One of the most frequent questions readers ask is:
“What is the difference between Cymulate’s XSPM Platform and pen testing?”
It’s a good question that deserves a detailed answer, so let’s dive into it!
Spelling Things Out
First, it is necessary to define the terminology in use here. Pen testing is a human-driven offensive test that attempts to achieve a specific goal.
That goal might be capturing a specific system or removing a particular file or set of files. Whatever the goal, the pen test’s purpose is to achieve that goal. It is human-driven because the test may encounter circumstances that require non-linear thinking, where the direct path is not the right path. An experienced pen-tester can shift and pivot at each step along the way – sometimes mid-step – and adapt techniques to reach the stated goal. This leads to a curious pattern: once a pen-tester overcomes a security control, they’re not performing all the other potential attacks they could have used – they’ve already overcome the control and then move on.
The other hallmark of a pen test is that Rules of Engagement (ROE) are absolutely necessary to ensure that business operations are not disrupted, and no vital data is put at risk. Since a pen-tester may take paths that carry significant risks in pursuing their goal, knowing what is fair game – and what is off-limits – is critical to ensuring the test doesn’t do more harm than good.
Extended Security Posture Management (XSPM) is designed to validate the efficacy of security controls. Instead of attempting to reach a specific goal, XSPM instead runs hundreds or thousands of simulation operations to map out the strengths and weaknesses of a set of security controls – such as endpoint defensive solutions or email gateway defenses, etc. Each layer of security is tested in-depth, and while the ability to look across layers of controls most definitely exists in XSPM, the goal is a validation of the controls, not the pursuit of a targeted goal.
XSPM is also designed from the ground up to be non-disruptive and non-destructive, removing the need for ROE without incurring risk to the systems, users, or data of the organization. This way, more systems can be tested, and tested more often, since this doesn’t increase risk or put the business in jeopardy of being offline, and requires minimal resources.
It’s Not Either/Or
One of the most common mistakes made by organizations is to think that one methodology removes the need for the other.
Both XSPM and pen testing have value in a robust cybersecurity operation, and neither should be passed over in favor of the other. The reason is simple, the two methodologies are designed to do different things, and both are critical for knowing how to defend the organization against attacks.
Imagine you are a burglar attempting to steal something from a house. A thief would attempt to force the door open and, if that worked, would move on to try getting past the burglar alarm. If the door did not work, they would attempt entry via a window, and so on. The point here is that the first weakness in home security that works is the one they use as their goal is to steal whatever they are after.
A security contractor, conversely, would attempt to map out all the strengths and weaknesses of the house as a whole. Checking each door, window, storm cellar, a secret tunnel, porch entry, crawlspace, etc. The goal is not to steal but to define all the ways that someone could be successful in the attempt to get into the house to see where gaps exist in the house security.
Both types of operations can tell you a great deal about the overall security of the house. Both can also be used to cross-verify each other – the contractor may say a door is strong, but the thief might know how to pick that particular type of lock easily. Alone, you would have trouble getting the entire picture, but together you know that the house is protected.
In the same way, using both XSPM and pen-testing together can allow you to know the complete state of your cybersecurity. XSPM maps out the strengths and gaps of each layer of security controls, while pen-testing along allowed paths (the ROE) allows you to truly battle-test where those gaps may line up to give an attacker an avenue of entry to a specific goal.
There is another reason to use both methodologies – preparation for future events. XSPM can show you where gaps exist in any given set of security controls, even if those gaps cannot be actively used by an attacker at the current time. For example, a weakness in endpoint security may be compensated for by a strong defense at the network layer and, as such, may never be used by a pen-tester. That situation can change, however. If a new vulnerability is discovered in the networking security controls, that weakness that was unusable by a pen-tester today can suddenly become a huge problem tomorrow; and more to the point, a huge problem during the next pen-test if it isn’t addressed before that point.
Timing is Everything
While both methodologies are critical for overall cybersecurity, their schedules are vastly different. Pen-testing is a point-in-time operation, usually done once or twice per year. The reasons for this are the need to map out the ROE, along with the highly specialized training and experience a pen-tester must have – after all, with a limited number of experienced professionals, there are only so many tests they can do in a given amount of time. XSPM is designed to be used continually. When configured well, you could have simulations of different layers of security across different environments, which result in there being a simulation occurring at any given time of any day of any month – ensuring true continuous assessment of the organization as a whole.
Because of differences in when these methodologies are performed, using just pen testing once a year leaves you with no visibility as to the effectiveness of your security controls the other 11 months of the year. Using both methodologies increases your visibility dramatically, allowing you to take action should any new vulnerabilities or concerns arise.
Better Together for Better Security
Cymulate’s XSPM platform gives you ongoing visibility into the strengths and gaps of the security controls throughout your organization. Pen testing provides directed confirmation that the controls work together properly – even when an attacker can change direction and strategy in the middle of the attack. Together, you can manage any gaps, ensure that an attacker would be derailed, and have the documentation to prove it should the need arise.
Cymulate is continuously developing the XSPM platform – for example, in the near future, it will be possible to project potential attack paths using the dataset created by assessments across different environments and security control sets. That being said, until AI advances to the point where an automated system can safely perform potentially destructive operations while still holding to a set of Rules of Engagement, the need for both XSPM and pen-testing will ensure that using both methodologies is going to be the gold standard for some time to come.
