Unit 8 - Worksheet 1 Notes

Definition of Computing Innovation

  • Computing Innovation: An innovation that incorporates software code into its operation.

Payment for Free Apps

  • "Paying" for Free Apps: Users often pay for free applications through acceptance of terms in the Privacy Policy. Companies embed conditions within these policies that users may not fully understand or may not want to agree with, yet users agree to them, resulting in a quick transition to the use of the app.

Personally Identifiable Information (PII)

  • Definition of PII: Personally Identifiable Information refers to a collection of data points about an individual that can be used to identify them specifically.

  • Identity Theft Using PII: PII can be exploited to steal identities by compiling enough data to create a detailed profile of a person, which can then be used for fraudulent purposes.

Unintended Consequences of Computing Innovations

  • Impact of Data Permanence: All data published on the Internet is essentially permanent and can resurface unexpectedly, leading to unintended consequences. This highlights the need for careful consideration of information shared online.

Importance of Multiple Perspectives in Innovation

  • Bringing Together Perspectives: Engaging multiple perspectives in discussions about new computing innovations is crucial to identify potential risks and enhance the overall safety and effectiveness of the innovation.

Keylogging

  • Definition of Keylogging: Keylogging refers to the use of software designed to log every keystroke made by a user on their computer. This practice is typically executed to gain unauthorized access to passwords and other confidential information.

Phishing

  • Definition of Phishing: Phishing involves deceptive attempts to trick users into divulging personal information. This information can then be utilized to gain unauthorized access to online resources, such as bank accounts and personal email accounts.

Malware

  • Definition of Malware: Malware comprises various types of software that intend to inflict damage on a computing system or gain unauthorized control over its operations. This includes a wide array of threats resulting from such malicious software.

Rogue Access Point

  • Definition of Rogue Access Point: A rogue access point is a wireless access point that enables unauthorized access to secure networks. This can pose significant security risks to sensitive information.

Encryption and Decryption

  • Encryption: The process of encoding a message to ensure its confidentiality. The resulting encrypted message is unreadable without the corresponding decryption key.

  • Decryption: The opposite of encryption; it involves taking an encoded message and converting it back into its original plain text format.

Symmetric vs. Asymmetric Encryption

  • Keys in Symmetric Encryption: Requires 1 key for both encryption and decryption.

  • Keys in Asymmetric Encryption: Utilizes 2 keys—a public key for encryption and a private key for decryption. This method allows the sender to encrypt a message without needing the recipient's private key.

  • Current Use on the Internet: The predominant encryption method employed today is Asymmetric Encryption.

Password Security

  • Characteristics of a Good Password: A strong password is one that is easy for the user to remember while being difficult for others to guess based on information they might know about the user.

Multifactor Authentication

  • Definition of Multifactor Authentication: A security mechanism requiring users to present proof from at least two of the following categories to authenticate:
      1. Knowledge: Something the user knows (e.g., a password).
      2. Possession: Something the user has (e.g., a security token).
      3. Inherence: Something intrinsic to the user (e.g., biometric verification).

Data Protection Strategies

  • Ways to Protect Your Data: 4 effective strategies include:
      1. Utilize strong passwords.
      2. Enable multifactor authentication.
      3. Keep software up to date.
      4. Exercise caution regarding which links are clicked and which software is installed.
