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

Secure data sharing over an organization network is a constant challenge for organizations since it involves managing many potential threats during data transfers. If any critical or confidential data is stolen or misplaced while sharing, it might cost a fortune for a business to cope up with it. So, organizations should know about the threats from the data transfers on the network and also the countermeasures in order to secure the data.

Open System Adapter Express (OSA-E) is assigned to mainframe system that helps you share information over the network securely. In this article, we discuss the potential threats towards the data that is being transmitted inside a network and how OSA-E handles them and enables secure data transmission through the network.

Possible threats to organizational network Intrusion: Intrusion describes an unauthorized entry in to a network and accessing the files and directories from the network. By intruding one system, attacker are able to access the data and files using their company devices which are connected to the same network.

Denial and services information: Denial and services information or DoS means not allowing an end user or a system to have connected with the network. Thus, sharing and communication isn't feasible without link to network.

Message modification: Message modification means managing the message or data though it may be being transmitted. The information received through the receiver is not same that has been sent from the sender.

Traffic monitoring: This refers to the attackers monitoring the events which are taking place inside the network. They get to know all the information with the network, including confidential data.

Impersonation: Impersonation refers to changing the sender's address from the packet (data is usually transmitted available as packets in a network) and misleading the receiver/receivers.

The above mentioned are the five possible as well as the most common threats to your network. Some of these threats could be avoided through the use of individual physical connections between every communicating system; nonetheless it will be very expensive, for even big organizations.

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

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

Securing virtual networks First, LAN is divided into amount of virtual connections or VLANs each VLAN contains an ID. Switch, which is often used to set up LAN network knows all VLAN IDs. So, when a data is sent derived from one of device to a new in the network, OSA attaches that ID and switch directs it strictly fot it receiver, it is meant to.

In this manner, OSA-E regulates the transactions over the network properly in line with 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 that are assigned to data packet depending 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 for the data packet that ought to be sent to the receiver.

On the other hand, OSA-E helps TCP/IP stack on the receiving side to validate the header checksum of the data packet and compares it using 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 your data from being lost, unauthorized access and manipulation of internet data that is being transmitted from the network.
