How can I implement a Zero Trust Architecture to prevent Lateral Movement in a hybrid network?

All answers to this question.

Implementing Zero Trust requires moving away from the "castle and moat" mentality. You should start by implementing Micro-segmentation at the workload level. By using software-defined networking (SDN), you can create granular policies that only allow specific applications to communicate with one another (e.g., the Web Tier can talk to the App Tier, but not directly to the Database). Additionally, integrate Identity Intelligence to verify the "health" of the device and the user's behavior in real-time. If a user suddenly tries to access an RDP port from a new location, the system should automatically step up authentication or block the connection entirely, regardless of their credentials.

Have you audited your current Service Accounts to see if they have excessive permissions that could be exploited for privilege escalation during a breach?

• Michael, that is a critical point. Many organizations focus so much on human users that they forget about the "non-human" identities. Service accounts often have static passwords and broad access, making them a goldmine for attackers. I’ve found that implementing a "Just-In-Time" (JIT) access model for these accounts drastically reduces risk. By granting permissions only for the duration of a specific task and then revoking them, you eliminate the "standing privileges" that attackers rely on to move laterally through your data center environment.

I recommend using a "Honeytoken" strategy. Place fake credentials in your memory or files; if they are used, you get an immediate high-fidelity alert of a breach.

• I completely agree with Jennifer. Deception technology like Honeytokens is one of the few ways to catch a sophisticated attacker who is already "living off the land" inside your network.
