Trusted Man-in-the-Middle

Hi,
I'm trying to build a trusted man-in-the-middle with JSSE and HttpClient .
My main objective is to implement a proxy in order to control flow over my server.
Can anyone help me with references, examples, or any other thing?
I'm new to both technologies, so any help is appreciated!
Thanks in advance!
Regards,
Pedro Lemos

That one is pretty easy. Make an ordinary SSL connection to the proxy. This connection will be made by the browser itself.

Then have the proxy make an ordinary SSL connection on to the server.This one I need to do. I understand that.

Change the DNS records to treat the proxy as the server.When using JSSE, i need to change DNS?
I'm new to JSSE, but haven't seen any mention to DNS changes...

Does that make sense? Is that the usage you're looking for?It does makes sense, but not with JSSE usage, I think... correct me if I'm wrong.
What I'm looking for is an implementation to do it within JSSE framework.

  • Man in the middle

    Guys whats the best defense against Man in the middle attacks???
    for Client Server apps

    What normally prevents a man-in-the-middle attack is a certificate authority such as Verisign. Verisign acts as the trusted third party in an exchange. They certify that the public key you receive was transmitted by the proper sender.
    As an aside, you also have to worry about replay attacks. These can easily be stopped by embedding a timestamp in the encrypted message payload.

  • SSL and Man-in-the-Middle

    Ok guys,
    First, I'm not up on security issues. I had a security expert look over
    weblogic and SSL. He said that SSL was NOT a good protocol. It is what we
    are stuck with. He demonstrated in a matter of about 30 minutes a technique
    he called Man-In-The-Middle attack and was intercepting SSL traffic between
    the outside world and Weblogic SSL.
    Now the question. Is there any way to detect this or stop it from happening?
    Welogic never detected a security breach. I saw this demonstrated and know
    it can be done. How do you prevent this? Should there be a way for Weblogic
    SSL to detect if somone is doing this?
    Thanks,

    An SSL man in the middle attack is possible if:
    1) The attacker manages to obtain your private key. Good server security
    should minimize the chances of this happening.
    2) The attacker can insert their own CA certificate into the browser and use
    this certificate to sign their own server certificate. This is tricky and
    can only be done if the attacker has some sort access to the machine(s) on
    which the client browsers run.
    3) The attacker manages to get a certificate from a CA your browser trusts
    and that certificate contains the common name of your server. This one
    basically requires the CAs misuse their keys. Hopefully this doesn't happen.
    4) The attacker uses their own server certificate and the user blindly
    clicks through the warnings the browser provides. There is nothing really
    that can be done to stop this one. If the user wants to ignore the warnings
    their browser pops up then that's their problem. Of course there are
    browsers out their that won't display any warnings (I'd say people shouldn't
    be using such browsers but then the vast majority of internet users don't
    have the security education or experience to make decisions like that
    themselves).

    Tolu,
    No he didn't break it. He acted as the middleman. The server thought hewas
    the client and the client thought he was the server. He just set in the
    middle and swapped all the keys, then collected all the data. He had apiece
    of software commonly available on the net for doing this.

    Hi,
    do you mean he was able to break the key exchange protocol?
    A ssl session involves a handshaking period during which, based on a keyexchange protocol a pair of assymetric keys are used to negotiate asymetric
    key that will be used to encrypt data exchanged within that particular
    session.
    This is an interesting issue and I think it will serve the community
    well
    if you asked your security expert to let us know what he/she actually did.

  • Detect attack man in the middle with IDS/IPS

    Hi,
    I have aip-ssm 20, IPS Version 7.0(6)E4
    The ID  signature 7101, 7102, 7104 and 7105 is used for detecting attack arp poison.
    The sensor works as IDS in promiscuous mode. All traffic is fordwared to sensor.
    I have made attack man in the middle with cain & abel but sensor doesn't send alarm. I attach image with signatures.
    Why don't sensor detect attack? The network is in zone inside.
    Can anybody help me, please?

    Did you check if SSM is getting those packets by running "packet display .." command on the sensing interface. In SSM the ARP packets would not be forwarded by ASA to the SSM.
    thx

  • Is FEP 2010 capable of securing computer against the man-in-the-middle attack?

    Hello
    Just would like to know if FEP 2010 is capable of preventing man-in-the-middle attack on computers with it installed?
    Thanks

    It is not the job of FEP or other Anti-Malware product to protect you against man-in-middle attacks, as it is not purpose of design of Anti-Malware. However, some of Man-in-Middle attacks are being blocked by Network Inspection System (NIS), which means
    if FEP detects any malicious package on a network which match signature of NIS , it will block it.
    Browser plays a very important role in blocking Man-in-Middle attack, for example if you use Internet Explorer, you have a better protection against this type of attack, take a look at:

  • Diffie-Hellman Algorithm and Man-in-the-middle attack

    From the RSA Security site, it says that Diffie-Hellman Algorithm
    is susceptable to the Man-in-the-middle attack, because there
    is not mechanism to prove the authenticity of the public keys
    being exchanged.
    Is it true then, the only way to protect against this,
    is the use of a signed certificate?

    or rather, the only way to protect against
    the attack is to authenticate before generating the
    DH secret key.
    signed certificates are one way of authenticating,
    userid/password, hardware token, biometrics are others.
    i guess you could use any of these after looking at
    trade-offs between security/useability.

