Global Outage Caused by Software Glitch, Says SentinelOne
By Netvora Tech News
SentinelOne, a leading cybersecurity company, has attributed a recent global outage to a software bug. The incident, which occurred last week, affected various services and prevented security teams from accessing critical data and management consoles. While endpoints remained secure, the company says the outage had a significant impact on its ability to manage security operations.
Causes of the Outage
The primary cause of the outage was a software glitch in SentinelOne's infrastructure control system, which removed essential network routes. This resulted in a widespread loss of network connectivity within the SentinelOne platform.
The company explains that the removal of the important network routes and DNS resolver rules occurred after an outdated control system was triggered by the creation of a new account. The software bug in the configuration comparison function caused the current system configuration, including all network settings, to be overwritten.
The decommissioned system no longer possessed the actual network configurations, resulting in an empty route table being restored.
The outage had a significant impact on SentinelOne's services, with the majority of its offerings unavailable for hours. The company's production systems are currently being migrated to a new cloud architecture.
- Multiple services were affected, including the management console and related services.
- Security teams were unable to access critical data and management consoles, hindering their ability to manage security operations.
SentinelOne has taken measures to prevent similar incidents from occurring in the future. The company has implemented changes to ensure that decommissioned code cannot be triggered during the migration to the new cloud architecture.
The company has also taken steps to improve its infrastructure control system and configuration comparison function to prevent similar software glitches.
