  Information Security Framework

  The basic information security framework is built to achieve four security goals, confidentiality, integrity, and availability (CIA) along with accountability. This framework incorporates all security standards, procedures and controls, required to

  mitigate threats in the storage infrastructure environment.

  Confidentiality: Provides the required secrecy of information and ensures that only authorized users have access to data. This requires authentication of users who need to access information. Data in transit (data transmitted over cables) and

  data at rest (data residing on a primary storage, backup media, or in the archives) can be encrypted to maintain its confidentiality. In addition to restricting unauthorized users from accessing information, confidentiality also requires to

  implement traffic flow protection measures as part of the security protocol. These protection measures generally include hiding source and destination addresses, frequency of data being sent, and amount of data sent.

  Integrity: Ensures that the information is unaltered . Ensuring integrity requires detection and protection against unauthorized alteration or deletion of information. Ensuring integrity stipulate measures such as error detection and correction for

  both data and systems.

  Availability: This ensures that authorized users have reliable and timely access to systems, data and applications residing on these systems. Availability requires protection against unauthorized deletion of data and denial of service.

  Availability also implies that sufficient resources are available to provide a service.

  Accountability: Refers to accounting for all the events and operations that take place in the data center infrastructure. The accountability service maintains a log of events that can be audited or traced later for the purpose of security.

• Question 307:

  Which NAS backup environment uses a NAS head to retrieve data from storage over a SAN and then sends the data directly to the backup device?

  A. Serverless
  B. NDMP three-way
  C. NDMP two-way
  D. Server-based
  C. NDMP two-way

  NDMP 2-Way

  

  NDMP is an industry-standard TCP/IP-based protocol specifically designed for a backup in a NAS environment. It communicates with several elements in the backup environment (NAS head, backup devices, backup server, and so on) for data transfer and enables vendors to use a common protocol for the backup architecture. Data can be backed up using NDMP regardless of the operating system or platform. Due to its flexibility, it is no longer necessary to transport data through the application server, which reduces the load on the application server and improves the backup speed. NDMP optimizes backup and restore by leveraging the high-speed connection between the backup devices and the NAS head. In NDMP, backup data is sent directly from the NAS head to the backup device, whereas metadata is sent to the backup server.

  Figure on the slide illustrates backup in the NAS environment using NDMP 2 -way. In this model, network traffic is minimized by isolating data movement from the NAS head to the locally attached backup device. Only metadata is transported on the network. The backup device is dedicated to the NAS device, and hence, this method does not support centralized management of all backup devices. EMC E10-001 Student Resource Guide.

• Question 310:

  A. Mixed zoning
  B. Port zoning
  C. Both WWN and port zoning
  D. WWN zoning
  D. WWN zoning

  Types of Zoning

  

  Zoning can be categorized into three types:

  -Port zoning: Uses the physical address of switch ports to define zones. In port zoning, access to node is determined by the physical switch port to which a node is connected. The zone members are the port identifier (switch domain ID and

  port number) to which HBA and its targets (storage devices) are connected. If a node is moved to another switch port in the fabric, port zoning must be modified to allow the node, in its new port, to participate in its original zone. However, if an

  HBA or storage device port fails, an administrator just has to replace the failed device without changing the zoning configuration.

  -WWN zoning: Uses World Wide Names to define zones. The zone members are the unique WWN addresses of the HBA and its targets (storage devices). A major advantage of WWN zoning is its flexibility. WWN zoning allows nodes to be

  moved to another switch port in the fabric and maintain connectivity to its zone partners without having to modify the zone configuration. This is possible because the WWN is static to the node port. -Mixed zoning: Combines the qualities of

  both WWN zoning and port zoning. Using mixed zoning enables a specific node port to be tied to the WWN of another node. Figure in the slide shows the three types of zoning on an FC network. EMC E10-001 Student Resource Guide.
