CHAPTER 1
INTRODUCTION
At the end of December 2015,a group of undergraduate students were selected to perform
internship at Robi Axiata Limited from 7th
January 2016.Students were selected to different
projects by the project advisor, based on their qualities for the work.The projects were supervised
by the respective line manager. I was selected as an Intern at Technology Division user the
supervision of Kranti Mahbub, General Manager,OSS & IT Operations,Technology Division,
Robi Axiata Ltd. This report provides a short summary of “Malware Cleanup Project” with other
addition work. This report is prepared on the basis of my three-month practical experience at
Robi Axiata Limited. This internship program helped me to learn about the practical scenario of
a Telecommunication Company.
1.1 Why Internship
As a University student I have only the theory based knowledge. But practical or real world is
much different from the theory based world. As I have no practical knowledge I do prefer to
have hand on experience. Internships are key to building experience as a student or recent
graduate. Employers are much more likely to hire someone with internships and work experience
rather than someone with a generic resume, lacking experience. Joining a company as an intern
gives you the opportunity to work hands on in a professional environment. Internships help by
teaching you more about the career path you are pursuing. Internships are a way to test drive
possible jobs and explore different career options. Moreover team management is on the best
need of real world. To cope up with the real world one should manage a good team management
skills. So for this skill one should join for an internship after university life. Finally to maintain a
good time management skill one should take internship after graduation.
1.2 Why Robi
Robi Axiata Limited is one of the most leading mobile operator in Bangladesh. Robi focuses on
developing & sharpening the technical skills of fresh graduates of our country. They encourages
the fresh graduates to develop their skills, their interest. From my student life I found many
programs where Robi sponsored to run the program. So I preferred Robi for my internship.

CHAPTER 2
ACTIVITIES UNDERTAKEN
2.1 Malware Cleanup Project
Malware is a set of instructions that run on a computer and make the system do something that
an attacker wants it to do. Malware steals personal information, delete files, spread spam and
tracks user’s activity. My job tasks in this project are to identify the threat workstation form the
threat database. Checking whether the Antivirus signature (DLP, Data Loss Prevention) is
updated or not. If not then update the signature. Sometime manual update is not possible than
setup/configure the software with proper admin permission and steps. Scanning the threat
workstation remotely and checking the On Demand Scan Log whether malware is still present or
not. If still present then upload the Getsusp log to system server and then contact with the
security team for further process.
2.1.1 Limitations
I have to face some limitations of workstation access .Such as user’s unavailability, LAN
connection problem etc. Most of the users were in remote area so due to LAN connection
problems I could not access to end user workstation. Sometimes users were not free of my time
so I have to take time from them and completed my work on their free time.
2.1.2 Recommendations
The battle for IT security will never end, but the application of best practice and the effective
sharing of available knowledge. We recommend that as a business you take steps to review, and
invest where necessary, to improve security in the following key areas:
 User Education & Awareness
Establish a Staff training program for increasing user awareness of the malware risks.

9. Page 3 of 11
 Managing user privileges
Establish account management processes and limit the number of privileged accounts. Limit user
privileges and monitor user activity.
 Removable Media Controls
Removable media access control is already maintaining by the DLP end user policy. System
team need to make another policy like, if the user doesn’t scan the removable media then the user
can’t access to it.
 Regular Monitoring
System team should regularly monitor strategy & produce supporting policies. Continuously
monitor all ICT systems & networks. Analyze logs for unusual activity that could indicate an
attack.

CHAPTER 3
ADDITIONAL WORKS
In addition to the Malware cleanup project I have to perform other works also. Such as
3.1 Mail Archiving Project
Exchange Online Archiving is an additional specialized mailbox that works in tandem with users
Primary Exchange Mailbox allowing messages to be quickly and easily archived to simplify
mailbox size management.This solution utilizes server-side storage that works in a similar
manner to the traditional Personal Folders (PST) files. This approach has the advantage of being
backed-up nightly, can have messages moved into it automatically,and is available within
Webmail (http://mail.robi.com.bd/owa) providing access on and off Office. Users email will be
auto archived to Microsoft cloud storage. Users need not to archive email on their own Laptop
HDD. Emails older than 15 Days will be auto archived to Microsoft cloud storage. Archived
emails will be accessible from both outlook & webmail. i.e. you can access your archived email
from outside office network.
The task of this project is to default the ost from pst. This time I got excel file where a list of
people name where available whose outlook was default to PST(personal archive folder).For this
work first I contact with the user, informed him/her about the issue, note down the user's
available time and on that time I changed the archive folder to exchange remotely with the
permission of the user.
3.2 Bit locker refresh/password reset
The life time of bit locker is 5 times. When user put 5 times wrong password than the blocker
account gets locked. Sometimes bit locker doesn't take password if a cd in the cd rom or caps
lock on/off. In this time the support cannot be provided remotely so we have to request the user
to send the laptop to us(IT Help Desk).This time I have to send the Computer Name and the
previous recovery key to the team member who have the admin access of generating recovery
key for bit locker.
When a user already put2/3 times wrong password but successfully logged in than we can
remotely refresh the bit locker from the control panel if the user call logged to IT Support. It
helps the user for getting 5 times lifetime again.

3.3 Remove stored passwords, certificates, and other credentials
Credential Manager allows you to store credentials, such as user names and passwords that you
use to log on to websites or other computers on a network. By storing your credentials, Windows
can automatically log you on to websites or other computers. Credentials are saved in special
folders on your computer called vaults. Windows and programs (such as web browsers) can
securely give the credentials in the vaults to other computers and websites.
If you no longer need credentials stored on your computer that you use to log on to websites or
other computers on a network, follow the steps below to delete them. For more information
about stored credentials, see Store passwords, certificates, and other credentials for automatic
logon.
3.4 Workstation setup/configuration
Full setup of workstation with Acronis or R-drive image software. After installation I have to set up the
domain (robi.com.bd) with the PC name with End user Employee ID. Finally I have to encrypt the
workstation with bit locker drive encryption software.
3.5 An attendee to Robi Airtel Merger Program
I got the permission for attending the Robi Airtel Merger Program which was held at BTRC office, Dhaka.

According to my own experience working with Robi is a memorable part of my life. Robi’s
working environment is very nice and friendly specially the OSS & IT Operations team who
always on work pressure but never forget to share their joyful moments to each other. The senior
