How to Say Goodbye to RC4 While Keeping Your Sanity
The old RC4 encryption protocol has many weaknesses. To help harden attack surfaces, Microsoft is about to roll out updates that change domain controllers’ behavior regarding ticket encryption. Unfortunately, RC4 is still the backbone of many Kerberos implementations. Cue predictions of disruption and IT meltdown for the unprepared.
Don't panic! The doomsday scenarios might be exaggerated, but you still need to address certain configurations before Microsoft makes its next move towards RC4-free Kerberos.
In this webinar, identity expert and Security and PowerShell MVP Evgenij Smirnov walks you through the upcoming changes, shows you how to determine the actual consequences for various configurations found in the field, and offers practical advice on locating and remediating potentially disrupted applications—or even preserving the status quo until your organization can deal with the death of RC4.
