New CISA guidance shows federal agencies how to use SASE to move from legacy TIC 2.0 to zero trust

生殖专家曾认为，女性绝经后，卵巢会像阑尾一样变得无用。在对 50-75 岁女性的卵巢进行检查时，研究人员发现该器官的细胞会随着年龄增长产生不同的蛋白质。为了更深入研究卵巢的年龄相关变化，研究人员转向了实验小鼠。尽管小鼠不会出现雌激素急剧下降等人类更年期特有特征，但这些动物在 2 年生命周期的后期，卵巢功能也会停止。研究人员分别从年轻小鼠、处于生殖期末期的小鼠以及“绝经”后小鼠体内摘取了卵巢。对每只动物，他们对其中一侧卵巢的 RNA 进行了测序，以测量基因表达情况。对另一侧卵巢，他们对组织进行了显微镜下视觉分析，以识别不同的细胞群，并测量纤维化的发展程度，纤维化是指随着年龄增长自然发生的硬化组织堆积现象。但对“绝经”后卵巢的分析显示，其中各类免疫细胞的水平均高于年轻小鼠的典型水平。此外，老年小鼠的卵巢中，编码各种促炎化合物的基因活性更高，这些免疫分子可能被分泌到血液中并随血液流向身体其他部位。尚不清楚衰老的卵巢究竟是真正发挥着免疫信号传导的作用，还是仅仅是免疫细胞的意外聚集地。这一发现或许有助于解释，为何女性尽管寿命更长，但随着年龄增长，健康状况往往不如男性。绝经后的卵巢可能会分泌某些分子，导致女性在更年期出现慢性炎症。

Despite the abundance of telemetry at analysts’ disposal, many security operations teams struggle to answer a few basic questions during incident investigation: What happened? What evidence do we have? How do we know we’re seeing it all, in context? Answering these questions requires teams to go beyond alerts, the most common basis for initial triage. But investigations (and their outcomes)

过去10年，很多行业人士来参加RC²的Level-2反窃密检测课程，所以杨叔也接触到很多从事（Executive Protection）即要人保护行业的公司、团队和个人，发现这个由退役特战、转业军警、安保、格斗教练、前情报人员甚至军迷混杂一起的行业里，参差不齐的水准确实让人一言难尽。 不过终于，EP行业刚刚迈出了历史性的关键一步。 要人保护专家委员会（BEPP）拥有了首个获得国家认可及 ANSI（美国国家标准学会）批准的《要人保护服务美国国家标准》（American National Standard for Providing Executive Protection）。 这份长达 550 多页的里程碑式标准，是历时近四年、投入数千工时，并汇集了 280 多位行业贡献者智慧的结晶；其制定过程严格遵循了 ANSI 的基本要求。它为全球保护行动确立了一个统一且可问责的基准，从而提升了专业水准与操作规程的行业标杆。 该标准出版物定价595美金，辅助书籍39.55美金。已开放预定，预计7月底发货：https://www.ep-board.org/store 其中， 《American National Standard for Providing Executive Protection》： 本标准为提供要人保护服务确立了全面的指导方针。其内容涵盖了支持要人保护行动的各项要素，包括但不限于威胁评估与风险缓解策略、保护小组的编队与行动规程、针对出行及各类活动的先遣工作程序，以及应对紧急情况的应急预案。标准强调了规划、专业素养、审慎行事以及持续培训对于要人保护人员的重要性。 《The Executive Protection Advance & Logistic Guidebook Version 2.0》则凝聚了业内多位资深从业者及BEPP成员在全球范围内管理与执行EP任务的丰富经验。 第2.0版新增内容有： 行动计划大纲 餐厅先遣勘察 航空器/船舶先遣勘察 先遣现场报告 快速先遣/非正式行程安排 要人保护组织架构与任务分工 新术语与定义 要人保护简报 哈哈，国内团队学习借鉴的时候到了～[机智][呲牙] 不管怎么说，就像BEPP 说的： It’s a dangerous world; be prepared. 世界充满风险，务必做好准备。
