This vs That

This topic is often confused with the topic of network security. However, while network security focuses on protecting the network infrastructure, cybersecurity: common attacks — phishing, ransomware, SQL injection, social engineering focuses on protecting sensitive data and systems from cyber threats.

Time-Saver Hack

A valid shortcut for this topic is to remember the acronym "PHISH" to help identify the different types of phishing attacks: - P: Phishing - H: Hacking - I: Identity theft - S: Social engineering - H: Human error

Mini Scenarios

Here are three short scenarios: - Basic: An employee receives an email from a colleague asking for sensitive information. What should the employee do? - What is happening: The employee is being targeted by a phishing attack. - What the learner should notice: The email is from an unknown sender and asks for sensitive information. - Applied: A company's network is infected with ransomware. What should the IT team do? - What is happening: The company's network is infected with ransomware. - What the learner should notice: The IT team should isolate the affected system to prevent further spread of the malware. - Tricky: A user clicks on a suspicious link and downloads malware onto their device. What happens next? - What is happening: The user has downloaded malware onto their device. - What the learner should notice: The malware may encrypt data or steal sensitive information.
