How Open System Adapter Express (OSA-E) Secures Your small business From Network Security Threats

Secure data sharing over a business network is often a constant challenge for organizations since it involves working with many potential threats during data transfers. If any critical or confidential details are stolen or misplaced while sharing, it could cost a fortune for an organization to cope on top of it. So, organizations should be aware of the threats for this data transfers on the network and the countermeasures in order to secure the information.

Open System Adapter Express (OSA-E) is owned by mainframe system that helps you share information across the network securely. In this post, we discuss the possible threats for the data that is being transmitted within a network and the way OSA-E handles them and enables secure data transmission over the network.

Possible threats to organizational network Intrusion: Intrusion refers to an unauthorized entry right into a network and accessing the files and directories in the network. By intruding one system, attacker can access the data and files using their company devices that are connected to the same network.

Denial of service: Denial and services information or DoS means not allowing a person or a system to get connected with the network. Thus, sharing and communication is not possible without connection to network.

Message modification: Message modification means managing the message or data while it's being transmitted. The info received by the receiver isn't the same that was sent from the sender.

Traffic monitoring: This refers back to the attackers monitoring the events which are taking place in the network. They become familiar with all the information of the network, including confidential data.

Impersonation: Impersonation describes changing the sender's address within the packet (information is usually transmitted by means of packets within a network) and misleading the receiver/receivers.

All these are the five possible along with the most common threats for any network. Many of these threats might be avoided by using individual physical connections between every communicating system; but it will be very expensive, for even big organizations.

Securing organizational network using OSA Express Open System Adapter Express (OSA-E) is often a physical portion of mainframe that helps your company from possible network threats. OSA-E of an mainframe system connects the machine to external LANs (Geographic area Networks) therefore it may be shared among the systems in the network. It acts as internal VLAN involving the devices which can be sharing the same OSA-E. VLAN - one physical LAN connection is split into number of virtual connections.

OSA prevents network threats by supporting VLAN (Virtual Specific geographic area Networks) technology. It secures data in a network by securing virtual networks and network integrity.

Securing virtual networks First, LAN is divided into quantity of virtual connections or VLANs every VLAN contains an ID. Switch, that is utilized to set up LAN network knows all VLAN IDs. So, each time a data is sent from one device to a new in the network, OSA attaches that ID and switch directs it strictly to that receiver, it really is meant to.

In this way, OSA-E regulates the transactions through the network properly based on the VLAN IDs.

Maintaining network integrity Data packets contain "Header checksums" which might be used to verify data integrity. Header checksums aren't but values which are assigned to data packet based on the contents of the packet.

OSA-E helps TCP/IP stack about the sending side to calculate the header checksum value and attaches it on the data packet that you should sent to the receiver.

However, OSA-E helps TCP/IP stack on the receiving side to validate the header checksum of the data packet and compares it with the checksum value when it was sent. If both are matching, then no details are lost.E-Business Server

In this way, OSA Express secures the info from being lost, unauthorized access and manipulation of data that is being transmitted from the network.
