Bottom line: GRAU DATA audits Windows backup repositories in 15 minutes for seven typical vulnerabilities that provide attack surface to ransomware attackers.
The company GRAU DATA from Schwäbisch Gmünd offers a Repository Security Check for Windows to identify configuration errors and security gaps in backup repositories. The procedure can be applied independently of specific products from the vendor.
Backup repositories are targets of ransomware campaigns because attackers deliberately attempt to delete or encrypt backups, thereby preventing the recovery of production systems without ransom payment. The Repository Security Check examines typical Windows configurations in around 15 minutes and is conducted as a consultative discussion with a technical expert.
The audit procedure focuses on seven vulnerabilities: extensive administrative rights on the repository, direct Active Directory integration of the backup server, absence of WORM storage mechanisms (Write Once, Read Many), insufficient network segmentation between backup server, repository and production systems, excessively granted account privileges including local administrator and shared service accounts, lack of monitoring of backup job changes and unauthorized access, and missing regular restore tests.
The offering is aimed at organizations that wish to evaluate their current security status of Windows-based data protection infrastructure. It is usable independently of specific products such as Blocky for Veeam from the vendor.
