HTTPS Everywhere 改變更新 Ruleset 機制,變成定時更新...

HTTPS Everywhere 是我很喜歡的一個套件,裡面有 Ruleset,會將 Ruleset 表內認定有支援 HTTPS 網站的 HTTP request 都改成 HTTPS,這可以降低被攔截的風險。像是網站雖然有 HSTS 但第一次連線時走 HTTP 的情況,以及網站本身有支援 HTTPS 但沒有設定 HSTS 時,在網址列上誤打 HTTP 版本的情況。

先前版本的 Ruleset 是隨著軟體更新時,包在軟體內一起更新。這樣的缺點是更新速度比較慢,但好處是不需要伺服器端,而且隱私性也比較高。而現在 EFF 決定還是要推出線上更新的版本,以加速 Ruleset 更新的速度:「HTTPS Everywhere Introduces New Feature: Continual Ruleset Updates」。

We've modified the extension to periodically check in with EFF to see if a new list is available.

而頻寬的部份由 Fastly 贊助:

If you haven't already, please install and contribute to HTTPS Everywhere, and consider donating to EFF to support our work!

如果對這點有疑慮的,也還是可以關掉 auto updater 避免洩漏資訊給 EFF 或是 Fastly。

AWS WAF 提供隨時更新的 Managed Rules

AWS WAF 推出了隨時更新的 Managed Rule:「Ready-to-Use Managed Rules Now Available on AWS WAF」。

這些 ruleset 是由 3rd-party 提供的:

Choose from preconfigured RuleGroups provided in the AWS Marketplace by industry leading security experts: Alert Logic, Fortinet, Imperva, Trend Micro and TrustWave.

然後隨時更新:

Rules are automatically updated as new threats emerge and offer a wide range of protections, including OWASP Top 10 mitigations, bad-bot defenses, and virtual patching against recent CVE’s.

然後是要收費的:

Each RuleGroup is the product of a Seller’s unique expertise, made available to you at an affordable pay-as-you-go price.
