Certificate expiration handling

We know that during handshake a client's/server's certificate validity (expiration) is checked.
But what about it expires during the run time. I doubt that validity check is carried out once a day or so??? or it occurs once in a session's lifetime?
e.g. I have a certificate that expires on 01/12/2008 and the handshake is done on 30/11/2008.
What happens if the session is still alive on 02/12/2008???

Nothing. But your certificates should be renewed long before there is any risk of expiry during runtime though.

What happens if the certificate expire on a ISE PSN

What happens if a PSN certificate expire? Does all other nodes in the cluster looses the communication channel to that PSN node?
What is the procedure to install a new certificate on a PSN node with the expired certificate?
Does the PSN node still handle client RADIUS requests that does not depend on the PSN cerfificate?
Tanks!

You definitely want to renew the certs before they expire. Otherwise the effects can be very devastating to your ISE environment depending on what the certificates are used for :) Below are a couple of links that you can use to obtain more info on both of your questions:

ISE - What happens when the on-boarded certificate expires?

I'm trying to design a good BYOD deployment model but have a few questions that need direct answers. I have down how to go about on-boarding and getting a certificate on a device, the ISE provides great flow for this to happen in many ways. My questions come from a design perspective before and after the BYOD deployment is completed.
1. Figuring out a method to validate the device is a Corporate asset or a BYOD asset.
     (I don't want to install a certificate on just any device, or perhaps I do but I need to give permissions to all resources if its a Corporate Device, and more resitrictions if it's BYOD, so how do I figure this out during the provisioning phase?)
     a. Use MDM (May not have one, or if you do we are still waiting on ISE 1.2 for that integration)
     b. Build a Group for provisioning admins, if user PEAP-MSCHAPv2 account is from this group install a certificate. (issue here is that the end user looses administration of the device in the my device portal as the device is now registered to the provisioning admin)
     c. Pre-populate MAC into ISE as all Corporate devices should be provisioned by I.T. before they go to the end user (I think this is good but can see push back from customers as they don't want to add more time to the process)
     d. Certs on any IOS or Android device, provide access based on user group and do not worry if device is Company asset or not (I believe that this is the easiest solution and seems to be what I find in the guides)
     e. Other options I have not thought about, would love input from the crowd
2. What happens to the device once the Certificate expires?
     (I don't know the answer to this, my thought would be the user or device will fail during the authentication policy and this creates a mess)
     a. Tell the user to delete the profile so they can start all over again (creates help desk calls and frustrated users)
     b. Use MDM for Cert management (may not have one)
     c. Perhaps the client uses SCEP to renew based on the cert template renew policy and there are no issues (this is me wishing)
Would appreciate some feed back and would like to know if anyone has run into these issues.

Neno,
Sorry but I don't have any other info on using a public CA, Cisco says to use internal CA's for PKI. I think the best practice in 1.2 comes out will be to use one interface for Web Management and a different interface for Radius, profiling, posture, and on boarding. This way you can use your private CA for EAP and a public CA for web traffic. Have you tried a public CA bound to management and a private CA for EAP yet?
I did do a session on EAP-TEAP, they explained how it will work and also discussed EAP-FASTv2. EAP-FASTv2 is available now but you must use anyconnect as your supplicant. Microsoft and all other vendors will have EAP-TEAP native once it is fully released and comissioned as it will be the new gold standard for EAP. It will support TLS, MD5, and CHAPv2. If you are interested I have the PDF of the presentation I attended that shows the flow of how EAP-TEAP will work. This is much better than wasMachineAuthenticated and machine auth caching, which has many down falls.
I currently do machine and user auth I just don't require them. If Machine auth then allow machine on vlan-x with access to AD, DNS, and blah blah. Then a seperate rule to say user auth gets more access, although I require EAP-TLS for both and if you think about it you are accomplishing the same thing if your PKI is setup correctly. Make it so users and machines can only auto enroll, that way you know the only way they got their cert was from GPO policy. I won't go into anymore detail, but there is lots you can do.

