Its Time to Think about SharePoint Security
The increasing use of Microsoft SharePoint to store sensitive business data and extend
access and collaboration to partners, customers, and suppliers has outpaced native SharePoint
security capabilities. More and more organizations are storing and accessing sensitive, regulated
information through this platform. To improve business security, organizations must invest in
organizing, managing, and protecting these valuable assets. By implementing the ve lines of
defense outlined in this playbook, you will be able to overcome operational challenges and
protect your SharePoint deployments against both internal and external threats.

Ensure access rights remainaligned with business needs.
CHALLENGE #1
SharePoint Security GapWithout an aggregated, centralized system to view rights
information, SharePoint permissions for each site collection
must rst be extracted to an Excel spreadsheet and then
combined by hand to analyze. And, that analysis must be
done manually within Excel or exported yet again to a
third-party analytics platform.
Unstructured datanow accounts formore than 90% ofthe Digital Universe.

automate the review process to keep rights aligned with business needs.
The Advantage- Understand who has access to what data or, conversely, what data any given

granted, if there are dormant users, and who owns each item and document.
- Help administrators and data owners establish a baseline snapshot of access
rights and conduct rights reviews.
