Forward-Leaning Security: How to Think Like an Attacker—Without Being One

Most businesses are still securing yesterday’s threats.

They’re responding to compliance demands. They’re reacting to the last phishing email. They’re deploying the tools their vendor recommended.

But attackers aren’t waiting. They’re probing. Right now. Right this second. Looking for the open port, the privileged account, the misconfigured access.

If you want to stay ahead, you need to think like an attacker—without being one.

That means reducing opportunity before someone exploits it. It means engineering your posture to limit what damage can be done, not just hoping to detect it after the fact.

Here’s how forward-leaning teams do it.

1. Shrink What They Can See

Attackers don’t hack everything—they scan everything. And then they focus on what’s exposed.

Your job is to shrink your visible footprint:

• Close unused ports and remote services

• Hide systems from internet-facing discovery tools

• Use application allowlisting to stop code before it runs

If they can’t find it, they can’t target it.

ThreatLocker Tip: Application Allowlisting + Network Control policies let you block all unknown software and restrict access between devices—even on internal networks.

2. Kill “Default Admin Access” for Good

Attackers don’t need to break in. They just need to land somewhere with too much privilege.

Remove:

• Local admin rights for end users

• Shared credentials across systems

• “Temporary” elevated access that never got removed

The more access you have to clean up during an incident, the longer you stay exposed.

ThreatLocker Tip: Use Elevation Control to grant privilege only to approved apps—no need to give users blanket admin access ever again.

3. Fence in What Is Allowed

Even legitimate apps can be turned into tools for attackers.

We’ve seen:

• PowerShell used to launch ransomware

• Excel macros used to exfiltrate data

• PDF readers used to download malicious payloads

Don’t just trust applications—contain them.

ThreatLocker Tip: Ringfencing restricts what apps can touch—even if they’re trusted.

4. Block the "First Click" Path

Most attacks don’t need zero-days. They need someone to click something.

A single bad download can lead to:

• Ransomware

• Keyloggers

• Lateral movement across your entire environment

Solution: Make that first step impossible.

• Block downloads from untrusted browsers

• Prevent software from launching unless approved

• Cut off paths to internal tools from unknown apps

ThreatLocker Tip: Default deny + policy enforcement = no execution without permission.

5. Run One Internal Red Team Drill

You don’t need a penetration test firm. Just simulate one action:

• Can a non-IT user install software?

• Can they access sensitive folders?

• Can they move between devices with a shared password?

If the answer is yes—so can an attacker.

Security Isn’t Passive Anymore

You don’t have to become a hacker. But if you want to stay ahead, you do need to think like one.

Every open port, unscoped policy, or “temporary” privilege is a door they’ll walk through—unless you lock it first.
