web安全框架,主要用servlet filter方式覆盖httpServletRequest和HttpServletResponse方式增加一些输入输出的过滤,
主要实现的安全包括:
-
XSS过滤(获取用户输入参数和参数值进行XSS过滤,对Header和cookie value值进行XSS过滤(转码Script标签的< > 符号),
-
对Response的setStatus(int sc, String sm)方法 sm错误信息进行XSS过滤;
-
对Header的CLRF进行过滤;
-
对cookie大小和cookie的白名单进行验证;
-
对文件上传后缀白名单进行验证;
-
对只允许POST提交的url进行验证;
-
CSRF攻击 tokenID防御支持;
-
SESSION通过加密存储到cookie支持;
-
静态资源路径去除../上级目录符号;
使用指南:只需要在web.xml中配置对应的filter即可。
HttpSessionCookitStoreFilter是session存储到cookie的支持,encryKey加密密钥;
DefaultBaseSecurityFilter是默认的安全过滤filter,
securityFilterList可以配置对应的filter;
CookieWhiteListFilter:cookie白名单配置,如果配置这个,则需要配置参数cookieWhiteList;
CsrfTokenCkeckFilter:对post表单提交进行csrf token验证;使用CsrfTokenIdCreator生成csrf tokenid后放入表单还有session中,key名称必须为csrf_开头;为了支持多个form表单;
FileUploadSecurityFilter:文件上传后缀白名单验证,需要配置whitefilePostFixList参数;
FormPostPermitCheckFilter;只允许post提交的url列表,需要配置onlyPostUrlList参数;
redirectWhiteList:是配置重定向白名单url参数;
StaticFilePathSecurityFilter:url的../上级路径过滤;
