History of ICT Division
The ICT division started its journey since 1998.
At first stage its name was MIS Dept.
Name changed into MIS & ICT Division when it was fully computerized and create network to the branch offices for faster communication
From 2009, ICT Division took all responsibility regarding IT.

Uttara Bank ICT division Operation overview
There are four department under ICT division, they are-
1. MIS Dept.
2. Development & Support Dept.
3. Card Dept.
4. CBS(Core Banking Solution) Dept.

Responsibility of Development and Support Dept.
The performance of development and support department can be categorized in three sub departments; such are:
1.Support department: provides online or phone call based support.
2.Software support: Develop bank’s own use software update it as needed..
3.Hardware support: provide hardware related support

Network Planning & Designing of Uttara Bank
Network planning and designing is a complex process that involves topological network design, network-synthesis, network-realization etc. for a proposed communication network of an organization. Network planning and designing should satisfy the following requirements—
Identifying Usable Application
Traffic Requirements
Geographical considerations
Security & Accessibility
Cost Considerations

Equipments used in existing network
1. Juniper SRX-210 Router- This Router is being used as Core router and Branch level router. Some hardware limitation is there
2. D-Link DGS-1024D Switch- This is an unmanaged switch. Have no controls over its performance

Equipments used in existing network
3. IBM System x3500 M3 Server- high-performance dual-socket tower server provides generous bandwidth, storage and expanded memory
capacity up to 192 GB. Start with a single Intel Xeon six-core processor. Up to two six-core Intel Xeon X5690 3.46 GHz processors or four-
core Intel Xeon X5687 3.60 GHz processors.

Equipments used in existing network
4. IBM System x3500 M4 Server – Deliver the scalability, reliable performance and optimized
efficiency for real business critical applications. Up to two Intel Xeon Processor E5-2600 product family Up to 1600 MHz memory speed.
11
Disadvantages of the existing network During my internship activities I found some problem in the existing network .They are-
WANs are vulnerable to hackers and viruses.
Lack of Security measures to restrict access to the network.
Bandwidth is less
During over-traffic of data the performance degrades as the network is not designed properly.
12
Online Banking Services Here are some of the other advantages that banking online offers:
24/7 service
Acquiring monthly statement
Cost Effective
Paperless
Geographical Convenience
Pay various type of bills

Equipments for the new network
Blade Center H – IBM Blade Center H Server includes 14 blade slots . Advanced Management Modules. Fiber channel InfiniBand or Myrinet 2000 functions. It runs on Linux Enterprise
21
IBM Servers
Equipments for the new network
System i5 570 eServer – 16-way POWER5 processor, 2GB – 512GB memory B Runs on i5/OS V5R4, and can also support AIX, Linux, Lotus
Domino, Windows 2000 and Windows Server 2003.
22
Advantages of the new network
Hardware level security is there
Unlimited Bandwidth
Availability of Collaborative Software.
Availability of File Server
Banks create a new revenue stream through Mobile Banking.
23
Disadvantages of this network
With my Study regarding Implementation of Secured Networking ,I found some draw backs. They are-
Security encryption is not that strong
Weak Bandwidth Management

My Idea Regarding New Network plan of Data Center WAN Active Device for UBL –Modified Schematic Diagram
25
What is DMZ?
A DMZ is a "demilitarized zone." In networking, a DMZ enforces the firewall that stands between a private Local Area Network and the Internet. This configuration is usually used when a company has a website that it wants the outside world to access, but does not want outsiders to access its private network.
26
Increasing Efficiency
In order to make the new network plan a much more efficient for mobile and internet banking I come up with some additional plans.
The additional things that I have added are-
1. Mobile Sim Box
2. Federation Service Server
3. Certificate Authorization Server
4. Redundant connectivity by providing Auxiliary Cloud.
27
Mobile Banking
28
1.Mobile Sim Box
Some important feature of Mobile Sim box are-
Can insert 32 SIM cards(big or small)
Connection with the computer through a data line can be integrated with USB
Each channel with separate power switch
Each individual module can be demolished

2.Federation Server
A feature that enables organizations to communicate easily and securely across the public Internet.
As long as both organizations have deployed an Access Edge server, federation can be used to view presence and exchange IMs.
Organizations can also use federation to participate in web conferences.
31
How Federation Server Works

3. Certificate Authority Server
Certificate servers validate, or certify, keys as part of a public key infrastructure.
The purpose of this process is to create a way for people to communicate safely.
This allows others (relying parties) to rely upon signatures or assertions made by the private key that corresponds to the public key that is certified.
In this model of trust relationships, a CA is a trusted third party that is trusted by both the subject (owner) of the certificate and the party relying upon the certificate. CAs are characteristic of many public key infrastructure (PKI) schemes.

How Cloud Computing Works

4. Redundant Connectivity through Auxiliary Cloud
Some features of Auxiliary Cloud:
Data is transferred through secured channels using HTTPS protocol.
Data encryption feature.
The deduplication feature enables you to use the network bandwidth efficiently.
Efficient use of data store due to Data Deduplication.
37
ConclusionBefore introducing Mobile and Internet Banking Uttara Bank should
imply more security measures like adding Federation Server, Certificate Authority Server.
For efficient and faster push and pull messaging service they should add the Mobile Sim box
It’s high time to add Auxiliary Cloud to their Network.
This Internship helped me a lot to learn many things, which would be helpful in my future career.
