I – TITLE General activities of Southeast Bank IT department.

II – INTRODUCTION

Internship experience plays a vital role for every student to implement their theoretical knowledge and get a practical knowledge from any organization. This report is prepared as partial requirement of the three­month internship program for the SE students o f UB. Southeast Bank Limited has given me the opportunity to complete internship program. In the report I have mainly given concentrate on “General activities of Southeast Bank IT department.”. Information has taken from bank’s website, Annual report, questionnaire fill up and discussing with the employees. Finally I prepared this report under the supervision of DEBAJYOTI KARMAKER Assistant Professor.

a. Rationale of the Study

With the growing competition among nationalized, foreign and private commercial banks as to how the banks operates it banking operation and how customer service can be made attractive. Commercial or private banks are trying to evaluate their traditional banking service to a better standard, to meet the challenging needs. So they pay attention on better performance and existence. Under the above circumstances, it has become necessary for Southeast Bank Limited, one of the private commercial banks, to focus its attention towards the improvement, who are actually executing the policies undertaken by the top management will have a chance to communicate their feelings and will have the feedback about their dealings from the customer.

b. BACKGROUND

BACKGROUND OF SOUTHEAST BANK LIMITED

Southeast Bank Limited is a second­generation bank that was established in 1995 with a dream and a vision to become a pioneer banking institution of the country and contribute significantly to the growth of the national economy. The Bank’s journey began when it was incorporated as a Public Limited Company on March 12, 1995. The Registrar of joint stock companies and firms issued the certificate of commencement of Business of the Bank on the same date. The Southeast Bank received its Banking License from Bangladesh Bank on March 23, 1995. The Bank’s first Branch was opened by Late M. Saifur Rahman, the then Honorable Finance

6

Minister of the Government of the People’s Republic of Bangladesh as the Chief Guest at the commercial hub of the country at 1, Dilkusha commercial Aroa, Dhaka on May 25, 1995.

In its arduous journey since, Southeast Bank has succeeded in realizing the dreams of those who established it. Today it is one of the country’s leading banks in the private sector contributing significantly to the national economy. The Authorized Capital of the Bank today is Tk.10, 000 million. Its Paid­Up­Capital and Reserve reached Tk. 19,000.08 million as on December 31, 2011. The Bank had 1, 848 staff of whom 152 were Executives, 1, 374 were Officers and 322 were other staff as on December 31, 2011.

The Southeast Bank was established by leading business personalities and eminent industrialists of the country with stakes in various segments of the national economy. They established the Bank with a vision to bring efficient and Professional banking service to the people and the business community of Bangladesh to help the national economy grow. The incumbent chairman of the Bank is Mr. Alamgir Kabir, FCA, a professional Chartered Accountant. The Bank’s Managing Director is Mr. Mahbubul Alam, an eminent banker of the country with 44 years experience in both nationalized and local private sector banks to his credit.

The Bank’s operations are built upon unequivocal emphasis on effective corporate governance. The objective is to create, promote and build long­term company value.

Role of Information Technology

Information technology is working as a principle role in the global economy. IT gives great benefit to have the facility to provide information world­wide great benefit to have the facility to provide information world­wide. It will be the dynamics form of the new era. Today, the IT gives communication and methodical power that organizations need to implement trade and management companies globally with much comfort. Because of the present development of information technology they can synchronize their worldwide network of suppliers, distributors and customers, organizations have developed the global information system that a business can run automatically with the time. IT denotes the communication of hardware and software used depending on the requirement of the enterprise. And this how information technology plays an important role in the present world.

III – ACTIVITIES

In South east bank it department there are different type of working team like Bank Ultimus

team, Network operation team, In­house software team, Procurement & hardware Support

Team.

a. Work­Related : As i discuss before a bank it have different team. I work with Procurement

and hardware team, and get little knowledge about Data Center and Disaster Recovery (DR).

1. Procurement: Procurement is the acquisition of goods, services or works from an outside external source. It is favourable that the goods, services or works are appropriate and that they are procured at the best possible cost to meet the needs of the acquirer in terms of quality and quantity, time, and location.

