Executive support can make or break any program within your organization (security-related or otherwise). No support means no budget, no resources, no prioritization. In other words: no program.
Security awareness training specifically can have its own set of hurdles. Cybersecurity programs
have traditionally focused on software solutions designed to prevent, protect, detect, and respond to attacks. With security awareness training – a very human aspect of your cybersecurity program – the lack of executive support will likely be the deciding factor as to whether it is implemented or not.
