ATT&CK模型 ATT&CK是分析攻击者行为（即TTPs）的 威胁分析框架 。ATT&CK框架核心就是以矩阵形式展现的TTPs，即Tactics, Techniques and Procedures（战术、技术及步骤），是指攻击者从踩点到获取数据以及这一过程中的每一步是“如何”完成任务的。 ATT&CK模型分为三部分，分别是 PRE-ATT&CK ， ATT&CK for Enterprise 和 ATT&CK for Mobile。 目前只学习 ATT&CK for Enterprise部分。 ATT＆CK导航器 https://mitre-attack.github.io/attack-navigator/enterpris 其中，该框架囊括12类战术。 Initial Access 初始访问 Execution 执行 Persistence 持久化 Privilege Escalation 权限提升 Defense Evasion 防御逃逸 Credential Access 凭证获取 Discovery 发现 Lateral Movement 横向移动 Collection 收集 Command and Control 命令与控制 Exfiltration 数据渗出 Impact 影响 除了12种战术，还包括244种在相应战术中应用的具体技术

2. Related Work 关于细粒度图像识别的研究沿着两个维度进行，即 判别性特征学习和复杂的局部定位 。 2.1. Discriminative Feature Learning 学习判别性特征对于细粒度图像识别至关重要。由于深度学习的成功，大多数方法依赖于强大的卷积深层特征， 其在通用 和细粒度识别上 比手工制作的特征有着显着改善[4,5,6,17,29]。为了学习更强大的特征表示，深度残差网络[9]通过优化残差函数将CNN加深到152层，其将ImageNet测试集中的错误率降低到3.75％[17]。为了更好地建模细粒度类别中存在的微妙差异，最近提出一种双线性结构[ 19 ]来计算两个独立CNN的成对特征的相互作用来捕获图像的局部差异，这已经取得了鸟类分类中最先进的成果[30]。此外，另一种方法[ 34 ]提出用Fisher Vector[23]统一CNN与空间加权表示，显示了在鸟[30]和狗数据集[13]的优异结果。 2.2. Sophisticated Part Localization 以前的工作主要集中在利用边界框和部分注释等额外注释来定位细粒度识别中的重要区域[10，18，22，30，32，33]。然而，手动注释的大量劳动使得此任务对于大规模的实际问题不可行。最近，出现了一些新的工作，旨在提出一个更一般的情况，并提出使用无监督的方法来挖掘注意力区域

IOC Security: Indicators of Attack vs. Indicators of Compromise https://www.crowdstrike.com/blog/indicators-attack-vs-indicators-compromise/ December 9, 2014 Jessica DeCianno Endpoint Protection What is an Indicator of Compromise (IOC)? First we should provide a definition of an indicator of compromise (IOC). An IOC is often described in the forensics world as evidence on a computer that indicates that the security of the network has been breached. Investigators usually gather this data after being informed of a suspicious incident, on a scheduled basis, or after the discovery of unusual call
