systems are "automatically inspected every 21 times of mounting the file system or every 180 days. In practice, ext2 and ext3 are at risk in automatic detection. Sometimes the file system enters the single-user mode after it is started, and the entire system is "thrown" into the lost + found directory, if you want to recover the system, you must use fsck to fix it. Of course, fsck also has risks. Therefore, you must be prepared for the use of ext2 and ext3 file systems; after all, it is difficu

Enterprise IntranetFor the risks faced by an enterprise's network security and to fully assess the risks that these risks may bring, they will be the primary problems that must be addressed during the implementation of security construction and the basis and basis for formulating security policies. So what security risks do enterprises have? What value can Enterprise Intranet security products bring to enterprises? Huang Kai, R D Director of Yixin technology, learned about the information, user

Intranet Security Status Quo Analysis The theory of Intranet security is relative to the traditional network security. In the traditional network security threat model, it is assumed that all the personnel and devices in the Intranet are secure and trusted, while the external network is insecure. Based on this assumption, Internet security solutions such as anti-virus software, firewall, and IDS are generated. This solution prevents external intrusion, but it is helpless for internal security pr

Intranet confidentiality is a major event for enterprises. network administrators can reach a consensus with the enterprise's top management and adopt appropriate measures to keep the network confidential for leaks of personnel and mobile devices. Personnel Leak Prevention Leaks by computer operators are currently the most serious victims of leaks. They may cause leaks in the following ways: 1. Ignorance. For example, if you do not know that the compu

Before talking about the ORACLE view, let's take a look at this requirement first. There is a teacher information table with the following fields: teacher ID, name, marital status, ID card number, and substitute subject. You can view the marital status and ID card number from the academic affairs office, however, it is prohibited for students to view and keep them confidential. The two identities use the same table. How can I view different results? B

In daily work, protecting data from unauthorized users is a special concern of system administrators. If you are currently using MySQL, you can use some convenient functions to protect the system, greatly reducing the risk of unauthorized access to confidential data. The most valuable asset of an enterprise is usually the customer or product information in its database. Therefore In daily work, protecting data from unauthorized users is a special conc

course, there is no doubt about the security awareness of some confidential personnel. For some general personnel who may occasionally access confidential information, strict requirements should also be imposed on the handling of file spam.In addition to file materials, there are also unnecessary computer media that must be ensured to be retained or completely deleted; cleaning personnel should be well man

There are several ways to persist data in OC, such as writing a file or archiving it. How to write a file we can generally read the data in the file directly. For example, I write the data into a XX.txt document. Only if the data is written successfully, I can read the file directly. However, for some users the key data does not play a secret role, if the need to keep confidential also need to use the archive operation.Operation of the fileFirst decla

In recent years, many companies have leaked data, causing heavy losses to the affected enterprises and even facing the risk of bankruptcy. In order to prevent the occurrence of leaks, many enterprises have installed Super eye computer monitoring softwareOne of the functions is the real-time alarm of employees on the computer. Once there is any violation, an alarm will be triggered immediately, for example: insert a USB flash drive alarm, copy to USB flash drive alarm, hardware change alarm, trig

Build DMZ with Linux Firewall Summary To provide different security levels for different resources, you can consider building a region called "demilitarized zone" (DMZ. DMZ can be understood as a special network area different from the Internet or intranet. DMZ usually stores some public servers without confidential information, such as web, mail, and FTP. In this way, visitors from the Internet can access services in DMZ, but they cannot access c

then directly receive data at the IP layer.Of course, the function of this program is too simple. Only simple information such as the source address, target address and source port, and target port can be displayed, which is of no use to hackers, hackers need information such as passwords, which can be completed using some free sniffer programs. Meaning and working principle of sniffer: 1. Meanings of Sniffer and snifferSniffers (sniffer) has nearly the same history as Internet. sniffer is a

content of information security, and puts forward some measures to protect and prevent the author's information. Throughout the book, I personally think that Part 1-the art of the attacker, the content is very exciting, through a "thrilling" story, explains how hacker uses social engineering to intrude into the system to obtain sensitive or even confidential information. Hacker uses its omnipotent technologies and superb social engineering capabilit

Web2.0 is a new term used to describe new-generation network applications. Start.com, Google Maps, writely, and Myspace.com are typical web. 0. The continuous advancement of technology has promoted the development of Web applications. In terms of network services, it enhances the core technical components of the server, while in terms of clients, Ajax and rich network applications (RIA) Improve the client user interfaces in the browser. XML has a huge impact on the presentation layer and transpo

algorithms, this method is also called asymmetric encryption algorithms ". Unlike symmetric encryption algorithms, asymmetric encryption algorithms require two keys: public key and private key ). A public key is a pair of private keys. If a public key is used to encrypt data, only the corresponding private key can be used for decryption. If a private key is used to encrypt data, only the corresponding public key can be decrypted. Because encryption and decryption use two different keys, this a

After installation, goHttp://www.truecrypt.org/localizationsDownload the Simplified Chinese Language Pack, decompress it to the truecrypt installation directory, run truecrypt, and select the "language" option in the "setting" menu, in the displayed dialog box, select "simplified Chinese.2.

In fact, everyone's computer also needs such a "Shredder" to completely delete unnecessary confidential documents and wi

whether the data packet is aggressive. Most IDS matching algorithms are similar to the multi-mode detection algorithm of Snort, an open-source Intrusion Detection System. exception detection is another IDS detection method, which is usually used as a supplement to feature matching. In the face of a variety of network attacks and intrusions, this technology needs to be constantly improved. Currently, wireless network security products are developed based on Intrusion Detection. In fact, such sec

How to encrypt the PHP source code and how to encrypt the PHP source code without allowing others to see ------ solution ------------------ haha, zend has a dedicated encryption. The code is very messy. it is used in all 18 languages. each file is added with 1000 or 2000 lines of useless code. do not wrap the lines, and paste some garbled characters to keep them confidential. The best result is a helloworld with 20 thousand lines of code! ------ Solut

speed reaches several megabytes or dozens of megabits per second. Symmetric cryptographic systems are widely used due to these features. Because algorithms do not need to be kept confidential, manufacturers can develop low-cost chips for data encryption. These chips are widely used in large-scale production. The biggest problem with symmetric encryption systems is the complexity and high cost of key distribution and management. For example, for netwo