  • SSH Man-in-the-middle Attack

    I currently am living abroad and use ssh to tunnel back home to a couple of different networks and servers. Recently my ISP wired my building for a new high-speed line, however I suspect a rogue tech has wired a man-in-the-middle machine between me and the internet. Am I crazy?
    Now when I try to connect to any of my back home networks, I get the warning "The server's host key does not match the one cached in the registry ... the new rsa2 fingerprint is: "xx:xx:xx:xx:yadayada".
    This same "new" rsa2 fingerprint pops up regardless of the network I try to connect to. This alone is suspicious, because each network should have a unique fingreprint. Regardless, I double checked and confirmed it is not one of my valid host keys.
    I can connect without this warning as long as I am not at my home network, and the cached host keys are still valid.
    I am left to believe that there is a device (with fingerprint xx:xx:xx:xx:yadayada) sitting between my router's WAN and the ISP's router's LAN.
    Is my ISP trying to steal my passwords? is there another logical explanation? If I do have a man-in-the-middle, how do I get him to go away? Can I bypass him?

    Below are (4) connections with *ssh -v -v -v*:
    The first two are connections to two remote hosts on a safe connection
    The last two are connections to the same two on the connection in question
    Not the last two give the man-in-the-middle warning, and share the SAME 'new' rsa fingerprint, I dont know why these would be the same unless there is a man in the middle.

    A lot of ISPs do so in order to create a revenue stream for fixed IP addresses. They rotate addresses so subscribers won't run Web, mail, ftp, etc. servers without paying for the bandwidth use.

  • Strange small glyph in the middle of the screen when using LabVIEW 8.2.1

    I've started noticing a strange small glyph in the middle of the screen when I am using LabVIEW 8.2.1.
    Sometimes it is there, sometimes it isn't. Has anyone else seen this? Why is it there? Can I get rid of it?
    (Just in case you think I am going crazy from too much LabVIEW I'll include a screen capture of it...)
    Well that's it. I barely noticed it on my blue/ background picture. It seems to be there on my XP machine but not my Win2K machine.

    It's something from your video driver (If I recall correctly an NVIDIA).
    LabVIEW creates somewhere off-screen a window with  a size of 0,0. The driver detects this and as som sort of anti-spam moves it on-screen.

  • How can I center my website to the middle? My website, not my writing if it helps understand it better

    I wanna center my website to the middle of the screen, not left align. My writing is centered on the website but the site I created is stuck in the left side.

    Hello,
    please try in your css advice:
    #main {
      width: ....px; /*(Your choice)*/
    margin: 0 auto;
    In German: Indem man die Breite (width) eines Block-Elements definiert, verhindert man, dass es sich nach rechts und links bis zum Rand des umgebenden Containers ausbreitet. Durch Setzen des rechten und linken Außenabstands (margin) auf auto lässt sich das Element horizontal zentrieren. Das Element nimmt so die definierte Breite an und teilt den verbleibenden Außenabstand gleichmäßig auf.
    My try in English:
    By the width (width) defines a block-level element, it prevents it from spreading to the right and left to the edge of the surrounding container. By setting the right and left outer distance (margin) to auto can be the element horizontally center. The element that accepts the defined width and divides the remaining outer spacing evenly.
    Hans-Günter
    P.S.

    I am transferring my 2009 27" iMac to a new 27" 768gb flash drvie with 32gb ram via wireless and it is taking 110 hours and has been on overnight. I have the thrunderbolt to firewired adapter but I could not get it to mount my
    buffalo thunderbolt external even though it mounts my firewire Lacie 800 which is why I am doing it wirelessy I do not have 110 hours it is work related computer I run three companies.
    can i plut in the thunderbolt and try it with the firewire adapter in the middle of migration and remove the ethernet cable it was only 50 hours when it was doing it wireleslly and now 110 with the ethernet cable I am going to try removing it at least.

    You run three companies. That means that the cost of your time exceeds what should be invested to migrate your data. It also means that a keen business mind quite often does not have the patience for this sort of thing. Pay someone you trust $100 to do this migration for you, and repurpose your current stress levels into new 2013 business opportunities.
    $100?
    That is a very small price for such a high value migration.
    Re-assess your rates
