 Risks caused by poor security knowledge and practice:
 Identity Theft
 Monetary Theft
 Legal Ramifications (for yourself and your organization)
 Sanctions or termination if policies are not followed
Cyber Security
• The internet allows an attacker to work from anywhere on the planet.
• Cyber Security is the safeguarding of computer systems and networks against data leakage, theft, or
damage to their hardware, software, or electronic data, as well as disruption or misdirection of
services.
Why is Cyber Awareness Important?
• Cyber crime is a growing trend with advancement of technology
• Raise awareness of threats
• As with most crimes the police can’t tackle this problem alone
• To encourage reporting of Cyber Crime to enforcement agencies
• Cyber crime is massively under reported.
• Identity Theft
• Monetary Theft
• Legal Ramifications (for yourself and your organization)
• Departmental Action or termination as per the policies
Risks caused by poor security knowledge and practice

Causes for Concern
University of North Dakota:
https://onlinedegrees.und.edu/blog/types-of-cyber-attacks/
Since 2014, security breaches have
increased by 67%.
25% of breaches in 2019 were motivated
by espionage.
4.1 billion records were exposed by data
breaches in the first half of 2019.
On average, hackers attack every 39
seconds, 2,244 times a day.
68% of business leaders believe their
cyber security risks are increasing.
71% of breaches in 2019 were financially
motivated.

Common Causes of Cyber attacks
• Weak or stolen usernames and passwords
• Application vulnerabilities
• Absence of Antivirus and latest patches
• Use of Pirated Operating Systems
• System and Network Firewalls disabled
• Social engineering (tricking people into breaking security protocols)
• Poor access control (Unauthorized users have access)
• Insider threats (System Password has not set)
• Improper configuration of WIFI devices and Hotspots
• Unnecessary Ports opened on Network for Backdoor Entry

Malware

Malware is intrusive software that is designed to damage and destroy application and computer
systems. Malware is a contraction for “malicious software.” Examples of common malware includes
viruses, worms, Trojan viruses, spyware, adware, and ransomware.
Salient Differences
1) Computer Virus:
• Needs a host file
• Copies itself
• Executable
2) Network Worm:
• No host (self-contained)
• Copies itself
• Executable
3) Trojan Horse:
• No host (self-contained)
• Does not copy itself
• Imposter Program

• Phishing: a ‘trustworthy entity’ asks via e-mail for sensitive information such as UID, credit card numbers, login IDs
or
passwords. It is a kind of social engineering attack where a person steals the sensitive information of user in a fraud
manner by disguising as a legitimate person.
• Spoofing is a kind of computer virus attack where a person steals the details of important a legitimate user and acts
as
another user. It is a kind of identity theft. Cyber criminals use spoofing to fool victims into giving up sensitive
information or money or downloading malware
• Ransomware is a new type of malware that encrypts documents, pictures and other files, making them unreadable.
The
attacker then holds the decryption key for ransom until you agree to pay money, usually through an untraceable
method
such as BitCoin or other digital currency.
Do:
• Always verify the sender of a message.
• Always hover over web page links (URLs) in email messages to see where they link to – beware URL
shortening services (like bit.ly) that may obscure the final web site destination.
• Be skeptical of messages with odd spelling/grammar, improper logos or that ask you to upgrade or verify
your account.
• Report suspicious emails to support@gov.in or NIC
• Take backups of important files to avoid ransomware
Don’t:
• Open an attachment from an unknown sender. Consider the source and whether or not the file was
expected.
• Click on a link from an unknown sender.

Social engineering manipulates people into performing actions or divulging confidential information. Similar
to a confidence trick or simple fraud, the term applies to the use of deception to gain information, commit
fraud, or access computer systems.
Phone Call:
This is John,
the System
Admin. What
is your
password?
Email:
ABC Bank has
noticed a
problem with
your account…
In Person:
What ethnicity
are you? Your
mother’s
maiden name?
and have

software
patches
I have come
to repair
your

Violation of Information Security
International Threat
Information Tampering
Information shall be harvested by private companies owning
the platform as they control storage servers that are often
located outside the country.
Disrupt digital operations or damage information of the
plans and projects yet to be formalized
The classified official communication(i.e. in four categories TOP SECRET, SECRET, CONFIDENTIAL and RESTRICTED. ) on
public domain messaging platform like WhatsApp, Telegram, messenger etc. is a clear violation of information security
instructions as provided in Manual of Departmental Security Instructions (MoDSl) and National information Security Policy
Guidelines (NISPG).
According to NISPG, the Top Secret and Secret information shall be shared only in a closed network with leased line
connectivity where Scientific Analysis Group - DRDO(SAG) grade encryption mechanism is deployed. However,
Confidential and Restricted information can be shared on internet through networks that have deployed commercial AES
256-bit encryption.
Individual Information leakage
Personal information of an individual is used for adversaries
or can be monetised for gains.

