Attack Vector
The route an attacker uses to get in.
What Attack Vector means
Common vectors are email, exposed remote access, vulnerable web applications, stolen credentials, supplier connections and physical access. Most intrusions begin with one of the first three, which is why effort concentrated there produces the largest reduction in risk.
Why Attack Vector matters for small businesses and nonprofits
Listing your vectors turns security into a finite problem. You can then ask, for each one, what would stop it and what would detect it, rather than trying to secure everything at once.
What to do about Attack Vector
- List your realistic entry points and rate the defences on each
- Close what you do not need, starting with exposed remote access
- Ensure each remaining vector has both a preventive and a detective control
