This article is not speci\u00adfi\u00adcally about secu\u00adrity in NeuroomNet, but, since NeuroomNet is a web-based tool, about the secu\u00adrity of web-based tools in general. In other words, what you should consider opera\u00adting a system like NeuroomNet secu\u00adrely. We are happy to help you with any ques\u00adtions you may have, but you can get some ideas below about what to consider.<\/p>\n<\/div>\n

Secu\u00adrity is a double-edged sword: If the secu\u00adrity is too high, the autho\u00adrized user is so massi\u00advely hindered in the tasks that accep\u00adtance suffers signi\u00adfi\u00adcantly. But if it is too low, this can lead to very serious conse\u00adquences.
In this respect, the internet is once again both a curse and a bles\u00adsing.
The disse\u00admi\u00adna\u00adtion of know\u00adledge is a great strength, but with it, the know\u00adledge of how to under\u00admine a system\u2019s secu\u00adrity is also quickly spread. Just as the connec\u00adtion to the internet itself creates the possibility of being able to conve\u00adni\u00adently attack a system. On the other hand, certain subsys\u00adtems can be auto\u00adma\u00adti\u00adcally kept up to date via the internet and protected from harmful influences.
So if you want to be on the safe side, you have to move with the times and adapt your system to the constantly incre\u00adasing requi\u00adre\u00adments. There are areas where you can take a brea\u00adther because the concept already provides a great deal of secu\u00adrity. Other areas adapt auto\u00adma\u00adti\u00adcally (if there is access to the internet) and finally, there are areas where you have to regu\u00adlarly check whether ever\u00ady\u00adthing is working as intended or react appro\u00adpria\u00adtely.<\/p>\n<\/div>\n

A very successful and long-lasting method is to encrypt the commu\u00adni\u00adca\u00adtion between two parties. This means that an atta\u00adcker can neither draw conclu\u00adsions nor get hold of the actual data. Anyone who wants to read this data has to make an enormous effort and has a much easier time, for example, at the end points of the commu\u00adni\u00adca\u00adtion, i.e. before it is encrypted\/decrypted. Because modern encryp\u00adtion still cannot be cracked in short periods. This means that data can then also be trans\u00admitted via connec\u00adtions that run over the internet, WLAN, mobile radio, or other publicly visible networks without a guilty consci\u00adence. And thanks to sophisti\u00adcated mecha\u00adnisms for estab\u00adli\u00adshing the encryp\u00adtion, the user does not even notice this in the best case and is not disturbed by the daily routine. Except when a time limit for rene\u00adwing a secure connec\u00adtion has expired. Because one aspect of secure commu\u00adni\u00adca\u00adtion is to renew the under\u00adlying keys so that the lengthy attacks remain unsuc\u00adcessful.<\/div>\n

Another aspect of a long-lasting secu\u00adrity concept is the protec\u00adtion of endpoints by fire\u00adwalls. A fire\u00adwall is a secu\u00adrity system that protects a computer network and individual compu\u00adters from unwanted network access. In short, a modern system must be able to handle encrypted commu\u00adni\u00adca\u00adtion and protected networks. If the front door and windows in your house were the fire\u00adwall, then the safe where you store your most valuable things would be the encryp\u00adtion.<\/div>\n

A prere\u00adqui\u00adsite for encryp\u00adtion is the possibility of secu\u00adrely sending the keys to legi\u00adti\u00admate parti\u00adci\u00adpants and regu\u00adlarly updating them. This is done with the help of so-called certificates. A certi\u00adfi\u00adcate can use a signa\u00adture to make it credible by whom, for whom, and until when it was issued. A distinc\u00adtion is made between whether a certi\u00adfi\u00adcate must be publicly acces\u00adsible or whether it is used within a closed system. The under\u00adlying tech\u00adno\u00adlogy, and thus the secu\u00adrity, is iden\u00adtical for both vari\u00adants.<\/div>\n

For public appli\u00adca\u00adtions with publicly acces\u00adsible certificates, specia\u00adlized compa\u00adnies are used. These only issue certificates through veri\u00adfied appli\u00adca\u00adtions that are subject to a fee. Such a certi\u00adfi\u00adcate can then be used for a certain period to secure one\u2019s systems and does not require any special prepa\u00adra\u00adtion on the compu\u00adters that already know the issuer.
The dura\u00adtion of such a certi\u00adfi\u00adcate is curr\u00adently limited to 2 years and is even to be shor\u00adtened to 13 months.<\/div>\n

For internal appli\u00adca\u00adtions, a self-issued certi\u00adfi\u00adcate can be used. When issuing these certificates, certain limits can be exceeded to reduce the frequency of admi\u00adnis\u00adtra\u00adtive work. For such internal appli\u00adca\u00adtions, however, an admi\u00adnis\u00adtra\u00adtion of these certificates must first be estab\u00adlished and the issuer must be made known to the parti\u00adci\u00adpants. This enables the users (or compu\u00adters) to check whether a certi\u00adfi\u00adcate is (still) valid or to be provided with a new certi\u00adfi\u00adcate. Often both certi\u00adfi\u00adca\u00adtion systems (internal and external) are used to keep the effort for the users as low as possible or because it is tech\u00adni\u00adcally neces\u00adsary.<\/div>\n

