  1. Nginx 6.利用上传文件钓鱼 服务器302跳转漏洞防御1.文件上传目录设置为不可执行,上传文件做静态文件处理2.判断文件类型,such as 增强型MIME sniff3.使用随机数改写文件名和文件路径4.单独设置文件服务器的域名认证的目的是能认出用户是谁,授权的目的是为了决定用户能够做什么认证实际上就是一个验证凭证的过程,比如账号密码单因素认证与多因素认证密码必须以不可逆的加密算法,或者是单向散列函数算法,加密存储在数据库中登陆过程就是验证用户提交的密码的哈希值,与保存在数据库中的密码哈希值是否一致。为避免黑客获取哈希值后通过彩虹表查询明文密码,在计算密码明文的哈希时,会加Salt MD5(Username Password salt)当用户登陆后需要替换一个对用户透明的凭证,不能每次请求页面都要输入账号密码,这个凭证就是session ID,session ID一旦在生命周期内被窃取,就等同于账户失窃。session fixation攻击1.session ID保存在URL中,X诱使Y去打开链接完成认证2.在Y登陆完成后,session ID不变(防御就是改写session ID)session劫持,如果session在cookie中存放,也叫cookie劫持session保持攻击,获取session后,黑客通过不断的请求,使session活下去防御1.一定时间后,强制销毁session2.当用户IP, Useragent发生变化时,强制销毁当前session,并要求重新登录权限是一种能力,对于权限的合理分配,一直是很重要的命题Linux文件系统中,将权限分出了读,写,执行。用户可能只有读的权限根据访问客体的不同,常见的访问控制分为1.基于URL的访问控制2.基于方法(method)的访问控制3.基于数据的访问控制垂直权限管理建立用户与权限的对应关系,就是『基于角色的访问控制』(Role-based Access Control)一个角色就是权限的集合基于URL的访问控制,不同的URL对于能访问其的角色有不同的要求基于method的访问控制,配置文件比较复杂,且更新麻烦越权访问:低权限的角色访问高权限角色的权限水平权限管理水平权限问题出在同一个角色上。系统只验证了角色,却没有对角色做细分,缺乏一个用户到数据的映射关系。所以水平权限管理也称为『基于数据的访问控制』利用合理的请求造成资源过载,导致服务不可用常见的DDOS,SYN flood,UDP flood,ICMP flood网络层DDOSSYN flood利用了TCP协议设计中的缺陷,首先伪造大量的源IP,分别向服务器发送大量的SYN包,此时服务器返回SYN/ACK包,但是由于IP是伪造的,所以无应答,而服务器将会重试3-5次并等待SYN time导致CPU与内存资源大量消耗而无暇顾及正常的访问请求解决方法:对每一个IP分配一个cookie,并统计每一个IP地址的访问频率应用层DDOS三次握手已经完成,IP地址也是真实的CC攻击对一些消耗较大的应用页面不断发起正常的请求,如web中查询数据库,读写硬盘操作解决方法:1.使用频率高的数据放在memcache(绕过的方法自然是穿透memcache),将数据库的压力尽量转移到内存2.验证码,验证码消耗掉后要更新session ID,否则使用原有的session ID可以重复提交同一个验证码防御应用层DDOS验证码的核心是识别人与机器靠谱的方法是让客户端解析一段Java Script,并运行出正确的结果资源耗尽攻击slowloris攻击,构造畸形的http请求,以极低的速度发往服务器端,是web server并发连接数达到上限。此类攻击的本质,实际上是对有限的资源的无限制的滥用,通过调整参数可以缓解这种攻击。server limit DDOS,通过XSS写入超长cookie,导致HTTP包头超过限定大小,导致无法访问cookie所在域的任何页面文件包含漏洞,代码注入的一种include() require() include_once() require_once(),使用这四个函数包含一个新文件时,该文件将作为php代码执行,PHP内核并不会在意被包含的文件是什么类型。?