2. Hardware : Hardware, in the computer world, refers to the physical components that make

up a computer system.There are many different kinds of hardware that can be

installed inside, and connected to the outside, of a computer. In bank it hardware

13

team maintains computer hardware, keep all kind of hardware information,

decided new requirement, change old hardware at right time.

3. Data center : A data center is a facility used to house computer system and associated

components such as telecommunications and storage system. It generally

includes redundant or backup power supplies, redundant data communications

connections, environmental control (e.g. air condition, fire suppression) and

security device. Large data center are industrial scale operations using as much.

Electricity as a small town.

Data center Architecture:

14

Power supply in DC:

Power is a primary resource. Many instances of downtime are the result of power

problem. Power supply should be kept free of interruption or distortion. Servers should

be insulated against potential electrical problems. It is important to provide a separate

power source for the data center.

Diagram 1:

15

Diagram 2:

Diagram 3:

16

Cooling :

Data center heat removal is one of the most essential yet least understood of all critical

IT environment processes. As the latest computing equipment becomes smaller and

uses the same or even more electricity than the equipment it replaced, more heat is

being generated in data centers. Precision cooling and heat rejection equipment is used

to collect and transport this unwanted heat energy to the outside atmosphere.

Automatic fire extinguishing system :

A small fire in data centers can result in catastrophic loss by interrupting vital operations

and damaging high­value equipment. In these situations, it's important that fires be

knocked down quickly ­ before they have a chance to spread ­ and that sensitive

electronics and other equipment not be damaged in the process of putting out the fire.

17

SERVER :

A server is a computer that provides data to other computers. It may serve data to

systems on a local area network (LAN) or a wide area network (WAN) over the Internet.

Many types of servers exist, including web servers, mail servers, and file servers. Each

type runs software specific to the purpose of the server. For example, a Web server may

run Apache HTTP Server or Microsoft IIS, which both provide access to websites over

the Internet. A mail server may run a program like Exim or iMail, which provides SMTP

services for sending and receiving email. A file server might use Samba or the operating

system's built­in file sharing services to share files over a network.

While server software is specific to the type of server, the hardware is not as important.

In fact, a regular desktop computers can be turned into a server by adding the

18

appropriate software. For example, a computer connected to a home network can be

designated as a file server, print server, or both.

While any computer can be configured as a server,

most large businesses use rack­mountable

hardware designed specifically for server

functionality. These systems, often 1U in size, take

up minimal space and often have useful features

such as LED status lights and hot­swappable hard

drive bays. Multiple rack­mountable servers can be

placed in a single rack and often share the same

monitor and input devices. Most servers are

accessed remotely using remote access software,

so input devices are often not even necessary.

While servers can run on different types of computers, it is important that the hardware is

sufficient to support the demands of the server. For instance, a web server that runs lots

of web scripts in real­time should have a fast processor and enough RAM to handle the

"load" without slowing down. A file server should have one or more fast hard drives or

SSDs that can read and write data quickly. Regardless of the type of server, a fast

network connection is critical, since all data flows through that connection.

In Data center a server have some information such as : IP, Row no,Os,Product

code,Setup date, Warranty,Memory,Rack No.

Access control:

Security for the Data Center is the Responsibility of the Data Center Management

Department. The Manager is responsible for the administration for this policy. The

following are the general requirements, policies and practices that govern access to this

sensitive area, for which the Foundation has responsibility. It is important that all staff

and business associates follow these policies and practices. Failure to do so is

considered grounds for personnel action. General Access is given to people who have

free access authority into the Data Center. General Access is granted to the Data Center

Management staff whose job responsibilities require that they have access to the area.

19

Limited Access is granted to a person who does not qualify for General Access but has a

legitimate business reason for unsupervised access to the Data Center.

Departments/projects that have equipment in the Data Center may request access to the

Data Center. The individuals designated by the requesting Department/project will be

granted access once the Data Center Management team head authorizes them.

Disaster Recovery (DR) :

A solid disaster recovery (DR) strategy is crucial to protecting a organization's future in

the event of a natural disaster or other emergency that causes downtime.Potential

Threats to be considered and mitigated against could include:

Natural Threats:Fire, Floods and Flash Floods, Hurricane/Storm, Earthquake.

