Gmail 要開始導入 SMTP Strict Transport Security 了

SMTP MTA Strict Transport Security 算是 SMTP STARTTLS 裡的 HSTS 機制,而 Google 的人在 RSA Conference 上提出要開始用了:「SMTP STS Coming Soon to Gmail, Other Webmail Providers」。

Elie Bursztein, the head of Google’s anti-abuse research team, said at RSA Conference that SMTP STS will be a major impediment to man-in-the-middle attacks that rely on rogue certificates that are likely forged, stolen or otherwise untrusted. Google, Microsoft, Yahoo and Comcast are expected to adopt the standard this year, a draft of which was submitted to the IETF in March 2016.

補上去後對於 SMTP 的隱私保護就會更好了...

RSA Conference 2015 禁止 Show Girl

前幾天的消息:「RSA Conference Bans "Booth Babes"」。報導出自於「RSA Conference bans ‘booth babes’」。


All Expo staff are expected to dress in business and/or business casual attire. Exhibitors should ensure that the attire of al staff they deploy at their booth (whether the exhibitor’s direct employees or their contractors) be considered appropriate in a professional environment. Attire of an overly revealing or suggestive nature is not permitted. Examples of such attire may include but are not restricted to:

  • Tops displaying excessive cleavage;
  • Tank tops, halter tops, camisole tops or tube tops;
  • Miniskirts or minidresses;
  • Shorts;
  • Lycra (or other Second-Skin) bodysuits;
  • Objectionable or offensive costumes.

These guidelines are applicable to all booth staff, regardless of gender, and will be strictly enforced. We reserve the right to request that individual booth staff change their attire or leave the premises immediately if we feel their appearance might be offensive to other exhibitors or attendees.

讓我想起 2009 年 Yahoo! 辦的 Taiwan Open Hack Day:「Yahoo Sorry About Lap Dancers at Hack Day in Taiwan–So What's the Excuse for Last Year's Go-Go Girls?」。

OWASP 取消與 RSA Conference 的合作...

RSA Security 收了 NSA 的錢,並且使用 NSA 所偏好的亂數演算法的事情被爆料出來後 (而且這個演算法已經被認為是 NSA 埋後門的演算法),一直有要求 RSA Security 解釋的聲音。但 RSA Security 卻完全沒有解釋。

想當然的,陸陸續續開始有人退出今年的 RSA Conference。一開始是 F-Secure 的 CRO (Chief Research Officer) 宣布退出:「An Open Letter to the Chiefs of EMC and RSA」,後來也有不少資安領域的專家退出 (可以參考 iThome 的文章):「資安專家群起抵制RSA安全會議」。

最新的消息是 OWASP 官方決定取消與 RSA Conference 的合作關係:「OWASP terminates marketing agreement with RSA Conference. Board member cancels class out of protest.」,不過 OWASP 正式的公告還沒出來。

OWASP 在 Web 安全性這個領域可是赫赫有名... 這下今年二月底的 RSA Conference 還會有多少人「跟進」呢... 會不會停辦?

香港開源年會 2013


香港開源年會 2013」(第一屆!) 將於 10 月 19 日在香港城市大學邵逸夫創意媒體中心舉辦,現在訂機票有點晚,不過還是可以過去交流...

其實有些議程還蠻有興趣去交流的,不過剛好卡到員工旅遊啊... @_@

該來找日本的 conference 了?@_@



這次是 BruCON 2013 的記錄,有兩篇:「BruCON 0×05 Wrap Up」、「What Do Attendees During a Security Conference?」。

第一篇首先是依照 OS 數量的分析:


另外發現有大量的 OpenVPN 以及 IPsec 封包,這也的確是資安研討會應該要出現的東西... XD

第二篇的分析也很有趣,像是對 DNS 的分析:

大紅點是官方提供的 DNS (,兩個小紅點是 Google 提供的 DNS 服務 ( 與,而黃點則是 mDNS

然後官方有提供兩包 50GB 的檔案... 要分析的人也可以拿去玩 XD

然後提到 The Bro Network Security Monitor,找機會玩看看好了...
