We are now living in a digital world where our precious pictures, favorite music, and personal files are saved on our devices. Data storage means a lot nowadays. 


Storing data can be challenging especially because of security concerns. You need to protect your data and businesses need to protect confidential client information from data theft-- this is where Network Attached Storage comes in.


What is Network Attached Storage?

Network Attached Storage

Network Attached Storage or NAS is a data storage solution that helps handle file sharing on personal, academic, or business networks.


NAS makes it easier for businesses to share files between different members and departments and it is a simpler alternative to standalone servers.


This data storage solution is optimized to deliver at the fastest possible speed. Users can connect to NAS devices without using separate server setups or different hard disks.


Is NAS Safe for Personal and Business Use?


Your network is as safe as you make it to be-- it depends on many factors.


You need to consider what NAS model and operating system you are using. You also need to consider whether if your NAS has all the necessary security updates.


Another point for consideration is whether you or the team are well-aware of the best practices to ensure optimal network safety. For instance, even if your NAS is relatively safe, opening too many ports can give way for intruders to gain access to your information.


Common NAS Security Issues


As mentioned previously, NAS is as safe as you make it to be-- that said, here are some common security issues you should look out for:


Password Security


Most NAS security systems have authentication procedures incorporated in them. Passwords are great, but if you solely rely on password security or other forms of authentication-- they can be a threat in their own right.


You need to make sure that your password is strong. It should not be something people can easily guess. Another issue with just relying on authentication as security is the fact that some cybercriminals have digital tools that can bypass.


Do not be complacent and make sure that you change default passwords into stronger ones.


Data Leakage from Network Devices


Users can directly or indirectly connect to NAS servers. Usually, it only involves computers on the same network, but nowadays, smart devices connected to the IoT or Internet of Things can also join the server.


Security experts have raised red flags regarding the IoT-connected devices being possibly targeted by hackers, who can use those devices to spread malware across corporate networks.


Malware and Viruses


If your NAS server is not equipped with enough security measures, it can be exposed to malware and viruses. Cybercriminals can breach your security through IoT-enabled devices or through other means that may involve employees falling victim to malicious schemes. 


Command Injection


What is command injection? This method allows unauthorized attackers to take control of Network Attached Storage drives. Command Injection gives hackers access to root privileges that only network administrators should possess.


Tips for Better NAS Security to Protect Your Data

NAS security

Network Attached Storage creates a safe space for businesses and their employees to store and share files. It is a convenient and cost-efficient storage solution for both individuals and businesses alike. 


However, it not 100% safe. It is the responsibility of both administrators and each user to keep the servers safe from malicious attackers.


Here are some NAS security tips for keeping your data safe:


Require strong passwords.


Cybercriminals can breach company NAS security through weak security among the people who use the networks. Make sure that to audit the security skills of your team and ensure that the standards remain high.


You should set up password rules to make sure that everyone uses strong passwords. You should also encourage or require two-factor authentication (2FA) for an added layer of security.


Update NAS firmware regularly.


Although security software and tools continue to improve, cybercriminals can also improve on their methods. An outdated NAS operating system can be prone to malicious attacks and security breaches.


Do not ignore reminders or notifications for firmware updates. Make sure that you install them as soon as they are available to prevent allowing cyber-attackers to get into your system. 


Do not use default administrator accounts.


Do not make your login process obvious to cybercriminals. Choosing an easily identifiable account gives hackers opportunities to take over and infiltrate your servers.


Secure your connection and ports.


Enable HTTPS ports instead of HTTP to help secure incoming and outgoing traffic. You also need to assess the FTP connection and make sure that it is safe.


Close all the ports that you do not intend on using for communication outside. You can also change the default ports to reduce the number of attacks on your NAS.


Enable the NAS firewall.


Most NAS systems have firewalls. Make sure that your firewalls are enabled. There is absolutely no reason for anyone to turn it off.


The NAS firewall registers legitimate users and denies access to unauthorized visitors. It is a powerful first line of defense against attackers.


Enable DoS protection.


Make sure that your NAS denial-of-service (DoS) attack protection is enabled. This feature is not enabled by default as it may trigger a false positive where your NAS thinks that legitimate traffic is a DoS attack.


You need to whitelist known traffic sources first, then keep the DoS protection on.


Use a VPN while using NAS.


VPN is a great NAS security tool. It adds a layer of encryption to online traffic that goes through your network and the internet.


VPN prevents anyone from obtaining or tracking your information like password details or IP addresses.


Bottom line


Your Network-Attached Storage can be a safe space where you can store important data, files, and information. However, it cannot stay safe and secure on its own. 


Each user that benefits from the NAS share the responsibility of keeping it safe. Use strong passwords, update firmware, and make sure you properly utilize security tools to protect your servers which in turn keeps your data safe.
