12 TopicsRelation between Cipher-Suite and Key-type of server certificate
I must noticed/learned these days, that specific allowed ciphers are useless if they are not matching with the key-type of the server-certificate from the clientSSL profile. I think it's not unusual that most server-certificate will still be generated with RSA 2k or 4k key-type. And those (older) certificates, which are already renewed a couple of times with the same key have even a higher chance to be a RSA type. But with this for example only the following two ciphers could be selected: ECDHE-RSA-AES128-GCM-SHA256/TLS1.2 ECDHE-RSA-AES256-GCM-SHA384/TLS1.2 If a client for example only supports the following two ciphers: ECDHE-ECDSA-AES128-GCM-SHA256/TLS1.2 ECDHE-ECDSA-AES256-GCM-SHA384/TLS1.2 Neither of these two will be choose, even if they are allowed/provided in the cipher-rule configuration of the BIG-IP. Is this really the case or are there any other dependencies, which are responsible for the „No shared ciphers between SSL peers“ log entry? I'm wondering, because I've never read about that in any of the tons of cipher documents and articles, I've read so far. => So can please someone share some detailed information about this relation? And if this behavior is true, does it makes sense and is it technical possible to create two different clientSSL profiles, one with a RSA-key and the other with a ECDSA-key and assign both to the VIP? Can the BIG-IP handle this and will choose the correct certificate/profile depending on the provided cipher-list from the client? Thank you!

Hello, we usually log in to our BIG IP with TACACs, working fine, now we'd like to have a special user, who should authenticate with rsa pub key. question: when I create a user, I can not define a password, I guess because of the AAA-Config, right? So I fear, this would only work, if we disable TACACS. If we configure the root-user with rsa pub key, there's still asking for Password. has anyone such a combination?306Views0likes2Commentsusing the F5 for RSA Selfserviceconsole on port 7004
Hi out there I am (still) trying to get the RSA selfservice portal published via the F5 on a std SSL port. I have defined a default pool for the RSA server on port 7004 and I am publishing the external server on 443 I have put this irule on my VS running on port 443 and having the default pool for the intern server on port 7004: when HTTP_REQUEST { Disable the stream filter for requests STREAM::disable Remove this header to prevent server from compression response HTTP::header remove Accept-Encoding } when HTTP_RESPONSE { set internal_host "rsa.intern.local:7004" set external_host "rsaselfservice.extern.com" Rewrite the Location header for redirects if { [HTTP::header exists Location] }{ HTTP::header replace Location [string map "$internal_host $external_host" [HTTP::header Location]] } Rewrite the response content using a stream profile if it is text if { [HTTP::header Content-Type] contains "text" } { Set the stream expression with the find/replace strings STREAM::expression "@$internal_host@$external_host@" Enable the stream filter STREAM::enable } } but I get a 302 in return and it looks as if it loops a bit - can some tell me what is wrong with this little simple irule? Is it the response to the client which not gets correct re-written? br /ti329Views0likes2CommentsRSA Self Service iRule no longer works
I upgraded from 11.2 to 11.6 and the RSA secureID selfservice page that was working is no longer working. I have an irule that we are using Code when HTTP_REQUEST { if { [HTTP::header host] eq "PUBLIC.URL.COM" } { HTTP::header replace Host "ACTUAL_SERVER_FQDN:7004" } } when HTTP_RESPONSE { if { [HTTP::header Location] eq "ACTUAL_SERVER_FQDN:7004" } { HTTP::header replace Location [string map -nocase {ACTUAL_SERVER_FQDN:7004 PUBLIC.URL.COM} [HTTP::header value Location]] } } Everything was working great until we upgraded to 11.6. Now it looks like the http response part of the irule isn't working. Any updates to this irule to get it working in 11.6? Thanks!276Views0likes5CommentsImpact when moving from 2048 to 4096 bit RSA keys
Hi, I am trying to determine the impact of moving from 2048 bit RSA keys to 4096 bit RSA keys for a clientside ssl profile and would like to get some details of the impact when doing so. I read that the TPS would drop to 20% of what we would be capable when staying on 2048 bit keys. Assuming unlimited license. How much more latency would we have to face in the handshake process? Is there a list of incompatible clients available? Something like 'Outlook 2007, Firefox 12, ...' How much will the increased keysize strengthen the tls connection assuming we stick to the same cipher? Any other sideeffects? I did also open a F5 support case to this (C2910446 - Analysis of impact when moving from 2048 to 4096 bit RSA keys) but I was wondering if anyone from the community got some interesting ideas/comments to share. Once I get a proper response from F5 support I can share here as well as I think many might be interested.

Hello guys, Hope you could support me in the following matther. I have already purchased an ECC wildcard certificate and I wanted to attach it to a virtual server in my BIG IP 4200 LTM box which is running version 12.1.2. Everything went well until I got an error when creating a SSL client profile. It said "010717e3:3: Client SSL profile must have RSA certificate/key pair.", so I investigated and found that it is needed to have a RSA certificate/key in the profile besides the ECC pair. Therefore, I have the following questions about it: Do I need to generate two certificates (one ECC and other RSA) with the same FQDN on them? Is it possible? I am using Entrust to generate my certificates. How could I figure out which one certificate the BIG IP is showing to the client? How does the BIG IP select which certificate to show? Is there any possibility to make the BIG IP allows the creation of an SSL profile which uses an ECC certificate/key? In future releases perhaps? I have performed a couple of tests and it seems like the BIG IP is always showing the RSA certificate. Thanks in advance for your help. Best regards1.4KViews0likes9CommentsAPM with for VMWare View with RSA auth.
So I'm trying to setup APM with VMWare View and RSA. I created SecureID View Client Logon and the user enters their email address and RSA key. Next I have the RS SecureID Auth configured but it looks like it's only passing the user name and not dot the full UPN, stripping off the domain name. RSA rejects the user since it does not have the full email address. Thanks627Views0likes10CommentsSecurID Authentication Failing on APM 12.1.2
I am having issues with SecurID authentication on a POC APM deployment. My first authentication attempt succeeds but any attempt after that fail with the following error. [root@AKOHDCPOCLTM01:Active:In Sync] config /usr/local/bin/securidtest -p "/config/aaa/ace/Common/rsaama01pakr.bfusa.com" -s 10...* -u username -w ********* ERROR: authentication with 'username' failed in doAuth:SD_Check(): authentication failed, code: 1, state: SECURID_AUTH_STATE_ACCESS_DENIED Test done: total tests: 1, success=0, failure=1 Some fields changed for privacy I can get a single authentication test to work by deleting the 'sdstatus.12' file. RSA is not able to tell me why that makes a difference. Any thoughts on this?330Views0likes1CommentRSA page error
The BIG-IP web logon page does not display prompt text from SecurID RADIUS access-challenge packets. This issue affects new PIN, next Tokencode and on demand authentication flows. When the user starts any of these flows they will only get a text field with no description for what to enter. See image below. Nat245Views0likes4CommentsAPM, use HTTP basic auth semantics to retrieve e.g. RSA credentials?
Hi all - new-ish to APM - I think this is possible, but wanted to check. Rather than using a form to gather credentials from a user, is it possible to use the HTTP basic auth authentication scheme to gather the credentials, but configure the access policy so that the retrieved credentials are sent to an RSA server (accessed as a RADIUS AAA)? We already have a portal link working, with a form for user credential gathering - but we have some scenarios where it would be better if the client received an HTTP 401 status back, and gathered credentials via the built-in basic auth dialog. This is on 11.5.1 LTM (APM 11.5.1). Thx for any help!220Views0likes1Comment
