The whole point of a BI system is to give people better access to information and get the right information to the right people at the right time BI systems often bring together data from separate systems The data might be stored in a different fashion for speed of retrieval Changes to the data might include demoralization, aggregation, and cleansing processes These factors provide some interesting challenges to the BI administrator in terms of security In fact, often the desires of the information consumers seem to be at odds with the mandates of the people charged with protecting the data However, with an effective BI tool, you can provide easier access to data while still maintaining the necessary security for that data To look at some of these challenges, consider an example of a school district and some of the challenges such an organization might face while deploying a BI system Why a school district First, it s something a little different from the typical example of protecting credit card information or financial information Second, I ve worked with a number of school districts and have seen the interesting security challenges that they encounter as they try to create data warehouses, longitudinal data systems (systems that track students across multiple schools over multiple years), and No Child Left Behind reporting systems Third, if you are reading this, you have likely been to school and have a basic familiarity with the concepts discussed Finally, the same issues challenging school districts in securing a BI system can be applied to a number of other industries

One of the first interesting challenges you ll encounter when securing a BI system concerns the types of users Again, a goal of a BI system is to give more people access to the information they need The people seeing the data are no longer just the people who key in the data In fact, there are many more information consumers than producers Let s look at our school district example A school district has a number of information consumers: superintendents, school board members, local government, state school boards and governments, the federal government, administrators, research departments, principals, teachers, guidance counselors, parents, students, and tax-paying citizens This list includes an incredibly diverse set of users: from public users to internal users, from very technical users to nontechnical users, and from highly privileged users to restricted users The research department, for example, will often have access to large amounts of data, and potentially sensitive data, often combining demographic information with performance Students or parents might be accessing the same data warehouse or BI system, but their information will normally be limited to their own data at the detail level (the student s own standardized test results, for example) and all data at the aggregate level (how a child s school performs compared to other schools in the district) Each type of user must be carefully evaluated, and significant care must be taken to make sure they are given access only to the type of data they should see

Another security challenge lies in the fundamental difference between a BI system and the transactional systems that feed the warehouse of the BI system Security in transactional systems is often determined by the business process that the transactional system was designed to address

For example, if you have a grade entry system, it s fairly easy to define security requirements Here s a simple list of requirements to start with: Only teachers can enter grades Teachers can enter grades for their students only Grades can be entered only at certain times

Obviously, some special cases would need to be addressed, but by and large the requirements are fairly straightforward When you consider grades in the context of a data warehouse, things get much more complicated Many different types of users are now going after the same information, and different users will have different security requirements Students want to see details of their grades and possibly class averages Teachers may look across years Principals may compare different teachers of the same subject Research analysts may be investigating whether the lottery-sponsored scholarship program has impacted grade inflation across the state Also, grade entry is always done at the detail level (this student got this particular grade on this particular exam on this date); however, grade analysis can be done at multiple levels What started as a simple security problem of entering grades has become exponentially more complex when we start looking at the data for reporting purposes As you can tell from these examples, one of the keys to implementing robust security successfully within in a BI system is flexibility For a transactional system, the security requirements are often easily defined and fairly static; you know exactly who can do what to the data and that normally doesn t change In a BI system, this just isn t true Lots of different groups will all be trying to access the same information, and each group will need to have its own security policy in place In addition, you ll typically see things change significantly over time Special projects, new requirements, and changing environments will necessitate changes in the user population and what type of access they need One last difference between transactional system and BI systems is that transactional systems require read-write permissions and BI systems are generally read-only At first, this seems like a simple case of selecting the proper user profile, as we discussed in 1 In reality, putting a read-only policy in place for users of a BI system is only the first step The question is more about what data users can see than it is about read-write versus read-only access Ensuring that users see only data they are supposed to see is the focus of this chapter and the next
