6 * be consistent: 2048 RSA < 128 bit symmetric cipher strength. We should aim at 128+ bits symmetric strength. --> fix RSA 2048 in the document. Upgrade to 3072
8 * clean up 9.5 "chossing your own cipher"
10 * DDOS possibilities when we increase cyrpto security?? What about that? (--> LATER)
12 * write a Justification section to every setting, maybe have that later in the document.
14 * more focus on these sections:
16 - SSH : do we need a client subsection?
18 DONE * move the explanations to a later part of the document. Code snippets go *first* . The target group is sysadmins, must be easily copy & paste-able. Or find a different way so that they can easily use/read the document
20 DONE * Decide/Discuss recommended ciphers:
21 - DH parameters: what is our recommendation? >2048? >=2048? leave default (aka 1024)?
22 --> answer: we trust IETF/IKE as described in ECRYPT2
24 * comments from IAIK integrate (--> Aaron, check again if it was done)
25 DONE * SHA-1 section: write why it is a problem (--> Florian Mendel)
26 * PKI section (--> Thomas Schreck)
27 DONE * include OpenSSL names/IANA names into appendix (--> cm)
28 * Document RNG problem in Apache (--> Pepi)
29 DONE * Oracle ?? (--> Berg?? maybe . Or aaron: ask nic.at. Or link to T-Systems paper) --> T-Systems paper
30 DONE * DB2 (--> Berg. Or ask MLeyrer)
31 * Add AES128 to cipherStringA ?
32 * re-work chapter 2 (practical settings). Add lots of references to chapter 3 to get people interested in reading the theory.
37 People with outdated browsers (winXP) etc can't see our webpage. --> make a landing page explaining
38 how to updated the browser :)
44 DONE * one-column layout: make page margins smaller
45 DONE * add large "DRAFT" letters on top of every page.
46 DONE make the git version number part of the document
47 DONE * Layout of sample code (lstisting format) : make it pretty!
48 Rendering in Firefox (inline) on Windows seems to be really messed up. What happenened?
50 * make every section like the Apache section (--> Aaron)
52 * make a HTML Version of the document. It is much easier to copy & paste from than from PDFs.
53 * Add Timestamp and git shorthash, not only date, to the title page of the document. Easier to check if you version of the document is current!
58 Requested by many people on Twitter
59 * Plain TXT version for use on headless servers
60 * HTML version for better reading in browsers and always up-to-date
61 * EPUB version for comfortable reading on tablets and ebook readers
67 * how to keep things up to date?
68 * how to automatically test compatibility?
69 * how to make sure that this document has the latest information on cipher strengths?
70 * !! GPG sign every PDF !!
71 * store the keys in DNS: see RFC 4398
76 * scan our local region of the internet for https/smtp/imaps/pop3s
80 - key management , key life cycle
82 - common / default passphrases
86 * Wish List for software vendors?
87 * sweet spot, wo koennen wir was sinnvoll machen, was waere zu viel (8192 bit keys...)
90 1. document the abstract needs that we have for the cipher settings (HSTS etc)
91 Then find the best cipher setting strings per se
92 Only then put it to all servers and keep it rather uniformely (as much as possible)
96 * Test especially with non-Debian-OS!
98 * Test with more clients and other OSes than OSX / iPhone!!
103 - Playstation und XBox? --> LATER!
106 - Windows Phone 7 ???
108 - chapter owner makes a test setup
109 - tested by: XXX , on: $date. Screenshot of SSLlabs/ $testtool. (checktls.com)
111 * document (cite) EVERYTHING! Why we chose certain values. References, references, references. Otherwise it does not count!
113 DONE * .bib file is completely wrong. Make good citations/references. Add books: Schneier, ...
114 * !! important: add the version string to everything that we tested!!
117 - security specialists / freaks who want the very best settings
118 - should as many clients work with the settings as possible
119 * look at TLS1.2 specs and really check if we want all of these settings
122 Practical settings section
124 Definitely still missing these subsubsections:
125 * Exchange Server ?? (--> bei M$ angefragt, Evtl. Beitrag von A-Trust)
127 DONE * Exim4 (-> Adi & Wolfgang Breya)
128 DONE * Checkpoint (-> cm)
129 * Asa / Palo Alto (-> Azet)
130 * Terminal Server (VNC ), ??
133 --> verweise auf die xmpp community bzw. auf xmpp.net verweisen.
134 Empfehlung: unbedingt ejabberd updaten!!

208 * Windows Active Directory
209 DONE * SRP: not part of this document. But we did not exclude it in our cipher string :)
210 DONE * \cipherA , \cipherB setting ---> does not work in our \begin{listing} environment --> maybe there is a different listing environment or use awk/sed/make/perl/python
211 * What about 3270 terminal emulation? How to do crypto there? Can we? ( --> IBM sec. Stammtisch. Aaron)
