ASA5505 IPSEC only with self-signed certificates

Hi all

I have little Cisco training and was assigned to a pilot project. We have cleaning of the ASA from another Department, but I do not have access to support. It is running ASA v9.1 and ASDM 7.1. If all goes well I'll be sent on training and we can buy a nice 5520.

So I scoured the internet for a guide that is easy to do as my title says, but I'm having major trouble. I find a lot of outwardly signed with self-signed SSL VPN or VPN IPSEC with CERT support but I can't only get ASA self-signed IPSEC IKEv2 with certificate authentication. Also, to make it even worse, I have to provide the user with the software, the profile and the certificate in hand. No access to the web or download portal.

If you know where I can get good installation guide for this type of use please by all means save me here. If this isn't possible, I'm cool with that, let me know.

Thank you fo any help you can provide

If the ASA uses a certificate issued by a certification authority that is in-store customer trust root CA, then the certificate of identity ASA didn't need to be imported by the customer.

Which is why it's usually recommend to follow the path of using experienced public CA because they are alreay included in most modern browsers and so the client has no need to know how to import certificates etc.

If you are using a local certification authority that is not in the store trusted CA of the customer to deliver your ASA certificate or identity certificates on the SAA signing root then you must take additional measures at the level of the customer.

In the first case, you could import the CA certificate in the store root CA of the client trusted root. After that, all the certificates it has issued (the IE the ASA certificate of identity) would automatically be approved by the customer.

On the second case, certificate of identity of the SAA is would have installed on the client because it (the ASA) basically as it's own root certification authority. Usually, I install them in the CA store root confidence of my client, but I guess that's technically not necessary, as long as the customer knows to trust this certificate.

  • ASA SHA2 support with self-signed certificates

    Is it possible to use the signature SHA2 algorithm generating a certificate self-signed on an ASA? I can't find any documentation on orders that have control of things like the signature algorithm when you use self-signed certificates. I have seen documentation SHA2 is supported from 8.4.2 for the signature algorithm, but it always refers to the import of a certificate from an external certification authority.

    Hi William,.

    You can only generate self-signed certificate on the SAA SHA1. The solution is to import a certificate from a 3rd party with signature SHA2 algorithm.

    Here is the value for the same application:-

  • RTMPS with self-signed certificate

    Hello

    I have a simple Webcam movie, publish live video
    FMS 2.0.2 r51 dev under Debian 3.1r2 edition
    and then he plays in another video-window.

    It works very well and rtmp, rtmpt, but with rtmps I get
    the error "NetConnection.Connect.Failed".

    I have prepared a simple and all assembled test scenario
    info here: http://pref.dyndns.org:8080/live/live.html

    The certificate has been created by me in this way:
    openssl req - x 509 - days 365 - newkey rsa:1024.
    -self-signed - certificate.pem - keyout pub-sec-.pem

    And implement defaultRoot_/Adaptor.xml:

    ... jumped...

    I'm sure that the server works as I see in the var:
    localhost adapter [2675]: listener started (_defaultRoot__edge1): 443 (secure)

    I also tried to put
    Import mx.remoting.Service;
    Import mx.services.Log;
    Import mx.remoting.debug.NetDebug;
    NetDebug.initialize ();

    at the top of my AS code, but the NetConnection debugger

    I found the solution-

    If a pop-up window of dialogue for a reason any
    (as unknown CA or not is not host name)
    then the cert will be rejected even if you
    Click 'yes '.

    If you are generating a cert self-signed like this:

    OpenSSL genrsa-des3-out ca.key 4096
    openssl req - new - x 509 - days 365 - key ca.key - out ca.crt

    OpenSSL genrsa-des3-out server.key 4096

    OpenSSL x 509 - req-days 365 - in server.csr - CA ca.crt - CAkey ca.key - set_serial 01 - out server.crt

    (increase the 01 above for each new cert).

    and then import the ca.crt from above in your
    browsers (i.e. double-click on Windows for IE
    Open from Mozilla Firefox and click OK).

  • ASA - a Site with self-signed certificates

    Team,

    ASA version 9.1 (3), ASDM 7.1 (4) on 5505.

    I have a pair of Cisco ASA 5505 that I am trying to establish a tunnel. I do everything with PSK. IKEv2 with AES256 IPSec. No problem...

    However, I learned that I can auto-signer certificates and use them to authenticate each firewall to another. I tried for hours... Generating of certs in all combinations and options, and the export of the P12 in the other firewall, by adding in - no problem

    I have self signed CERTS, so there is no CA.

    Then I'll be back in the connection profile and remove the PSK - flip on to RSA - SIG in the IKE Policy.

    Does anyone have this working with the ASA version, I'm running and care apart from your snippets of configuration especially how you created the pair of keys, self-signed one, exported and adding in the adjacent firewall?

    I don't want to use PSK for authentication.

    Help!

    I never used this way without a CA so I can't guarantee that it will work, but one thing is often forgotten with digital certificates: you assigned the ID-Cert cert in the crypto-plan?

  • Safari no longer works with SSL self-signed certificates?

