Short-Range, Low-Power, and Long-Range Networks – CWISA Module 7 Summary
Short-Range, Low-Power, and Long-Range Networks – CWISA Module 7 Summary Wireless IoT networks are built on a balance between speed, range, and power consumption. In CWISA Module 7, we explore the major wireless protocols used in IoT and the trade-offs that define their performance. Understanding these trade-offs is critical for selecting the right technology for…
Wired 802.1X EAP-TLS Full Lab: Aruba CX Switch + ClearPass + Windows Client
Wired 802.1X EAP-TLS Full Lab: Aruba CX Switch + ClearPass + Windows Client Most engineers configure 802.1X on wireless and completely ignore their wired ports and that is a serious security gap. Here is the reality: anyone who walks into your office, plugs a network cable into a switch port, and gets full network access…
Radio Frequency Hardware — CWISA Module 6 Summary
Radio Frequency Hardware — CWISA Module 6 Summary Wireless communication is not only about RF theory — it also depends heavily on hardware components that generate, transmit, receive, and process radio signals. In CWISA Module 6, we explore Radio Frequency Hardware, including antennas, circuit components, link types, and device classifications used in wireless IoT deployments.…
EAP-TLS Wireless Authentication with Aruba ClearPass
EAP-TLS is widely considered the gold standard for wireless authentication. In this post — based on my video walkthrough — I’ll show you exactly how to configure it end-to-end using Aruba ClearPass. In enterprise wireless environments, relying on usernames and passwords for authentication is increasingly risky. Passwords can be stolen, phished, or brute-forced. Certificate-based authentication…
RF Communications – CWISA Module 5 Summary
RF Communications – CWISA Module 5 Summary Understanding Radio Frequency (RF) communication is fundamental for designing and troubleshooting wireless networks. In CWISA Module 5, we explore how RF waves behave, how they are measured, and how they carry data across wireless systems. This knowledge is critical for Wi-Fi, IoT, and wireless security engineers. RF Wave…
Planning Wireless IoT Solutions – CWISA Module 4 Summary
Planning Wireless IoT Solutions – CWISA Module 4 Summary Designing a reliable IoT wireless network is not just about deploying devices — it requires a structured engineering approach that aligns business needs with technical capabilities. In CWISA Module 4, we focus on how to plan wireless IoT solutions by identifying requirements, understanding constraints, and applying…
Wireless IoT Network Use Cases – CWISA Module 3 Summary
Wireless IoT Network Use Cases – CWISA Module 3 Summary Wireless connectivity plays a critical role in enabling the Internet of Things (IoT). In CWISA Module 3, the focus shifts from IoT fundamentals to how wireless networks support real-world IoT deployments across different industries. This module explains the different types of wireless networks based on…
How to Configure Enforcement Profiles in Aruba ClearPass for Dynamic Wireless User Roles
How to Configure Enforcement Profiles in Aruba ClearPass for Dynamic Wireless User Roles Introduction One of the most powerful features in Aruba ClearPass is the ability to dynamically assign user roles to wireless users based on attributes such as department, AD group, or authentication method. In this article, I will demonstrate how to: Create Enforcement…
Aruba ClearPass Role Mapping and Enforcement Policy with Active Directory (Wireless 802.1X)
Aruba ClearPass Role Mapping and Enforcement Policy with Active Directory (Wireless 802.1X) Network Access Control (NAC) is a critical component of modern enterprise security. One of the most widely deployed NAC platforms today is Aruba Networks ClearPass, which enables centralized authentication, authorization, and policy enforcement across wired and wireless networks. In this article, we walk…
CWISA Journey – Module 2 Summary
CWISA Journey – Module 2 Summary The Internet of Things (IoT) In Module 2 of the CWISA syllabus, the focus shifts from general wireless fundamentals to the Internet of Things (IoT) itself. This chapter explains what IoT really means, how it evolved, where it is used, and how IoT systems are structured from sensors to…
