  • 1Identify the four major types of data threats that compromise information security in networked systems
  • 2Ask learners: 'What happens when Ama sends her exam result via email but her classmate never receives it—what could have gone wrong?' Learners whisper answers to their partner.
  • 3Show three quick scenarios on the projector: (1) Kofi's bank message blocked; (2) Yakubu's password read by someone else; (3) Abena's grade changed to A without her knowing. Learners point to the screen and call out what type of problem each is.
  • UNDERSTANDING THE FOUR MAJOR DATA THREATS
  • 1Play a 3-minute video on YouTube (search: 'data security threats') via projector showing Interruption, Interception, Modification, and Fabrication with real-world examples; pause after each threat and ask learners to write the threat name in their exercise books.
  • 2Display a table on projector with two columns: 'Threat Type' and 'What Happens'. Write Interruption, Interception, Modification, Fabrication in left column. Ask learners to complete right column using the textbook page 87 or Learners Resource Pack section 4.2.
  • 3A volunteer comes to the board and writes a one-sentence definition of Interruption (data blocked before reaching destination). Class repeats the definition chorally three times.
  • APPLYING THREATS TO REAL GHANAIAN SCENARIOS
  • 4Read aloud: 'Sulemana transfers GH₵500 via MoMo to his sister in Bolgatanga, but the message never arrives—Interruption. A hacker reads his PIN while he types—Interception. A thief changes his account balance from GH₵1,000 to GH₵100—Modification. A fraudster creates a fake MoMo confirmation showing he paid when he did not—Fabrication.' Learners pair-check which threat is which on a handout.
  • 5Display four images on projector: (1) broken internet cable; (2) CCTV capturing password entry; (3) hospital record altered; (4) fake Ghana Card. Learners work in groups of three to match each image to Interruption, Interception, Modification, or Fabrication using the Internet connection to research if needed.
  • 6Ask: 'Which threat is most dangerous for a student sharing classwork online?' Learners show fingers 1–5 to rate their confidence in explaining their choice to their partner.
  • 1Computer/Laptop
  • 2Projector
  • 3Textbook (page 87)
  • 4Learners Resource Pack (section 4.2)
  • 5Internet connection
  • 6YouTube video: 'data security threats'
  • 7Printed handout with threat scenarios
  • 8Exercise books
  • 1Learners stand and form four corners of the classroom labelled Interruption, Interception, Modification, Fabrication. Read out a threat scenario (e.g., 'Ama's email blocked by firewall'); learners run to the correct corner and sit.
  • 2Ask: 'Which threat did you find hardest to understand today?' Learners discuss with their neighbour for 30 seconds, then three volunteers share their answer.
Exercise
  • 1Describe in two sentences what Interception means and give one example using a Ghanaian context (e.g., MoMo, bank, school record).
