Numerous studies have revealed that insider threats are one of the biggest cause for security attacks. They can go undetected for years as it is hard to distinguish harmful actions from regular work.
To prevent the occurrence of insider attacks, implement the principle of least privileges. Grant users access to only those systems and data that pertain to their job. Maintain a quick reference sheet for all access lists on your file servers.
Learn more on how to granularly manage share permissions with group- or OU-based access restrictions.
Admins need to have complete visibility of share and folder permissions and permissions inheritance. They also require the capability to drill down to granular details to ensure total security of their organization.
Compliance standards like GDPR, GLBA, PCI, DSS, and more require comprehensive auditing of access and share permissions. Often, reports of file share permissions granted to specific groups or a particular user come in handy for IT auditing.
Learn more on how to generate reports on access permissions of all NTFS folders, files, and ensure compliance to IT standards.
Often permissions are set too broadly, like access to an entire file server instead of a specific file or folder -- much to the delight of hackers and internal data thieves. Admins are generally not equipped to track the changing roles of users, organizational changes that modify group authorizations, and job terminations.
Rather than working on an ad-hoc basis, it’s important to have a foundational policy that specifies to who, how and within what time-frame should share permissions be granted.
Learn more on how to monitor critical accounts and their access permissions; assist in root cause analysis with provisions to search ACEs, and modify or instantaneously revoke all permissions in case of a data leak.
Users are often tempted to act on opportunities to swindle business critical data when given access over an unrestricted time frame.
Folder owners can create workflow requests to share folders and files with permissions that range from full control to simply listing the folder’s contents over a designated time frame. Active Directory administrators can then process all these requests, and approve or reject from a single dashboard.
Learn more on how to configure time-restricted file/folder sharing, eliminating the need to revisit the permission settings to extend or rollback the sharing of resources.
