From 2abe5b56316998b61ee22f8f1603df1945fbe2c2 Mon Sep 17 00:00:00 2001 From: chmod777Alex <59450257+alexegorov1@users.noreply.github.com> Date: Thu, 24 Apr 2025 15:35:12 -0400 Subject: [PATCH] Update README.md (#10566) Updated the file with 3 more new questions and answers related to segmentation. The original section lacked depth in real-world application. These additions provide practical, security-relevant context that benefits both developers and architects working with dynamic infrastructure. This PR follows the existing structure and tone of the README for seamless integration. --- topics/security/README.md | 28 ++++++++++++++++++++++++++++ 1 file changed, 28 insertions(+) diff --git a/topics/security/README.md b/topics/security/README.md index a4eb9fb..f1d151f 100644 --- a/topics/security/README.md +++ b/topics/security/README.md @@ -640,3 +640,31 @@ You can’t.

+What are ephemeral environments in the context of Microsegmentation?
+ +- These are short-lived resources like containers or serverless functions that start and stop quickly. +- Because they don’t last long, they need security rules that can change just as fast. +- Microsegmentation helps by giving each one exactly the network access it needs — nothing more. + +
+ +
+How does Microsegmentation help prevent lateral movement?
+ +- It sets tight rules for how services or systems can talk to each other. +- If one system gets hacked, the attacker can’t easily move to others. +- By dividing systems into smaller zones, it makes the whole network harder to break into. + +
+ +
+What challenges arise when scaling Microsegmentation?
+ +- As more systems get added, managing all the rules becomes harder. +- It’s tough to keep security rules consistent when everything’s changing all the time. +- You also have to be careful not to slow things down while keeping everything secure. + +
