Network Design

Following a structured set of steps when developing and implementing network, security will help to address the varied concerns that play a part in security design. Many security strategies have been developed in a haphazard way and have failed to actually secure assets and to meet a customer’s primary goals for security. Breaking down the process of security design into the following steps will help effectively plan and execute a security strategy:

  1. a) Identify network assets.
  2. b) Analyze security risks.
  3. c) Analyze security requirements and tradeoffs.
  4. d) Design a security plan.
  5. e) Define a security policy.
  6. f) Develop procedures for applying security policies.
  7. g) Develop a technical implementation strategy.
  8. h) Achieve buy-in from users, managers, and technical staff.
  9. i) Train users, managers, and technical staff.
  10. j) Implement the technical strategy and security plan.
  11. k) Test the security and update if any problems are found.
  12. l) Maintain security.

Modularizing Security Design

Security experts promote the security defense in depth principle. This principle states that network security should be multilayered, with many different techniques used to protect the network and each mechanism should have a backup mechanism. This is sometimes called the beltand-suspenders approach. Both a belt and suspenders ensure that trousers stay up. A networking example is to use a dedicated firewall to limit access to resources and a packetfiltering router that adds another line of defense.

In general, using a modular approach to security design is a good way to gain an understanding of the types of solutions that must be selected to implement security defense in depth. The next few sections cover security for the following modules or components of an enterprise network:

  1. a) Internet connections
  2. b) Remote-access and virtual private networks (VPN)
  3. c) Network services and management
  4. d) Server farms
  5. e) User services
  6. f) Wireless networks

For which a Data Center, a Disaster Recovery Site, Dual Network connectivity and operating policy has been prepared which are currently in operation. To support the users 24 hour support center called NOC (Network Operation Center) is in live. The officers perform their duty in shift, management of which is under Data Center team. Data Center Team circulates roster duty schedule as prepared by them and approved by Head of IT at the end of each month for the next month.

Operating Policy:

Maker checker request received by IT through proper channel. Initiated by user and approved by Branch Manager. Users are created by Valid admin user of IT Division. Certain limit is requested by the branch for execution of branch operation.

User permission is sanctioned as per request processed from branch. Operating time is open as there is no time restriction has yet been instructed by competent authority. The operating time schedule will be implemented as and when instructed by authority.

Operation Calendar for the year is set before start of the year. Other holidays are set as and when required.

Recommendation and Future Planning Policy

Cloud Computing


Cloud Computing is a recent revolution in the world of Information Technologies that enables a convenient way to share resources. It is model providing on-demand network access to configurable IT devices and services (e.g. Servers, Storage, and Applications) gathered as a network of computing resources located anywhere, being shared among its users. Cloud Computing can provide greater flexibility and improved levels of service, while making costs more transparent and increasing institutional efficiency. It is anticipated that the use of Cloud Computing services will grow significantly over the next generation.

This policy is intended to ensure that the use of these services is managed in accordance with existing IT requirements, and to provide a level of Head of IT oversight to address the possibility of a higher level of risk existing because of these new and still-evolving IT service models. The primary reason for this policy is to facilitate a well-managed and successful adoption of Cloud Computing by establishing a process that directs attention to IT related requirements, management processes, and risk factors.


Cloud Computing is a computing model in which technology resources are delivered over the network. Rather than implementing and maintaining, IT services locally, customers of cloud computing buy IT capabilities from providers that manage the hardware and software that operate those services. Resources including infrastructure, software, processing power, and storage are available from the cloud. However, migrated cloud platforms and services cost benefits as well as performances are neither clear nor summarized. Globalization and the recessionary economic times have not only raised the bar of a better IT delivery models but also have given access to technology-enabled services via internet.

However, in spite of the cost benefits, many IT professional believe that the latest model i.e. “Cloud Computing” has risks and security concerns. The following factors should be considered during cloud computing:

  1. a) Idea behind cloud computing.
  2. b) Monetary cost benefits of using cloud with respect to traditional premise computing.
  3. c) Security issues of cloud computing.

We have tried to find out the cost benefit by comparing the Microsoft Azure cloud cost with the prevalent premise cost.


Use of Cloud Computing services must be formally authorized in accordance with the IT Division.

Use of Cloud Computing services must comply with all current laws, IT security, management policies, and risk.

Use of Cloud Computing services must comply with all privacy laws and regulations, and appropriate language.

Cloud Computing services will not be avail without any writing approval of IT Division. The Head of IT division will certify that security, privacy, and other IT management requirements that adequately addressed prior to approving use of Cloud Computing services.

The Cloud Computing service may not be put into production use until IT Division has provided written approval.
