Bypass, in general, means either to go around something by an external route rather than going through it, or the means of accomplishing that feat.

Bypass, in general, means either to go around something by an external route rather than going through it, or the means of accomplishing that feat. In network security, a bypass is a flaw in a security system that allows an attacker to circumvent security mechanisms to get system or network access. The actual point of entry is through a mechanism (either a hardware device or program, even just a piece of code) that enables the user to access the system without going through the security clearance procedures (such as authentication) that were set up by the system administrator. A bypass may be a mechanism put in place by an attacker, a flaw in the design, or an alternate access route left in place by developers. A bypass that is purposefully put in place as a means of access for authorized users is called a back door or a trap door. A crypto bypass is a flaw that allows data to circumvent the encryption process and escape, unencrypted, as plaintext.
