gunshot detection technology

want to write this method, you can use the method provided by the modernizr library to check whether the browser supports the video API: if(Modernizr.video){ do something}else{ do something } 4. Create an element, set a specific property value for the DOM object of the element, and check whether the browser retains the property value. To detect supportedType. First, create a virtualElement: var I = document. createElement_x_x ("input "); The default element is the text type. Next, set the eleme

The D language introduces static if, static assert, template, is and some other statements, so that D language can use the compile-time to perform logic processing, but also to compile-time testing, which allows the compiler at compile time on the custom class, structure, parameters for dynamic detection, This allows the definition of something with a strong type of function, the work of cow B. Import Std.stdio; Import Std.range; int Main (string[] ar

In the previous article, we will introduce anti-simulation technologies commonly used by malware to readers. 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 commo

Title: Introduction to Intrusion detection technology time: 2004-06-13 Source: http://www.meiclub.com/Abstract with the development of computer technology, especially network, computer system has been developed from independent host to complex and interconnected open system, This has brought great convenience to people in the use of information and the sharing of

From the simplest packet filtering firewall to the application layer gateway, since the date of birth, the firewall has increasingly assumed more and more network security role. In recent years, an innovative firewall technology is widely used, which is known as depth packet detection of dip (Deep Packet Inspection) technology.Historical ReviewBefore delving into the depth-pack

Author: Lin shanmao Status detection firewall is currently the most widely used firewall to protect against hacker attacks. However, as the number of Web attacks targeted at the application layer increases, the effectiveness of the status detection firewall is getting lower and lower in attack protection. Status detection firewalls are not designed speci

Domain Cache detection (DNS cache snooping) technologyIn a corporate network, DNS servers are typically configured to provide domain name resolution services for hosts within the network. These DNS not only resolves their own private domain name, but also recursively, requesting public DNS to resolve third-party domain names, such as baidu.com. To improve performance, it is common to use cached records to record resolved domain names, especially third

No active defense capability The IDs technology uses a kind of preset, characteristic analysis work principle, so the update of detection rule always lags behind the attack means update. 3.

Tongteng Network Shunt, also known as the core network collector, is an important basic equipment for the network monitoring front-end in the network security field. It is an essential equipment for the entire network security! It plays a key role in network security! Currently, the fixed network has been upgraded to 400 GB, supporting different links. The mobile Internet signaling collection traffic has been upgraded to a GB interface, supporting different carriers to separately distribute traf

cause IDS to be missed, if you consider supporting as many protocol types as possible, the cost of the network will be unbearable. 2. No active defense capability IDS technology uses a pre-setup and Feature Analysis working principle, so the update of detection rules always lags behind the update of attack methods. 3. Lack of accurate positioning and processing mechanisms IDS can only identify IP addresses

In the computer network, basically all uses the former one, but I also have seen can understand the latter's statement.The first time I came into contact with the CRC is the error detection sec

The Intrusion Detection System (IDS) is a new generation of security defense technology developed over the past decade. It collects and analyzes information from several key points in a computer network or system, whether there are violations of security policies and signs of attacks. This is a dynamic security technology that detects, records, alerts, and respon
