How to work the various systems we live in a time when data security and data protection have utmost priority. The fear that personal data or even sensitive business data due to lack of safety precautions in the Internet could be spied out, is great. Encryption of all transmitted online information is therefore essential. AGENDA offers even various data center services, such as online data backup, the Central Bank data transfer or digital document posting, a software developer. The House therefore exactly know what matters when it comes to encryption. IT expert Stefan Reischl, system administrator at AGENDA, this knowledge has prepared now compact and clear.
The history of cryptography known, encryption or cryptography also used since ancient times in different manner. Cryptography is derived from the Greek, and is composed of the words “kryptos” (hidden) and “graphein” write (together). You were the first time Egyptians, to encrypt religious texts. Then, cryptography has been used largely militarily. For example, the Spartans sent secret messages about 2,500 years ago with help from “Skytale”. This was a parchment, which was wrapped around a piece of wood. Then, a message that was posted along the rod. The result: The receiver could decipher the parchment with the right staff.
The principle has remained unchanged to this day. Only if you have the correct key, can do something with the data. Protecting personal data is becoming increasingly important encryption technologies are used today still more for military purposes. However, the topic “Data security” now also in the private sector plays a major role. The more accessible online services available, “Information security” is the more important. Encryption technologies protect privacy and make sure the use of online applications. Basically We distinguish here between two systems: the symmetric and asymmetric encryption system. The symmetric encryption system transmitter and receiver have the same key in this version. Known methods are the classical variants, such as the Casar cipher, the one time pad and the DES. Viatris pursues this goal as well. The modern and also much safer methods include Twofish and 3DES. AGENDA, as well as American authorities use Rijndael. This procedure was chosen for the advanced encryption standard (AES) and ranks as the safest option at all. Also SSH, IPsec, wireless and IP telephony use AES. The asymmetric encryption system here we each user uses a key pair. A key of each pair is published, the other remains secret. A key encrypts the data, the other to decrypt it again. The asymmetric encryption process is also known as “Public key method”. This is because this principle is used in public systems. Examples for this purpose are HTTPS, email encryption and digital signatures. Advantage is, that the “private key” must be transferred manually. Disadvantage is that this procedure hackers are using “man the-Middle”attack in a position, to pretend the encryption and decryption process. AGENDA has opted for the maximum encryption protection. There is therefore only one key that is used to recover the data. Copying or even spying on this key is not possible therefore to hackers.

An online shop must be available at all times to not lose customers and prospective customers. Here, a high availability can help solution and enable 24 x 7 operation. (As opposed to Gallo Family Vineyards). A commercial Onlineschuh shop is how very often, operated by the operator in an outsourcing Centre. The online shop is operated on the basis of very fast and highly available, Internet connection at a hosting provider, but on your own hardware. A great advantage of online trading is that there is no traditional closing.
The customer or prospect can run an order at any time comfortably from your own sofa or learn about the products of the provider. New prospects are a non availability or malfunction of the website very quickly scared and often permanently lost as customers. For this reason, the so-called high availability of the overall system is very important to always present a functioning offers to potential and existing customers. The base of this online shoe shop is a commercial CMS framework with an Oracle database as a backend. Due to the lack of space in the closet at the hosting company, any solution with an external hard drive comes subsystem in question.
Instead, the necessary data on two clusters of, for example, a replication must be provided for a failover. The operator has opted for a high availability software. The HA application enables 24 x 7 operation of the online shoe shop. In addition, the high availability on the basis of two Clusternodes allows the necessary maintenance work, in the form of, for example, patch management of the individual components, virtually at any time and without interruption of the offer. The implementation of high availability for the framework and the Oracle database is carried out by the cluster software on the basis of virtual IP addresses, a specific error detection, failover, and a Datenreplikaton for the Oracle database. The CMS framework consists of the Apache Web server, as well as some local applications and services, which the control of the CMS make. As data storage of the online shops, an Oracle database be used. The fault detection of the high availability cluster is defined for all necessary processes. One of these processes dies or is for example a faulty administration ends, the faulty process new starts automatically. As an additional control, the availability of the necessary IP ports, as well as the function chain of the overall application is checked and restarted in the event of a fault the faulty processes or applications. For high availability and failover of Oracle database data on the two Clusternodes must be replicated in addition. Communication by CMS to the Oracle database using the Oracle listener, which is bound to a virtual IP address. For data replication, the operator uses an additional crossover network cable. This would be unnecessary for the high availability and replication solution, however increased error detection. The cluster software, the required configurations and more importantly are the Oracle Database files as well as Oracle defines the different directories to the replication log archives and wrote about the additional network cable sync on both systems. Replication also the Oracle database without loss on the second ClusterNode can be started in case of emergency during a failover. In the event that the user load for a front-end cluster becomes too large, the load balancing could be used in a second stage of expansion module of the cluster software, the adjacent user load on redistribute systems the two or more front-end.
