Welcome to Certified: The CompTIA SecOT+ Audio Course
Security alerts don’t wait for you to feel ready. If you want to work in security operations—or level up in the SOC—this is your audio-first path. Certified: The CompT...
Episode 1 — Decode the SecOT+ SOT-001 Blueprint, Scoring, Policies, and Question Styles
This episode explains how to read the SecOT+ SOT-001 exam blueprint as a set of measurable outcomes, so you can study what the exam tests instead of what feels familia...
Episode 2 — Execute a Spoken Study Plan and Exam-Day Mental Model for SecOT+ Success
This episode teaches a practical, repeatable study plan designed for learners who need consistency more than marathon sessions, with an emphasis on speaking concepts o...
Episode 3 — Apply OT Jobsite Safety: Hazards, PPE, and Lockout/Tagout Done Right
This episode focuses on jobsite safety as a foundational OT security competency, because unsafe work can turn a minor cyber issue into an injury, outage, or environmen...
Episode 4 — Run a Job Safety Analysis in OT: Briefings, Outbriefs, and Safe Work Controls
This episode explains how a Job Safety Analysis (JSA) functions as a pre-task risk assessment that is tightly aligned with OT realities, where conditions can change qu...
Episode 5 — Explain OT Versus IT: Convergence, Responsibilities, and Operational Constraints
This episode clarifies how OT differs from IT in goals, risks, and acceptable change, which is a frequent source of trickiness in security decision questions. You’ll d...
Episode 6 — Identify OT Device Roles: Sensors, Actuators, Controllers, PLCs, HMIs, and RTUs
This episode builds a clean mental map of common OT device roles so you can identify what a device does, what it trusts, and what happens when it fails or is manipula...
Episode 7 — Classify OT Workstations and Data Systems: Engineers, Operators, Historians, Portables
This episode explains the workstation and data-system ecosystem around control devices, because many OT compromises and misconfigurations originate in these “supportin...
Episode 8 — Distinguish ICS System Types: DCS, SCADA, SIS, MES, and Localized Control Networks
This episode teaches the differences among major ICS system types so you can correctly reason about architecture, responsibility, and risk when the exam presents a mix...
Episode 9 — Recognize Stand-Alone Systems and Networks Across Critical Infrastructure Sectors
This episode focuses on stand-alone OT systems and isolated networks, because “air gapped” is not the same as “safe,” and the exam often tests that nuance. You’ll lear...
Episode 10 — Explain Control Logic Foundations: Ladder Logic, FBD, Structured Text, and SFC
This episode introduces control logic languages and representations at a level that supports security and troubleshooting decisions without turning you into a controls...
Episode 11 — Master Process Variables and Set Points: How Control Loops Behave Under Stress
This episode explains how process variables, set points, and basic control loop behavior shape both safe operations and the kinds of troubleshooting decisions SecOT+ q...
Episode 12 — Track I/Os, Watchdogs, Timers, Current Values, and Tags Without Confusion
This episode teaches the practical vocabulary and mental model needed to interpret I/O points, tags, and runtime indicators without getting lost in vendor-specific nam...
Episode 13 — Work with Serial OT Communications: RS-232, RS-485, and Practical Limitations
This episode focuses on serial communications because many critical systems still rely on it, and SecOT+ questions often test whether you understand the operational tr...
Episode 14 — Secure Serial Protocol Reality: Modbus RTU, Profibus, Data Highway Plus, and DNP3
This episode teaches how common serial protocols behave in the real world, and why security decisions in OT frequently start with understanding what the protocol can a...
Episode 15 — Engineer Ethernet OT Communications: EtherCAT, Modbus TCP, and CIP/EtherNet/IP
This episode explains why Ethernet in OT is not “just networking,” and how industrial Ethernet protocols bring timing, topology, and failure-mode assumptions that infl...
Episode 16 — Use OPC DA and OPC UA Safely: Data Exchange, Trust, and Interoperability
This episode teaches OPC as a common interoperability layer that can simplify integration while also creating trust dependencies that the SecOT+ exam expects you to re...
Episode 17 — Handle Building Automation Networks: BACnet, KNX, and Profinet in Mixed Environments
This episode explains why building automation and industrial automation frequently overlap in modern facilities, and how that overlap creates security and operational ...
Episode 18 — Operate OT Wireless Reliably: VHF, AIS, VSAT, M-Bus, 802.15.4, and 802.11
This episode teaches the practical realities of wireless in OT, where reliability, coverage, and interference management can be as important as classic confidentiality...
Episode 19 — Compare Legacy OT Constraints: Embedded, Proprietary, RTOS, and General-Purpose OSs
This episode explains why legacy OT platforms behave differently from modern IT endpoints, and how those differences change what “reasonable security” looks like on t...