Man­Made Threats : Terrorism, Explosion, Bio­Hazard, Epidemic/Pandemic,

Theft/Vandalism, Work Stoppage, Riot, Power/HVAC Failure, Communications Failure,

Hardware Failure, Software Failure, Security Incident.

Once we have defined your assets, we need to determine how long we can go without

access to this resource. This is called the “ Recovery window” for each asset.

b. Organization­Wide :

Network operation :

In information technology, a network is a series of points or nodes interconnected by

communication paths. Networks can interconnect with other networks and contain sub

networks.

Type of network

Local Area Network(LAN)

Wide Area Network(WAN)

Metropolitan Area Network(MAN)

Network Topologies and Design Goals

20

A network configuration is also called a network topology. A network topology is the sharp

physical connectivity of the network. The network design has three major goals when

establishing the topology of a network:

Provide maximum possible reliability to assure proper receipt of all traffic alternate

routing.

Route the traffic across the least coast path within the network between the sending and

receiving DTE

Give the end user the best possible response time and throughput.

The second major goal in establishing a topology for the network is to provide the least cost

path between the application processes residing on the Data terminal equipment.

This involves:

Minimizing the actual length of the channel between the components, which usually

entails routing the traffic through the fewest number of intermediate components.

Providing the least expensive channel option for particular application for instance,

transmitting low priority data over a relatively inexpensive dial­up, low speed telephone

line in contrast to transmitting the same data over an expensive high speed satellite

channel.

The common network topologies are:

The Hierarchical Topology(Tree)

21

The Horizontal Topology ( Bus)

The Star Topology

The Ring Topology( HUB )

22

The Mesh Topology

Network Overview:

The network architecture typically consists of tree routing, switching and security element with progressively more specialized equipment moving up the network hierarchy. Today management solutions focus primarily on individual pieces of the infrastructure and don’t provide an application center view that span underlying hardware resource. The operational challenges that customer face in the area is the result of a series of shortcoming in the IT infrastructure they have today, and these shortcomings span from development all the way through the operations.

Router:

A router is a device that forwards data packets along networks. A router is connected to at least two networks, commonly two LANs or WANs or a LAN and its ISP's network. Routers are located at gateways, the places where two or more networks connect.

Routers use headers and forwarding tables to determine the best path for forwarding the packets, and they use protocols such as ICMP to communicate with each other and configure the best route between any two hosts.

Southeast Ban IT department use different kind of router for communication. Those routers are:

Juniper J­6350­JB ( core Router ) Juniper J2350­JH (Branch Router ) Juniper SRX­210

Juniper J­6350­JB ( Core Router ) :

Designed to operate in the backbone or core.

23

High availability configured for zero percentage downtime. The entire service provide link connected to this router with additional module number of

the link can be increased. This device forward traffic to branch, SME center, Bangladesh Bank etc. As it is connected to Firewall so all data will be filtered over there.

Juniper J2350­JH ( Branch Router ) :

Internet service provider link connected in the untrust zone of this device. In trust zone internet firewall in connected. Certain protocols are blocked for security issues. To connect with DC all the service provider link connected to the device. Static and OSPF routing configure toward DC. Trust and Untrust created for security concern.

Switch:

In networks, a device that filters and forwards packets between LAN segments. Switches operate at the data link layer (layer 2) and sometimes the network layer (layer 3) of the OSI Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs.

Southeast bank IT department use different kind of Switch for communication. Those switch are:

Juniper Ex8208­REDUND­AC(Core switch) Juniper EX3200­24T(Branch Switch)

Juniper Ex8208­REDUND_AC:

The entire access switch should be connected with the core switch for accessing servers from inside.

Provision to connect via Ethernet or fiber. 6 power supplied in each core switch ensures high level architecture for redundancy. 10Gbps link can connecting with external module for higher throughput. Data will be forwarding to firewall for deep scanning of any threat.

Juniper EX3200­24T (Branch Switch) :

The entire server will be connected to DMZ switch. User from outside world can access data. User can access data at Gig speed. The entire user on a particular VLAN. Static IP configured on the switch.

