Default cipher suite used by ASA for SSH?

By default ASA used which encryption algorithm i.e. cipher suite for SSH?
Thanxs

Hi,
To my knowledge it's 3DES/AES.
You can verify with 'show version' and 'show ssh session' commands.

How to add a Cipher Suite using RSA 1024 algorithm to the 'SSL Cipher Suite Order' GPO

Following a VA test the Default Domain GPO has been set to enable the SSL Cipher Suite Order. Following the change Symantec Endpoint Protection Manager doesn't work properly as the the Home, Monitors and Reports pages are blank and an Schannel error is
logged in the SEPM server's event log.
I have spoken to Symantec and I have been told that we need to allow the RSA 1024 bit algorithm but they can't tell me which cipher suite this would be. I have looked in the GPO setting and can't see an RSA 1024 suite but have found some in this article:
http://tools.ietf.org/html/draft-ietf-tls-56-bit-ciphersuites-01
I want to know how to add an additional cipher suite into the setting safely. Am I able to just add the suite into the GPO setting (eg TLS_RSA_EXPORT1024_WITH_DES_CBC_SHA) or do I need to do anything else beforehand?
If anyone has any advice regarding this or cipher suite orders and troubleshooting SSL problems it would be much appreciated,
Thanks
Chris

Hi Chris,
Based on my research, RSA_EXPORT1024_DES_CBC_SHA is a previous cipher suite, which is supported, you can enable it use
SSL Cipher Suite Order policy setting under Administrative Templates\Network\SSL Configuration Settings.

How to specify a cipher suit used between plugin and weblogic server?

I install Weblogic8.1 SP3 which supports for strong cipher suits, and config an apache 2.50 server as an front end.
I config appache to use 2 way SSL with browser and wls one way SSL with apache plugin. Then config apache to forward client certs to WLS. now the problem is, I can see that the SSL connection between browser and apache uses a strong cipher suit('SSL_RSA_WITH_RC4_128_MD5'), but the ssl connection bwtween apache plugin and WLS uses a weak cipher suit('SSL_RSA_EXPORT_WITH_RC4_40_MD5'), with the SnoopServlet, although I use the mod_wl128_20.so module. How can I increase the cipher strength of SSL between WLS and it's apache plugin?
Thanks in advance.
Best

Hello Gunaseelan,
This is not possible because WLS 6.1 needs a config.xml file, exactly this
name, to start.
What you can do is to define a recovery domain, called myrecovery_domain for
instance, and put the config_recovery.xml, renamed "config.xml".
Hope this helps,
Ludovic.

How to locate and configure SSL cipher suites

hi all,
i wanted to knw how Ciphersuites that are used in SSL Connections are picked up by the JVM or whoever is responsible for establishing the connection at lower level. I mean there are methods in SSLSocketFactory, HttpsURLConnection named getEnabledCipherSuites(). I was just wondering where these default cipher suites are picked up. Is there any configuration file or some setting where we can add our own cipher suite to the list?
Please advice.
Thanks in advance :)
Arun

hi,
As already we have discussed this, we can set the ciphersuite used in the SSLConnection using SSLSocket.setEnabledCIpherSuite() function only. And getSupportedCipherSuites() function returns the list of cipher suites that are supported by the connection.
But i want to set ciphersuite in SSLConnection using HttpsURLConnection. Under this class (HttpsURLConnection) there is no such method where u can specify the ciphersuite.
So i am trying to find out when an SSL connection is setup from where does the JVM loads the cipher suites? I checked the All the basic classes in javax.net.ssl package and all contain the methods as abstract. So if anybody has any idea regarding where these supported cipher suites are located in jdk please let me knw.
Thanks in advance :)

Schannel cipher suites and ChaCha20

Is there a blog or other communications channel devoted to the PKI internals of Windows? Most security researchers focus on Linux web servers/OpenSSL, but there are folks in the Windows world who really care about this stuff too, and we'd like to hear
about what the Windows PKI developers are working on and planning, and perhaps interact with comments and suggestions.
Because I couldn't find any discussion about Schannel development, I started a
feature suggestion on the Windows User Voice site for Microsoft to add ChaCha20-Poly1305 cipher suites to Schannel, mostly for the benefit of mobile visitors to IIS websites, but also to help Windows phones and tablets that don't have integrated CPU extensions
for GCM encryption (improved speed and reduced power consumption).
It's frustrating to be a security-focused IIS website administrator. Schannel is a "black box" that we can't tinker with or extend ourselves, and support for modern ciphers has been lagging behind other website and client software (it looks like we'll
at least finally get strong and forward secret ECDHE_RSA + AES + GCM suites with Windows 10 and Server vNext/2016). The methods for configuring cipher suite orders and TLS versions could really use a rethink too (thank goodness for IISCrypto).

