FINAL WORD Why data classification should drive your security strategy If you haven’t identified what data is sensitive to your business, where it resides and how it’s being used, how can you hope to protect it? Thomas Fischer, Threat Researcher and Global Security Advocate at Digital Guardian, discusses why getting to grips with data should be the first step in any effective security strategy. T here are two types of businesses in the world today: those that run on data and those that will run on data. As a result, data security now sits at the top of nearly every organisation’s priority list. But with such a high volume coming into most businesses every day, how can InfoSec professionals quickly identify which is the highest priority for protection? After all, security costs time and money, and not all types of data are as sensitive or vulnerable as others. Leading analyst firms Gartner and Forrester both say that data classification is foundational to an effective data security programme. Organisations cannot efficiently protect their growing pool of data without a better understanding of what they have and where it is. For channel partners, providing data classification to clients provides a prioritised list of their data assets and enables them to focus the controls on the most important data. This is an essential piece of an organisation’s data security strategy. For compliance-oriented applications, data classification allows compliance teams to understand how regulated data is moving, and where it may be at risk. Better understanding of how the data is being protected leads to more accurate data protection and reduced overheads for InfoSec teams, enabling faster time to value for your clients. 64 What is data classification? Data classification is a process of consistently categorising data based on specific and predefined criteria so that it can be efficiently and effectively protected. In addition to simplifying security strategies, it can greatly assist companies in meeting governance, compliance or regulation mandates such as the Payment Card Industry Data Security Standard (PCI DSS), as well as protecting important intellectual property. How can businesses implement an effective classification strategy? Data classification is not a one-size-fits-all approach. Every business has different needs to address, so a strategy must be tailored accordingly. However, the following five-point action plan can be used to create the foundation of an effective strategy for nearly any business. 1) Define a data classification policy What are the goals, objectives and strategic intent? Make sure users are aware and understand why it’s being put in place. An effective data policy must also balance the confidentiality and privacy of employees/ users against the integrity and availability of the data being protected. A policy that’s too stringent can alienate staff and impede Thomas Fischer, Threat Researcher and Global Security Advocate at Digital Guardian. their ability to carry out their jobs, but if it’s too lax, the very data the business is trying to protect could be at risk. Organisations cannot efficiently protect their growing pool of data without a better understanding of what they have, and where it is. ssue 08 NTELLIGENT TECH CHANNELS
