Redis is an open-source, in-memory, data structure store with optional disk writes for persistence. It can be used as a key-value database, or as a cache and message broker. Redis features built-in transactions, replication, and support for a variety of data structures such as strings, hashes, lists, sets, and others. Redis can be made highly available with Redis Sentinel and supports automatic partitioning with Redis Cluster.
下载Springsecurity源码之后,看到的是多个module的,即多个module组成Springsecurity。
Some contents of a web application are restricted, and only authorized users are allowed to view them, after they supplied the correct user name and password. The servlet technology supports applying security constraint to those contents via the configuration of the deployment descriptor (web.xml file). Now, in this chapter, we will look at how a web container supports the security constraint feature.
User对象是认证系统的核心。它们通常表示与你的站点进行交互的用户,并用于启用限制访问、注册用户信息和关联内容给创建者等。在Django的认证框架中只存在一种类型的用户,因此诸如’superusers’或管理员’staff’用户只是具有特殊属性集的user对象,而不是不同类型的user对象。
UsernamePasswordAuthenticationFilter: 用来根据传递进来的用户名及密码进行用户认证。
在之前了解了为什么所有的请求都会进行认证操作,我们也直接把目光放到源码中这个地方defaultSecurityFilterChain()

锁屏要使用指纹解锁,首先要注册指纹服务,我看过的一些大厂项目中,实际上是在KeyguardUpdate.java类中发起注册的,一般是根据当前状态,是不是已经处于上锁状态(侧边指纹机器,是不等上锁即进行指纹服务注册,屏下指纹需要等上锁后,才发起指纹服务注册)。

While use of an active challenge/response paradigm to confirm liveness of the subject in a biometric authentication system can greatly strengthen security, it also carries with it an added burden on the user. Requesting the user to perform specific extra actions can increase the time to authenticate, increases the likelihood of user error, and can lead to missed detections.
对于登录功能来说,为了防止暴力破解密码,一般会对登录失败次数进行限定,在一定时间窗口超过一定次数,则锁定账户,来确保系统安全。本文主要讲述一下spring security的账户锁定。
上一篇文章 浅析 Spring Security 核心组件 中介绍了Spring Security的基本组件,有了前面的基础,这篇文章就来详细分析下Spring Security的认证过程。
假设那你已经了解RESTful API的相关概念,如果不清楚,可以阅读我之前写的这篇博客Designing a RESTful Web API.
hostapd is an IEEE 802.11 AP and IEEE 802.1X/WPA/WPA2/EAP/RADIUS Authenticator. This page is dedicated to the Linux documentation of it’s implementation and use. Please refer to the hostapd home page for information for other Operating Systems. As far a Linux is concerned, out of the old drivers you can only use these 3 drivers with hostapd: HostAP madwifi prism54 All new mac80211 based drivers that implement AP functionality are supported with hostapd’s nl80211 driver. The mac80211 subsystem moves all aspects of master mode into user space. It depends on hostapd to handle authenticating clients, setting encryption keys, establishing key rotation policy, and other aspects of the wireless infrastructure. Due to this, the old method of issuing ‘ iwconfig <wireless interface> mode master’ no longer works. Userspace programs like hostapd now use netlink (the nl80211 driver) to create a master mode interface for your traffic and a monitor mode interface for receiving and transmitting management frames. Getting hostapd Using your distributions hostapd It is advisable to try your distributions version of hostapd before taking the time to compile and install your own copy. This will make future maintenance easier as you’ll be able to use the init scripts shipped by the distro and hostapd will be updated by it as well. If your distribution ships 0.6.8 or later, you can test with this bare minimum config by creating the file hostapd-minimal.conf: #change wlan0 to your wireless device interface=wlan0 driver=nl80211 ssid=test channel=1 If that config errors out with something like: hostapd $ sudo hostapd ./hostapd-minimal.conf Configuration file: ./hostapd-minimal.conf Line 2: invalid/unknown driver ‘nl80211’ 1 errors found in configuration file ‘./hostapd-minimal.conf’ that means that your distro is not shipping hostapd with nl80211 driver support and you’ll need to follow the building instructions that follow. If it works, you can skip down to the configuring hostapd secti

在restframework中自带认证组件,而其自带的认证组件是如何认证校验的呢:
安装完 ErLang 和 RabbitMQ 之后执行 rabbitmqctl status 报错:

在本教程中,我们将开发一个Spring Boot应用程序,该应用程序使用JWT身份验证来保护公开的REST API。在此示例中,我们将使用硬编码的用户和密码进行用户身份验证。

我曾经使用 Interceptor 实现了一个简单网站Demo的登录拦截和Session处理工作,虽然能够实现相应的功能,但是无疑Spring Security提供的配置方法更加简单明确,能够更好的保护Web应用。
ProviderManager中有如下List-1的属性,AuthenticationProvider就是被ProviderManager使用到的,如下List-2所示。
Spray Authentication 在Spray中,如果需要对REST API添加认证,可以使用Spray提供的Authenticate功能。本质上,Authenticate属于安全指令(Security Directive)提供的功能。它的接口定义本质上为: def authenticate[T](auth: => Future[Authentication[T]])(implicit executor: ExecutionContext): Directive1[T] def authentica

I recently got a chance to play around with Tornado, which is pretty neat (although that certainly isn’t news). One thing that I tried to do pretty quickly and had a hard time with was Basic authentication (you know, the little “so-and-so requires a username and password” pop-up). Paulo Suzart posted a working example over on gist, but it was a bit light on context, and Dhanan Jaynene’s request interceptors are a bit overkill for this purpose (although very useful for more complex behavior!). Let’s start with the “hello world” example from theTornado site, and I’ll show you what I’ve cooked up. I’m only an hour or two into exploring Tornado, like I hinted at above, so if you see any room for improvement, I’d love to hear from you. (I’ve made all the code I’ve written very verbose in the hopes that’ll help people understand and customize it without much trial-and-error. Feel free to tighten things up.)

其实只要看懂了松哥前面的文章,这个需求是可以做出来的。因为一个核心点就是 ProviderManager,搞懂了这个,其他的就很容易了。
