All in Rules
Today’s adversaries don’t play by any rules. They constantly adapt and learn from failures and the complexity of their tactics and thinking is ever increasing. Whether nation sponsored, criminal or simply opportunistic, this new breed of attacker isn't bogged down trying to exploit the usual suspects (firewalls, web servers, email servers, etc.) They’re not wasting time thinking about your security checklists, policies, and procedures that have been painstakingly developed to thwart them. They’re happy to just go around, under, or over them and uncover weak links wherever possible.
One of the most often exploited weak links is the human one. That human risk can come from both an outsider and insider threats, including your supply chain. The question then becomes, not only whether you know your adversary or not, but do your partners, suppliers and vendors know them as well? Do they know theirs? How frequently are they doing security assessments? It’s a situation that needs frequent testing.
