1.过滤所有客户端提交内容,包括?id=N一类,还有提交的html代码中的操作数据库的语名如select,及asp文件操作语法,可把提交的字付转义,再存入数据库
2.对访问Access数据库的页面进行授权,如对显示数据页面只能使用select语句,过滤别的什么update,asp文件分为许可访问数据库页面和限制访问页.
3.修改数库据连接文件名conn.asp为类似123ljuvo345l3kj34534v.asp文件
4.修改数据库名为类似q397d0394pjsdlkfgjwetoiu.asp文件
5.给Access数据库加上连接密码(虽然可以破解,对付菜鸟,和防止上传文件无限制连接数据库)

14.对连接服务的头内容进行限制,如只许可ie,火狐浏览访问
15.防止通过文件查看方式,得到数据库信息,可用客户端输入密码,对密码和内容,用一定算法存入数据库,输出时,让客户端输入密码,对内容进行解密
16.把表名和字段名改为aslkejrwoieru,werkuwoeiruwe类似的字符
