No Safe Harbor

The Inside Truth about Cybercrime—and How To Protect Your Business

Mark Sangster

Stories of massive data breaches litter the twenty-four-hour newsday headlines. Hackers and cybercrime syndicates are hitting a who’s who of banks, retailers, law firms, and health care organizations: companies with sophisticated security systems designed to stop crime before it starts. Not only that, they’re also attacking companies that thought they were too small to matter. So how do cybercriminals continue to breach the defenses of the big companies—and why do they go after the small ones? And, most importantly, how can companies of all sizes protect themselves?

Cybersecurity expert Mark Sangster deftly weaves together real-life cases in a thrilling narrative that illustrates the human complexities behind the scenes that can lead to companies throwing their digital front doors open to criminals. Within a security context, deep social engineering is the newest and biggest means of breaching our systems. Sangster shows readers that cybersecurity is not an IT problem to solve—it is a business risk to manage. Organizations need to shift the security discussion away from technology gates alone toward a focus on leadership, team behaviors, and mutual support. Sangster punctuates his eye-opening narratives with sets of questions businesspeople at all levels need to ask themselves, facts they need to know, and principles they need to follow to keep their companies secure.
