Web security is divided into three aspects: protecting the security of the server and its data; protecting the security of information transferred between the server and the user; and protecting the security of the web application client and its environment.

Web security is divided into several aspects

With the birth of a series of new Internet products such as Web2.0, social networks, Weibo, etc., Internet applications based on the Web environment are becoming more and more widespread. , in the process of enterprise informatization, various applications are set up on the Web platform. (Recommended learning: web front-end video tutorial)

The rapid development of the Web business has also attracted strong attention from hackers. What follows is the emergence of Web security threats. Hackers use the website operating system Vulnerabilities and SQL injection vulnerabilities in web service programs gain the control authority of the web server, ranging from tampering with web page content to stealing important internal data. Even more serious, malicious code is implanted in web pages, exposing website visitors to infringement.

Web application security issues essentially stem from software quality issues. However, web applications have their own uniqueness compared with traditional software.

Web applications are often unique to an organization. For vulnerabilities, known common vulnerability signatures lack validity; they need to be changed frequently to meet business goals, which makes many It is difficult to maintain an orderly development cycle; it is necessary to fully consider the complex interaction scenarios between the client and the server, and often many developers do not understand the business process well; people generally think that web development is relatively simple, and even inexperienced developers can do it.

Web application security should ideally follow secure coding principles throughout the software development life cycle and take corresponding security measures at each stage.

However, the actual situation of most websites is that a large number of early-developed Web applications have security problems of varying degrees due to historical reasons. For these web applications that have been launched and are being produced, due to their customized characteristics, no universal patches are available, and code rectification is difficult to implement or requires a long rectification cycle because of the high cost.

In this situation, professional web security protection tools are a reasonable choice. WEB Application Firewall (hereinafter referred to as WAF) is just such a professional tool that provides a means of security operation and maintenance control: based on two-way analysis of HTTP/HTTPS traffic, it provides real-time protection for Web applications.

Common WEB security products include Barracuda WEB Application Firewall.

Caddy has the following main features: Compared with the complex configuration of Nginx, its original Caddyfile configuration is very simple; it can dynamically modify the configuration through the AdminAPI it provides; it supports automated HTTPS configuration by default, and can automatically apply for HTTPS certificates and configure it; it can be expanded to data Tens of thousands of sites; can be executed anywhere with no additional dependencies; written in Go language, memory safety is more guaranteed. First of all, we install it directly in CentO

Real-time protection against face-blocking barrages on the web (based on machine learning) Real-time protection against face-blocking barrages on the web (based on machine learning) Jun 10, 2023 pm 01:03 PM

Face-blocking barrage means that a large number of barrages float by without blocking the person in the video, making it look like they are floating from behind the person. Machine learning has been popular for several years, but many people don’t know that these capabilities can also be run in browsers. This article introduces the practical optimization process in video barrages. At the end of the article, it lists some applicable scenarios for this solution, hoping to open it up. Some ideas. mediapipeDemo (https://google.github.io/mediapipe/) demonstrates the mainstream implementation principle of face-blocking barrage on-demand up upload. The server background calculation extracts the portrait area in the video screen, and converts it into svg storage while the client plays the video. Download svg from the server and combine it with barrage, portrait