<\/p>\n

To ensure that ever\u00ady\u00adthing func\u00adtions as smoothly as possible, a so-called PKI (private key infra\u00adstruc\u00adture) must be estab\u00adlished. This helps with admi\u00adnis\u00adtra\u00adtion and control and can auto\u00admate individual aspects. There are diffe\u00adrences due to the manu\u00adfac\u00adtu\u00adrers used in each case. It also requires appro\u00adpria\u00adtely trained staff to set it all up and renew it every few years or months, as described above. The regular instal\u00adla\u00adtion of renewed certificates must be ensured, as they cannot replace them\u00adselves.
The more complex a system becomes, the greater the need to set up a sepa\u00adrate certi\u00adfi\u00adca\u00adtion autho\u00adrity and PKI. The days of \u201cwe just plug ever\u00ady\u00adthing into the network switch\u201d are over, because other\u00adwise anyone can connect to the connec\u00adtion, read ever\u00ady\u00adthing along with the login data, and even mani\u00adpu\u00adlate it during use (see also man-in-the-middle attack).<\/p>\n

Today, it is impos\u00adsible to imagine networks such as the Internet (World Wide Web) and intra\u00adnets (local networks\/WLAN) without secu\u00adring data connec\u00adtions<\/strong>. Almost ever\u00adyone has heard the names of the proto\u00adcols used for protec\u00adtion. Nevert\u00adheless, it is probably not clear to ever\u00adyone what the diffe\u00adrence is between SSL, TLS, and HTTPS and what secu\u00adrity proper\u00adties these proto\u00adcols have.<\/div>\n

Let\u2019s assume a user wants to control an exhibit in NeuroomNet. When using a secured connec\u00adtion, this user bene\u00adfits from the secu\u00adrity features of encrypted and secured commu\u00adni\u00adca\u00adtion. Without encryp\u00adtion, data that is trans\u00admitted can be read as plain text by anyone who has access to the corre\u00adspon\u00adding network. With the incre\u00adasing spread of open (i.e. unen\u00adcrypted) WLANs, the importance of HTTPS is growing because it allows content to be encrypted regard\u00adless of the network used. Encryp\u00adtion makes it impos\u00adsible for third parties to see, among other things, exactly which pages of a website have been visited.
By using certificates, it can be ensured that no mani\u00adpu\u00adla\u00adtion of the content by third parties is possible during trans\u00admis\u00adsion and, for example, that no false information about your company is injected into your company website.<\/div>\n

TLS stands for Trans\u00adport Layer Secu\u00adrity<\/strong> and is the successor protocol to SSL 3.0. The first version 1.0 of TLS is a slightly modi\u00adfied variant of the third version of SSL and was stan\u00addar\u00addized by the IETF.<\/p>\n

The Internet Engi\u00adnee\u00adring Task Force (IETF)<\/strong> is an orga\u00adniza\u00adtion that deals with the technical deve\u00adlo\u00adp\u00adment of the Internet to improve its func\u00adtio\u00adning. Curr\u00adently, TLS is in version 1.3 and is now also in wide\u00adspread use.
TLS consists of two main compon\u00adents: TLS Hand\u00adshake and TLS Record. In TLS Hand\u00adshake, secure key exch\u00adange and authen\u00adti\u00adca\u00adtion take place. TLS Record then uses the symme\u00adtric key nego\u00adtiated in TLS Hand\u00adshake for secure data trans\u00admis\u00adsion \u2014 the data is encrypted and trans\u00admitted with a MAC protected against changes.<\/p>\n<\/div>\n

MAC stands for Message Authen\u00adti\u00adca\u00adtion Code<\/strong> and is used to obtain certainty about the origin of data or messages and to verify their inte\u00adgrity. MAC algo\u00adrithms require two input para\u00adme\u00adters, firstly the data to be protected and secondly a secret key, and calcu\u00adlate a checksum from both, the Message Authen\u00adti\u00adca\u00adtion Code.

HTTPS is used to estab\u00adlish confi\u00adden\u00adtia\u00adlity and inte\u00adgrity in the commu\u00adni\u00adca\u00adtion between the NeuroomNet server and the web browser (client) in the network. HTTPS refers to the use of HTTP via SSL (TLS). The use of HTTPS can be reco\u00adgnized in the browser by the fact that the visited Internet address is preceded by https instead of http. In addi\u00adtion, most modern brow\u00adsers high\u00adlight a secure connec\u00adtion visually.
A secure connec\u00adtion is often equated with encryp\u00adtion of the connec\u00adtion. However, SSL\/TLS offers additional secu\u00adrity features.
Accor\u00adding to the original inter\u00adpre\u00adta\u00adtion, the client browser should first display the certi\u00adfi\u00adcate to the user after selec\u00adting the HTTPS address. The user then decides whether he trusts the certi\u00adfi\u00adcate for this session, possibly saving it perma\u00adnently, if neces\u00adsary after checking it via the speci\u00adfied links. Other\u00adwise, the HTTPS connec\u00adtion is not estab\u00adlished (\u201cLeave this page\u201d with Firefox or \u201cClick here to leave this page.\u201d with Internet Explorer).<\/div>\n
