It's time for the next installment of our series on living with NAS. QNAP TS-253A. We have already written seven articles in which we have gradually introduced many functions, features and other interesting things related to this particular NAS. However, we have not yet addressed security at all, and today's article will be about this issue.

If you buy a NAS for your home, we assume that you will use it extensively. This means that the device will have the highest possible uptime, you will use it miniIt will be able to turn off and perform user-specified tasks in one go. Given such intensive use, it is not out of place to properly secure the NAS. It is expected that users will store large amounts of sensitive data on it, and the level of security should correspond to this. If you store your private photos, videos on the NAS, or if you are an even bigger power user and use the NAS for work tasks, for example, or have a server built on it for your business, you should not take security lightly.

There is a default antivirus protection in the system with a simple and striking name "Antivir". It works basically the same as Windows Defender, which is included in every operating system installation since Microsoftu. It runs in the background by default and checks incoming and outgoing activity. It has a very decent frequency of updates, which appear several times a month. However, this similarity with Microsoft It doesn't end with Defender. Like Defender, the built-in Antivirus is relatively undemanding and consumes almost no resources in normal mode.

The control is very easy, all manipulation is done by clicking through the main menu. In the settings you can search (or manually enter) updates, set the frequency of searching for updates, etc. Other tabs (see photo gallery) are already dedicated to the tasks themselves. You can specifically set the directories for which you want to perform a separate check. You also set the frequency with which this check task should be performed, how (max(minimum) large files will be scanned by the antivirus and last but not least, what should be done with infected files. All scan tasks are listed in the list next to where you can view them and modify their parameters as you wish. The last tab is the quarantine, which will contain all detected suspicious files. In the quarantine, you can continue to work with them as you wish.

As Windows Defender is not the only option to protect your computer, nor is the default antivirus in the NAS the only possible option. There are several alternatives in the application catalog that supplement the default solution in some way or completely replace it. The most popular applications in the catalog are, for example, the Malware Remover application, which, as the name suggests, helps with the removal of malicious malware. Another constant in the menu is the antivirus from the infamous company McAfee. However, it is questionable to what extent this is a real antivirus, or is it more of a form of malware/spyware.

As with classic computers (and Macs), if the user does not click on suspicious links or visit suspicious websites, they should not have to worry about any viruses or malware/spyware. The built-in antivirus should probably be the most reliable varianta, as virus definitions are managed by QNAP himself and safety engineers QNAPshould be most aware of potential security gaps in their own systems. A certain level of protection and a kind of first wall can be the connection to the web itself through a well-configured router. Then you just need to use your brain and the operation of the NAS should be without problems.