Setting cipher suites for ssl sockets

Hi
While setting cipher suites for ssl serversocket and socket, there may be lot of stream ciphers and block ciphers in the list. (also there may or may not be anonymous cipher suites).
How does the ssl socket decide which cipher suite to use?
Sorry for this newbie question.
Thank you.

Have you read the JSSE Reference Guide? It has a really good description of how the SSL handshake works. Part of the "Client Hello" step includes sending all the cipher-suites the client has enabled. The server picks the "best" of that set, that the server also supports, and sends it back as part of the "Server Hello". Both sides switch to that set.
Now, what "best" means isn't defined. I'm not sure what criteria the server uses to determine that. Maybe someone else reading the thread can chime in.

TLS cipher suites: Is there any Windows application that is using one of the two NULL cipher suites?

My question is about these two standard cipher suites from Windows 7/8 (and Windows Servers):
TLS_RSA_WITH_NULL_SHA256
TLS_RSA_WITH_NULL_SHA
Question: Is there any native Windows 7 application/process that must use one of these two ciphers?
If not, I would simply kick them out to make sure that they are never used.
Bonus question: Is there any reason to keep these on any Windows Server?

Thank you for your response. I kicked out the NULL ciphers and everything weaker than 3DES. Consequently I also deactivated SSLv3 on five windows clients (computers and not servers, no server admin here). Rearranged the order of preference according to
my needs. So far I don't experience any issues. Did the same with JRE many years ago (just kicked it out), now I lean back and enjoy the show.

ASA 8.4+ RSA Public Key for SSH user authentication

I have seen in the configuration guide and a separate post in the support community that RSA Public Key authentication is support for SSH sessions in 8.4 and after. I have tried implementing this on both an 8.4 ASA and a 9.1 ASA and I get the same error on both. I have tried specifying SSH version 2 to see if that is the issue but I still get the error. Is there a step I am missing?
Here is the output of the configuration commands:
ciscoasa(config)#username test nopassword privilege 15
ciscoasa(config)#username test attributes
ciscoasa(config-username)# ssh authentication publickey
                             ^

Thanks!

That would be great if the resolution was that simple. I am using a public key I generated using the putty key generator. Below is the key I would use if I got that far. However I get an error on the "ssh authentication publickey" attribute so I never get the chance to enter a public key. What code version and hardware version are you running that this worked on?

Changing the default location PowerPoint uses for templates

I do not want to use the default location MS Office initially configures for templates that is buried in some obscure folder on a local machine in that only Office know about. Instead want to keep my templates in the same location on a company server
with the rest of my materials so I can access it from my company laptop or from the Virtual machines I am forced to use in other company locations. This way I will have my templates everywhere I work. When I make changes they are available to me everywhere
I work and are not buried in a folder on a laptop or a virtual machine in a conference room half a world away.
MS Word allows users to configure this default location for templates but no where in PowerPoint can I find any way to configure this location. Previously on my laptop I have been able to configure the default PowerPoint template location, I believe, by
setting the location in MS Word; however, this is not happening for me now on the virtual machines I am using when away. I have scoured the Options settings and if it is there it is well hidden.
To make matters worse I am trying to use what PPT is providing to me while I sort this out and when you try to open "My Templates": there is a message that says:
"To add a template to My templates, click the File tab, click Save As, click Trusted Templates, and then save the file as a template."
Of course when I follow these instructions there is no folder named Trusted Templates on the left side of the dialog box. I am not sure why it is so difficult to allow us to configure this ourselves for each program but apparently it is.

Hi,
Please refer to this kb below:
http://support.microsoft.com/kb/924460/en-us
As mentioned, if you use Word 2007 or Word 2010 to change the location in which your new templates are saved, you also change the location in which all 2007 Office program templates or all 2010 Office program templates are saved.
Office programs use one registry key to record the user templates file location, you can browse to the following path to check if it's recorded:
HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Common\General
The user templates location is stored in the
UserTemplates
string value.
If it doesn't exist, try to manually add it, check if this helps. Detailed information can also be found in the kb introduced above.
Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps
carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry:http://support.microsoft.com/kb/322756/en-us

By default, on a mac keyboard F3 lets you see all the open apps and the such. However, I changed it so that I use those keys for keyboard shortcuts; But i'd like the normal F3 key to still work without me having to press FN.

By default, on a mac keyboard F3 lets you see all the open apps and the such. However, I changed it so that I use those keys for keyboard shortcuts; But i'd like the normal F3 key to still work without me having to press FN.

rajlego,
in the Keyboard pane of System Preferences, select the Shortcuts tab, and then select Mission Control on the left-hand side. On the right-hand side, make sure that the Mission Control checkbox is checked, double-click on its current key combination (by default “^↑”) so that the key combination is highlighted, and then press the F3 button — that will set its shortcut to be F3. You can now press F3 to bring up Mission Control without needing to also press the Fn button.