1) Use eOffice for official communication: The product is developed by
National Informatics Centre (NIC) and aims to usher in more efficient,
effective and transparent inter-government and intra-government
transactions and processes. it may be advised that the
Ministry/Department may deploy proper firewalls and white-listing of
lP addresses. The eOffice service may be accessed through a Virtual
Private Network (VPN) for enhanced security. The Top Secret & Secret
information shall be shared over the e-Office system only with leased
line closed network and SAG grade encryption mechanism.
Benefits of eOffice :
• Enhance transparency
• Increase accountability
• Assure data security and data integrity
• Promote innovation by releasing staff energy and time from
unproductive procedures
• Transform the government work culture and ethics
MHA Recommendations to maintain Cyber Security

2) Use Government Email (NIC Email) for official communication: NlC email
facility or Government instant Messaging Platforms (such as CDAC's Samvad,
NIC's Sandesh, etc.) is recommended in the Ministry/Departments for the
communication of Confidential and Restricted information. However, utmost
care should be taken during the classification of information and before the
communication of the same over internet (i.e. an information which may
deserve a Top Secret & Secret classification shall not be downgraded to
Confidential/Restricted for the purpose of sharing the information over the
internet).
• Features…
• Email platform is supported by 2-level authentication factor i.e. KAVACH
which enables extra security.
• The feature of BRIEFCASE which is used to store the personalize
data similar to google drive
• NIC never asks…
•… for your credentials via email or over the phone.
•… to follow a link to clean a virus from your email mailbox, upgrade or
reactivate your account.
•… you to update or increase your email quota.
When in doubt, forward suspicious emails to support@gov.in or NIC Division of
Ministry
MHA Recommendations to maintain Cyber Security(Cont.)

3) Use only Government Video Conferencing solutions: The VC
platforms offered by CDAC, CDOT and NIC (BharatVC, VidyoConnect,
Studio based) may be used. The meeting lD and password shall be
shared only with authorized participants. To ensure better security,
the 'Waiting Room' facility and prior registration of the participants
may be used. However, Top Secret and Secret information shall not be
shared during the VC.
Benefits of Government VC solutions :
• Due to secure network transmission which assures data security
and data integrity
• Data recordings and sharing rights are confined within
government organizations like CDAC, CDOT and NIC.
• It prohibits the trespassers from breaching into the system as
communication happens within dedicated government network
and servers.

4) Avoid Digital Assistant devices: While discussing official information
avoid usage of digital assistant devices like Amazon's Echo, Apple's
HomePod, Google Home, etc. and may not be kept in office. Further,
Digital Assistants (such as Alexa, Siri, etc.) should be turned off in the
smart phones/watches used by the employee. Smart phones may be
deposited outside the meeting room during discussion on classified
issues.
Benefits of avoiding digital assistant devices:
• Decrease the chances of incident that results in unauthorized
access to information.
• Increase accountability

The Open Web Application Security Project (OWASP) Top 10 is a standard
awareness document for developers and web application security. It represents
a broad consensus about the most critical security risks to web applications.
OWASP Top 10 / Server Hardening / Incident Reporting
Server hardening is a set of disciplines and techniques which improve the
security of an server. Hardening is the changes made in configuration, access
control, network settings and server environment, including applications, in
order to improve the server security and overall security of an organization’s
IT infrastructure.
➢ CERT-In is functional organization under MEitY with the objective of securing India cyber space and respond to cyber attacks.
➢ incident@cert-in.org.in is the email address to report any incident of cyber attack.
➢ For closing of Fake / clone websites and applications FIR copy is mandatory for necessary actions.

• Keep your device software up to date – unpatched software leaves your device vulnerable to attack. Install
operating system updates as well as updates to applications.
• Have anti-virus and/or anti-malware software installed, enabled and set to automatically update.
• Never leave your laptop or mobile device unattended. Thefts do happen.
• Encrypt laptops and external media that contains restricted or sensitive data.
• Make sure you backup your data frequently in case your device is ever lost or stolen.
• Ensure access to your mobile device is protected with a passcode and use built-in encryption settings to ensure
that your data is safe if your device is ever lost or stolen.
• Consider using a remote tracking/wipe function if supported. For iOS devices, iCloud provides the “Find my
iPhone” service for free. Android and other mobile operating systems also have similar functionality.
Mobile Device Security

