8 cybersecurity myths in 2026: The truth & practical solutions

In the era of the Generative AI explosion, the cybersecurity landscape globally and within Vietnam has undergone a pivotal transformation.

According to reports from the Authority of Information Security (AIS) as of early 2026, Ransomware attacks and Deepfake fraud have increased by 45% compared to the previous year. Despite this, many enterprises continue to operate based on obsolete security mindsets.

Below is a detailed analysis of the 8 most common cybersecurity myths and the reality behind them.

1. Myth: "Small businesses are not targets for hackers"

• The Truth: Small and Medium Enterprises (SMEs) are often the preferred "gateways" for hackers due to weaker defensive systems.

• 2026 Reality: More than 60% of current cyberattacks target small businesses as a stepping stone to infiltrate the supply chains of larger corporations.

  • Solution: Implement periodic cybersecurity assessment services to identify vulnerabilities before they are exploited.

2. Myth: "Antivirus software alone provides enough safety"

• The Truth: Traditional antivirus software only blocks known malware signatures.

• Technical Analysis: Modern hackers utilize AI-driven Malware capable of self-modifying its source code to bypass standard firewalls and conventional antivirus layers.

  • Solution: Equip your organization with EDR/XDR systems and 24/7 monitoring from professional SOC centers.

3. Myth: "A strong password is an impenetrable barrier"

• The Truth: With the support of quantum computing and AI, even the most complex passwords can be cracked via Brute-force methods or Social Engineering.

• Data Insight: 81% of data breaches are related to compromised passwords.

  • Solution: Apply Multi-Factor Authentication (MFA) and Zero Trust architecture (Never Trust, Always Verify).

4. Myth: "Threats only come from outside the system"

• The Truth: Insider Threats—whether accidental or intentional—account for 34% of all data leaks.

• Vietnam Context: Employees clicking on malicious links via social media remains a leading cause of information insecurity within local organizations.

  • Solution: Conduct cybersecurity awareness training and utilize Managed Security Services to enforce strict access controls.

5. Myth: "Cybersecurity is strictly the responsibility of the IT department"

• The Truth: Information security is every individual's responsibility and a vital survival strategy for leadership.

• E-E-A-T Standard: An organization with solid infrastructure but staff who lack response skills remains a fragile system.

  • Solution: Build a corporate security culture from management down to every employee.

6. Myth: "Data on the Cloud is secure by default"

• The Truth: Cloud providers (AWS, Azure, Google Cloud) only secure the infrastructure; securing the data within it is the user's responsibility (Shared Responsibility Model).

• Note: Cloud misconfiguration was the primary cause of major data leaks in 2025.

  • Solution: Utilize specialized Cloud security control tools.

7. Myth: "Mac and Linux systems cannot be infected by malware"

• The Truth: While Windows is more common, malware targeting macOS and Linux servers has grown significantly over the past two years due to the high value of the data they hold.

• Evidence: APT (Advanced Persistent Threat) campaigns frequently use backdoors on Linux platforms to maintain long-term persistence within a network.

8. Myth: "Investing in cybersecurity is an expensive burden"

• The Truth: The cost of remediation after an attack (including ransom, legal fines under Decree 13/2023/NĐ-CP, and brand damage) is many times higher than the cost of prevention.

• ROI (Return on Investment): Early security investment minimizes business disruption risks and ensures enterprise continuity.