Computer certificates expiring within 6 weeks disappearing from machines when computer certificates from two certificate authorities are present

2008 R2 single tier enterprise certificate authority with root certificate expiring within 6 weeks, also domain controller
2012 R2 single tier enterprise certificate authority with root certificate valid for more than the next year, also domain controller
Both servers are approved as certificate authorities for the domain and can issue computer certificates using the computer certificate template. There is a group policy object applied to all workstations that contains an automatic computer certificate request,
but the actual "certificate services client auto-enrollment" element is "not configured". This process seems to work like a round robin in that computers with no certificate can wind up with a certificate from either certificate
authority. I need all PCs to have both certs for a DirectAccess migration. I have successfully used SCCM to ensure all PCs have both certificates using compliance rules and a script using certreq.exe.
A machine will keep both certs until the older computer certificate moves into the 6 week window of expiration, then it gets purged. I have observed this behavior for over a month, even when the CA root certificate wasn't so close to expiring. I
can't figure out what setting is triggering the purge, but need to stop it. Maybe it's coming from default settings in local machine policy for an element that should be disabled in the group policy object supplying the automatic certificate request?
The worst part of this issue is that I can't recreate the purging behavior with gpupdates or restarts on my test machines.

You should not be using Automatic Certificate Request Service (ACRS) for this - it was designed for Windows 2000 and is generally deprecated. Secondly, the reason it is acting like a round-robin as you describe it, is that templates are generally configured
to attempt to renew within 6 weeks of their expiration. Since the 2008 R2 CA is expiring within 6 weeks, it cant issue anything longer than its own remaining lifetime. It is a well known issue that issuing a certificate within the renewal period will cause
problems.
What you should do it use AutoEnrollment and issue a certificate with a very small renewal period (1 week perhaps) by creating a custom V2 template and issuing that from your 2008 R2 CA. Then on the 2012 R2 CA you will need ANOTHER template, as the computer
will only enroll for a certificate from each template. This one can be configured with a normal lifetime and renewal period.

HT201336 Hi I have a certificate expired and was wondering how can I update it ?

I have an apple Iphone certificate expired and I was wondering how do you renew it?

No answers, just some questions... (I'm not sure what you're asking.)
Where did the certificate originate? An Apple iPhone certificate? For what? For iOS development? For VPN? For accessing remote web services, on a server? This is the OS X Server 10.6 forum; are you working with certificates with that operating system, or with certificates on an iPhone?
If your OS X Server system has an expired certificate, you'll need to either purchase a new certificate, or generate a new self-signed certificate and load that via the Certificate Assistant and Server Admin tools.

Portal Certificate Expired with NO VA running!!!

Hi All,
I got one issue about Portal certificate expiration, for which SSO is not working b/w Portal and R3.
As working on Solaris, required to re-generate the Keystore Certificate via Visual Admin, but WHAT!!!
I am not able to run it, it says that JAVA_HOME needs to be set.
Done (Set) but still am not able to see that VA screen. Tried thru root and SIDADM (recommended) also, but couldnt... which is turning my head 360 degrees.
Well request you all to share your good experiences thru which i may be able to resolve the issue which is pending past 2 days and no proceedings since...
And i guess there is no way out to increase the validity of certificate without VA. OR is there any????
Thanks

What happens to Apps when the Distribution certificate expires?

Our distribution certificate expires in mid March. Do I have to re-build all the apps that are on the App Store with the new certificate or will they continue to install without issues?
My gut feel is that Apple would not expect developers to re-submit all their apps just because the certificate has expired but like a confirmation from someone since I am sure many have crossed this bridge.
Thanks in advance.
-TRS

+>I assume that any new submissions will have to have to be built with a profile which includes a valid certificate.+
Of course....just follow the money
It is a solid process, but of course Apple, like any business that operates around time-based/recurring fees, wants to get the 'subscriber' to re-up sooner than later.
The countdown in the dev center, etc. we see about our 'expiration' date is meant not only as a friendly reminder concerning whatever risk, it is a prod to get whatever monies out of our pockets and into theirs...sooner than later

Distribution certificate expiring 3/12. Distribution profile expiring 9/12.

