Allow Listing vs Blacklisting (Which Is Better?)
There are two main ways to control what runs on your systems.
✅ Blacklisting (Most Common)
Blocks known bad programs.
Works well… until something new shows up.
Which happens constantly.
✅ Allow Listing (Stronger)
Only approved programs can run.
If it’s not on the list—it doesn’t open. Period.
👉 Real-World Comparison:
- Blacklisting = “We block the bad stuff we recognize”
- Allow Listing = “If we didn’t approve it, it doesn’t exist”
⚠️ The Catch
Allow listing is stricter.
Sometimes something legit won’t run until it’s approved.
