Kernel rootkit通过修改控制数据或者内核中的钩子而劫持控制流，从而隐藏自己的存在。因此保护这些钩子函数成为一个关键问题（引出出问题了）。但是有许多从内核堆中动态分配的钩子，并且与其它内核数据混在一起，这造成了很多难度。另外，缺少灵活的商业硬件支持，造成了所谓的保护粒度沟（内核钩子的保护要求byte级别的粒度，但是商业硬件只支持页级别的保护）。
为解决这些问题，本文提出了HookSafe的概念，基于hypervisor的轻量级的系统，可以保护guestOS中]]>https://blog.youkuaiyun.com/sploving/article/details/6035457https://blog.youkuaiyun.com/sploving/article/details/6035457splovingThu, 25 Nov 2010 17:20:00 +0800https://blog.youkuaiyun.com/sploving/article/details/6030300https://blog.youkuaiyun.com/sploving/article/details/6030300splovingTue, 23 Nov 2010 17:34:00 +0800 

漫长而黑暗的史前时代终于到了setup。在setup汇编函数中，linux通过设置cr0寄存器的PE位（从实模式切换到保护模式）完成了史前文明到现代文明的转变。在setup时期，linux已经了解到世上可用的内存资源远远不止1MB。此时linux的欲望开始膨胀，最为满足它欲望的第一步，它开始抢占内存资源的前8MB。 初始化临时内核页表是在startup_32汇编语言函数中完成的。在ULK所述中，假设内核能容纳于RAM的前8MB空间，然后对RAM的前8MB进行恒等映]]>https://blog.youkuaiyun.com/sploving/article/details/5990507https://blog.youkuaiyun.com/sploving/article/details/5990507splovingFri, 05 Nov 2010 18:31:00 +0800https://blog.youkuaiyun.com/sploving/article/details/5967514https://blog.youkuaiyun.com/sploving/article/details/5967514splovingTue, 26 Oct 2010 19:30:00 +0800 yum install kdebase-devel

放到了/home/sploving/application目录下
1. 首先创建一个虚拟硬盘来安装hvm
mkdir hvm
dd if=/dev/zero of=/hvm/ubuntu.img bs=1k seek=10000k count=1
2. 创建配置文件]]>https://blog.youkuaiyun.com/sploving/article/details/5914290https://blog.youkuaiyun.com/sploving/article/details/5914290splovingWed, 29 Sep 2010 14:50:00 +0800https://blog.youkuaiyun.com/sploving/article/details/5866363https://blog.youkuaiyun.com/sploving/article/details/5866363splovingMon, 06 Sep 2010 15:12:00 +0800https://blog.youkuaiyun.com/sploving/article/details/5862273https://blog.youkuaiyun.com/sploving/article/details/5862273splovingFri, 03 Sep 2010 21:25:00 +08001.下载xen4.01的源码

make menuconfig
把CONFIG_IMA*选上
然后make -j4;make install, make modules, make modules_install
即可
在启动时，grub的kernel那一项要加上
ima_tcb=1
这样就可以查看/sys/kernel/security/ima/里面的东西了]]>https://blog.youkuaiyun.com/sploving/article/details/5855823https://blog.youkuaiyun.com/sploving/article/details/5855823splovingWed, 01 Sep 2010 15:53:00 +0800当用到ltp进行测试时，下载源码
./configure
./make && make install
当进行测试时
./runltp -f ima总是出现下面错误：
