5.6 Security awareness
📘CompTIA Security+ (SY0-701)
User Guidance (Security Awareness)
User guidance is all about teaching users how to act securely in an IT environment. Users are often the first line of defense against threats, so educating them is crucial. This guidance usually covers policies, best practices, and awareness about threats and safe behavior.
Here are the key areas:
1. Policy
- What it is: Policies are formal rules that users must follow regarding security. Think of them as instructions for safe behavior in the IT environment.
- Examples in IT:
- Acceptable Use Policy (AUP): Rules on how to use company systems, email, internet, and devices.
- Data Protection Policy: How users should handle sensitive data (e.g., encrypting emails, not sharing passwords).
- Why it matters: Ensures everyone follows the same security rules. Violations can lead to security incidents or compliance issues.
Exam Tip: Know the difference between policies, standards, procedures, and guidelines:
- Policy: High-level rule (mandatory)
- Standard: Specific rule to comply with policy
- Procedure: Step-by-step instructions
- Guideline: Recommended but optional practices
2. Situational Awareness
- What it is: Users must understand their surroundings and recognize unusual behavior that could indicate a threat.
- Examples in IT:
- Noticing suspicious emails or unexpected login requests.
- Recognizing devices connected to the network that don’t belong.
- Detecting unusual system messages or errors.
- Why it matters: Helps detect threats early before they escalate into bigger problems.
3. Insider Threat
- What it is: Threats coming from within the organization, such as employees, contractors, or anyone with internal access.
- Types:
- Malicious insider: Someone intentionally stealing or damaging data.
- Negligent insider: Accidentally causes a breach (e.g., sharing a password or clicking a phishing link).
- User guidance:
- Only access data needed for your role (principle of least privilege).
- Report suspicious behavior from colleagues or unusual system activity.
4. Password Management
- What it is: Techniques to keep passwords secure and reduce the risk of unauthorized access.
- Best practices:
- Use strong, unique passwords for every account.
- Enable multi-factor authentication (MFA) wherever possible.
- Avoid sharing passwords.
- Use password managers to store and generate strong passwords.
- Common mistakes to avoid: Using “password123,” reusing passwords across multiple accounts, or writing them on sticky notes.
Exam Tip: Understand that password hygiene and MFA are critical in preventing account compromises.
5. Removable Media
- What it is: External devices like USB drives, external hard drives, or memory cards.
- Risks:
- Malware can spread through infected USB drives.
- Data leakage if sensitive files are copied.
- User guidance:
- Scan removable media for malware before use.
- Avoid using untrusted or unknown USB drives.
- Encrypt sensitive data stored on removable media.
- Follow organization rules for removable media use.
6. Social Engineering
- What it is: Attacks where hackers manipulate people into revealing sensitive information or performing unsafe actions.
- Common types in IT:
- Phishing: Emails asking for login credentials or sensitive data.
- Pretexting: Pretending to be IT support to get information.
- Tailgating: Following someone into a secure area.
- User guidance:
- Verify the identity of anyone requesting sensitive information.
- Avoid clicking suspicious links or downloading unknown attachments.
- Report all social engineering attempts immediately.
7. Operational Security (OPSEC)
- What it is: Procedures that protect sensitive information during daily operations.
- User guidance in IT:
- Avoid sharing confidential information over unsecured channels.
- Ensure devices are locked when unattended.
- Limit discussions of sensitive projects in public or unsecured areas (even in virtual meetings).
- Follow change management and access control procedures.
- Why it matters: Prevents accidental or intentional leaks of critical information.
8. Hybrid/Remote Work Security
- What it is: Security guidance for users working outside the traditional office environment.
- Risks in IT:
- Using unsecured Wi-Fi networks.
- Mixing personal and work devices.
- Shadow IT (installing unauthorized apps or software).
- User guidance:
- Use VPNs when accessing company resources remotely.
- Keep personal and work devices separate.
- Apply updates and patches promptly.
- Follow company security policies even when working from home.
Summary Table (Quick Exam Reference)

✅ Exam Tips for this Section:
- Understand each type of guidance and how it applies to protecting data and systems.
- Know common threats like social engineering and insider threats and the user behaviors that prevent them.
- Be familiar with security measures like MFA, encryption, VPNs, and OPSEC principles.
- Remember that user guidance is preventive, not just reactive.
