5 Ways to Keep Your Apple Mac Computers Secure

5 Ways to Keep Your Apple Mac Computers Secure

For years, Apple has marketed its products as secure alternatives to Windows PCs, convincing many business owners that their Mac systems are impervious to malware. However, the recent discovery of LightSpy spyware targeting macOS should serve as a wake-up call: Macs are not invulnerable.

LightSpy, previously known for targeting Android devices, has now expanded its reach to macOS. This shift highlights a growing trend among cybercriminals: attacking whatever platform offers the highest returns. Apple’s increasing market share makes its products a lucrative target. As a result, business owners need to be vigilant about securing their Mac systems. Here are five essential steps to keep your Macs secure:

1. Regular Updates

Ensuring that all systems are running the latest version of macOS is crucial. Apple frequently releases updates that patch security vulnerabilities. These updates are critical for protecting against newly discovered threats like LightSpy. Set up automatic updates to streamline this process and ensure no system is left exposed.

Keeping software up to date doesn’t stop with the operating system. Ensure all applications and plugins are regularly updated. Outdated software can have vulnerabilities that are easily exploited by cybercriminals. This includes not only major software like browsers but also lesser-known applications that might not seem like obvious targets. Implementing a patch management system can help automate and monitor these updates, making the process more efficient and reducing the risk of human error.

2. Use Security Software

Investing in reputable security software designed for macOS is essential. While historically less common, there are now several robust options available. These programs can detect and neutralize threats, offering an additional layer of protection against malware and spyware.

Choose a comprehensive security suite that includes antivirus, anti-malware, and firewall protection. Look for features like real-time scanning, automatic updates, and behaviour-based detection, which can identify threats based on their actions rather than relying solely on known signatures. Regularly run full system scans and ensure that all security software is properly configured to provide maximum protection.

Don’t forget to secure your network as well. Use a robust firewall and consider setting up a virtual private network (VPN) for remote connections. This adds an additional layer of security, ensuring that data transmitted between devices remains encrypted and secure.

3. Employee Training

Educating employees about the risks of phishing and suspicious downloads is vital. Cybersecurity is as much about human vigilance as it is about technological defences. Regular training sessions can help employees recognize and avoid potential threats, reducing the risk of accidental malware installation.

Start with the basics: teach employees how to identify phishing emails, suspicious links, and malicious attachments. Use real-world examples and simulations to make the training more engaging and effective. Emphasize the importance of verifying the sender’s identity before clicking on any links or downloading attachments.

Encourage a culture of security awareness. Make it easy for employees to report suspicious emails or activities without fear of reprisal. Regularly update training materials to reflect the latest threats and best practices. Consider implementing a security awareness program that includes ongoing education, regular testing, and clear policies for handling sensitive information.

4. Monitor Network Traffic

Implementing network monitoring tools to detect unusual activity that could indicate a breach is crucial. By keeping an eye on network traffic, you can identify and respond to threats more quickly. These tools can alert you to suspicious behaviour, allowing you to take immediate action to protect your data.

Choose network monitoring solutions that provide real-time visibility and detailed analytics. Look for features such as anomaly detection, which can identify deviations from normal network activity, and automated response capabilities, which can help mitigate threats quickly. Regularly review logs and reports to stay informed about the health and security of your network.

Consider integrating network monitoring with other security tools, such as intrusion detection systems (IDS) and security information and event management (SIEM) solutions. This can provide a more comprehensive view of your security posture and help you detect and respond to threats more effectively.

5. Backup Data

Regularly backing up important data to a secure, offsite location is essential. In the event of a malware attack, having backups can mitigate the damage and ensure business continuity. Automated backup solutions can make this process easier and more reliable, ensuring that your data is always protected.

Implement the 3-2-1 backup strategy: keep three copies of your data, store two copies on different media (such as an external hard drive and a network-attached storage device), and keep one copy offsite (such as in the cloud). This approach ensures that your data is protected against a variety of threats, including hardware failure, natural disasters, and cyberattacks.

Regularly test your backups to ensure that they can be restored quickly and accurately. Implement backup monitoring to receive alerts if backups fail or if there are any issues that need to be addressed. Consider using encryption to protect your backup data, both in transit and at rest, to prevent unauthorized access.


The LightSpy incident is a reminder that security is a moving target. As macOS grows in popularity, so does its attractiveness to cybercriminals. Business owners must adapt to this reality by treating their Mac systems with the same level of scrutiny and protection as any other platform.
