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 three 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 compon
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.

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

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
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.

Solution Solutionsfor users, Default Trace you can only turn off or turn on the trace, and you cannot modify any parameters. Therefore, we only have to synchronize the trace files to save.

Next we have a detailed understanding of the DDoS attack protection capability and its settings:
The user can turn on/off the DDoS firewall function by clicking the "turned on"/"Closed" button at the top right of the action interface. It is recommended that users install the server security dog and immediately turn on the DDoS firewall. The ability to defend against DDoS attacks is only enabled

Application protection level for IIS:
A. Low (IIS Process): Web applications run in the Inetinfo.exe process with the highest performance, but with the greatest risk, when an application error occurs, the entire IIS server may be unavailable.