I have selected "Use custom settings for history" and pressed "OK" but it defaults back to "Remember history", how do I stop this?

I have to enable cookies in order to have an online purchase credited to my mileage account. So, I opened Firefox Tool and selected Options then Privacy. There, I changed "Remember history" to "Use custom settings for history," as, this will achieve what I am trying to do. However, when I press "OK" the box jumps back to the Privacy box and I see that "Remember history" is still the setting. What steps do I take to prevent the Privacy box from defaulting to "Remember history" when I want to change that setting to something else?

The "Use custom settings for history" selection allows to see the current history and cookie settings, but selecting this doesn't make any changes to history and cookie settings.
Firefox shows "Use custom settings for history" as an indication that at least one of the history and cookie settings is not the default to make you aware that changes were made.
If all History settings are default then the custom settings are hidden and you see "Firefox will: (Never) Remember History".
"Never Remember History" means that Private Browsing is active and "Always use private browsing mode" gets a checkmark.
Do you have a problem with the cookies?
You can inspect and manage permissions for the domain in the currently selected tab via these steps:
*Click the "[[Site Identity Button|Site Identity Button]]" (globe/padlock) on the location/address bar
*Click "More Information" to open "Tools > Page Info" with the Security tab selected
*Go to the Permissions tab (Tools > Page Info > Permissions) to check the permissions for the domain in the currently selected tab
Clear the cache and remove cookies only from websites that cause problems.
"Clear the Cache":
*Firefox/Tools > Options > Advanced > Network > Cached Web Content: "Clear Now"
"Remove Cookies" from sites causing problems:
*Firefox/Tools > Options > Privacy > "Use custom settings for history" > Cookies: "Show Cookies"

How to change the parameter 'Default Servers To Use For Viewing And Modification' using java api dynamically.

Hi,
I need to change the Crystal Reports setting 'Default Servers To Use For Viewing And Modification' to a particular server.this i need to do using java api.
could you pls provide me the sample code for this.
Regards
Srinivas

The IReport interface extends IViewingServerGroupInfo interface, that allows you to specify the server group.
The choice selection for that interface is as follows: 0 = first available, 1 = prefer the selected server group, and 2 = only use the selected server group.
The server group selection is by the SI_ID for that server group InfoObject.

How to use php variable for default tabbed panel

I have a tabbed panel and with tabs labelled with the days of the week. What I want to do is open up the tab that correspond to the current day. I have been using the following to get the day in 3 char format:
<?php
$jd=cal_to_jd(CAL_GREGORIAN,date("m"),date("d"),date("Y"));
echo(jddayofweek($jd,2));
?>
What I want to do is replace the value for the default tab in the following statement with a variable that matches the day returned with a number:
var TabbedPanels1 = new Spry.Widget.TabbedPanels("TabbedPanels1", {defaultTab:1});
Please could anyone advice?

Hi,
BIND_VARIABLE is useful when you have only IN variable but in your case you have IN and OUT.
I don't know if you use the gateway for MS SQL SERVER or HSODBC/DG4ODBC but here how you can do to call a remote procedure with bind variables:
DECLARE
ret integer;
inp varchar2(255);
outp varchar2(255);
BEGIN
inp :='Hello World';
outp :='';
ret := "dbo"."in_out_proc_test"@tg4msql( inp, outp);
dbms_output.put_line('Input value: ' ||v_ut1||' - Output value: '||v_ut2);
END;
The MS SQL Server procedure belongs to the user "dbo" and the database link
being used is tg4msql.
The following line initilaize the out variables of the procedure with an
empty string:
outp :=''
I hope it helps you.

I have a macbook air/ipad/phone, etc. I use my macbook for my home business and bought a TC. My husband does not want it to be our default wifi. Does it have to be?

I have a macbook air/ipad/phone, etc. I use my macbook for my home business and bought a TC to do backups. My husband does not want it to be our default wifi/modem as he is exclusively a PC user. Does it have to be? I thought it did everything wirelessly?? I don't want to start disconnecting our modem/router etc as we are all set up with wireless printing and backups for that computer. If I have to muck around with it I am thinking of not bothering??

The TC will connect to your existing modem/router using an Ethernet cable. You will not have to use the wireless on the TC....you can even turn it off if you wish.
Backups to the TC will occur over your existing wireless.
Connect from a LAN <-> port on the modem/router to the WAN "O" port on the TC. Locate the TC anywhere that the Ethernet cable will reach. You can run the cable up to 300 feet with no loss.
Things will not automatically configure themselves. You will have to do some mucking around....no more than you would if you were installing the TC anywhere else.
Configure the TC to "create a wireless network". Once it is setup, you can ignore the TC wireless, or turn it off.
