Prior to reading this, please check out a previous blog of ours on how important an external penetration test is.

Hey there, security enthusiasts and curious minds alike! Today, we are taking a deep dive into a topic that’s often buzzing around but isn’t always entirely understood – yes, we’re talking about Internal Penetration Testing (IPT). It’s a phrase that sounds technical, yet it’s vital for the security health of every organization, big or small.

A Quick Introduction

So, what exactly is Internal Penetration Testing? In the simplest terms, it’s like a stress test for your organization’s internal cyber defenses. Imagine a friendly hacker trying to find holes in your security from the inside, before the not-so-friendly ones do. That’s pretty much the essence of IPT!

Inside the Castle Walls

Think of your company as a fortress. Now, most fortresses are designed to keep invaders out, right? They have strong walls, gates, maybe even a moat with a dragon if you’re feeling a bit fantastical. But what happens if the enemy is already inside or if there’s a traitor within the walls? That’s where internal penetration testing shines like the unsung hero of a fantasy saga.

Why Should You Care?

1. Insider Threats: Believe it or not, threats often come from within. It could be an unhappy employee, a careless mistake, or someone with too much access and not enough training.

2. Security Flaws: Every system has weaknesses. IPT helps identify and fix them, strengthening your organization’s internal defenses.

3. Data Protection: IPT ensures that the sensitive data within your organization remains confidential and inaccessible to unauthorized personnel.

Some Common Findings:

1. Over-Generous Permissions

One of the most common issues we uncovered was overly generous file and folder permissions. Some critical files were accessible to almost anyone on the network. Imagine leaving your diary out in the open at a party and expecting people not to read it. Ensuring that only the right people have access to specific files is crucial.

2. Outdated Software

We found several software programs that hadn’t been updated in ages. Outdated software can be a goldmine for hackers since they often contain vulnerabilities that have been fixed in newer versions. It’s like having an old lock that thieves have learned to pick easily.

3. Weak Passwords

You’d be surprised how many times “Password123” or “Admin” can grant someone access. Some employees were using weak passwords or, worse, default ones. It’s akin to securing a treasure chest with a flimsy lock that anyone can break.

4. Unused Accounts

We found multiple old accounts, from former employees or temporary contractors, that were still active. These are like leaving backdoors open; you never know who might have the keys or find a way in.

5. Unencrypted Sensitive Data

Some sensitive data was stored without encryption, meaning if someone accessed it, they could read it as easily as you’re reading this blog post. Encryption jumbles up data, turning it into an unreadable mess without the right decryption key.

The Process Unveiled

So, how does it work? The process is thorough yet non-intrusive. Professional testers simulate cyberattacks on your internal networks and systems, mimicking the strategies of malicious hackers but with a white hat twist – they’re doing it to enhance your security, not breach it.

The Aftermath

Once the test is complete, you’re not left with a bunch of jargon and tech lingo to decipher. Instead, you get a clear, concise report outlining the identified vulnerabilities and actionable steps to fix them. It’s like having a health check-up, where the doctor not only tells you what’s wrong but also advises you on how to get better.


In a world that’s becoming increasingly digital, where data is as precious as gold and cybercriminals are always lurking, internal penetration testing is not just a recommendation – it’s a necessity. It’s the silent guardian that watches over your organization from the inside, ensuring that the walls are as secure as the gates.

Join us next time as we delve deeper into the tools and techniques that make internal penetration testing a cornerstone of modern cybersecurity. Until then, stay curious, stay informed, and most importantly, stay secure!
