红蓝对抗——蓝队手册

0x01 前言

红蓝对抗的思想最早可追溯到我国现存最早的一部兵书《孙子兵法》，在孙子·谋攻篇有这么一句话：“知彼知己，百战不殆；”，意为如果对敌我双方的情况都能了解透彻，打多少次仗都不会失败。在信息安全领域目前大家都有一个共识：“未知攻，焉知防”，攻防对抗本身是一个持续的过程，在具体的对抗中，对对手了解越多就会占据主导地位。

红蓝对抗的主要目的在于，提高公司安全成熟度及其检测和响应攻击的能力。

Red Teams attack, and Blue Teams defend, but the primary goal is shared between them: improve the security posture of the organization.
