Many businesses approach network security like making a fortress made out of pillows, chairs, and blankets. But the internet is a much scarier place than one’s living room. And many businesses neglect their security measures, leaving their data exposed to cyber threats. 

This negligence often leads to costly breaches and operational disruptions.

In hopes to protect your business and keep you on your toes, we’re debunking common myths about network security to help safeguard your business effectively.

What is Network Security 

Network security is the practice of protecting a computer network against unauthorised access, misuse, or theft. It combines multiple layers of defenses and creates a secure infrastructure for devices, applications, and users. It’s essential for maintaining the security of sensitive information and limits uninterrupted business operations.

Why Network Security is Important 

Unless you want to have a system filled with bugs and potential threats, network security is something you don’t want to neglect. Below are some key reasons why: 

• Protects sensitive information from unauthorised access

• Prevents costly cyberattacks

• Safeguards customer trust

• Certifies adherence to regulatory standards

• Avoids operational disruptions

• Mitigates financial losses

Network Security Myths Debunked 

Now, let’s go over 17 common myths about network security and reveal the truth behind each one. Understanding these misconceptions will help you better shield your business and make wiser decisions about your network security strategy.

1. Small businesses aren't targets for cyberattacks: Small businesses are actually frequent targets because they often have weaker security measures, making them easier to exploit. In fact, 61% of small and medium-sized businesses (SMBs) were successfully attacked by cybercriminals in 2023.
   

2. Antivirus software alone is enough protection: Antivirus software is just one layer of defense and cannot protect against all types of cyber threats, such as phishing or ransomware attacks. Modern threats often require advanced detection systems and comprehensive security strategies.
   

3. Strong passwords are sufficient: As of June 20204, 4 million people around the globe still use "password" as the password for their accounts. Hopefully you're not one of them. And while important, strong passwords alone do not provide complete security. Cybercriminals can use techniques like phishing and keylogging to bypass even the strongest passwords. Multi-factor authentication (MFA) adds an essential extra layer of security.
   

4. Cyber Security is only an IT department issue: Cyber security is a company-wide responsibility that requires awareness and participation from all employees. For instance, regular training on recognising phishing emails can prevent breaches initiated by human error.
   

5. Firewalls alone provide complete security: Firewalls are just one component of a multi-layered security strategy. They need to be complemented with intrusion detection systems, regular software updates, and user education to be effective.
   

6. Security breaches are immediately noticeable: Many breaches can go undetected for long periods. For example, the Marriott data breach in 2014 went unnoticed for four years, exposing the personal information of 500 million guests.
   

7. Free security software offers the same protection as paid solutions: Free software often lacks the comprehensive features and support of paid solutions, such as advanced threat detection, regular updates, and customer support.
   

8. Cloud services are inherently insecure: Many cloud services offer robust security features, but they must be properly configured and managed. Misconfigurations, such as leaving cloud storage publicly accessible, have led to numerous data breaches.
   

9. Cyber Security is a one-time setup task: Effective cyber security requires continuous monitoring and updating. Cyber threats are constantly evolving, requiring ongoing adjustments to security strategies and tools.
   

10. Physical security measures are unnecessary: Physical access to network hardware can compromise security. For example, an intruder gaining physical access to a server room could install malicious hardware or software.
    

11. Mobile devices don't need the same security as desktops: Mobile devices are equally susceptible to cyber threats. They can be compromised through malware, phishing, and unsecured Wi-Fi networks, necessitating robust security measures.
    

12. Using a VPN makes you completely anonymous online: VPNs enhance privacy but do not guarantee complete anonymity. For example, if a user logs into their personal accounts while using a VPN, their identity can still be tracked.
    

13. Hackers only target financial data: Hackers target various types of sensitive information, not just financial data. Personal data, intellectual property, and medical records are also highly valuable and frequently targeted.
    

14. Security measures slow down business operations: Modern security solutions can be both efficient and effective. For instance, automated security systems and streamlined protocols can protect without significantly impacting productivity.
    

15. Social engineering attacks are easy to spot: Social engineering attacks can be highly sophisticated and difficult to detect. Cybercriminals often use detailed personal information to create convincing scams, such as spear-phishing emails.
    

16. Backup data doesn't need to be secured: Backup data is a prime target for cybercriminals and must be secured. Encrypting backups and storing them in secure locations can prevent unauthorised access and data breaches. Take a look at our Comprehensive Cloud Back Up & Recovery solutions.
    

17. Cyber insurance is unnecessary if you have strong security: Cyber insurance provides an additional layer of protection against potential financial losses from cyber incidents. It can help cover the costs of recovery, legal fees, and notification processes following a breach.

How to Implement Effective Network Security Measures

Implementing effective network security measures can seem like untangling knotted wire, but with the right approach and support, it can be manageable—even straightforward!

Here are seven practical steps to help you secure your business's data and operations.

1. Conduct a Comprehensive Security Audit

Start by assessing your current security posture and identifying areas for improvement. This baseline audit will serve as your roadmap, highlighting vulnerabilities and guiding your security strategy moving forward.

2. Implement Strong Access Controls

Certify that only authorized personnel have access to sensitive information. Implement multi-factor authentication and role-based access controls to restrict access and protect critical data.

3. Regularly Update and Patch Systems

Keep all software and systems up-to-date to protect against known vulnerabilities. Regular updates and patches are essential to close security gaps and defend against new threats.

4. Utilise Advanced Firewalls and Intrusion Detection Systems

Deploy firewalls to block unauthorised access and intrusion detection systems to monitor and respond to potential threats in real-time. These tools provide a robust defense against cyber attacks.

5. Educate and Train Your Employees

Security is a team effort. Regularly educate your employees about the latest cyber threats and best practices for maintaining security, such as recognising phishing attempts and following secure protocols.

6. Secure Mobile Devices and Remote Work Environments

Mobile devices and remote work setups should be protected with the same level of security as your main office. Use VPNs, encryption, and secure access protocols to safeguard data and communications.

7. Backup Data Regularly

Regularly backup your data to prevent loss in case of a cyberattack. Ensure that backups are encrypted and stored securely to protect against unauthorised access and data breaches. Take a look at our Comprehensive Cloud Back Up & Recovery solutions.
