10 Cybersecurity Best Practices

for SMEs in Malaysia

  • 2025, February

Did you know that approximately 85% of Malaysian SMEs have been subjected to cyber-attacks with 75% of those being threatened by multiple attacks? Malaysian small and medium enterprise.s continue to grapple with rising cybersecurity concerns as data loss emerges as the most critical cloud threat.

Unlike large corporations, many small businesses lack the resources to implement strong security measures, making them vulnerable to cybercriminals. From phishing scams to ransomware attacks, hackers exploit weak security systems to steal corporate data, disrupt operations, and demand ransom payments. This is because 97% of businesses in Malaysia have insufficient investments in cybersecurity strategies. 

To stay protected, SMEs must prioritise cybersecurity services and implement the best practices that help safeguard financial information, customer data, and business continuity. So, here are 10 essential cybersecurity measures every Malaysian SME should adopt. Some of these won’t cost your business a dime! 

  • Chapter Guide
  • 1. Implement Strong Password Policies

We understand having a lot of passwords is a pain. While it is tempting to use simple passwords across multiple accounts, resist that temptation! Weak passwords are one of the biggest security risks. So, to strengthen security:

  • Require passwords to be at least 12 characters long, including a mix of uppercase and lowercase letters, numbers, and special characters.
  • Enforce multi-factor authentication (MFA) for an extra layer of protection, ensuring that even if a password is compromised, unauthorised users cannot gain access.
  • Use password managers to store and generate secure passwords, reducing the need for employees to remember multiple complex passwords.
  • 2. Keep Software and Systems Updated

Do you keep the doors to your business unlocked beyond operating hours? No! Then running outdated software is the cyber equivalent to that—it gives hackers an easy way in. Cybercriminals exploit vulnerabilities in old software to access company data. To stay protected:

  • Regularly update operating systems, applications, and antivirus software.
  • Enable automatic updates where possible to avoid missing critical security patches.
  • Replace outdated software and hardware that no longer receives security updates.
  • 3. Secure Your Wi-Fi Network

Do you invite any random person to your homes? Of course, not. So using an unsecured Wi-Fi network is like an open invitation for cyber criminals. Make sure your wireless networks are properly protected with: 

  • WPA3 encryption for stronger security.
  • Change default router usernames and passwords to unique, strong credentials.
  • Set up a separate guest Wi-Fi for visitors to prevent unauthorised access to internal networks.
  • 4. Educate Employees on Cybersecurity Awareness

Human makes mistakes. Human error is one of the leading causes of cyber incidents. Some of your employees may unknowingly click on malicious links or fall for phishing scams. Regular training can help:

  • Teach employees to identify phishing emails, suspicious links, and scam tactics.
  • Conduct cybersecurity awareness workshops to reinforce good security habits
  • Implement a company-wide cybersecurity policy with clear guidelines on handling sensitive data.
  • 5. Use Firewalls and Antivirus Software

Remember when we all had to wear face masks during the lockdown? A firewall is that but for your business. It acts as a digital barrier between your business network and potential cyber threats, while antivirus software detects and removes malware. SMEs should:

  • Install and configure firewalls to prevent unauthorised access.
  • Use reputable antivirus and anti-malware software to scan for threats.
  • Schedule regular security scans to detect and remove vulnerabilities before they can be exploited.
  • 6. Regularly Back Up Critical Data

Cyberattacks, hardware failures, or accidental deletions can result in data loss. To prevent this, SMEs must have a solid corporate data backup strategy:

  • Perform automated daily backups for critical data
  • Store backups in both cloud-based and offsite backup solutions for added security.
  • Regularly test backup recovery to ensure that data can be restored when needed.
  • 7. Implement Role-Based Access Control (RBAC)

Not all employees need access to all company data. Role-Based Access Control (RBAC) ensures that sensitive information is only accessible to authorized personnel.

  • Assign permissions based on job roles to limit access to critical data.
  • Restrict admin privileges to only a few trusted employees.
  • Regularly review and update access permissions to ensure security as employees change roles.
  • 8. Monitor and Detect Cyber Threats

Cyber threats are like a tumour- often undetected until it’s too late. Implementing proactive monitoring tools can help identify and prevent attacks before they cause damage:

  • Use intrusion detection systems (IDS) to spot suspicious activity.
  • Set up alerts for unauthorised logins, failed access attempts, or unusual file changes.
  • Consider partnering with a cybersecurity company in Malaysia for round-the-clock security monitoring.
  • 9. Develop a Cyber Incident Response Plan

No security system is foolproof. So, you’ll need a cyber incident response plan to handle potential breaches. Make sure your plan includes:

No security system is foolproof. So, you’ll need a cyber incident response plan to handle potential breaches. Make sure your plan includes:

  • 1. Detecting the breach – Identifying unauthorised access or cyberattacks.
  • 2. Containing the damage – Isolating affected systems to prevent further spread.
  • 3. Recovering data – Restoring lost or compromised information from backups.
  • 4. Reporting the incident – Notifying relevant authorities and affected parties.

Having a dedicated cybersecurity response team can ensure swift action during an attack.

  • 10. Ensure Compliance with Malaysia’s Cybersecurity Regulations

Our country has strict data protection laws that SMEs must follow to avoid legal issues and fines. Some of the key regulations include:

  • Personal Data Protection Act (PDPA) – Requires businesses to secure customer data and prevent unauthorised use.
  • CyberSecurity Malaysia Guidelines – Provides best practices and cybersecurity recommendations for businesses.
  • Conducting regular security audits helps SMEs stay compliant and identify potential vulnerabilities.

These regulations are here for a reason and adhering to this will ensure your business are properly protected from cyber criminals looking to take your hard-earned money.

Additionally, businesses should consider data centre recovery solutions like MyCloud to ensure they can quickly resume operations after a cyber incident or system failure.

  • How MyCloud Can Help Secure Your Business