    With the last Safari (9.0.3) on OS X (running 10.11.3) and iOS (9.2.1) operating system, I can no longer connect to sites that use self-signed SSL certificates. Previously, I was warned that the site certificate was not "valid", but given the opportunity to continue anyway. This is the behavior I want to come back. It still works fine in Chrome, Firefox. but now just Safari gives me an error "Safari can't open the Page" as it would if it could not reach the server. Specifically, it says "Safari can't open the page https://myselfsignedhost.com because Safari is unable to establish a connection to the server myselfsignedhost.com.

    It does not give me the opportunity to inspect the certificate, add the certificate to my keychain, trust the cert, ignore the warning once or anything else that would be useful... He's just pretending like it can't connect. Am I missing something? How to restore old functionality? This 'bug' makes safari completely useless for me.

    OK, some info... This seems to apply only to SOME sites with self signed SSL CERT... The only obvious thing I can think is that maybe it applies to sites where the SSL certificate when the page was first loaded?

    If I open a new window private, I can access the page without problem. If I open a new standard, I can also open the page, until I quit safari. Once I left, it stops loading with the same error...

    If I manually add the SSL certificate to my keychain as being approved, the page also works... There may be a cache of certificate somewhere that is out of date?

  • Self-signed certificate installed successfully but with VR error device

    HI gurus,

    I'm in the middle of the upgrade of RS 5 5.1 RS for replication of vSphere.

    I'm trying to install and register the device VR 5.1.

    On the configuration tab I filled out the Info: and tried to produce the certificate and start the service.

    It comes up with the following msg.

    Self-signed certificate installed successfully.

    WARNING: Bad service state: execv() arg 2 must contain only strings.

    The info I have completed are as follows:

    VRM Host: ip address of host vrm

    Name of the Site of VRM: virtual site of DR (FQDN) appliance

    vCenter Server Address: address of the server vCenter DR FQDN

    vCenter Server Port: 80

    vCenter Server Admin Mail: e-mail administrators

    Thanks in advance!

    Here's your answer...

    Edit the/etc/sysconfig/network/config file.

    Find this line:

    NETCONFIG_DNS_STATIC_SERVERS = «»

    Change the line and put a DNS server IP address in quotes.

    Restart your device and try again.

    Edit: Still one thing, make sure that you deploy the version of the appliance corresponds to your version of vCenter. vCenter Server 5.5 uses the replication device 5.5, 5.1 VC uses 5.1 etc.

  • Faced with Windows 2008 R2 PKI, self-signed certificates &amp; view iPad customer Secure Authentication to view connection server: UGH!

    Background: I was instructed to create a VMware View isolated laboratory test so that HIGHER-UPS can see how they could access the VM dedicated as well as how their developers could put related clones on-the-fly. The project was successful! Yay!

    Addendum: A boss wants to see how VMware View works when accessing his computer virtual dedicated via his iPad on the internet... And who needs a secure SSL connection.

    The problem is: the domain name I chose casually because the lab did not belong to me... So I can't have a real certificate from a trusted commercial certification authority.

    So I'll try to roll my own public Windows 2008 R2 PKI and... All that forcing the iPad to use DC/DNS server in the lab... Get only the single get iPad trust view connection server by importing a sort of certificate.

    Can I export/import a certificate of the CA of DC to the iPad via an attachment... And it happens with confidence. But how to create a login to view the server certificate and electronic-mail/import in the iPad so it happens with confidence? Whenever I try to export the certificate of the certificate of the view connection server store, send it to the iPad and install... The connection server certificate appears as 'not reliable' and the VMware View client will not connect.

    (Of course, I could get sloppy and set the iPad Client to accept untrusted connections... "But I want to solve the problem of approved connection).

    I could be missing something royally on the self-signed certificates and certificate chains.

    (It is a first for me dealing with Active Directory Windows Certificate Services. In the past, I always just installed expensive commercial SSL CA certificates in the certificates Windows Server stores before.)

    Any help or direction, you can provide would be appreciated. I'm rather confused.

    See you soon!

  • Can I generate self-signed certificates free for Nexus 9 K?

    I use vRealize Orchestrator for automation, and I can't access the REST API on the Orchestrator help link, as certificates are at expiration.

    I can't find much information on this subject for the 9 K, unless the 9Ks are mode of the AIT, in this case I think that TACS are the only people who can generate a certificate.

    Does anyone know otherwise work around this? Otherwise, I'll have to approach a TAC case for 22 certificates generated :-/

    After this make sure that you do NOT change the host name of the device :)

    The failure of the handshake could occur for various reasons:

    • Incompatible encryption suites in use by the client and the server. This would require the customer to use (or allow) a suite of encryption supported by the server.
    • Incompatible versions of SSL in use (the server can only accept TLS v1, while the client is capable of using SSL v3 only).
    • Incomplete trust for the certificate of the server path
    • The certificate is issued to another area.
    • incomplete certificate trust path between the certificate for the server, and a certification authority root.
    • In most cases, this is because the certificate is not present in the trust store