24

Firewall:

Firewall is a software or hardware­based network security system that control the incoming and outgoing network traffic by analyzing the data packet and determining whether they should be allowed through or not based on applied rule set.

Southeast bank IT department use different type of Firewall for communication. Those Firewalls are:

Juniper NS­lGS­1000 (core Firewall) Juniper SSG­320M­SH (Branch Firewall) Juniper SSG­350M­SH (DMZ Firewall)

Network Purpose, scope, and Objective:

Southeast bank limited intends to apply technology upgrade and additions several areas with the objective of connections all the branches through wide area network. This WAN connectivity will be used for following activities:

Centralized banking operation Data transfer Internet Service Active Directory Service (ADS) VOIP for internal Communication Scalability for video conferencing

This connectivity must have highly secured system in place and faster data transfer with authorized access from and to applications of Head office and branches.

LAN Connection at SEBL:

SEBL cables are connected with channel cable tray and using of ladders, pipes, insulation and sound protection industry has made patch code which are used everywhere. Switch wire manager and all patch panels are decorated in a network rack for different floor and network operation center (NOC). All communication fiber cables are resolved and media converter converts and installs in managed way in the network rack. The next frame is used for wiring in the data center to connect all servers to switch servers and devices.

Complete the switch design and configuration tab of the detailed design workbook in order to finalize the design and configuration of LAN core, Distribution, and access components.

The VLAN design and configure tab of the derailed design workbook to finalize the design and configuration of the VLANs and layer 2 segmentation.

25

The server design and configuration tab of the detailed design workbook to finalize the design and configure to finalize the design and configuration of servers supporting the DC and branch network.

WAN Connectivity of SEBL:

Link3 Technologies Branch Fiber/Radio/Internet connectivity

Gazi Communication Branch VSAT Connectivity

MetroNet Limited Branch Fiber/Radio Connectivity

Alap Communication Internet Broadband Providers

Square Limited Branch Fiber/Radio connectivity

DhakaCom Limited Branch Fiber/Radio/Internet connectivity

Bangladesh online Limited Internet Broadband providers

Banglaphone Limited Branch Fiber/Radio connectivity

26

BDCOM Limited Branch Fiber/Radio connectivity

Schematic Diagram of WAN

SEBL follow a schematic diagram in their data center. There are main three division of whole Data center of Main Branch they are, disaster recovery, Demilitarized Zone (DMZ), and Data center core zone. Now I want to show the schematic diagram of WAN.

27

Demilitarized Zone (DMZ) :

Demilitarized zone is a computer host or small network which act as neutral zone between SEBL private network and the outside the public network. It avoids outside users from getting direct access to a server that has company data. A DMZ is an optional and more

28

secure approach to a firewall and effectively acts as a proxy server as well. DMZ has own router, Firewall, switch and also mail server, Internet banking server and substitute server.

Subnetting Examples in Branches

Here I get opportunity to take knowledge SEBL branches subnetting Class C addresses using

the method i want to described about it.

Suppose, The main IP address is 192.16.0.0 . The main IP address devided to 3 branches.

Dilkusha branch are connected to 64 PC’s here our subnetting 192.16.0.0 to 192.16.0.63 and

29

there CIDR value 26 , block size 64. Where is subnet mask 255.255.255.192. Mirpur branch are

connected to 08 PC’s Where is subnet mask 255.255.255.248. Aganagar branch are connected

to 16 PC’s, here our subnetting normally start 192.16.0.72 but Aganagar branch start

192.16.0.80 because Mirpur branch reserved some IP address. So our useable IP address are

192.16.0.. to 192.16.0.79. For that reason Aganagar branch subnetting are 192.16.0.80 to

192.16.0.95 and there CIDR value 28, block size 16. Where is subnet mask 255.255.255.240

IV – CONSTRAINTS

It is not very easy to achieve the maximum result from any project. Lots of limitation and

constraints make the whole thing though to reach to its ultimate destination. I faced some

limitations to accomplish this report.

