can use it to obtain the root permission and then control the entire system. 3. obtain the latest Apache Using the most secure version is crucial to enhancing the security of Apache Web servers. You can get the latest Apache version from the official Apache website http://www.apache.org. Protection of configuration files The Apache Web server has three major configuration files, which are generally located

://www.apache.org. Protection of configuration files The Apache Web server has three main configuration files, which are typically located in the/usr/local/apache/conf directory. These three documents are: Httpd.con, srm.conf and access.conf. These files are the control center of the entire Apache, so you need to know about three profiles. The httpd.conf file is the primary configuration file; srm.conf al

As a network engineer, ensuring the security of enterprise servers and normal operation is the primary issue in network management. So how can we effectively protect the security of servers? Based on my work experience over the past decade, I have established a protection system from the following seven points. Entry Point 1: Establish a strong network security system To isolate an enterprise's servers and "Protect" them one by one, as the core comp

redirection, IP routing, and other technologies. In 2009, Microsoft released its security report (Advisory 973811), which provided two mechanisms: service binding and channel binding. Service-binding requires the client to provide the signed SPN into the authorization information. If an attacker attempts to use a certificate obtained from linked information or does not provide a signed SPN, it will not be able to connect to SQL Server, which has litt

Microsoft Azure Backup implements file-and folder-based backup and recovery, and Microsoft Azure recently provides backup and recovery of application workloads for enterprise on-premises environments, such as Microsoft SQL server,hyper-v virtual machines , SharePoint Server,microsoft support for the long-term retention of disk-to-disk backup of the local copy (D2D) and disk-to-disk-to-Cloud (D2D2C) Backup o

Specific measures for server security protection: 1. Start with the foundation and provide basic protection. First, convert all the disk partitions on the server that contain sensitive data to the NTFS format. Second, whether it is Windows or Linux, any operating system has vulnerabilities, and patch the vulnerabilitie

physically accessed by attackers. One is to set a password for the bios, and the other is to configure the password protection (Password = xxx) System Startup Process in the/etc/Lilo. conf file. However, remember that once the system is completely physically exposed by intruders, there is no way to ensure the absolute security of the system. 6. ipchains Discussing Linux security is not possible without discussing ipchains. Ipchains is the package fil

and use formulas to standardize scripts, which will be of great help to our future work. In this section, we compile a simple iptables syntax rule for mail host protection. The network topology is very simple. the IP address of the iptables machine is 192.168.1.101/24, and the IP address of the other machine is 192.168.1.102. Common email host protection script The normal mail host

servers "! Temporary protection DHCP As we all know, the common workstation system sends the request information of the Internet parameters to the LAN network through broadcasting. All network devices in the LAN will receive requests from the common workstation, this naturally includes valid DHCP servers and invalid DHCP servers. However, whether the DHCP server is a valid DHCP

tips are also useful for IIS administrators who have a strong budget. First, develop a set of security policies The first step in securing your Web server is to ensure that your network administrator is aware of every system in your security policy. If the company's executives do not regard the security of the server as an asset that must be protected, then the protect
