Read the first 7 Computer Systems & Software Updates flashcards as text

  1. What is the role of a 'patch management policy' in a process plant IT environment?

    Answer: Defining procedures for evaluating, approving, testing, and deploying software patches

    A patch management policy establishes the governance framework ensuring patches are applied systematically and safely.

  2. In the context of industrial control systems, what does 'firmware' refer to?

    Answer: Low-level software embedded in hardware devices such as PLCs and smart transmitters

    Firmware is software programmed into non-volatile memory of hardware devices that controls the device's basic operations.

  3. Which of the following is a key benefit of using a virtualized server environment for process plant historian and HMI servers?

    Answer: Simplifies backup, recovery, and hardware migration through snapshot capabilities

    Virtualization allows entire server states to be snapshotted and restored quickly, greatly simplifying backup and recovery procedures.

  4. A technician needs to transfer a software update file to an isolated OT network. Which method is considered safest?

    Answer: Using a scanned, verified USB drive following a defined media transfer policy

    A scanned and verified removable media transfer with a defined policy maintains the air gap while safely moving the update file.

  5. What is the function of a 'software asset inventory' in process plant operations?

    Answer: Recording all installed software, versions, licenses, and locations to support updates and audits

    A software asset inventory provides a complete record of installed software, enabling accurate patch tracking and license compliance.

  6. Why is it important to synchronize clocks across all devices in a process control network?

    Answer: To ensure accurate event sequencing and alarm timestamp correlation during incident investigation

    Accurate timestamps are critical for reconstructing the sequence of events during process upsets or safety incidents.

  7. Which standard provides cybersecurity guidance specifically tailored to industrial automation and control systems (IACS)?

    Answer: IEC 62443

    IEC 62443 is the international standard series addressing cybersecurity requirements for industrial automation and control systems.
