🧒 Erkläre es wie einem 5-Jährigen
Imagine you have a security guard at your front gate, another in your kitchen, and another in your backyard. Normally, they don't talk. A thief might distract the gate guard to sneak past the backyard guard. XDR is like giving them all walkie-talkies. As soon as one guard sees something suspicious, everyone knows, and they can catch the thief together.
🤓 Expert Deep Dive
Technically, XDR is a move away from 'Siloed Security'. While EDR focuses on the 'Endpoint', XDR ingests data from 'Identity' (AD/LDAP), 'Network' (NDR), 'Email', and 'Cloud Workloads'. It uses Machine Learning to deduplicate alerts and build a 'Timeline' of an attack. This drastically reduces 'MTTR' (Mean Time to Respond). For instance, an XDR playbook can automatically revoke a user's session in Office 365 the moment an EDR detects a Mimikatz execution on their device. Most vendors offer either 'Native XDR' (all tools from one vendor) or 'Open XDR' (integrating tools from many different vendors via APIs).
