Wireless networks are more vulnerable to intrusion than wired networks, because the computers at the attacked end do not need to be connected to the computers at the attacked end, attackers can access your internal network and access resources as long as they are within the valid range of a wireless router or repeater in your domain. During the Olympic Games, when watching or directly participating in the event reports connected to wireless networks in public, what are the

An asymmetric key contains a database-level internal public and private key that can be used to encrypt and decrypt data in a SQL Server database, either imported from an external file or assembly, or generated in a SQL Server database. It is not like a certificate and cannot be backed up to a file. This means that once it is created in SQL Server, there is no easy way to reuse the same

. After obtaining the version number, they can search for vulnerabilities on the server, therefore, targeted intrusion using corresponding technologies and tools is also a key step in penetration testing. Therefore, to avoid unnecessary troubles and security risks, you can use the following two options in the main configuration file httpd. conf: 1)ServerTokens: This option is used to control whether the ser

Tutorial Background:Xiaonuo has used Linux to build various servers (FTP, DNS, Apache, Sendmail, and Samba), because these servers are placed in a safe place, generally, no one is allowed to access these servers. The company now needs to securely access these servers through remote clients. SSH is a standard network protocol that can be used in most UNIX operating systems to achieve remote login management on the Character interface. It uses port 22 by default and transmits data in the network i

unclear security policies written in the enterprise employee manual. For example, an employee may send an email containing important files to an incorrect recipient, or use a P2P file sharing website based on the network to send large files to business partners, they may not know that they have lost ownership and control of important data after uploading materials. The key to avoiding the problem is to let
