The command corresponding to this command is lsattr, which is used to que

The security of Unix operating systems is well known. However, if you want to say where the Unix system is secure, it is estimated that no one can say why. 1. Different users have different permissions for the same command. The Date command is a common command in Unix systems. It displays the Date and time of the system. However, different user roles have differe

, including technical and service indicators, and assigns the corresponding weights, this constitutes a key indicator system for this selection. The output of work at this stage is a score table that includes key indicator systems. 2)Filter suppliers and determine alternative platforms In this phase, suppliers are compared and scored based on the key indicator system and scoring table. Select the preferred suppliers based on the platform technical lev

Today, with the rapid evolution of Web technology and the vigorous development of e-commerce, many new applications developed by enterprises are Web applications, in addition, Web services are increasingly used to integrate or interact with Web applications. These trends bring about the following problems: the growth of Web applications and services has exceeded the security training and security awareness

better than the switch, and the hardware firewall is the first choice. 3. upgrade your software In many cases, it is critical to perform a patch test on the system before you install and deploy the productive application software. The final security patch must be installed in your system. If the security upgrade is not performed for a long time, the computer you use may easily become the target of an immor

Before giving you a detailed introduction to the smart wiring management system, let's first understand the principle and mechanism of the smart wiring management system, next, we will introduce the EtherSeal cabling system to ensure network security, provide reliable solutions for high-density intelligent Cabling Management Systems, and make up for security mana

, read the blocks that contain the file content in the order in which the block numbers appear in the disk address table. Therefore, apart from root, you must never make the disk partition writable to everyone. because the owner and the file access permission are stored in the I node, the owner can set the suid permission for all files as long as he has a write permission for the installed partition, no matter who the file owner is, you do not need to use the chmod () command. You can also avoid

I am often asked this question: How can I evaluate the security of a software system? One answer is: do we have specialized software security evaluation standards and institutions? Yes, we have specialized international standard common criteria, ISO/IEC 15408, and National Standard GB 18336. There are specialized evaluation centers, such as common criteria lab and China Information

With the advent of Windows Server 2003, many people can use the leaked version, relative to the workstation system, where the server is To do more kernel optimization, so there is a great improvement in stability and security. However, many people do not need the full server department, and the server system shuts down the services required by some workstation systems, below, we will optimize the Windows Se

As we all know, network security is a very important topic, and servers are the most critical link in network security. Linux is considered to be a safer Internet server. As an open-source operating system, once a security vulnerability is found in Linux, volunteers from around the world on the Internet will actively fix it. However, system administrators often c

For the wide variety of Intranet security software on the market, the system title, technical standards, and so on lack of relevant standards and specifications, there are both "Foreign Affairs" products, there are also some vague concepts promoted by local enterprises, and there are also a series of grassroots sayings. The absence of such industry-wide norms has largely led to a
