Tips to protect a NAS from ransomware attacks

NAS protection against ransomware attacks

Ransomware  is currently one of the most prominent threats on the web due to its ease of propagation. In addition, its dangerous ability to restrict access to certain parts or files of the infected system in exchange for a ransom to lift the restrictions also makes it one of the most powerful.

In the beginning many of the attacks were among users, but the ransomware threat has evolved to focus mainly on companies of all sizes.

In recent months there has been a wave of ransomware attacks on NAS devices, precisely because these network storage devices are a highly desirable target.

NAS protection against ransomware attacks

Don’t be the next victim and protect your data! Follow these tips that we offer you on the Globenet International blog, so that you can be prevented.

Keep your software up to date: It is not for nothing that manufacturers systematically release security patches and updates. Having these firmwares (operating systems and antivirus) correctly updated with their latest versions is an excellent security measure. This step alone certainly does not prevent an attack, but when they are designed to evade traditional protections they are an important component of comprehensive security. Remember to always keep your antivirus up to date, it is not a bad thing to do and this helps you to protect your organization.

Make regular NAS backups: This is perhaps one of the most useful tips. Ransomware attackers always ask for a ransom to give their victims back control of their computers, but if youkept making regular backups you won’t have to pay any ransom. It is true that with all the conveniences of having storage in the Cloud many companies forget to make backup copies of files and data, but whenever possible it is necessary to do so. We remind you that you can do so manually, but it is much more comfortable and safer to automate this process.

Multi-layer systems: You must not forget to use multi-layer security systems with advanced threat prevention technologies. Experts say that a multi-layered security system is the best way to defend against ransomware and the damage it can cause. Of course, it is never too much to continue using traditional protections, such as antivirus and IPS, but companies need to incorporate additional layers to deal with new types of malware.

Disable online access to the device: This is logically a bit inconvenient, but if we do not need to connect remotely, it can be a very valuable option.

Disable the SMB protocol: This measure goes directly against cybercriminals who will not be able to encrypt the NAS with their ransomware attacks through the local network. 

Strengthen your passwords: Although this advice seems somewhat repetitive, it is by no means negligible. Any attack can start if we have a vulnerable password. Always remember to apply it to any type of device. A strong and complex password, using combined patterns of letters, symbols and numbers will be much better.
