requ

In the process of managing and maintaining the LAN, network administrators may often encounter such a phenomenon, that is, some of the Internet users will often secretly use peer-to-peer tools in the local area network to download large volumes of movies or other multimedia data, this malicious download operation consumes the local area network limited valuable bandwidth resources, And it is easy to cause the entire LAN network can not run stably. In fact, we can take advantage of the new
