篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了安全牛学习笔记中间人攻击ARP MITM中间人攻击Pass the Hash相关的知识，希望对你有一定的参考价值。
中间人攻击 Ettercap - 统一的中间人攻击工具 - 转发MAC与本机相同，但IP与本机不同的数据包 - 支持SSH1、SSL中间人攻击 模块划分 - Snifer - MITM - Filter - Log - Plugin |
中间人攻击 Snifer - 负责数据包转发 - Unified 单网卡情况下独立完成三层包转发 始终禁用内核IP_Forward功能 - Bridge 双网卡网卡的一层MITM模式 可作为IPS过滤数据包 不可在网卡上使用（透明网桥） MITM - 把流量重定向想到ettercap主机上 - 可以使用其他工具实现MITM，ettercap之作嗅探和过滤使用 |
中间人攻击 实现MITM的方法 - ARP - ICMP ICMP路由重定向，半双工 - DHCP 修改网关地址，半双工 - Switch Port Stealing flood目标地址是本机，源地址是受害者的包 适用于ARP静态绑定的环境 - NDP IPv6协议欺骗技术 |
中间人攻击 2.4以上内核对ARP地址欺骗的约束 - 收到非请求的ARP响应包，不更新本地ARP缓存 - Ettercap适用ARP request包进行攻击 Solaris不根据ARP包更新本地ARP缓存 - Ettercap使用先发ICMP包来更新ARP缓存 |
中间人攻击 用户操作界面 - -T 文本界面 - -G 图形界面 - -C 基于文本的图形界面 - -D 后台模式 指定目标 - IPv4 : MAC/IPs/Ports - IPv6 : MAC/IPs/IPv6/Ports - /10.0.0.1-5;10.0.1.33/20-25,80,110 |

#####################################
# you must provide a valid script for your operating system in order to have
# the SSL dissection available
# note that the cleanup script is executed without enough privileges (because
# they are dropped on startup). so you have to either: provide a setuid program
# or set the ec_uid to 0, in order to be sure the cleanup script will be
# executed properly
# NOTE: the script must fit into one line with a maximum of 255 characters
#---------------
# Linux
#---------------
# if you use ipchains:
#redir_command_on = "ipchains -A input -i %iface -p tcp -s 0/0 -d 0/0 %port -j REDIRECT %rport"
#redir_command_off = "ipchains -D input -i %iface -p tcp -s 0/0 -d 0/0 %port -j REDIRECT %rport"
# if you use iptables:
redir_command_on = "iptables -t nat -A PREROUTING -i %iface -p tcp --dport %port -j REDIRECT --to-port %rport"
redir_command_off = "iptables -t nat -D PREROUTING -i %iface -p tcp --dport %port -j REDIRECT --to-port %rport"
#---------------
# Mac Os X
#---------------
# quick and dirty way:
#redir_command_on = "ipfw -q add set %set fwd 127.0.0.1,%rport tcp from any to any %port in via %iface"
#redir_command_off = "ipfw -q delete set %set"
