The CREST CRT is not a test you cram for in a weekend. It checks whether you can think like a practical tester under time pressure, use common tools well, spot weaknesses methodically, and record what matters. That means your study plan needs more than a list of topics. You need a safe lab, a … Read more
A good pentest report does two jobs at once. It gives technical teams enough detail to reproduce and fix security issues, and it gives managers a clear view of business risk. That balance matters even more when you are working toward a CREST CPSA-style standard, where clarity, evidence, and professional judgment are all part of … Read more
Recon and enumeration are where a CREST CPSA-style assessment is usually won or lost. Not because they are flashy, but because they shape everything that follows. If you miss a subdomain, trust bad DNS data, skip a service banner, or fail to write down what you tested, the rest of the engagement becomes guesswork. A … Read more
The CREST CPSA is not a memory test. It checks whether you can think like a junior penetration tester under time pressure, make sound choices, and explain what you are doing. That is why a good study plan should not be a random list of tools and topics. It should follow the same flow you … Read more
Incident response in industrial control systems is not the same as incident response in regular IT. In a business network, the usual move is often simple: isolate the device, block the traffic, rebuild the host. In an ICS environment, that same action can stop a process, damage equipment, create a safety event, or interrupt a … Read more
IT and OT security often get grouped together, but they do not work under the same rules. In a normal IT environment, the main goal is usually to protect data and keep business systems running. In an industrial environment, the priorities shift. Availability becomes more critical. Safety becomes non-negotiable. And the systems involved are often … Read more
The GIAC GICSP is not a typical IT security exam. It sits at the point where enterprise security meets industrial control systems, operational technology, and safety-critical environments. That changes how you should study. If you come from an IT background, many ideas will feel familiar at first: networks, protocols, hardening, incident response, and risk management. … Read more
A good penetration test report does two jobs at once. It tells a technical team exactly what was found and how to fix it. It also gives managers enough context to decide what to do first. That balance is hard to get right. Many GPEN candidates and junior testers can find issues during an assessment, … Read more
Reconnaissance and enumeration are where a penetration test either becomes methodical or turns into guesswork. In the GPEN context, that difference matters. A repeatable workflow helps you gather the same core facts every time, avoid missing obvious attack paths, and keep your notes useful when you need to explain risk later. A printable checklist is … Read more
Preparing for the GIAC GPEN in 2026 is not just about memorizing tools or collecting notes. The exam tests how you think like a methodical penetration tester. That means moving in a clear order: scope the target, enumerate what matters, choose the right attack path, validate impact, and explain the result in a way a … Read more
