Microsoft has released out-of-band updates to address authentication failures related to Kerberos delegation scenarios impacting Domain Controllers running supported versions of Windows Server. These issues affect systems running Windows Server 2019 and lower versions, including Windows Server 2016, Windows Server 2012 R2, Windows Server 2012, Windows Server 2008 R2 SP1, and Windows Server 2008 SP2. The emergency updates address "a known issue that might cause authentication failures related to Kerberos tickets you acquired from Service for User to Self," a Microsoft announcement explained on Sunday.
What does system hardening encompass? Let's take server hardening as an example. While the former focus on pointing out configuration drift from specific compliance frameworks, and the latter can do that as well as enforcing hardening policies/configuration changes, they don't provide a solution for the entire hardening process like their CalCom Hardening Suite does.
Hackers stayed hidden for nine months on a server holding customer information for a Queensland water supplier, illustrating the need of better cyberdefenses for critical infrastructure. SunWater is Australian government-owned water supplier responsible for operating 19 major dams, 80 pumping stations, and 1,600 miles long pipelines.
