最近在做系统安全基线检查相关的，网上找了一些脚本以及群友分享的。整理下分享给大家：

首先是Linux的shell加固脚本

#!/bin/bash
#设置密码复杂度if [ -z "`cat /etc/pam.d/system-auth | grep -v "^#" | grep "pam_cracklib.so"`" ];then  sed -i '/password    required      pam_deny.so/apassword    required      pam_cracklib.so  try_first_pass minlen=8 ucredit=-1   lcredit=-1   ocredit=-1 dcredit=-1 retry=3 difok=5' /etc/pam.d/system-authfi#密码输入失败3次，锁定5分钟sed -i 's#auth        required      pam_env.so#auth        required      pam_env.sonauth       required       pam_tally.so  onerr=fail deny=3 unlock_time=300nauth           required     /lib/security/$ISA/pam_tally.so onerr=fail deny=3 unlock_time=300#' /etc/pam.d/system-auth
#修改默认访问权限sed -i '/UMASK/s/077/027/' /etc/login.defs

#检查用户umask设置sed -i '/umask/s/002/077/' /etc/csh.cshrcsed -i '/umask/s/002/077/' /etc/bashrcsed -i '/umask/s/002/077/' /etc/profilecsh_login=`cat /etc/csh.login | grep -i "umask"`if [ -z "$csh_login" ];then  echo -e "/numask 077" >>/etc/csh.loginfi

#FTP安全设置 #如果安装了FTP服务 可以进行这个设置vsftpd_conf=`find /etc/ -maxdepth 2 -name vsftpd.conf`if [ ! -z "$vsftpd_conf" ];then  sed -i '/anonymous_enable/s/YES/NO/' $vsftpd_conffi
ftpuser=`find /etc/ -maxdepth 2 -name ftpusers`if [ ! -z "$ftpuser" ] && [ -z "`cat $ftpuser | grep -v "^#" | grep root`"];then  echo "root" >>$ftpuserfi
sed -i '/^ftp/d' /etc/passwd
#重要文件属性设置chattr +i /etc/passwdchattr +i /etc/shadowchattr +i /etc/groupchattr +i /etc/gshadowchattr +a /var/log/messages#chattr +i /var/log/messages.*
#检查core dump 设置chk_core=`grep core /etc/security/limits.conf | grep -v "^#"`if [ -z "$chk_core" ];then  echo "*               soft    core            0"  >> /etc/security/limits.conf  echo "*               hard    core            0"  >> /etc/security/limits.conffi
#删除潜在危险文件 可以先检查一下是否有危险文件，如果没有的话，就不需要执行这个hosts_equiv=`find / -maxdepth 3 -name hosts.equiv 2>/dev/null`if [ ! -z "$hosts_equiv" ];then  mv "$hosts_equiv" "$hosts_equiv".bakfi
_rhosts=`find / -maxdepth 3 -name .rhosts 2>/dev/null`if [ ! -z "$_rhosts" ];then  mv "$_rhosts" "$_rhosts".bakfi
_netrc=`find / -maxdepth 3 -name .netrc 2>/dev/null`if [ ! -z "$_netrc" ];then  mv "$_netrc" "$_netrc".bakfi
#检查系统内核参数配置,修改只当次生效，重启需重新设置sysctl -w net.ipv4.conf.all.accept_source_route="0"sysctl -w net.ipv4.conf.all.accept_redirects="0"sysctl -w net.ipv4.icmp_echo_ignore_broadcasts="1"sysctl -w net.ipv4.conf.all.send_redirects="0"sysctl -w net.ipv4.ip_forward="0"
#打开syncookie，缓解syn fiood攻击echo 1 > /proc/sys/net/ipv4/tcp_syncookies
#不响应ICMP请求echo 1 > /proc/sys/net/ipv4/icmp_echo_ignore_all
#防syn攻击优化，提高未连接队列大小sysctl -w net.ipv4.tcp_max_syn_backlog="2048"
#检查拥有suid和sgid权限文件并修改文件权限为755 目前这些不需要改变权限，需要定期巡检find /usr/bin/chage /usr/bin/gpasswd /usr/bin/wall /usr/bin/chfn /usr/bin/chsh /usr/bin/newgrp /usr/bin/write /usr/sbin/usernetctl /bin/mount /bin/umount /bin/ping /sbin/netreport -type f -perm /6000 | xargs chmod 755

然后是Windows的批处理脚本：（这里收集了两个，可根据自身情况修改整合）

1、一键加固
