أمن طبقة النقل

أمن طبقة النقل Transport Layer Security (TLS) ، وسابقته طبقة المنافذ الآمنة Secure Sockets Layer (SSL)، هي پروتوكولات تعمية مصممة للحصول على أمن الاتصالات في شبكات الحاسوب. هناك إصدارات مختلفة للپروتوكولات تستخدم على نطاق واسع في تطبيقات مثل تصفح الإنترنت، البريد الإلكتروني، فاكس الإنترنت، التراسل الفوري، والصوت عبر الإنترنت. مواقع الوب الرئيسية (تضم گوگل، يوتيوب، فيسبوك وغيرها) تستخدم أمن طبقة النقل لتأمين جميع الاتصالات بين خوادمها ومتصفحات الوب.

الوصف

إن معظم إجراءات البروتوكول تُنفّذ حال البدء بتبادل المعلومات وطلب إعداد قناة اتصال آمنة، حيث يبدأ البروتوكول العمل عندما يقوم حاسب المستخدم بطلب الوثوقية من المخدم. يحدد الطلب الذي يقوم به المستخدم وهوخوارزمية التشفير التي يمكن استخدامها بالإضافة إلى نص التحدي. (نص التحدي باختصار هومادة عشوائية يتم ارجاعها ضمن محتوى مشفر لمنع إعادة إرسال تلك النصوص المشفرة والتي كانت تستخدم في السابق، مما يعني حتى نص التحدي مختلفاً عن النصوص المشفرة).

أما التوثيق الذي يقوم المخدم بإعادته فيكون على شكل شهادة تحوي توقيع مفتاح المخدم المعلن، وعلى أفضليات المخدم لخوارزمية التشفير التي ستستخدم. يقوم حاسب المستخدم بعد ذلك بإنشاء مفتاح أصلي، وتشفير مفتاح المخدم، ومن ثم يقوم بإرسال النتيجة إلى المخدم. حينذاك، يقوم المخدم بإعادة الرسالة المشفرة مع المفتاح الأصلي، حيث يستخدم هذا المفتاح لإنشاء المفاتيح اللازمة لإرسال الرسائل.

التطبيقات والاستخدامات

يستطيع بروتوكول SSL تشفير كافة الاتصالات بين المنافذ فوراً وبدون تدخل من المستخدم، الأمر الذي يوفر الدعم الأمني لكافة تطبيقات الانترنيت، وخاصة البريد الإلكتروني، وبروتوكول تل نت، وبروتوكول نقل الملفات، بالإضافة إلى مختلف التبادلات التي تتم على الويب، حيث يمكن حمايتها كافة عن طريق SSL.

