Qumulo Launches a Wave of Security Enhancements

Qumulo, the provider of solutions for enterprise file data management across hybrid cloud environments, has announced significantly enhanced security support for network file system protocol NFSv4.1. The company has also announced it has received an attestation of compliance with SOC 2 Type II.

Qumulo introduced Qumulo on Azure as a Service (QaaS) in July of 2021, so that multi-cloud organisations could store, manage, and curate their data with simplicity anywhere. To prove the security of its service across key criteria, Qumulo engaged A-Lign, an independent auditing firm, to review its service data controls. This attestation of compliance with SOC 2 Type II for QaaS provides customers peace of mind that the data entrusted to QaaS will be secured.

With the new enhancements to the NFSv4.1 protocol, there is additional support for authentication via Kerberos and file locking control. In NFSv3, users can impersonate any user with root access to their client machine. Kerberos solves this problem with cryptography techniques to securely authenticate users from a central identity provider, such as Microsoft Active Directory Domain Controllers or an open-source Kerberos Key Distribution Center (KDC).

The latest release includes improved lock handling for file access. When files are accessed by a client, they are locked to ensure that other clients cannot write data to the file, preventing potential corruption or version control issues. NFSv3 had known problems with orphaned sessions leaving files locked, requiring administrators to run a process to release locks from time to time. NFSv4.1 provides superior lock control and time outs to release locked files after some interval of inactivity.
