Multi-party authorization
open-in-new
<p>Multi-party authorization (MPA) is a process to protect a <a href="/facts/Telecommunications_network/NFCX0STS">telecommunications network</a>, <a href="/facts/Data_center/DS5wJY41">data center</a> or <a href="/facts/Industrial_control_system/YzgsMy2x">industrial control system</a> from undesirable acts by a malicious insider or inexperienced technician acting alone. MPA requires that a second authorized user approve an action before it is allowed to take place. This pro-actively protects data or systems from an undesirable act. </p>
