Are your valuable files and data on your Synology NAS at risk of being held for ransom by cybercriminals? Ransomware attacks have become increasingly common in recent years, leaving victims with no choice but to pay a hefty sum to regain access to their own files. However, there are steps you can take to secure your Synology NAS from these types of attacks. In this blog post, we’ll share 5 actionable steps that you can implement today to keep your data safe and secure. Don’t wait until it’s too late – read on to learn how you can protect yourself from ransomware attacks on your Synology NAS.

Step #1: Keep Your Synology NAS Updated

One of the most crucial steps to keep your Synology NAS safe from ransomware attacks is making sure that it is always up-to-date. Regular software updates are commonly released by Synology, which include security patches and bug fixes. Failing to update your system can leave vulnerabilities for attackers to exploit.

Thankfully, updating your Synology NAS is a relatively simple process. You can do this manually or set up an automatic update schedule in the Control Panel under “Update & Restore.” It’s important to note that you should check for updates regularly as they aren’t pushed out automatically.

It’s also worth noting that while software updates may seem like a hassle, they’re much easier than dealing with a ransomware attack. In some cases, these attacks can be catastrophic, resulting in data loss or even complete system failure.

In addition to keeping your operating system updated, it’s essential always to keep any third-party applications installed on your SynologyNAS current as well. This includes antivirus software and other applications used regularly on your device.

By staying vigilant about updating all aspects of your Synology NAS regularly, you greatly reduce the risk of becoming vulnerable to ransomware attacks and other security breaches.

Step #2: Use a Strong Password

Using a strong password is crucial for securing your Synology NAS from ransomware attacks. A weak password can easily be hacked by cybercriminals, leading to unauthorized access to your device and data.

When creating a password, avoid using common phrases or words that are easy to guess. Instead, use a combination of uppercase and lowercase letters, numbers, and special characters. The longer the password, the better.

It’s also important to avoid using the same password across all your accounts. If one account gets compromised, it could lead to all your other accounts being hacked as well.

Consider using a reputable password manager tool that generates strong passwords for you and stores them securely. This will not only help you create stronger passwords but also make it easier for you to manage them across multiple devices.

Remembering numerous complex passwords may seem overwhelming at first. But investing in robust passwords is an investment in security that will pay off in the long run when it comes to protecting your data against ransomware attacks on your Synology NAS.

Step #3: Use Two-Factor Authentication

Two-factor authentication (2FA) adds an extra layer of security to your Synology NAS. With 2FA enabled, you need to provide a second form of identification in addition to your password when logging in. This can be done via a code sent to your mobile device or through biometric verification.

Enabling 2FA is easy on the Synology DSM interface. First, make sure that you have updated the firmware of the device as mentioned in Step #1. Then navigate to Control Panel > User > Advanced tab and select “Enable two-step verification.” Once enabled, users will be prompted to set up their preferred method for receiving codes.

It’s essential not only for personal accounts but also business environments where multiple users have access privileges. Enforcing 2fa as mandatory for user logins ensures that everyone is accountable and secure from cyber threats.

Using two-factor authentication is one way you can add an additional layer of protection against unauthorized login attempts and ransomware attacks on your Synology NAS devices.

Step #4: Configure Firewall Settings

Firewalls are an essential part of securing your Synology NAS from ransomware attacks. A firewall acts as a barrier between your network and the internet, filtering out potentially harmful traffic and only allowing trusted connections to pass through.

To configure your Synology NAS’ firewall settings, first navigate to the Control Panel and select “Security.” From there, open the “Firewall” tab and enable it if it’s not already turned on.

Next, you’ll want to configure specific rules for inbound and outbound traffic. For example, you can block incoming traffic from countries known for cybercrime or limit access to certain ports that aren’t necessary for regular use.

It’s also important to regularly review your firewall logs to identify any suspicious activity or attempts at unauthorized access. By keeping an eye on these logs, you can take action quickly in case of a potential breach.

Configuring your Synology NAS’ firewall settings is crucial in preventing ransomware attacks and ensuring the safety of your data.

Step #5: Install Antivirus Software

Installing an antivirus software on your Synology NAS is a crucial step in securing it from ransomware attacks. The antivirus software will scan all the files and folders stored on your NAS and detect any malicious code or infected files that could potentially harm your data.

There are many different types of antivirus software available for Synology NAS, but it’s important to choose one that is specifically designed for this purpose. Some popular options include McAfee, Avast, and ClamAV.

Once you have installed the antivirus software on your Synology NAS, make sure to keep it updated regularly. This will ensure that you always have the latest virus definitions and protection against new threats.

It’s also important to configure the settings of your antivirus software correctly. For example, you can schedule regular scans of your system or set up real-time scanning to detect any viruses as soon as they enter your network.

In addition to installing an antivirus program on your Synology NAS, it’s also a good idea to install additional security measures such as intrusion detection systems (IDS) or network analysis tools (NAT). These tools can help monitor traffic entering and leaving your network and alert you if any suspicious activity is detected.

Installing an antivirus program is just one part of securing your Synology NAS from ransomware attacks. By following all five steps outlined in this article, you’ll greatly reduce the risk of becoming a victim of cybercrime.


Securing your Synology NAS from ransomware attacks requires a few simple yet crucial steps. Keeping your software updated, using strong passwords and two-factor authentication, configuring firewall settings, and installing antivirus software are all essential measures to prevent cyber threats.

Taking these preventive measures might take some time and effort but it is worth it in the long run as they help safeguard against data loss and unauthorized access to sensitive information.

Remember, in today’s digital age where cyber threats are increasingly prevalent, ensuring the security of your Synology NAS should be a top priority. By following these five steps outlined above, you can protect yourself from potential ransomware attacks and keep your data safe.
