Do you use Security Baselines?

𝗗𝗲𝗳𝗮𝘂𝗹𝘁 → 𝗛𝗮𝗿𝗱𝗲𝗻𝗲𝗱

Real configs. Real fixes. Windows & AD security.

𝗗𝗼 𝘆𝗼𝘂 𝘂𝘀𝗲 𝗦𝗲𝗰𝘂𝗿𝗶𝘁𝘆 𝗕𝗮𝘀𝗲𝗹𝗶𝗻𝗲𝘀? You should. They set a clear, enforceable standard for Windows & AD.

Without baselines you’re either on defaults or on local tweaks—both 𝗹𝗲𝗮𝗱 𝘁𝗼 𝗱𝗿𝗶𝗳𝘁, 𝗶𝗻𝗰𝗼𝗻𝘀𝗶𝘀𝘁𝗲𝗻𝗰𝘆, 𝗮𝗻𝗱 𝗲𝗮𝘀𝘆 𝗼𝗽𝗲𝗻𝗶𝗻𝗴𝘀 for attackers.

𝗪𝗵𝗮𝘁 “𝗦𝗲𝗰𝘂𝗿𝗶𝘁𝘆 𝗕𝗮𝘀𝗲𝗹𝗶𝗻𝗲𝘀” 𝗮𝗿𝗲:

A curated set of 300+ GPO settings for domain controllers, servers, and workstations.

𝗪𝗵𝗮𝘁 𝘁𝗵𝗲𝘆 𝗱𝗼 (𝗲𝘅𝗮𝗺𝗽𝗹𝗲𝘀)

🔹 Prefer modern crypto (e.g., Kerberos AES-only; disable RC4).

🔹 Disable legacy protocols/features (e.g., SMBv1).

🔹 Enforce TLS 1.2+ (1.3 where supported).

🔹 Apply privacy and service hardening defaults at scale.

𝗪𝗵𝘆 𝗺𝗮𝗻𝘆 𝘁𝗲𝗮𝗺𝘀 𝘀𝗸𝗶𝗽 𝘁𝗵𝗲𝗺:

In 10+ year environments, some apps still depend on legacy settings—so a straight switch can break things 🧨. You need to phase the rollout.

𝗛𝗼𝘄 𝘁𝗼 𝗮𝗽𝗽𝗿𝗼𝗮𝗰𝗵 𝗶𝘁:

1️⃣ Download the Microsoft baseline for your OS (I have my own stricter Security Baselines as part of my course)

2️⃣ Use Policy Analyzer to compare current state vs. target.

3️⃣ Roll out in stages, monitor impact, and adjust.
