The emergence of Advanced Persistent Threats (APTs), zero-day vulnerability exploits, and the ever-present threat posed by arguably the most dangerous of adversaries, the organization’s own users, continue to poke new holes in even the most well-laid security architectures. While the tools that attempt to keep data and other assets safe are doing their best to keep pace, malicious software, and the people behind it, continue to find ways to avoid detection by, circumvent, or even subvert an organization’s perimeter and endpoint defenses.
