A study has shown that 1% of passwords can be guessed within 4 times. How could it be? simple! Try four most common passwords. password,123456,12345678, and QWERTY, which opened the door of 1%. Well, you're one of those 99%, but you also have to think about the speed of hacking software today. John the Ripper is a free hacker software that can test millions of passwords per second. There is also a commercial software used in the Criminal investigation field (in the seizure of the computer to f

At present, the attacks on the web increasingly, denial of service attacks, phishing, SQL injection and so on, and Enterprise Portal is the enterprise's "face", how to ensure that its security is operational maintenance personnel, security managers, CIOs need thoughtful, comprehensive consideration of the problem. This article will focus on this problem, first to the Enterprise Portal Web system detailed security threat analysis, and then give the corresponding solution principles and techniques

you hire a consulting firm to perform penetration testing for your software. Many people refer to this test as a "black box" (based on a warranty technique with the same name), and testers do not have detailed system internals (such as system code). After the test is executed, a report is invariably generated that outlines several types of vulnerabilities in your application. You fix the vulnerability and then submit the application for regression testing, and the next report says "cleared"-tha

This article aims to summarize some things and solve the main problems encountered when attempting to construct a Vulnerability Database, that is, how to classify computer network vulnerabilities. Some of the ideas in this article are not mature, and some are not even satisfied with themselves, so as to communicate with colleagues who have in-depth research in this area and improve the work together. A computer network security vulnerability has its many attributes. I think it can be summarized

Network SecurityAccording to the investigation, in many cases, it is caused by "Insiders" rather than external hackers. According to a survey conducted by an authority in China on senior IT managers of large carriers, 66% of managers believe that terminals can be freely accessed,IntranetResource abuse and misuse, business data leakage, and viruses are the most serious security threats. In comparison, only 13% of the most serious

development of Internet technology, various P2P applications are also widely used in campus networks. As a popular download method, various P2P applications allow users to easily find their desired network resources. However, a large number of unrestricted P2P connections will greatly consume network bandwidth resources, bring great troubles to the normal network services of xigong University, and also bring some security risks. In addition, because there are many student machines in the campus

How to solve the security problems faced by WLAN Access and ensure customers' safe use is an important issue. The security challenges facing wireless networks are analyzed carefully, mainly to prevent illegal AP access, prevent illegal user access, prevent ARP attacks, prevent AP overload, and prevent unreasonable applications. Both external

With the gradual upgrade of the Internet, both sides of Web attacks and Web Protection have launched a new round of tug-of-war. From quietly allowing malicious software to sneak in to users' systems for illegal downloads, to redirecting users to malicious advertisements of fake Anti-Virus products that attempt to extort money, the Internet world is filled with various unknown threats. In the face of this new pattern, traditional protection methods can

amount of system information and even provide methods to directly access Web service data without authentication, becoming an effective source of intelligence for malicious users to analyze and attack Web servers. In addition, the existence of these files also implies that the website has potential security vulnerabilities.3) Search for the Administrator Logon pageMany network products provide Web-based management interfaces that allow administrators to remotely manage and control them on the I

In recent years, along with the development of computer networks and communication technology, it not only brings great convenience to people's lives, but also enables people to enjoy more material and culture. At the same time, network security threats are becoming more and more serious, such as hacker attacks, data theft, and virus release. Although we are also using complex software technologies such as firewalls, anti-virus software, and intrusion

This article introduces the advantages of cloud security compared with general security and hopes to help you. 1. Analyze the Local Area Network Security Threats Insiders believe that the threats to the internal network of the Organization mainly come from outside the Organization, but from inside the organization. Therefore, it is wrong to focus on preventing the network from being attacked from outside th

Levenitz, the founder of calculus, once had a famous philosophical saying: "There are no two identical leaves in the world." taking humans as an example, although scientific research has long proved that among the more than 7 billion people in the world, even twins cannot be identical, but two people with the same birth, name, appearance, or even sound are everywhere. In the era of cloud computing and big data, massive volumes of information are encapsulated into packets that are transferred ove

In today's busy IT networks, there are always new security viruses. Therefore, patch management has become the most basic management task. Some companies do not take any measures to protect themselves before being attacked, while others do not consider patching as much as possible. Patch a network is divided into two steps: first, scan the machine to see what patches are missing, and second, attach the patches to your system as soon as they are released. Using the automatic patch management solu

0. Introduction With the development of wireless technology and network technology, wireless networks are becoming a hot spot in the market. However, with the improvement of hacker technology, wireless LAN (WLAN) is under more and more threats. Wireless networks are not only attacked based on the traditional wired network's TCP/IP architecture, but may also be threatened by security issues based on the IEEE 802.11 standard. In order to better detect a

The school computer room is the hub of School Informatization. In order to ensure the normal operation of the computer room system, a series of preventive and optimization measures are required to address different security threats from various sources. Human threat The computer room undertakes overload teaching tasks such as students' hands-on exercises in the classroom and after-school hands-on experiments. Due to the imperfect data center managemen

Nowadays, enterprises have many choices to protect the network from external attacks. For example, firewall is a good choice. In most cases, it can distinguish abnormal data packets, therefore, we can take timely measures to prevent problems before they happen. However, for most enterprises, IDS is the best choice to completely isolate potential threats. Intrusion detection and defense are generally used together with the enterprise's first firewall,

I. Current situation and problems? ? ? ? With the "Cyber Security Law" formally becoming a law and regulations, level protection series of policy updates, "security" for most enterprises has become a "mandatory." However, the security situation of cyberspace is increasingly complex and grim. The worldwide outbreak of ransomware virus has a huge impact on the normal work of enterprises. Advanced Persistent threats (apt***), Harpoon * * *, internal staf
