One of the biggest challenges in IT security is determining whether the tools and configurations you have in place are giving your organization the level of security you require. Here's how penetration testing can help.

The IT security landscape is a complex maze of technologies, architectures and policies which can be incredibly difficult to navigate. A defense-in-depth strategy consists of any number of security tools working in conjunction to form an overall security posture. One of the biggest challenges is determining whether the tools and configurations you have in place are giving your organization the level of security you require. A penetration test, or pen test, is one way to accomplish this.

The Pentagon recently brought in white-hat hackers through a bounty penetration testing program to help it identify more than 100 security vulnerabilities in its systems. Individuals who could find security problems on Pentagon systems could be awarded up to $15,000 each. Approximately 1,400 hackers participated. It might sound like a lot, but considering the amount of damage security breaches cause these days, it's peanuts compared to letting black hat hackers breach your organization.

Part of a solid data security strategy is understanding what your weaknesses are – and dedicating the right tools and resources to properly shore up any vulnerabilities. It's an endless game of cat and mouse that requires a unique look from the outside-in. This is why penetration tests are so valuable.

Instead of implementing a bug bounty pen test program, most companies opt to hire an external firm well-versed in data security to perform penetration tests. These tests can focus on one specific part of an infrastructure, a specific application, or the network as a whole. Focused penetration tests are valuable when implementing a brand new application, cloud service, or other new feature. For most organizations, though, a pen test which validates a wide range of security tools and policies is where the real value of the practice is discovered.

Simply implementing security tools and walking away isn't good enough anymore. Instead, you need to put your tools through the paces of simulated breaches which mimic real-world scenarios. Doing so will help determine the value of each of your security tools, as well as reveal areas of weakness. And finding out where data security needs to be bolstered is incredibly useful for quickly eliminating high-risk areas where breaches can occur.

There are at least eight good reasons why investing in network-wide penetration testing is money well spent. Once you've reviewed these, tell us about your own pen testing strategy. Is this a practice your organization regularly undertakes? Is it something you've tried and decided you didn't need? Do you focus on a single app or service, or do you apply pen testing across a wide range of security tools? We want to hear from you in the comments section below.
