Are you worried about the safety of your Synology NAS? With ransomware attacks becoming more common, it’s important to take preventative measures to safeguard your valuable data. Fortunately, protecting your Synology NAS is easier than you might think! In this blog post, we’ll guide you through five simple steps that can help keep your device secure and protect against potential threats. From configuring DSM settings to enabling two-factor authentication, we’ve got you covered. So sit back, relax and learn how to better protect yourself from ransomware attacks on your Synology NAS!

Install Synology NAS and DSM

The first step to safeguard your Synology NAS against ransomware attacks is to install the device and its operating system, known as DSM (DiskStation Manager). You can do this either by purchasing a pre-built Synology NAS or building your own.

Once you have your device up and running, it’s time to set up DSM. This involves creating an account with Synology and accessing their web-based interface. From there, you’ll be able to configure various settings related to security, user access, network connectivity and more.

One important thing to keep in mind during installation is firmware updates. These updates are crucial for patching vulnerabilities in the system that may be exploited by cybercriminals. Be sure to check for updates regularly and apply them as soon as possible.

Installing Synology NAS and DSM is a straightforward process that lays the foundation for protecting your data from ransomware threats. By following best practices such as regular firmware updates and proper configuration of DSM settings, you’ll be well on your way towards maintaining a secure environment for storing your valuable files.

Configure DSM Settings

Configuring DSM (Disk Station Manager) settings is an essential step in safeguarding your Synology NAS against ransomware attacks. It allows you to customize the security features and ensure the protection of your data from unauthorized access.

One crucial setting is enabling automatic updates for the DSM operating system and installed packages. Regular updates provide bug fixes, new features, and most importantly, security patches that address vulnerabilities exploited by ransomware attacks.

Another important configuration is setting up a firewall to restrict network traffic based on specific rules. This way, you can block any suspicious incoming or outgoing connections that might be malicious.

DSM also offers built-in security measures such as disabling services that are not in use, restricting external access only to authorized IPs or networks, and configuring log management for detecting suspicious activities.

Moreover, you can set up notifications via email or SMS whenever there’s an attempted login with invalid credentials or a possible ransomware attack detected by the antivirus software.

By following these steps and customizing the DSM settings according to your needs will significantly improve the overall security posture of your Synology NAS.

Set up users and permissions

Setting up users and permissions is crucial in safeguarding your Synology NAS against ransomware attacks. By doing this, you can control who has access to the files stored in your network-attached storage device.

Firstly, it’s important to create individual user accounts for each person who needs access to the files on your NAS. This will help you track any suspicious activity and limit the damage that could be caused by an attack.

Secondly, make sure that you assign specific permissions to each user. You may want some people to have read-only access or limit their file management options while others require full admin privileges. This step ensures that only authorized personnel can modify or delete data on your storage device.

Thirdly, consider using ACL (Access Control List) settings which provide granular control over shared folders and keeps a log of all file operations performed by users.

By setting up users and permissions properly, you’re taking another necessary step towards ensuring your Synology NAS stays protected from potential ransomware threats.

Install security packages

Installing security packages is an essential step to safeguard your Synology NAS against ransomware attacks. By adding these packages, you can add an extra layer of protection that will help keep your data safe from any potential threats.

Synology offers a variety of security packages that you can install directly from the Package Center. For example, Antivirus by McAfee provides real-time scanning and detection for malware and viruses on your NAS system. Additionally, the Security Advisor package can help identify any vulnerabilities in your network setup or user permissions.

Another useful package is the AppArmor package, which adds another level of access control by restricting what files and directories each application can access. This means that even if one app gets compromised, it won’t be able to harm other parts of your system.

Installing security packages is a critical step in protecting your Synology NAS from ransomware attacks. By taking advantage of these tools offered by Synology, you’ll be better equipped to defend against any potential threats that may arise in the future.

Enable two-factor authentication

One of the most effective ways to safeguard your Synology NAS against ransomware attacks is by enabling two-factor authentication. This security feature adds an extra layer of protection beyond a simple password, making it more difficult for attackers to gain access to your device.

Enabling two-factor authentication on your Synology NAS is relatively easy. First, make sure that you have set up users and permissions correctly as mentioned in the previous section. Then, navigate to the Control Panel in DSM and select “User” from the dropdown menu.

Select “Edit” next to the user account that you want to enable two-factor authentication for, then click on “Enable Two-Factor Authentication”. You can choose between various methods such as OTP (one-time password), TOTP (time-based one-time password), or FIDO U2F (universal second factor) depending on your preference.

Once you have enabled two-factor authentication, every time someone tries to log in with that user’s credentials they will be required to enter an additional code generated by a secondary device such as a smartphone app or hardware key fob. This makes it much harder for hackers who might have obtained stolen login credentials through phishing schemes or other means.

In short, enabling two-factor authentication is an essential step towards securing your Synology NAS against ransomware attacks and should not be overlooked.


By following these 5 simple steps, you can significantly improve the security of your Synology NAS against ransomware attacks. Installing DSM and configuring its settings will ensure that your system is up-to-date with the latest security patches. Setting up users and permissions will help to prevent unauthorized access to sensitive data. Furthermore, installing security packages such as Antivirus Essential and enabling two-factor authentication can provide an additional layer of protection.

It is important to remember that cybersecurity threats are constantly evolving, so it’s essential to keep your Synology NAS updated regularly and stay informed about new vulnerabilities or risks.

By taking a proactive approach towards securing your Synology NAS, you can minimize the risk of falling victim to a ransomware attack and protect yourself from potential financial loss or data breaches. With these simple tips in mind, you’ll be able to enjoy all the benefits of having a secure storage solution without worrying about becoming another statistic in the ongoing battle against cybercrime.
