Tracking High Value Targets
High value targets are resources that would be of great interest to people who should not have access to them.
These might be folders containing compensation information, the email mailbox of the CEO, or the database containing the credit card numbers of your customers. Knowing where that data is stored, used, and transmitted is a critical first step in making sure that you are doing your job as a security professional. Then align your security investments with protecting those high value targets.
Before you go off and undertake a high-priced data classification and discovery project, please speak with your business leaders and get them to tell you what is important and where it is located. Then utilize your existing security tools to track activity to those assets.
Track high value targets with a SIEM. In an ArcSight implementation this can be done with asset categories and active lists. In the unstructured data world, the Varonis DatAdvantage suite gives you the ability to flag and tag these resources so that they can be easily identified, and special reports created to protect them.
Make sure that you have access provisioning and entitlement review processes in place to ensure that you are following a least privilege model. If you have 20 system administrators who have access to the compensation folder, that is a PROBLEM.
Only when you have the basic blocking and tackling in place should you can move up to the advanced class and start talking about data discovery, data classification, and data loss prevention solutions. Focus on what matter to the business! Protect the high value targets.
