Explain the difference between data validation and data verification, providing a unique example for each that is not found in the text.
Data validation checks if the data meets specified criteria (e.g., checking if a phone number is in the correct format). Data verification ensures the accuracy of data by comparing it to its original source (e.g., confirming a customer's address with postal records).
How might a company's internal vulnerabilities make it more susceptible to external threats? Provide an example.
How might a company's internal vulnerabilities make it more susceptible to external threats? Provide an example.
Weak internal access controls or unpatched systems can provide an easier entry point for external attackers. For example, if employees use weak passwords, hackers could exploit compromised accounts to infiltrate the network.
Differentiate between accidental and deliberate threats. Give an example of a threat that could be either accidental or deliberate, depending on the context.
Differentiate between accidental and deliberate threats. Give an example of a threat that could be either accidental or deliberate, depending on the context.
Accidental threats are unintentional mistakes causing harm (e.g., spilling coffee on a server), while deliberate threats are intentional malicious acts (e.g., intentionally planting a virus). Data deletion could be accidental (e.g., deleting the wrong file) or deliberate (e.g., a disgruntled employee deleting company data).
A company uses keycard access for its building. Is this physical or logical access control? Explain how this mechanism contributes to overall security.

Study Notes
- Data validation confirms data meets particular requirements, while verification confirms data accuracy by comparing it to the original source
- Validation example: Confirming age is within the range of 1–100
- Verification example: Double entry of passwords or email addresses
- Validation answers "Is data reasonable and allowable?"
- Verification answers "Is data correct and matches its source?"
Identifying Threats
- Internal threats originate from within the organization
- External threats originate outside the organization
- Internal threat example: A disgruntled employee deleting files
- External threat example: Hackers trying to breach firewall security
- Accidental threats are unintentional mistakes causing damage or security risks
- Deliberate threats are purposeful acts intended to harm or disrupt
- Accidental threat example: Employee accidentally deleting data
- Deliberate threat example: Intentional virus release or hacking attempts
Security Mechanisms
- Physical access control manages physical entry or interaction with hardware or infrastructure
- Logical access control manages digital access to information systems or networks
- Physical control examples: Locks, cameras, badges, biometric scanners, security guards
- Logical control examples: Passwords, encryption, firewalls, two-factor authentication (2FA)
Security Policies and Practices for Data Usage
- Security policies are clearly defined rules and protocols regarding data handling, storage, access, sharing, and disposal
- Examples of good practices:
- Acceptable Use Policy (AUP) provides guidelines on permitted use of resources
- Password Policies set requirements for complexity and regular updates
- Data Encryption is used for sensitive or personal data
- Backup Policies include regular backups and restoration plans
- User Training includes regular security awareness and compliance training
