In my understanding LUN security starts in step by step 1) In Storage Array 2) In Fabric Switch Zoning 3) Using a Host software LUN Security in a Storage Array: Lun (Logical Unit Number) Security starts in Storage array through 1) Registering HBA in a storage array. 2) In Raid Group (for Data security) 3) Lun Masking: Registering HBA in a Storage Array: A SCSI cable or a fiber channel cable is connected to the storage array front end port directly from the HBA card or through the Fabric switch. We can register a HBA in a manual way or storage array host agent will automatically identify the HBA WWN number. For every storage array there will be fail over mode to avoid single path outages. By registering the HBA’s in a storage array no other can access the data from the array except the Hosts. When a lun is mapped using the WWN number with the storage array front end ports and with the HBA wwn. In mapping, server can see the storage lun through HBA WWN and storage front end port which were in the mapping. Server team can identify the LUN using its unique number for mounting the drive in the server. To mount the lun in server, server should be rebooted or should scan using host software (power path). Even though if the storage node is moved still the server can see the storage using other storage nodes added in the mapping. When installing or making changes more number of server then we need to be extra cautious. We need to be careful while adding the HBA wwn and storage front end ports to the mapping. Sometimes rough servers don’t support and coordinate with the remaining servers. The solution for this type of problem is with masking. Creating a storage group and adding the lun, HBA, Front end port to it. Raid Type: Lun data... ... middle of paper ... ... is done using the node wwns. HBA node wwn and storage node wwn is used for doing zoning. We can add additional HBA node wwns if we want server to see the storage array. Hard zoning is more secure when compared with soft zoning. But soft zoning is more flexible. Security using Host software: Host software like power path is used for managing multipathing and HBA node. It manages the paths between storage array to server HBA, it also does the load balancing. By using the power path or any other host software we can save the loss of data and can maintain continuous data flow without any rick even after a path gets failed. Conclusion: The main problem facing in a one to one or one to many connection SAN environment is the Data secure. By implementing these methods with careful study will solves and secure by providing 99.99% security for the LUN data protection.
Since the Council meeting on March 31, the issue has become both more contentious and complicated. The Council voted on September 1 to rescind their approval of the new zoning. However, the developer submitted their proposed plans for the site a day prior, which under a new state law, allows for the retail zoning to stand. The “time of application” l...

The authorization role is used by providers that make access decisions for the requested resources based on the effective user identity context. This identity context is determined by the authentication provider and the identity assertion provider mapping rules. Evaluation of the identity contexts user and group principals against a set of access policies is done by the authorization provider in order to determine whether access should be granted to the effective user for the requested resource [14]. Out of the box, the Knox Gateway provides an ACL based authorization provider that evaluates rules that comprise of username, groups and ip addresses. These ACLs are bound to and protect resources at the service level. That is, they protect access to the Hadoop services themselves based on user, group and remote IP address [14]. To provide a common authorization framework for the Hadoop platform, providing security administrators with a single administrative console to manage all the authorization policies for Hadoop components is the goal of Hadoop’s developers.
The next step is to set the names of the devices on the network and edit their attributes.

A network can be based on either a peer-to-peer level or server-based, also referred to as domain-based. To distinguish the difference, a peer-to-peer network, also known as a workgroup, is a network in which a group of computers are connected together to share resources, such as files, applications, or peripherals. The computers in a peer-to-peer network are peers to one another, meaning no single computer has control over one another. There is also no central location for users to access resources, which means that each individual computer must share their files in order for other computers to have access (Muller, 2003, p.411). “In a peer-to-peer environment, access rights are governed by setting sharing permissions on individual machines.” (Cope, 2002) On the other hand, in a domain-based network, the computers connected together are either servers or clients. All of the other computers connected to the network are called client computers. The server is a dedicated machine that acts as a central location for users to share and access resources. The server controls the level of authority each user has to the shared resources. When logging on to the network, users on client machines are authenticated by the server, based on a user name and password (Lowe, 2004, p.13).
With remote storage systems hackers can secretly backup files from computers and can access them later. It creates the possible theft of hackers sending virus out, stealing confidential and personal information from others.
The cloud storage services are important as it provides a lot of benefits to the healthcare industry. The healthcare data is often doubling each and every year and consequently this means that the industry has to invest in hardware equipment tweak databases as well as servers that are required to store large amounts of data (Blobel, 19). It is imperative to understand that with a properly implemented a cloud storage system, and hospitals can be able to establish a network that can process tasks quickly with...
In conclusion, a local area network is made up of computers and a myriad of devices, such as routers, servers, switches, and firewalls. In order for it to connect to the Internet, a router must be installed. Servers provide special functions such as printing, file sharing, etc. Switches connect the computers together from different parts of the network. Firewalls prevent unauthorized access. There are a host of other devices that may be used as well. These devices are hubs, gateways, repeaters, wireless access points,
...re to unauthorized individuals or system. For example, credit card information or bank account number of a client in a bank should not be exposed to unauthorized people. The data can be encrypting confidentially by hiding plain text data. Other than that, data should be protected from deletion or modification by unauthorized users in an organization. This is because any changes may cause unrevealed damage to the organization. Data integrity can only be achieved by hashing mechanism. Availability of data accessibility in an organization should be guaranteed by backup system or network hardening mechanisms. All the systems, channels, and mechanism should be working properly to ensure the information needed is always available. Highly available networks are designed to manage multiple network connection and deal with potential problems such as denial of service attack.
There are reasons for going with the client-server architecture for the new MHC-PMC because of the requirements. The MHC-PMC will need to be accessed by different clinics in the area. One of the reasons for using the client-server is to access shared database from ...
In simple terms, it's just a storage located remotely which you can access anywhere. It's like storing your files online and accessing it anywhere while using your laptop, mobile device or another PC.
They have made six assumptions when designing GFS. First, the system should be able to detect, sustain and recover from components failures. Second, larger files is the trend today and should be managed effectively. Third, read operations are performed many times so they should consider sorting the small reads to enhance performance. Fourth, the trend now is writing large files that are usually not modified but appended so they consider appending operation instead of updating or overwriting. Fifth, since multiple clients could read from the same file at the same time, there should be defined semantics for that. Sixth, they considered that high stable bandwidth is more importa...
