Network-attached storage (NAS) has become more popular as people tend to store larger files such as videos, photos, and documents in the cloud. However, it is crucial to understand that security threats exist even in this seemingly secure and closed system. Recently, numerous cases have shown that NAS devices can be easily hacked, resulting in the leak of sensitive and confidential information. In this blog, we will discuss what NAS security entails and what you can do to protect your data.
What is NAS Security?
NAS security refers to the measures or protocols used to protect data stored on a NAS system from unauthorized access, theft, or compromise. NAS security involves ensuring that the network, server, and the NAS storage device itself are secure from cyber threats. In NAS, data is not generally stored on the desktop computer or laptop, but on the NAS device, visualized over the network.
What are the Common Security Threats to Nas Devices?
Cyberattacks and data breaches are the most common threats to NAS devices. The threats can be in the form of viruses, ransomware, phishing attacks, network sniffing, and distributed denial-of-service attacks (DDoS). These attacks can come from internal or external sources, including employees, partners, or hackers. With the rise in virtual teams working remotely, the attack surface has increased, with more devices accessing the NAS system from different locations.
Nas Security Best Practices
The following are some NAS security best practices that you can implement to protect your data.
- Install Only Authorized Applications
Only install authorized applications on your NAS device that you need to access. Installing unnecessary third-party applications adds to the risk of vulnerability.
- Configure Strong Passwords
Always use strong passwords and change them regularly, especially for the administrative account. Avoid using simple passwords that are easy to guess.
- Enable Two-factor Authentication
Two-factor authentication (2FA) adds an extra layer of security to your NAS device. Avoid using SMS as the message could be intercepted.
- Use Encryption
Encrypt your data to protect it from unauthorized access, whether stored internally on your NAS device or while transmitting it over the network.
- Keep Your Software up to date
Keep your NAS firmware and software up to date to ensure that known vulnerabilities are addressed.
What to Do If Your Nas Device Is Hacked?
In case your NAS device is hacked, the first step is to disconnect it from the internet. You should also notify your IT security team, who will help you contain the threat, identify the compromised data, and work to recover any lost data. It is also essential to change all your SSH, SFTP, and NAS device admin account credentials. In more severe cases, it may be necessary to reset the NAS appliance device to its default settings and reinstall the operating system.
Conclusion
In conclusion, NAS devices, while convenient and efficient for storing your data, can pose a significant security risk. By implementing NAS security best practices, you can reduce the risk of cyber attacks and protect your sensitive data. If your NAS device is hacked, report the incident immediately to your IT security team or an expert in the field of cybercrime. Stay informed with the latest security threat trends and stay vigilant. Always remember that prevention is better than cure.
