Make Users Login To Synology Before Downloading External Internet
Recently, some Synology owners discovered that all the files on their NAS system were encrypted. Unfortunately, some ransomware had infected the NAS and demanded payment to restore the data. Here's what you can practice to secure your NAS.
How to Avert the Ransomware Attack
Synology is warning NAS owners of several ransomware attacks that hit some users recently. The attackers utilise creature-forcefulness methods to guess the default password—essentially, they endeavour every password possible until they get a match. One time they detect the correct password and gain access to the network-attached storage device, the hackers encrypt all the files and demand a ransom.
Y'all have several options to cull from to foreclose attacks like this. You can disable remote access birthday, allowing only local connections. If y'all need remote access, you could prepare up a VPN to restrict access to your NAS. And if a VPN isn't a adept choice (because of slow networks, for instance), y'all tin can harden your remote access options.

Option one: Disable Remote Admission
The about secure option y'all tin can cull is disabling remote connexion features entirely. If you can't access your NAS remotely, then neither can a hacker. You lot will lose some on-the-become convenience, but if you lot only work with your NAS at home—to sentinel movies, for instance—then y'all may non miss the remote features at all.
Most recent Synology NAS units include a QuickConnect characteristic. QuickConnect takes care of the difficult work for enabling remote features. With the feature turned on, you lot don't have to fix up router port forwarding.
To remove remote access through QuickConnect log in to your NAS interface. Open the control panel and click on the "QuickConnect" selection nether Connectivity in the sidebar. Uncheck "Enable Quick Connect" then click utilize.
If, however, you enabled port forwarding on your router to gain remote access, you will need to disable that port forwarding rule. To disable port forwarding, y'all should look upward your router's IP address and use it to log in.
And so consult your router's manual to discover the port forwarding page (every Wi-Fi router model is different). If yous don't have your router manual, yous can try a web search for your router model number and the discussion "manual." The transmission will show you where to wait for exiting port forwarding rules. Plough off whatever port forwarding rules for the NAS unit.

Pick two: Use A VPN for Remote Admission
Nosotros recommend just not exposing your Synology NAS to the Internet. Just if yous have to connect remotely, we recommend setting upwardly a virtual private network (VPN). With a VPN server installed, you won't admission the NAS unit of measurement direct. Instead, you lot'll be connecting to the router. The router, in turn, will treat you equally though you were on the same network as the NAS (nonetheless at domicile, for example). It'south worth noting that this blazon of VPN is different than using a VPN service to keep yous safer online or featherbed restrictions—in this example, you're trying to VPNinto your network, non out.
You tin can download a VPN server on your Synology NAS from the Package Center. Just search for "vpn" and choose the install pick under VPN Server. When you first open up the VPN Server, yous'll run across a choice of PPTP, L2TP/IPSec, and OpenVPN protocols. We recommend OpenVPN, as it's the most secure option of the iii.
You can stick with all the OpenVPN defaults, although if you want to access other devices on the network when connected through VPN, you'll need to check "Permit clients to access server'southward LAN" and then click "Apply."
You will then need to ready port forwarding on your router to the port OpenVPN is using (by default 1194).
If you lot're using OpenVPN for your VPN, you'll demand a uniform VPN Client to admission it. We advise OpenVPN Connect, which is bachelor for Windows, macOS, iOS, Android, and even Linux.
Choice iii: Secure Remote Access as Much as Possible
If you demand remote admission and VPN isn't a viable solution (perhaps due to slower net speeds), and so you should secure Remote Access equally much as possible.
To secure remote access, y'all should log into the NAS, open Control Panel, then select Users. If the default admin is turned on, create a new admin user account (if you don't already have 1) and turn the default admin user off. The default admin account is the first account ransomware usually attacks. The Guest user is typically off by default, and you should exit it that style unless you take a specific need for it.
You lot should ensure that whatsoever users y'all created for the NAS accept complicated passwords. We recommend using a password director to assistance with that. If you share the NAS and allow other people to create user accounts, then be sure to enforce strong passwords.
Yous'll find password settings in the Advanced tab of the User profiles in the Command Console. You should check the include mixed case, include numeric characters, include special characters, and exclude common password options. For a stronger password, increase the minimum countersign length to at least eight characters, although longer is better.
To forbid lexicon attacks, a method where an attacker guesses equally many passwords as speedily every bit possible, enable Auto-Cake. This option automatically blocks IP addresses after they judge a sure number of passwords and fail in a short corporeality of fourth dimension. Auto-block is on by default on newer Synology units, and you'll observe it in Control Panel > Security > Account. The default settings volition cake an IP address from making another login endeavor after x failures in five minutes.
Finally, consider turning on your Synology firewall. With a firewall enabled only services you specify as allowed in the firewall will be accessible from the internet. Just go on in listen that with the firewall on, you'll need to make exceptions for some apps like Plex, and add port forwarding rules if yous are using a VPN. Y'all'll find the firewall settings in Control Console > Security Firewall.
Information loss and ransomware encryption is always a possibility with a NAS unit, even when you take precautions. Ultimately a NAS isn't a backup organization, and the best thing you tin do is brand offsite backups of the data. That way if the worst should happen (whether that's ransomware or multiple hard drive failure), you tin restore your data with minimal loss.
