Note: Today is week 2 of a 9-week blog series in which we are peeling back the 7 Layers of Data Security. By taking this journey, you are making long strides toward building a culture of security that will endure for years, weather future challenges, and meet every compliance and regulatory requirement you face.  Read the first post.

Mission-Critical Assets are the devices, applications, and databases that makeup the crux of your business. Without them, your company could not operate. So it makes sense that your security strategy is built in layers, each performing a different function in protecting your Mission-Critical Assets.

The term "Mission-Critical Assets" makes it sound like your business is of strategic significance in a military operation. In a very real sense, this analogy is appropriate. Malicious forces on multiple fronts are confronting your business every day. What they're after differs from attack to attack. As a business leader, however, your job is to protect your Mission-Critical Assets.

Examples of Mission-Critical Assets

Healthcare

  • Electronic Medical Record (EMR) software

Engineering

  • Auto CAD software
  • Database of schematics

Manufacturing

  • OS for manufacturing equipment

Financial Services

  • Customer financial records

Cloud and IT Services Companies

  • Central network and database environment
  • Ticket management software for support requests

There is no one-size-fits-all approach to securing those assets because every business' network and important assets are different. However, knowing what technology is at the core of your business allows you to prioritize how you begin to secure that technology. So, all security conversations must begin there.

"If companies don't know what data they have and how to categorize it, they tend to value everything as imperative, just in case. When you're deciding how best to protect your data and applications, the key to success lies in identifying what's mission-critical — that is, what your business can't live without."

Make a List

To determine what are your company's Mission-Critical Assets, complete the following sentences in your own words:

  • Without access to _____________­­_______, my employees could not do their jobs.
  • If _____________­­_______ was not functioning, my business would not make money.
  • If the database of my company's _____________­­_______ was compromised, released to the public, stolen, it would be very, very bad.

Using this framework, make a list of an many Mission-Critical Assets as you can think of.

While you likely already had a good picture of what technology resources are most important to your organization, getting them in writing is a necessary first step in establishing a security strategy.

With these assets documented, we can begin to outline how to protect them.

Layer 1: Perimeter Security

The first line of defense around Mission-Critical Assets in any environment is called "Perimeter Security." We discuss how it is  the demarcation between you and third parties here.