Notes

^ Does the browser have mitigations or is not vulnerable for the known attacks. Note actual security depends on other factors such as negotiated cipher, encryption strength etc (see #Cipher table).
^ Whether a user or administrator can choose the protocols to be used or not. If yes, several attacks such as BEAST (vulnerable in SSL 3.0 and TLS 1.0) or POODLE (vulnerable in SSL 3.0) can be avoided.
^ Whether EV SSL and DV SSL (normal SSL) can be distinguished by indicators (green lock icon, green address bar, etc.) or not.
^ e.g. 1/n-1 record splitting.
^ e.g. Disabling header compression in HTTPS/SPDY.
^
- Complete mitigations; disabling SSL 3.0 itself, "anti-POODLE record splitting". "Anti-POODLE record splitting" is effective only with client-side implementation and valid according to the SSL 3.0 specification, however, it may also cause compatibility issues due to problems in server-side implementations.
- Partial mitigations; disabling fallback to SSL 3.0, TLS_FALLBACK_SCSV, disabling cipher suites with CBC mode of operation. If the server also supports TLS_FALLBACK_SCSV, the POODLE attack will fail against this combination of server and browser, but connections where the server does not support TLS_FALLBACK_SCSV and does support SSL 3.0 will still be vulnerable. If disabling cipher suites with CBC mode of operation in SSL 3.0, only cipher suites with RC4 are available, RC4 attacks become easier.
- When disabling SSL 3.0 manually, POODLE attack will fail.
^
- Complete mitigation; disabling cipher suites with RC4.
- Partial mitigations to keeping compatibility with old systems; setting the priority of RC4 to lower.
^ Google Chrome (and Chromium) supports TLS 1.0, and TLS 1.1 from version 22 (it was added, then dropped from version 21). TLS 1.2 support has been added, then dropped from Chrome 29.
^ Uses the TLS implementation provided by BoringSSL for Android, OS X, and Windows or by NSS for Linux. Google is switching the TLS library used in Chrome to BoringSSL from NSS completely.
^ configure enabling/disabling of each protocols via setting/option (menu name is dependent on browsers)
^ configure the maximum and the minimum version of enabling protocols with command-line option
^ TLS_FALLBACK_SCSV is implemented. Fallback to SSL 3.0 is disabled since version 39.
^ In addition to TLS_FALLBACK_SCSV and disabling a fallback to SSL 3.0, SSL 3.0 itself is disabled by default.
^ configure the minimum version of enabling protocols via chrome://flags (the maximum version can be configured with command-line option)
^ Only when no cipher suites with other than RC4 is available, cipher suites with RC4 will be used as a fallback.
^ Uses the TLS implementation provided by NSS. As of Firefox 22, Firefox supports only TLS 1.0 despite the bundled NSS supporting TLS 1.1. Since Firefox 23, TLS 1.1 can be enabled, but was not enabled by default due to issues. Firefox 24 has TLS 1.2 support disabled by default. TLS 1.1 and TLS 1.2 have been enabled by default in Firefox 27 release.
^ configure the maximum and the minimum version of enabling protocols via about:config or add-on
^ SSL 3.0 itself is disabled by default. In addition, fallback to SSL 3.0 is disabled since version 34, and TLS_FALLBACK_SCSV is implemented since 35.0 and ESR 31.3.
^ All RC4 cipher-suites is disabled by default.
^ IE uses the TLS implementation of the Microsoft Windows operating system provided by the SChannel security support provider. TLS 1.1 and 1.2 are disabled by default until IE11.
^ Windows NT 3.1 supports IE 1–2, Windows NT 3.5 supports IE 1–3, Windows NT 3.51 and Windows NT 4.0 supports IE 1–6
^ Windows XP as well as Server 2003 and older only support weak ciphers like 3DES and RC4. The weak ciphers of these SChannel version are not only used for IE. They are also used for other Microsoft products running on this OS, e.g like Office. Only Windows Server 2003 can get a manually update to support AES ciphers by KB948963
^ MS13-095 or MS14-049 for 2003 and XP-64 or SP3 for XP (32-bit)
^ Internet Explorer Support Announcement
^ RC4 can be disabled except as a fallback (Only when no cipher suites with other than RC4 is available, cipher suites with RC4 will be used as a fallback.)
^ Fallback to SSL 3.0 is sites blocked by default in Internet Explorer 11 for Protected Mode. SSL 3.0 is disabled by default in Internet Explorer 11 since April 2015.
^ Edge (formerly known as Project Spartan) is based on a fork of the Internet Explorer 11 rendering engine.
^ Except Windowsعشرة LTSB 2015 (LongTermSupportBranch)
^ Could be disabled via registry editing but need 3rd Party tools to do this.
^ Operaعشرة added support for TLS 1.2 as of Presto 2.2. Previous support was for TLS 1.0 and 1.1. TLS 1.1 and 1.2 are disabled by default (except for versionتسعة that enabled TLS 1.1 by default).
^ SSL 3.0 is disabled by default remotely since October 15, 2014
^ TLS support of Opera 14 and above is same as that of Chrome, because Opera has migrated to Chromium backend (Opera 14 for Android is based on Chromium 26 with WebKit, and Opera 15 and above are based on Chromium 28 and above with Blink).
^ TLS_FALLBACK_SCSV is implemented.
^ SSL 3.0 is enabled by default, with some mitigations against known vulnerabilities such as BEAST and POODLE implemented.
^ In addition to TLS_FALLBACK_SCSV, "anti-POODLE record splitting" is implemented.
^ In addition to TLS_FALLBACK_SCSV and "anti-POODLE record splitting", SSL 3.0 itself is disabled by default.
^ configure the minimum version of enabling protocols via opera://flags (the maximum version can be configured with command-line option)
^ Safari uses the operating system implementation on Mac OS X, Windows (XP, Vista, 7) with unknown version, Safariخمسة is the last version available for Windows. OS X 10.8 on have SecureTransport support for TLS 1.1 and 1.2 Qualys SSL report simulates Safari 5.1.9 connecting with TLS 1.0 not 1.1 or 1.2
^ In September 2013, Apple implemented BEAST mitigation in OS X 10.8 (Mountain Lion), but it was not turned on by default resulting in Safari still being theoretically vulnerable to the BEAST attack on that platform. BEAST mitigation has been enabled by default from OS X 10.8.5 updated in February 2014.
^ Because Apple removed support for all CBC protocols in SSL 3.0 to mitigate POODLE, this leaves only RC4 which is also completely broken by the RC4 attacks in SSL 3.0.
^ Mobile Safari and third-party software utilizing the system UIWebView library use the iOS operating system implementation, which supports TLS 1.2 as of iOS 5.0.

[ciphers-5] see #Cipher table below

[mitigations-6] see #Web browsers and #Attacks against TLS/SSL sections

[note-sec-7] Does the browser have mitigations or is not vulnerable for the known attacks. Note actual security depends on other factors such as negotiated cipher, encryption strength etc (see #Cipher table).

