# TaiwanHolyHigh - Windows Forensics - Background [TOC] ## Background ### ==資安事件的流程==  * Prepare * 建立Infra * 購買ISO(e.g. [ISO 27001](https://www.tsg.com.tw/blog-detail10-248-0-iso27001.htm)) * SPA([資安健診](https://www.issdu.com.tw/service/9-shc)) * Predict * [Threat Intelligence(威脅情資)](https://www.informationsecurity.com.tw/article/article_detail.aspx?aid=8376) * Recon(情蒐) * Monitor(監控) * 搜尋Pattern * Identify(識別): 有興趣可以看這一篇論文筆記[DeepCase](https://hackmd.io/@SBK6401/BJuCGSnAo) * [SOC(資安監控中心)](https://www.freedom.net.tw/ict-insight/security/siem-vs-soc.html) >  * IDS: 入侵偵測系統(Intrusion Detection System,IDS)是用來偵測資訊系統或網路上潛在的惡意破壞活動 * IPS: [IThelp - Active Defense](https://www.ithome.com.tw/tech/28712) * Audit: AD常常遇到 * EDR * Code Review * Prevent: 防禦攻擊 * Firewall(Layer 4 - Transport) * [WAF(Layer 7 - Application)](https://www.oracle.com/tw/security/cloud-security/what-is-waf/) * [DLP(資料外洩防護)](https://www.mikotek.com.tw/dlp/) * Incident Profile: 這個項目比較能夠得到一些惡意的行為,而該行為一定脫離不了下面三點 1. Purpose/Payload(有可能是Data, Source, 或金錢等等) 2. Path(透過甚麼途徑達成目的,有可能是USB, 社交工程, 0-day) 3. Behavior(建立帳戶/開service/與C&C連線等等) * Incident Response * Restore(主動) * Recovery(被動) * Isolate * Deter: 主動式的阻絕 * Inside * Outside(就是找外援通常是執法單位) * law enforcement(執法單位) * Forensics Triage: 做分流的動作 * 揮發性資料(RAM...) * Network * Process * System * Artifacts(registry/log/temp...) * Duplicate(Image): 製作證據的映像檔$\to$非揮發性的資料 * RAW Image * Evidence File * Forensics Analysis * 已知項目(Known) * Keyword * Hash * Baseline * Recovery * Signature * Sorting * Artifact * LNK * Prefetch * SPL * Thumbnail * Registry(非揮發性) * Log * Recycle Bin ### ==網路攻擊鍊(Cyber Kill Chain)== 詳細資料: [TeamT5 - Cyber Kill Chain](https://teamt5.org/tw/posts/what-is-cyber-kill-chain/) 1. 偵查 Reconnaissance 2. 武裝 Weaponization 3. 遞送 Delivery 4. 漏洞利用 Exploitation: 確保遞送的惡意軟體,藉由目標對象的系統漏洞,得以順利開啟,並使攻擊者獲得控制權 5. 安裝 Installation 6. 發令與控制 Command & Control 7. 行動 Actions
