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

Secure data sharing over an enterprise network is often a constant challenge for organizations mainly because it involves managing many potential threats during data transfers. Or no critical or confidential details are stolen or misplaced while sharing, it might cost a fortune for an organization to cope up with it. So, organizations should become aware of the threats from the data transfers within the network and also the countermeasures in order to secure the data.

Open System Adapter Express (OSA-E) is associated with mainframe system that assists you share information through the network securely. In this article, we discuss the potential threats on the data which is being transmitted in the network and exactly how OSA-E handles them and enables secure data transmission over the network.

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

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

Message modification: Message modification means manipulating the message or data even though it is being transmitted. The info received through the receiver is not the same which was sent through the sender.

Traffic monitoring: This means the attackers monitoring the events which are taking place inside the network. They familiarize yourself with all the information in the network, including confidential data.

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

All these are the five possible and the most common threats for any network. Some of these threats might be avoided through the use of individual physical connections between every communicating system; nevertheless it will be very expensive, for big organizations.

Securing organizational network using OSA Express Open System Adapter Express (OSA-E) can be a physical a part of mainframe that helps your organization from possible network threats. OSA-E of the mainframe system connects the machine to external LANs (Local Area Networks) also it can be shared one of many systems within the network. It acts as internal VLAN between the devices which can be sharing exactly the same OSA-E. VLAN - one physical LAN connection is split into amount of virtual connections.

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

Securing virtual networks First, LAN is split into number of virtual connections or VLANs every VLAN contains an ID. Switch, which is often used to set up LAN network knows all VLAN IDs. So, whenever a data is sent in one device to another in the network, OSA attaches that ID and switch directs it strictly compared to that receiver, it can be meant to.

Like this, OSA-E regulates the transactions throughout the network properly depending on the VLAN IDs.

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

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

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

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