6.3 Summarize behavioral security concepts.

📘CompTIA ITF+ (FC0-U61)


Confidential information is any data that should be protected from unauthorized access. In IT, this usually includes passwords, personal information, customer information, and company confidential information. Let’s go through each category:


1. Passwords

Passwords are the most common form of access control. They are used to verify a user’s identity before allowing access to systems, accounts, or data.

Best practices for handling passwords:

  • Keep passwords secret: Never share your passwords with anyone, even colleagues.
  • Use strong passwords: Combine uppercase, lowercase, numbers, and special characters. Avoid simple or common passwords like 123456 or password.
  • Use unique passwords: Don’t reuse the same password for multiple systems.
  • Change passwords regularly: Some systems require periodic password changes to stay secure.
  • Use a password manager: Software like LastPass or Bitwarden helps store and encrypt passwords securely.

Why it matters: If passwords are stolen, attackers can access systems and sensitive data, which may lead to identity theft or data leaks.


2. Personal Information

Personal information includes data that identifies an individual, such as:

  • Name
  • Address
  • Phone number
  • Social security number
  • Email addresses

Handling personal information in IT:

  • Limit access: Only give access to people who need it for work purposes.
  • Encrypt sensitive data: Use encryption when storing or sending personal information.
  • Secure deletion: Delete personal information securely when no longer needed. This prevents recovery from old files or backups.

Why it matters: Exposure of personal information can lead to phishing attacks, identity theft, or privacy violations.


3. Customer Information

Customer information includes any data about clients, such as:

  • Purchase history
  • Account numbers
  • Contact information
  • Support tickets

Handling customer information in IT:

  • Use access controls: Employees should only see the customer data necessary for their job.
  • Avoid sharing externally: Don’t send customer data to personal email accounts or unapproved applications.
  • Monitor access logs: Systems should track who accessed customer information and when.

Why it matters: Mishandling customer information can damage trust, harm the company’s reputation, and violate privacy laws.


4. Company Confidential Information

This includes internal company data that is sensitive, such as:

  • Financial records
  • Product designs or plans
  • Internal emails and memos
  • Security procedures

Handling company confidential information in IT:

  • Use encryption and secure storage: Protect files on servers and cloud systems.
  • Limit sharing: Only share with authorized personnel inside the company.
  • Label sensitive documents: Mark documents as confidential to remind users to handle carefully.
  • Follow company policies: Always follow organizational procedures for handling, storing, and disposing of confidential data.

Why it matters: Leaking company secrets can lead to financial loss, competitive disadvantage, or legal problems.
