Synology NAS and document management system PaperOffice – Network Security

What is a NAS?

A NAS (Network Attached Storage) is a data storage for networks. Like the devices of Synology, the world leader in this field. Together with PaperOffice, the well-known document management system, it forms a functional and very secure entity for a company’s intranet.

There are various providers of storage space in the cloud on the Internet. This benefit, has advantages, but also disadvantages. The biggest disadvantage is undoubtedly the transfer of data into third, in foreign hands. Even if it is promised that the deposited documents are absolutely safe, no company in the world can guarantee this 100%. Not only hackers can compromise data security, depending on the location of the cloud provider, the respective state laws can allow the relevant authorities and companies to completely legalize the content. An unfortunately bad example here is the USA. For example, the renowned computer magazine “c’t” already warned US clouds in April 2017, as their data protection among experts is rated as very low. But even in the EU or in Germany at any time data leaks are possible, either from sloppiness at the operator of the cloud or be it from secret powers of European intelligence.

The reasonable solution for companies is therefore the establishment of an intranet with a common server for all integrated terminals. The NAS forms the heart of the hardware, the central data storage. At the same time, PaperOffice Team is the figurative mind of the company intranet.

The operation of NAS and PaperOffice

The central focus of a data management system such as PaperOffice are logically structured databases whose structure allows maximum security but also lightning fast access.

PaperOffice makes it easy for its users to migrate data previously stored on hard drives of laptops or desktops to a shared data store, the NAS. So all documents of a company are always available and not only if the colleague in question is currently running his computer and allows data access. Of course, hierarchical levels are also possible on the NAS, ie the establishment of different, password-protected access levels.

Databases are used for communication between the computers connected to the network and the NAS. On the side of the terminals, these are mySQL databases, in which all information is stored that will later move to the NAS. This can be data from the hard disk as well as scanned documents to digitize analog formats as well. If a NAS-based intranet is already set up, the paperless office should also be realized. It’s easy with PaperOffice.

From the mySQL database, the information stored here is transferred to the database on the NAS. This is the database management system MariaDB 10, which is used by PaperOffice as well as Synology.


Safety first

As soon as you save the data in the mySQL database, they are encrypted using an AES 1024-bit key. This extremely secure encryption was originally used for military purposes. A second level of security refers to Windows operating systems. Usually, a data directory is created under these operating systems when saving. For example, this allows espionage software to gain insight into what has been stored. Quite a table of contents for thieves. Windows cannot create a data directory under PaperOffice and Synology NAS.

Once all the data in MariaDB 10 has arrived on the NAS server, PaperOffice manages it according to the wishes of the user. Safe and with access speeds that are literally lightning fast.

PaperOffice is available in 4 languages, such as English, German, Spanish and Russian. Also offers a 14-day free trial period
