To establish a secure Linux server, you first need to understand the meaning of the configuration files that are related to the network service and how to configure them securely in the Linux environment. In a Linux system, TCP/IP networks are configured with several text files, and you may need to edit these files to complete networking, but most of these profiles can be configured with command Linuxconf (where the configuration of the network portio

SSH through gateway to implement port forwarding Compared with the previous on two virtual machines via SSH port forwarding to achieve secure communication, this experiment in two virtual machines to join the gateway. First, the experimental environment: Three Linux virtual machines, VM1 (172.16.1.2) belong to the Vmnet1 subnet, vm2 (172.16.2.2) belong to the Vmnet2 subnet, gate as a gateway, with two virtual network card, not belong to Vmnet1 and

that is not easily attacked by a cache overflow. If you want to avoid such problems completely, you can only write code without using a language that accesses memory directly. You can use scripting languages (for example, JavaScript, Perl) or use explanatory language (such as Java). If you write code in a secure language, your Web site's operators can be freed from a security attack such as a cache overflow every day. In addition, you should not blin

challenges: § Use routers to configure access control lists to achieve border security control, but the function is weak, can not effectively protect the network. § has a small number of firewalls, but without centralized control, security needs to be improved. § Static password protection device, it is easy to get control by hackers, which leads to the security of the whole network down. Solution Introduction Check Point works with Opsec (Open Platform for Security) partner I-security to provi

access data that is not authenticated. However, if other users on the server host have direct access to the contents of the data directory, the will not be able to establish good security for the network accessing the data. Unless you know that you are the only person registered on a machine running a MySQL server, you need to be concerned about the likelihood that other users on that machine will have access to the data directory. Here's what you want to protect: Database files. It is obvious
