Logical control

Logical control -

Logical controls, sometimes called technical controls, are those   that   protect the systems, networks, and environments that process, transmit and store our data.  Logical controls can include items such as passwords, encryption, logical access controls, firewalls, and intrusion detection systems. Logical controls enable us, in a logical sense, to prevent unauthorized activities from taking place.  If our logical controls are implemented properly and are successful an attacker or unauthorized user cannot access our applications and data without subverting the controls that we have in place.
