Centos5/Centos6服务器安装SSH蜜罐Kippo
发布时间:May 28, 2012 // 分类:网络安全 // No Comments
Kippo是一个虚拟的交互式的SSH环境模拟,以Python 语言编写,攻击者连接ssh时会被欺骗到蜜罐中,攻击者的口令
猜测记录、执行命令、下载文件和IP地址都会被记录下来。
安装要求:
# Python 2.5+
# Twisted 8.0+
# PyCrypto
# Zope Interface
yum安装Python26,rpm安装请参考:http://www.geekymedia.com/tech-articles/rhel5-centos5-rpms-for-python-2-5-and-2-6/
yum -y install python26 python26-devel
安装Twisted:
cd /usr/local/src/
wget http://twistedmatrix.com/Releases/Twisted/10.2/Twisted-10.2.0.tar.bz2
tar -xvf Twisted-10.2.0.tar.bz2
cd Twisted-10.2.0
python26 setup.py build
python26 setup.py install
cd ../
安装zope:
wget http://www.zope.org/Products/ZopeInterface/3.3.0/zope.interface-3.3.0.tar.gz
tar -xvf zope.interface-3.3.0.tar.gz
cd zope.interface-3.3.0
python26 setup.py build
python26 setup.py install
cd ../
安装pycrypto:
wget https://ftp.dlitz.net/pub/dlitz/crypto/pycrypto/pycrypto-2.0.1.tar.gz
tar zxvf pycrypto-2.0.1.tar.gz
cd pycrypto-2.0.1
python26 setup.py build
python26 setup.py install
cd ../
安装pyasn1:
wget http://sourceforge.net/projects/pyasn1/files/pyasn1/0.0.13/pyasn1-0.0.13.tar.gz
tar zxvf pyasn1-0.0.13.tar.gz
cd pyasn1-0.0.13
python26 setup.py build
python26 setup.py install
cd ../
Centos6安装以上环境比较简单:
yum install twisted python-zope-interface python-pyasn1
Kippo安装,以非root用户运行:
useradd kippo
su -l kippo
wget http://kippo.googlecode.com/files/kippo-0.5.tar.gz
tar zxvf kippo-0.5.tar.gz
cd kippo-0.5
./start.sh
kippo默认监听2222端口,可以更改ssh端口为非22,利用iptables重定向端口2222到22:
iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 22 -j REDIRECT --to-port 2222
kippo配置文件:
kippo.cfg
登录及命令记录日志:
kippo.log
Mysql基本安全设置
发布时间:May 27, 2012 // 分类:数据库 // No Comments
1.设置或修改Mysql root密码:
默认安装后空密码,以mysqladmin命令设置密码:
mysqladmin -uroot password "password"
Mysql命令设置密码:
mysql> set password for root@localhost=password('password);
更改密码:
update mysql.user set password=password('password') where user='root';
flush privileges;
2.删除默认的数据库和用户
drop database test;
use mysql;
delete from db;
delete from user where not(host="localhost" and user="root");
flush privileges;
更改默认root账号名称:
update mysql.user set user="admin" where user="root"; flush privileges;
本地文件安全:
set-variable=local-infile=0
禁止远程连接mysql,远程管理可通过phpmyadmin,编辑my.cnf在[mysqld]添加:
skip-networking
6.最小权限用户:
#CREATE USER 'user'@'localhost' IDENTIFIED BY 'password'; GRANT USAGE ON *.* TO 'user'@'localhost' IDENTIFIED BY PASSWORD '*2470C0C06DEE42FD1618BB99005ADCA2EC9D1E19'; GRANT SELECT, INSERT, UPDATE, DELETE, CREATE ON `databases`.* TO 'user'@'localhost';
限制普通用户浏览其它数据库,编辑my.cnf在[mysqld]添加:
--skip-show-database
8.快速修复MySQL数据库
修复数据库mysqlcheck -A -o -r -p
修复指定的数据库
mysqlcheck -o -r database -p
9.跟据内存的大小选择MySQL的配置文件:
my-small.cnf # > my-medium.cnf # 32M - 64M my-large.cnf # memory = 512M my-huge.cnf # 1G-2G my-innodb-heavy-4G.cnf # 4GB

Windows 2003 IIS6安装配置PHP环境
发布时间:May 27, 2012 // 分类:IIS // No Comments
本文以PHP线程安全版安装为例,下载PHP:http://windows.php.net/downloads/releases/php-5.2.17-Win32-VC6-x86.zip
进入解压目录,复制libmysql.dll至c:\windows\system32目录下,如需开启mcrypt扩展,也要复制libmcrypt.dll至此目录。
修改配置php.ini-recommended为php.ini并复制到c:\windows目录下。.
#https://www.haiyun.me
extension_dir = "c:\php\ext"
cgi.force_redirect = 0
cgi.fix_pathinfo=1
fastcgi.impersonate = 1
extension=php_gd2.dll
extension=php_mbstring.dll
extension=php_gettext.dll
extension=php_mcrypt.dll
extension=php_mhash.dll
extension=php_mime_magic.dll
extension=php_mysql.dll
extension=php_mysqli.dll
extension=php_xmlrpc.dll
extension=php_zip.dll
配置IIS6支持PHP:
网站——右键——属性——主目录——配置——添加:
添加文档index.php:
添加Web扩展:
重启启动IIS生效,新建phpinfo测试:
<?php
phpinfo();
?>
修改php.ini配置文件需重启IIS生效
PHP安装目录需IIS_WPG用户与IUSER用户的访问权
PHP的session 目录和 log 目录,至少需要IIS_WPG用户与IUSER用户的写入权。
PHP程序如果有 include 命令,若要正常运行,至少需要文件所在的上级目录上有ISUER访问权。
如果安装ZendOptimizer,那ZendOptimizer至少需要NETWORKS SERVICE组的访问权
