Apache vs Nginx: Internal CA / PKI in Practice

Posted on 2026-01-122026-01-12 by Rico

When HTTPS Is About Identity Verification, Not Just Encryption After enterprises deploy an Internal CA / PKI, a common and dangerous situation often appears: “All our traffic is HTTPS, so we must be secure… right?” A closer inspection usually reveals uncomfortable truths: In Reverse Proxy + Internal PKI architectures,the difference between Apache and Nginx is…

Apache vs Nginx:Internal CA / PKI 實戰比較

Posted on 2026-01-122026-01-12 by Rico

當 HTTPS 不再只是「加密」,而是「信任驗證」 在企業內部導入 Internal CA / PKI 之後,很多團隊會遇到一個現實問題: 「我們明明全都走 HTTPS,為什麼安全性還是很模糊?」 深入一看才發現: 而在 Reverse Proxy + Internal CA 的實戰中,Apache 與 Nginx 在 PKI 行為上的差異,遠比效能差異重要。 這篇文章將從 企業實務角度,直接比較 Apache 與 Nginx 在 Internal CA / PKI 下的真實行為與風險。 一、Internal CA / PKI 在 Proxy 中到底在做什麼? 在 Reverse Proxy 架構下,Proxy 同時扮演兩個角色: 👉 PKI 真正發揮價值的地方,在「Proxy → Backend」這一段 二、架構示意(實戰情境) User│ HTTPS…

Reverse Proxy and Zero Trust Architecture

Posted on 2026-01-122026-01-12 by Rico

From Network Perimeters to Identity and Trust Enforcement Traditional enterprise security architectures were built on a simple assumption: Once you are inside the network, you are trusted. That assumption no longer holds true in modern environments where the following are now common: This is why Zero Trust is no longer a buzzword—it has become a…

Reverse Proxy 與 Zero Trust 架構

Posted on 2026-01-122026-01-12 by Rico

從「網路邊界防禦」走向「身分與信任驗證」 在傳統企業網路中,安全設計往往建立在一個假設上: 只要進了內網,就是可信的。 但在以下情境越來越普遍後,這個假設已經徹底失效: 這也是為什麼 Zero Trust(零信任) 不再只是口號,而是實際落地的架構方向。 而在 Zero Trust 架構中,Reverse Proxy 扮演的角色,比多數人想像中更關鍵。 一、什麼是 Zero Trust?(企業實務版) Zero Trust 的核心精神可以用一句話總結: Never trust, always verify不因為位置而信任,只因「驗證結果」而授權。 Zero Trust 不等於 ❌ 一定要上雲❌ 一定要買昂貴設備❌ 一次性大改架構 Zero Trust 真正關心的是 二、Reverse Proxy 在 Zero Trust 中的定位 傳統架構 問題: Zero Trust 架構(Reverse Proxy 為核心) 👉 Reverse Proxy 成為真正的「信任閘門」 三、Reverse Proxy 為什麼適合 Zero…

企業 Internal PKI 架構實戰

Posted on 2026-01-122026-01-12 by Rico

從「能簽憑證」到「可長期營運的信任系統」 在很多企業裡,「Internal PKI」的現況往往是: 結果就是: PKI 變成一顆不敢碰的地雷,而不是企業的安全基石。 這篇文章不談理論、不談名詞,專注在一件事: 企業要如何真正「落地」一套可維運、可控、可交接的 Internal PKI 架構。 一、企業 Internal PKI 的實際目標是什麼? 在實務中,Internal PKI 的目標從來不是「跟公開 CA 一樣完整」,而是: 👉 重點是「可營運」,不是「技術炫技」。 二、實戰架構總覽(企業等級) 核心原則 三、Root CA:企業最重要、也最容易做錯的角色 Root CA 的正確定位 Root CA 實戰做法 Root CA 的存在,是為了「最壞情況還能活下來」。 四、Intermediate CA:企業 PKI 的核心戰場 為什麼企業一定要有 Intermediate? 因為企業一定會遇到: 👉 Intermediate CA 可以撤銷,Root CA 不行。 Intermediate CA 實戰建議 五、憑證分類策略(企業一定要做) ❌ 常見錯誤 ✅…

企業自建 CA 的最佳實務

Posted on 2026-01-122026-01-12 by Rico

在企業 IT 架構中,隨著以下需求越來越普遍: 自建 CA(Internal Certificate Authority) 幾乎已成為中大型企業的標準配置。 但實務上,很多企業的自建 CA: 這篇文章將從 企業等級的角度,說明「自建 CA 該怎麼做,才不會變成資安地雷」。 一、什麼情況下「一定要」自建 CA? 企業選擇自建 CA,通常不是為了取代公開 CA(如 Let’s Encrypt),而是為了解決 內部信任問題。 常見適用場景 👉 只要憑證不會被公開瀏覽器使用,自建 CA 就是合理選擇。 二、企業自建 CA 的基本架構(強烈建議) 正確的 CA 架構:兩層式(至少) 為什麼不能只用一層? 三、Root CA 的最佳實務(最重要) ✅ Root CA 必須 Offline ✅ Root CA 金鑰保護 ✅ Root CA 有效期限 四、Intermediate CA 的最佳實務(實際運作核心) Intermediate CA…