Our Distribution certificate expires tomorrow but the profile is active till 9/12.
So my Q is:
a) If i build something on 3/13 will XCode error out at build time in the CodeSign step?
b) If i build something on 3/12 and submit to Apple on 3/13 will it accept since the Profile is valid?
I am just trying to figure out if i need to wait until i have a new certificate and a new profile before i build my apps.
Thanks,
-TRS

I have not re-newed the certificate so my Q has no relevance now
In any case the answer is that the certificate has to be valid otherwise XCode does not show the profile as selectable. It indicates a disabled information message in the drop-down menu.
Thanks to those who spent their valuable time reading my original post.

SSL Re-encryption with Portal and Web Dispatcher: certificate expired

Hello,
I am trying to set up HTTPS connection to the Portal through SAP Web Dispatcher. We are using SSL Re-encryption. I think I got everything set up correctly. When trying to access through a Web browser the web dispatcher trace file shows error message 'certificate expired'. Looking at the Portal (Visual admin - Keystore) I am pretty sure it is the service-ssl with localhost. It is expired. Two questions:
- is it correct that it uses localhost or am I missing anything?
- How would I recreate the certificate? (I am sure it is somewhere in the Online documentation, but haven't found it yet). Can I do this while the Portal is productive without breaking the normal access (http) to the Portal. This is our Production portal.
Thanks,
Ingrid

Asa ssh/vnc plugins digital certificates expired

Hi,
we've got our new asa set up now (more or less). But what gets us is that the Cisco ssh/vnc plugins and the java applet for port forwarding all come up with "digital certificate expired". Now this is not going to instill confidence in our users.
We are running 8.0(4)3 and asdm 6.1(3) and the plugins are the latest available from Cisco's software download page
(ssh-plugin.08030, vnc-plugin.080130).
Are newer ones available?
Thanks
Dorothea

BTW this could be of help:

You probably want to install a code signer certificate.
While this seems to be what you're looking for, I have never managed to generate a bundle such that Java doesn't complain at all anymore...

You can try removing the expired certificate from the sensor by logging into the sensor's CLI and entering the following commands:
sensor# configure terminal
sensor(config)# no tls trusted-host ip-address 10.1.2.3
Next, tell the sensor to trust 10.1.2.3:
sensor(config)# tls trusted-host ip-address 10.1.2.3

'Certificate Expired/ Certificate Error' in Nokia ...

I have bought a new Nokia N91 8GB. But when I try to instal any application or theme. I get an error saying 'Certificate Expired' or 'Certificate Error. Contact Application Supplier'. Please let me know how this can be resolved.

Hi ismaniyar
Firstly go to Application Manager > Options > Settings and set "Online Certificate check" = Off and Software Installation = All.
Secondly try resetting date on phone to January 1 2007 first and if that doesn't work try December 31 2006 as Symbian certificate may have expired on theme; reset date after installation.
The actual date is a case of trial and error and previously quoted dates may no longer apply due to the passage of time.

SSL certificate expiration CCMS Monitoring

Hi All,
We are using ECC 6.0 server, HP-Unix and Oracle 10.2.0.5 database.
CCMS monitoring is setup in our environment for alerts Monitoring. We use SSL certificates for SSO logins.
As we know SSL certificates get expire in approx one year and when 2-3 days left in certificate expiration system start showing message to all uses for this cetificate expiration.
Now we are planning to include SSL certificate expiration in CCMS monitoring so that whenever before 10-15 days we get a message for certificate expire and we implmenet the certificate without any User intervention.
Now we search a lot but I do not find any option available in RZ20 and RZ21 to include this alert in CCMS.
Please let me do we have any way by which we can get an message of certification before user get this message.
Shivam

Hi Murali,
Thanks for the reply.
I checked links and they are meeting my requirement but one thing I could not find is SSL information in RZ20.
I checked RZ20 tcode and I do not find where SSL information is available to assign auto reaction method to it to start getting Alert.
Can you please help me where I can find SSL certification path in RZ20.