Password Protection
S.No. Dos Don’ts
1. Use hard-to-guess passwords or passphrases. A
password should have a minimum of 10 characters using
uppercase letters, lowercase letters, numbers, and
special characters.
To make it easy for you to remember but hard for an
attacker to guess, create an acronym. For example, pick a
phrase that is meaningful to you, such as “My son's
birthday is 12 December 2004.” Using that phrase as your
guide, you might use Msbi12@Dec,4 for your password.
Do not use simple dictionary words, your name,
username, Date of Birth, Vehicle No, Relatives, Pet
names, computer terms (Admin etc.), common names
(including people or city etc.), technical jargon, etc. as
password.
Do not use all letters or all numbers, repeating
sequences and keyboard sequences, word, or number
patterns (abcdefg, qazxsw, qwerty, 123456 etc).
2. Use different passwords for different accounts. If one
password gets hacked, your other accounts are not
compromised.
Do not share passwords or other Sesnitive Information
with others or write them down on Notepads or Sticky
Note etc.
3. Keep your passwords or passphrases confidential. You
are responsible for all activities associated with your
credentials.
Do not respond to phone calls or emails requesting
confidential data.
4. Change passwords on a regular basis. It helps to prevent
your passwords from being compromised.
Do not use auto save for PASSWORD and other
sensitive information.
Cyber Security - Dos and Don’ts

System Protection
S.No. Dos Don’ts
1. Install the NIC managed centralized antivirus for regular
updates and to check malicious traffic.
Do not install and update antivirus from unauthorized
sources or click on unauthorized links prompting to install
antivirus or any other softwares.
2. Enable system Antivirus, firewall and install OS patches /
upgrades time to time on machines (Desktop, Laptop, mobile
etc.).
Do not use EoL (End of Life) and pirated Operating System,
Office Utility or any other prirated softwares. Use only
genuine softwares.
3. Always Install the softwares only receommeded by IT
Department. Also, remove / delete the unnecessary softwares,
folders and files from your Workstations on timely manner.
Do not install unauthorized programs on your work
computer. Malicious applications often pose as legitimate
software. Contact your IT support staff to verify if an
application may be installed.
4. Routinely and periodically update systems and applications
for all devices.
Do not use outdated devices or unsupported software
versions which increase the risk of information’s being
compromised.
5. If you are going short break, always lock your Laptop/PC.
Never keep Laptop or PC unprotected.
If you are going for Longer Duration Meeting etc, try to keep
the Laptop on Sleep Mode to save Energy.
Do not leave laptop or other devices accessible and
unattended at any time which could allow for unauthorized
access.
Do not leave laptop and other devices in a non-trusted
environment which presents a higher risk of the device
being stolen or compromised.

Information dissemination and disposal
S.No. Dos Don’ts
1. Use of Gov.in / NIC.in emails for official communications. Do not use personal email ids except those exempted.
2. Use privacy settings on social media sites to restrict access to
your personal information.
Do not post any private or sensitive information, such as
credit card numbers, passwords, or other private
information, on public sites, including social media sites,
and Do not send it through email unless authorized to do so.
3. Destroy information properly when it is no longer needed from
electronic media and papers. Recycle bin should be cleaned
daily.
Do not retain Information for longer than necessary.
4. Regulate the use of USB storage devices like pen drive, smart
phones, tabs etc. It has been observed that unregulated use of
many such devices is one of the reasons for spread of
malware in the network.
Do not create HOTSPOT on machines to avoid misuse
5. Hard Disk should be formatted before moving Computer from
different sections and responsibilities to avoid data leakage
Do not use MTNL/ AIRTEL/ VODAFONE/ JIO etc. ISP
networks on official machines.

Phishing or Smishing or Vishing Attacks
S.No. Dos Don’ts
1. Pay attention to phishing traps in email and watch for
telltale signs of a scam. Always think before you click to
help keep yourself and organization safe. The common
actions that a malicious sender will try to get you to take
are:
i. Opening an attachment deemed to be highly
important or urgent
ii. Reply immediately (including clicking an unsubscribe
option)
iii. Clicking any hyperlinks in the message (including an
unsubscribe option)
iv. Forwarding the email message to others
Do not open mail, attachments, links (received on email,
SMS and popup notifications etc.) from an unknown or
untrusted source. Cyber attackers often use them to
trick you into visiting malicious sites and downloading
malware that can be used to steal data and damage
computers/ networks.
If you receive a suspicious email, the best thing to do is
to delete the message and report it to NIC/ Information
Security Officer (ISO)/designated security
representative.
2. Use caution if you receive an email that includes
attachments or links that ask you to act. Always ensure
the sender is trusted, purpose of link, URL associated
with link etc.
Do not be tricked into giving away confidential
information. It’s easy for an unauthorized person to call
and pretend to be an employee or business partner.

Physical information Protection
S.No. Dos Don’ts
1. Ensure that all the material shorthand notebook etc. used
to prepare the final draft are treated the same way as the
final draft. The unused or previously used documents
should be trashed or destroyed.
Do not leave unused drafts or sensitive information
lying around the office.
2. Be aware of your surroundings when printing, copying,
faxing, or discussing sensitive information. Pick up
information from printers, copiers, or faxes in a timely
manner.
Do not leave printouts or portable media like pen drive /
CD/ DVD containing private information on your desk.
Lock them in a drawer to reduce the risk of
unauthorized disclosure.
