Security Issues

  • When moving electronic data from one place to another, there are different types of security concerns to consider:
    • Data interception can occur when an unauthorised user intercepts data being transferred.
      • Two common methods are:
        • Packet sniffing
        • Man in the middle attack

  • Encryption can be broken if it is not strong

  • Using HTTP instead of HTTPS protocols when dealing with sensitive information

  • Depending on whether the data being sent is sensitive will depend on the level of security needed to ensure it stays safe
  • All types of information will need to be transferred from one place to another at some point but typical examples may include:
    • User credentials when logging into online banking
    • Medical records being passed from a hospital to a GP
    • Student details from one school to another
    • Criminal records and details
  • When dealing with personal or sensitive data it is essential that not only is it protected from hackers but also that it is protected from accidental disclosures such as:
    • Sending an email with sensitive information to the wrong person
    • Losing a device that has sensitive data stored
    • Shared access misconfigurations allow unauthorised users access to sensitive data