# a better solution is to use a script that keeps track of the rules interted
# and then deletes them on exit:
# redir_command_on:
# ----- cut here -------
# #!/bin/sh
# if [ -a "/tmp/osx_ipfw_rules" ]; then
# ipfw -q add `head -n 1 osx_ipfw_rules` fwd 127.0.0.1,$1 tcp from any to any $2 in via $3
# else
# ipfw add fwd 127.0.0.1,$1 tcp from any to any $2 in via $3 | cut -d " " -f 1 >> /tmp/osx_ipfw_rules
# fi
# ----- cut here -------
# redir_command_off:
# ----- cut here -------
# #!/bin/sh
# if [ -a "/tmp/osx_ipfw_rules" ]; then
# ipfw -q delete `head -n 1 /tmp/osx_ipfw_rules`
# rm -f /tmp/osx_ipfw_rules
# fi
# ----- cut here -------
#---------------
# FreeBSD
#---------------
# Before OF can be used, make sure the kernel module has been loaded by
# `kldstat | grep pf.ko`. If the rusult is empty, you can load it by
# `kldload pf.ko` or add ‘pf_enable="YES"‘ to the /etc/rc.conf and reboot.
# Check if the PF status is enabled by
# `pfctl -si | grep Status | awk ‘{print $2;}‘`. If "Disabled", enable it with
# `pfctl -e`.
#redir_command_on = "(pfctl -sn 2> /dev/null; echo ‘rdr pass on %iface inet proto tcp from any to any port %port -> localhost port %rport‘) | pfctl -f - 2> /dev/null"
#redir_command_off = "pfctl -Psn 2> /dev/null | grep -v %port | pfctl -f - 2> /dev/null"
#---------------
# Open BSD
#---------------
# unfortunately the pfctl command does not accepts direct rules adding
# you have to use a script which executed the following command:
# ----- cut here -------
# #!/bin/sh
# rdr pass on $1 inet proto tcp from any to any port $2 -> localhost port $3 | pfctl -a sslsniff -f -
# ----- cut here -------
# it‘s important to remember that you need "rdr-anchor sslsniff" in your
# pf.conf in the TRANSLATION section.
#redir_command_on = "the_script_described_above %iface %port %rport"
#redir_command_off = "pfctl -a sslsniff -Fn"
# also, if you create a group called "pfusers" and have EC_GID be that group,
# you can do something like:
# chgrp pfusers /dev/pf
# chmod g+rw /dev/pf
# such that all users in "pfusers" can run pfctl commands; thus allowing non-root
# execution of redir commands.

Security+认证为什么是互联网+时代最火爆的认证？
牛妹先给大家介绍一下Security+
Security+ 认证是一种中立第三方认证，其发证机构为美国计算机行业协会CompTIA ；是和CISSP、ITIL 等共同包含在内的国际 IT 业 10 大热门认证之一，和CISSP偏重信息安全管理相比，Security+ 认证更偏重信息安全技术和操作。
通过该认证证明了您具备网络安全，合规性和操作安全，威胁和漏洞，应用程序、数据和主机安全，访问控制和身份管理以及加密技术等方面的能力。因其考试难度不易，含金量较高，目前已被全球企业和安全专业人士所普遍采纳。
Security+认证如此火爆的原因？
原因一：在所有信息安全认证当中，偏重信息安全技术的认证是空白的， Security+认证正好可以弥补信息安全技术领域的空白 。
目前行业内受认可的信息安全认证主要有CISP和CISSP，但是无论CISP还是CISSP都是偏重信息安全管理的，技术知识讲的宽泛且浅显，考试都是一带而过。而且CISSP要求持证人员的信息安全工作经验都要5年以上，CISP也要求大专学历4年以上工作经验，这些要求无疑把有能力且上进的年轻人的持证之路堵住。在现实社会中，无论是找工作还是升职加薪，或是投标时候报人员，认证都是必不可少的，这给年轻人带来了很多不公平。而Security+的出现可以扫清这些年轻人职业发展中的障碍，由于Security+偏重信息安全技术，所以对工作经验没有特别的要求。只要你有IT相关背景，追求进步就可以学习和考试。
原因二： IT运维人员工作与翻身的利器。
在银行、证券、保险、信息通讯等行业，IT运维人员非常多，IT运维涉及的工作面也非常广。是一个集网络、系统、安全、应用架构、存储为一体的综合性技术岗。虽然没有程序猿们“生当做光棍，死亦写代码”的悲壮，但也有着“锄禾日当午，不如运维苦“的感慨。天天对着电脑和机器，时间长了难免有对于职业发展的迷茫和困惑。Security+国际认证的出现可以让有追求的IT运维人员学习网络安全知识，掌握网络安全实践。职业发展朝着网络安全的方向发展，解决国内信息安全人才的匮乏问题。另外，即使不转型，要做好运维工作，学习安全知识取得安全认证也是必不可少的。
原因三：接地气、国际范儿、考试方便、费用适中！
CompTIA作为全球ICT领域最具影响力的全球领先机构,在信息安全人才认证方面是专业、公平、公正的。Security+认证偏重操作且和一线工程师的日常工作息息相关。适合银行、证券、保险、互联网公司等IT相关人员学习。作为国际认证在全球147个国家受到广泛的认可。
在目前的信息安全大潮之下，人才是信息安全发展的关键。而目前国内的信息安全人才是非常匮乏的，相信Security+认证一定会成为最火爆的信息安全认证。
