gunshot detection technology

Over the years, companies have relied on stateful detection firewalls, intrusion detection systems, host-based anti-virus systems and anti-spam solutions to ensure the security of enterprise users and resources. But the situation is changing rapidly, and the traditional one-point defensive security device faces a new attack that is hard to handle. In order to detect the latest attack, the security device mu

315 hack First, we need to know what a backdoor program is? The common explanation of "backdoors" on the Internet can be summarized in a very simple sentence: backdoors are stored in computer systems, you can control the computer system in some special way !! -Obviously, mastering backdoor technology is an indispensable basic skill for every network security enthusiast! It allows you to stick to bots and never fly out of your fingers! Because of this,

detection, we can completely fill the split part into a monochrome for subsequent recognition. However, before the real recognition starts, we still need to perform some operations on these images. 1. The scaling operation scales the image to be recognized to a specified size. a scaling operation can ensure that the image details are not lost but as small as possible to accelerate the recognition speed, I use 24x24 here, mainly because the verificati

Exception Server Detection Technology Used by Netflix In the early morning, half of our technical support team was still investigating the cause of Netflix's error. The system seems to be running normally, but we cannot find anything wrong. After checking for an hour, I finally found a problem with a server in the data center. We have been looking for any obvious problem, and there are tens of thousands of

-based content identity technology, in order to achieve higher deduplication speeds than byte levels and a wider Duplicate content detection range. The main methods to determine the block boundaries are divided into two categories, including fixed-length chunking and variable - length chunking. L fixed block Then the process of calculating the fingerprint of each tile, and sift through the duplicate

Virtual Machine Detection Technology AnalysisAuthor: riusksk (quange)Home: http://riusksk.blogbus.comPrefaceIn today's information security field, especially in malware analysis, virtual machine technology is often used to improve the security of the virus analysis process and the constraints on hardware resources, therefore, it is widely used in the field of mal

In the last two years, security experts should pay more attention to attacks at the network application layer. No matter how strong firewall rule settings you have or how often you fix vulnerabilities, if your network application developers do not follow the security code for development, attackers will access your system through port 80. The two most widely used attack technologies are SQL injection [ref1] and CSS [ref2] attacks. SQL injection refers to the

Survey of intrusion detection technology 1. What is intrusion detection, why need intrusion detection? 1.1 Why intrusion detection is required 1.1.1 hacker attacks are rampant and the problem of prevention is becoming more severe With the development of computer

SQL injection technology and cross-site scripting attack detection (1) 1. Overview In the past two years, security experts should pay more attention to attacks at the network application layer. No matter how strong firewall rule settings you have or how often you fix vulnerabilities, if your network application developers do not follow the security code for development, attackers will access your system th

First, the Reverse debugging technology Anti-debugging technology is a common kind of counter detection technique, because malware always attempts to monitor its own code to detect if it is being debugged. To do this, the malware can check whether its own code is set to break the point, or directly through the system to detect the debugger. 1. Breakpoint In order

When we run SQL Injection on a server running IDS system, we often encounter a lot of trouble because our injection statements are filtered out, how to circumvent this kind of detection method has become a new technology. This article puts forward eleven ideas and methods for this technology, and discusses them with everyone.I. Bypass Using encoding

In this article, we will introduce various anti-Debugging techniques used by malware to impede reverse engineering, so as to help readers better understand these technologies, this enables more effective dynamic detection and analysis of malware.I. Anti-debugging technology Anti-debugging is a common anti-detection technique, because malware always tries to monit

injection and CSS Attack Vulnerability Detection Technologies. There have been a lot of discussions on these two WEB-based attacks, such as how to launch attacks, their impact, and how to better compile and design programs to prevent these attacks. However, there is not enough discussion about how to detect these attacks. We use the popular open-source IDS Snort [ref 3] to construct a regular expression based on the rules used to detect these attacks

This new technology was first developed by jquery and supported by prototype and mootools. The reason for the rise of this technology is that browser sniffing technology is not very reliable. For example, useragent is easily forged. For example, useragent of IE8 contains many browser keywords, making it difficult to identify. Some other important identification m

Newbie takes webshell for the first time and uses the bypass intrusion detection technology Of course, the target website for intrusion detection is owned by the Japanese Empire. Site: www.newtb.co.jp first found the injection point. I scanned the tool and found no vulnerabilities in the scope of my capabilities. Then I used Yu Jian to find the vulnerability. T

I haven't made a summary for a while. I don't know what I'm busy with every day! Now it takes an hour to summarize the learning in the last few days. Edge detection technology is the first step in image analysis. It uses the extreme values of the first derivative of the image or the zero point information of the second derivative to extract the edge. To put it simply, it is the problem of gray-scale image c