[note-poodle-8] Whether a user or administrator can choose the protocols to be used or not. If yes, several attacks such as BEAST (vulnerable in SSL 3.0 and TLS 1.0) or POODLE (vulnerable in SSL 3.0) can be avoided.

[note-evssl-9] Whether EV SSL and DV SSL (normal SSL) can be distinguished by indicators (green lock icon, green address bar, etc.) or not.

[note-BEASTmitigation-13] .g. 1/n-1 record splitting.

[note-CRIMEmitigation-14] .g. Disabling header compression in HTTPS/SPDY.

[note-POODLEmitigation-15] 

Complete mitigations; disabling SSL 3.0 itself, "anti-POODLE record splitting". "Anti-POODLE record splitting" is effective only with client-side implementation and valid according to the SSL 3.0 specification, however, it may also cause compatibility issues due to problems in server-side implementations.

Partial mitigations; disabling fallback to SSL 3.0, TLS_FALLBACK_SCSV, disabling cipher suites with CBC mode of operation. If the server also supports TLS_FALLBACK_SCSV, the POODLE attack will fail against this combination of server and browser, but connections where the server does not support TLS_FALLBACK_SCSV and does support SSL 3.0 will still be vulnerable. If disabling cipher suites with CBC mode of operation in SSL 3.0, only cipher suites with RC4 are available, RC4 attacks become easier.

When disabling SSL 3.0 manually, POODLE attack will fail.

[9] Complete mitigations; disabling SSL 3.0 itself, "anti-POODLE record splitting". "Anti-POODLE record splitting" is effective only with client-side implementation and valid according to the SSL 3.0 specification, however, it may also cause compatibility issues due to problems in server-side implementations.

[Fx-POODLE-67] SSL 3.0 itself is disabled by default. In addition, fallback to SSL 3.0 is disabled since version 34, and TLS_FALLBACK_SCSV is implemented since 35.0 and ESR 31.3.

[RC4-Fx44-74] All RC4 cipher-suites is disabled by default.

[note-d-77] IE uses the TLS implementation of the Microsoft Windows operating system provided by the SChannel security support provider. TLS 1.1 and 1.2 are disabled by default until IE11.

[note-oldieonnt-78] Windows NT 3.1 supports IE 1–2, Windows NT 3.5 supports IE 1–3, Windows NT 3.51 and Windows NT 4.0 supports IE 1–6

[note-k-79] Windows XP as well as Server 2003 and older only support weak ciphers like 3DES and RC4. The weak ciphers of these SChannel version are not only used for IE. They are also used for other Microsoft products running on this OS, e.g like Office. Only Windows Server 2003 can get a manually update to support AES ciphers by KB948963

[note-e-110] Operaعشرة added support for TLS 1.2 as of Presto 2.2. Previous support was for TLS 1.0 and 1.1. TLS 1.1 and 1.2 are disabled by default (except for versionتسعة that enabled TLS 1.1 by default).

[note-Opera12-POODLE-119] SSL 3.0 is disabled by default remotely since October 15, 2014

[note-f-126] TLS support of Opera 14 and above is same as that of Chrome, because Opera has migrated to Chromium backend (Opera 14 for Android is based on Chromium 26 with WebKit, and Opera 15 and above are based on Chromium 28 and above with Blink).

[note-Opera20-POODLE-130] TLS_FALLBACK_SCSV is implemented.

[Opera25-SSL3.0-131] SSL 3.0 is enabled by default, with some mitigations against known vulnerabilities such as BEAST and POODLE implemented.

[note-opera25-132] In addition to TLS_FALLBACK_SCSV, "anti-POODLE record splitting" is implemented.

[note-opera27-133] In addition to TLS_FALLBACK_SCSV and "anti-POODLE record splitting", SSL 3.0 itself is disabled by default.

OS X 10.8 on have SecureTransport support for TLS 1.1 and 1.2 Qualys SSL report simulates Safari 5.1.9 connecting with TLS 1.0 not 1.1 or 1.2

[note-i-144] In September 2013, Apple implemented BEAST mitigation in OS X 10.8 (Mountain Lion), but it was not turned on by default resulting in Safari still being theoretically vulnerable to the BEAST attack on that platform. BEAST mitigation has been enabled by default from OS X 10.8.5 updated in February 2014.

[note-safari-poodle-147] Because Apple removed support for all CBC protocols in SSL 3.0 to mitigate POODLE, this leaves only RC4 which is also completely broken by the RC4 attacks in SSL 3.0.

[note-h-155] Mobile Safari and third-party software utilizing the system UIWebView library use the iOS operating system implementation, which supports TLS 1.2 as of iOS 5.0.
