There are misconceptions about data breaches, their affect, impact, and cost. Don’t allow yourself to think, “We haven’t been breached”, “We won’t get breached”, or “A breach won’t seriously affect us”. The odds are good that you’ve already been breached and don’t know it. What should concern you is whether or not you know what was stolen. Surprisingly, most business owners don’t know what data they are holding that could cost them the most. Nor do they know where their critical data lives, or who has access to it. If you choose not to take a proactive stance on your businesses security, you should at least know what data matters most to your business, where it resides, and who has access to it.