Those limitations are

For time constraints the duration of the study was very short to know all the

general activity of the IT department.

Collection of information was difficult due to the policy about the secrecy of the

bank.

Bank It is a very busy department. Therefore it was tough to give me time.

Not enough information found from the Annual report regarding my topic.

Academic knowledge is not enough for job sectors. Academy teaches us initial

level of knowledge but job sectors is vast area where we have to gather more

31

and more knowledge about our own sectors. But academic knowledge works

properly when we drop our CV in various Companies then it works like written

exam, viva etc. Academic knowledge increases our confidence to challenge or

face the threats of job organization.

V – ACQUIRED KNOWLEDGE

Internship has been very much fruitful for me as i have gained a lot of experience on how to

work in an official and professional environment. This is my first experience in a banking area,

so these 3 months of internship program give me a different experience.It has give me the

chance to develop my skill and Data center management, Hardware management of a large

organization.

a. Implications to Organization/Company

Hardware : In information technology, hardware is the physical aspect of computers,

telecommunications, and other devices.

Network Printer : A printer connected to a wired or wireless network. It may be Ethernet

enabled and be cabled to an Ethernet switch, or it may connect to a Wi­Fi (wireless)

network, or both. See print server, Ethernet, Wi­Fi and production printer.

ON­LINE UPS : The definition of an ON­LINE UPS system is one where the Inverter is

supplying 100% of the load 100% of the time. It is always completely regenerating the

output waveform internally within the UPS. There is no transfer switch to be activated

upon loss of AC or when a brownout condition occurs. If the back­up power system does

32

not match these criteria, it is not an ON­LINE UPS.

Data center : A data center is a facility used to house computer system and associated

components such as telecommunications and storage system. It generally includes

redundant or backup power supplies, redundant data communications connections,

environmental control (e.g. air condition, fire suppression) and security device. Large

data center are industrial scale operations using as much. Electricity as a small town. I

also gather a small knowledge on data center management which is a big part of my

intern time. In data center management means :

Performance Management.

Network performance management.

Power performance management.

Cooling performance management.

Auto fire extinguisher.

IP Management.

Hardware Management.( Server, PDU,UPS)

Access control

Rack Management. ( IP, Row no,Os,Product code, Setup date, Warranty,

Memory)

b. Implications to University’s Internship Program

District intern programs are similar to traditional American International university­Bangladesh

(AIUB) internships in that the intern is both a full time teacher and full time student. In a

33

university intern program, interns are employed by the district and are enrolled full time in the

university’s teacher preparation/education program. In a district intern program, the district

employs the intern and delivers the teacher preparation program. The IMPACT Intern Program

applies the concept of the district internship to a county­wide consortium model with the county

office providing coordinated development and geographically convenient delivery of a

comprehensive teacher training program to interns throughout the county. Upon completion of

the program, interns are eligible for a professional teaching credential. Funding to operate the

IMPACT Intern Program is from three sources: grant funds, intern fees and district in­kind

support.

VI – CONCLUDING STATEMENTS

a. Recapitulation /Summary

The main purpose of the report is to provide a basic idea of Southeast Bank Limited IT

department, and how Southeast Bank Limited IT Performed. The report will also present

the various terms and conditions of maintaining the different services of Southeast Bank

Limited. Generally by the word ‘Bank’ we can easily understand that the financial

institution deals with money. The Activity of IT in a bank:

Bank has always been a highly information activity that relies heavily on information

technology to acquire process and deliver the information to all relevant users. Not only

is IT critical in the processing of information, it provides a way for the bank to

differentiate their products and services. Bank find that they have to constantly innovate

and update to retain their demanding and discerning customers and to provide

convenient, reliable and expedient services. Driven by the challenge to expand and

capture a large share of the banking market, some banks invest in more bricks and

mortar to enlarge their geographical and market coverage. Other have considered a

more revolutionary approach to deliver their banking service via a new medium: “The

Internet”.

Finally I would like to conclude by praising the entire internship program, through which i

have been able to achieve some significant experience and knowledge, as one of the

most crucial segment of my academic career which is certainly valuable for the

development of my future professional and academic career as well.
