Can someone help me to understand using self-signed certificate for BIGIP LTM box falls in non-compliant as long as our device will be accessed only by network administrators?

    Hi,

    Using self-signed certificates can pose a number of challenges, severals attacks have successfully exploited self-signed certificates (MitM attack, Drye Banking Trojan etc.)

    So, even if your device is only access by network administrators, it's not something to be advised (there's a risk if one of the admin account or admin access is compromised)

     

    A good article on this topic : When are self-signed certificates acceptable?

     

    Regards

    Hello NetWork.

     

    Migrated from another thread:

    Self-signed certificates cannot be used to authenticate sites.

    Base on this, someone accesing one specific device cannot be sure that the device which is accesing belong to the person/company that user thinks it belongs.

     

    To be more precise, someone could be performing a MITM attack in that communication and you couldn't be aware of that.

     

    Regards,

    Dario.
