GridGain 8.5.9 Release Notes
What’s New in This Release
Introduction
This release includes one new feature — Snapshot Security — and several bug fixes.
New Feature: Snapshot Security
Snapshot Security helps ensure the integrity of each snapshot file and the overall snapshot process.
When enabled, Snapshot Security provides an additional layer of security, protecting data from modification and corruption and from snapshot file version mismatch. It helps eliminate the possibility of accidentally using files from multiple versions of snapshots. For example, suppose you have 2 snapshots: A and B. It may be possible to accidentally use file1.dat and file 2.dat from Snapshot A, and file3.dat from snapshot B by mistake.
Snapshot Security creates a file registry that contains a list of all of the files included in the snapshot, and their cryptographic hashes. Before being restored, snapshots are compared against this registry to ensure they contain the proper files.
Snapshot Security protects files from substitution; however, it does not protect against malicious actions by hackers/etc.
Enable Snapshot Security via the GG_SNAPSHOT_SECURITY_LEVEL
system property.
Parameter | Description |
---|---|
DISABLED |
Snapshot file registry is not created and never validated if present (default). |
IGNORE_EXISTING |
Snapshot file registry is included in new snapshots. Existing file registries in snapshots are not verified. |
IGNORE_MISSING |
Snapshot file registry is included in new snapshots. Existing file registries in snapshots DO GET verified. Missing file registries in snapshots are tolerated. |
REQUIRE |
Snapshot file registry is included in new snapshots. Presence and validity of file registries in all snapshots are required. |
