用JAVA做一个网站,现在要做防止XSS攻击,请问怎么防止这种攻击

过滤特定符号pre t="code" l="java" public static String guolv(String a) {

a = a.replaceAll("%22", "");

a = a.replaceAll("%27", "");

a = a.replaceAll("%3E", "");

a = a.replaceAll("%3e", "");

a = a.replaceAll("%3C", "");

a = a.replaceAll("%3c", "");

a = a.replaceAll("", "");

a = a.replaceAll("", "");

a = a.replaceAll("\"", "");

a = a.replaceAll("'", "");

a = a.replaceAll("\\+", "");

a = a.replaceAll("\\(", "");

a = a.replaceAll("\\)", "");

a = a.replaceAll(" and ", "");

a = a.replaceAll(" or ", "");

a = a.replaceAll(" 1=1 ", "");

return a;

}

java的框架(比如struts2)对于xss攻击、sql注入等黑客方式有防御么?

框架本身并不具有这些功能。

防止xss,sql等的攻击大部分需要程序员自己注意。

sql注入本身就是sql语句写法的漏洞导致。

xss攻击的防御还是需要对非法字符串进行判断过滤。

启动JAVA程序时,参数-Xms及Xmx有什么用

个人之见,欢迎指正:

Xmx是java的一个选项,用来设置你的应用程序能够使用的最大内存数(看好,致使你的应用程序,不是整个jvm),如果你的程序要花很大内存的话,那就需要修改缺省的设置,比如配置tomcat的时候,如果流量啊程序啊都很大的话就需要加大这个值了,不过有一点是要记住的,不要大得超过你的机器的内存,那样你的机器会受不了的,到时候就死翘翘了。

Xms是另一个设置内存的参数,用它来设置程序初始化的时候内存栈的大小,增加这个值的话你的程序的启动性能会得到提高。不过同样有前面的限制,以及受到xmx的限制。

另外,一个操作系统通常都只使用jvm,这就是你说的“运行在同一个JVM中的程序”,不同的虚拟机的实现虽然千差万别,但是他们的运行模式都是一样的,只是性能有所不同罢了。

远程文件包含漏洞 java web中有吗

javaweb中也有漏洞呀,比如XSS攻击,方法没有过滤,接口任何人都能访问,这也属于漏洞

Struct2+Spring 架构JavaWeb项目,出现xss跨站脚本攻击漏洞解决方案??

没用到富文本的话可以用spring里的HtmlUtils.htmlEscape(string str)来对parameter转码。是用filter还是其他方式都可以

xss是什么意思?

XSS攻击通常指的是通过利用网页开发时留下的漏洞,通过巧妙的方法注入恶意指令代码到网页,使用户加载并执行攻击者恶意制造的网页程序。这些恶意网页程序通常是JavaScript,但实际上也可以包括Java、 VBScript、ActiveX、 Flash 或者甚至是普通的HTML。攻击成功后,攻击者可能得到包括但不限于更高的权限(如执行一些操作)、私密网页内容、会话和cookie等各种内容。

java 怎么取xss的request

alert('abc') 替换成alert('abc')这样的话显示出来也是alert('abc') 但是意义却不再是脚本而是字符串了。可以通过替换把这两个符号替换掉即可。

java怎么解决跨站脚本xss

跨站漏洞是需要其他正常用户进入到漏洞页面,执行了攻击者构造的恶意JS代码偷取cookie,假如攻击者获得高权限用户的cookie就有机会以高权限用户的身份进入系统,然后再进一步入侵。

所以治本的方法就是对攻击者提交的数据进行过滤,不给其执行的机会。
