Penetration Testing – Stories from the Field by William Suthers

William gets to the point of what a pen test should do for your business and how to avoid costly mistakes. 

A penetration test is a service to the client – not an ego trip 

Some pen testers try to validate themselves by trying to ‘break-in’ and thus proving that they are smarter than the defenders. So, let’s be clear – this is not a competition. Our job is to provide our clients with information and support improvement.   In combination we will be stronger. 

We all know who the enemies are – we must work together to defeat them. Never underestimate the creativity of a desperate adversary. 

“It's fun to watch him (William) take apart a network and decide where those vulnerabilities are and then what I can do on the front end to help them.” – Rick Folkerts, Principal Security Analyst, Truvantis 

We believe a penetration test simulates real world adversaries, using the same Tactics, Techniques, and Procedures (TTPs) as them. The results inform your risk assessment process which results in 

  • Remediation 
  • Preventative Control Improvements 

To defend against real attackers, look at your attack surface through their lens. Have your pen tester research you through OSINT in the Surface, Deep & Dark webs to see what attackers can see. 

Vulnerability Assessments, Penetration Tests and Red Teaming are Distinctly Different Tests 

“Pen Testing Features the Use of Human Cunning” – Andy Cottrell, CEO Truvantis 

Seven Ways to (Not) Waste Money on Pen Testing 

Seven common mistakes we see in the field and what you should do about it. 

Mistake One: Compliance ‘only’ Driven Scoping 

What You Should Do – Research, Test and Discover Your True Attack Surface. 

Scope should not be used as a defensive mechanism; it is an enhancing mechanism, used to inform the risk assessment. 

Mistake Two: Only Testing ‘Exposed’ or ‘High-Risk’ Areas 

What You Should Do – Test the Easiest Route and Every Foothold From There. 

Mistake Three: Using Only Internal Controls to Define Attack Surface 

What You Should Do - Research, Test and Discover Stuff You Didn’t Know About Including Shadow IT. 

Mistake Four: Pen Testing Before Standing up a Vulnerability and Patch Management Program 

What You Should Do – Stand up Your Vulnerability Patch Management Program Before Pen Testing. 

Mistake Five: A Pen Test Driven Security Program 

What You Should Do - A pen test is an exercise in depth, not breadth. Take a broad view and consider all of your weaknesses. 

Mistake Six: Remediating Findings Without Remediating Root-cause 

What You Should Do – Address the Root Cause or the Symptom Will Come Back. 

Mistake Seven: Performing Pen Tests That Only Output Findings 

What You Should Do – Create an Action Plan to Inform the Risk Assessment and Address Vulnerabilities. Then, Execute the Plan.
