Book description

Learn how to build a defense program against insider threats

Insiders are not always employees and insider threats are not always intentional.

The common characteristics of insider threat victims.
The typical stages of a malicious attack.
The steps you can take to implement a successful insider threat program.
How to construct a three-tier security culture, encompassing artifacts, values and shared assumptions.

“The author has many, many sound things to say about security culture and practice.”

The insider threat

Every type of organization is vulnerable to insider abuse, errors or malicious attacks. These can impact reputation, operations and profitability, and expose data, harm the organization, or deliver valuable intellectual property into competitors’ hands.

Insiders can be current or former employees, contractors, or other business partners who have been granted authorized access to networks, systems or data, and all of them can bypass security measures through legitimate means.

Prepare for insider threats with the most in-depth guide on the market and build a defense program using international best practice.
