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

Secure data sharing over a business network can be a constant challenge for organizations because it involves dealing with many potential threats during data transfers. Or no critical or confidential info is stolen or misplaced while sharing, it could cost a fortune for an organization to cope with it. So, organizations should know the threats associated with the data transfers within the network along with the countermeasures in order to secure the data.

Open System Adapter Express (OSA-E) is owned by mainframe system that can help you share information through the network securely. In this post, we discuss the possible threats towards the data that's being transmitted in a network and just how OSA-E handles them and enables secure data transmission over the network.

Possible threats to organizational network Intrusion: Intrusion describes an unauthorized entry in to a network and accessing the files and directories of the network. By intruding one system, attacker can 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 obtain connected with the network. Thus, sharing and communication isn't feasible without link with network.

Message modification: Message modification means managing the message or data though it may be being transmitted. The information received through the receiver isn't the same which was sent from the sender.

Traffic monitoring: This means attackers monitoring the events which might be taking place inside the network. They get acquainted with all the information with the network, including confidential data.

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

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

Securing organizational network using OSA Express Open System Adapter Express (OSA-E) is really a physical portion of mainframe that helps your company from possible network threats. OSA-E of a mainframe system connects the system to external LANs (Neighborhood Networks) this means you will be shared one of many systems within the network. It represents internal VLAN involving the devices that are sharing exactly the same OSA-E. VLAN - one physical LAN connection is divided into amount of virtual connections.

OSA prevents network threats by supporting VLAN (Virtual Neighborhood Networks) technology. It secures data in the network by securing virtual networks and network integrity.

Securing virtual networks First, LAN is divided into quantity 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, every time a data is sent in one device to an alternative in the network, OSA attaches that ID and switch directs it strictly to that receiver, it's meant to.

In this manner, OSA-E regulates the transactions across the network properly depending on the VLAN IDs.

Maintaining network integrity Data packets contain "Header checksums" which can be used to verify data integrity. Header checksums aren't but values that are assigned to data packet with regards to the contents of the packet.

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

Conversely, OSA-E helps TCP/IP stack for the receiving side to validate the header checksum from the data packet and compares it together with the checksum value in the event it was sent. If are matching, then no info is lost.E-Business Server

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