1.2 Cybersecurity Criminals
versus Cybersecurity
Specialists

Presentation_ID 18
Cybersecurity Criminals vs Cybersecurity Specialists
Cybersecurity Criminals
▪ Hackers – This group of criminals breaks into
computers or networks to gain access for various
reasons.
White hat attackers break into networks or computer
systems to discover weaknesses in order to improve
the security of these systems.
Gray hat attackers are somewhere between white and
black hat attackers. The gray hat attackers may find
a vulnerability and report it to the owners of the
system if that action coincides with their agenda.
Black hat attackers are unethical criminals who
violate computer and network security for personal
gain, or for malicious reasons, such as attacking
networks.

Presentation_ID 19
Cybersecurity Criminals versus Cybersecurity Specialists
Cybersecurity Criminals (Cont.)
Criminals come in many different forms. Each have their own motives:
▪ Script Kiddies - Teenagers or hobbyists mostly limited to pranks
and vandalism, have little or no skill, often using existing tools or
instructions found on the Internet to launch attacks.
▪ Vulnerability Brokers - Grey hat hackers who attempt to discover
exploits and report them to vendors, sometimes for prizes or
rewards.
▪ Hacktivists - Grey hat hackers who rally and protest against
different political and social ideas. Hacktivists publicly protest
against organizations or governments by posting articles, videos,
leaking sensitive information, and performing distributed denial of
service (DDoS) attacks.

Presentation_ID 20
Cybersecurity Criminals (Cont.)
Criminals come in many different forms. Each have their own motives:
▪ Cyber Criminals - These are black hat hackers who are either self-
employed or working for large cybercrime organizations. Each year,
cyber criminals are responsible for stealing billions of dollars from
consumers and businesses.
▪ State Sponsored Hackers - Depending on a person’s perspective,
these are either white hat or black hat hackers who steal government
secrets, gather intelligence, and sabotage networks. Their targets are
foreign governments, terrorist groups, and corporations. Most
countries in the world participate to some degree in state-sponsored
hacking.

Presentation_ID 21
Thwarting the cyber criminals is a difficult task, company, government
and international organizations have begun to take coordinated actions
to limit or fend off cyber criminals. The coordinated actions include:
• Vulnerability Database: The Nation Common Vulnerabilities and
Exposures (CVE) database is an example of the development of a
national database. The CVE National Database was developed to
provide a publicly available database of all know vulnerabilities.
http://www.cvedetails.com/
• Early Warning Systems: The Honeynet project is an example of
creating Early Warning Systems. The project provides a HoneyMap
which displays real-time visualization of attacks.
https://www.honeynet.org/node/960
• Share Cyber Intelligence: InfraGard is an example of wide spread
sharing of cyber intelligence. The InfraGard program is a partnership
between the and the private sector. The participants are dedicated to
sharing information and intelligence to prevent hostile cyberattacks.
https://www.infragard.org/
Cybersecurity Specialists

Presentation_ID 22
• ISM Standards: The ISO 27000 standards are an
example of Information Security Management
Standards. The standards provide a framework for
implementing cybersecurity measures within an
organization. http://www.27000.org/
• New Laws: The ISACA group track law enacted
related to cyber security. These laws can address
individual privacy to protection of intellectual
property. Examples of these laws include:
Cybersecurity Act, Federal Exchange Data Breach
Notification Act and the Data Accountability and
Trust Act.

organizations, provide services and protect people from
cyberattacks
▪ Cybersecurity specialists recognize the threat that data poses if
used against people
▪ A cybersecurity threat is the possibility that a harmful event,
such as an attack, will occur
▪ Cyber vulnerability is a weakness that makes a target
susceptible to an attack
▪ Cyber threats are particularly dangerous to certain industries
and the type of information they collect and protect

Presentation_ID 25
The following examples are just a few sources of data that can
come from established organizations:
▪ Personal Information
▪ Medical Records
▪ Education Records
▪ Employment and Financial Records
Common Threats
Threat Arenas (Cont.)

Presentation_ID 26
Network services like DNS, HTTP and Online
Databases are prime targets for cyber
criminals.
▪ Criminals use packet-sniffing tools to
capture data streams over a network.
Packet sniffers work by monitoring and
recording all information coming across a
network.
▪ Criminals can also use rogue devices,
such as unsecured Wi-Fi access points.
▪ Packet forgery (or packet injection)
interferes with an established network
communication by constructing packets to
appear as if they are part of a
communication.
Common Threats

▪ On a personal level, everyone needs to safeguard his or her
identity, data, and computing devices.
▪ At the corporate level, it is the employees’ responsibility to
protect the organization’s reputation, data, and customers.
▪ At the state level, national security and the citizens’ safety and
well-being are at stake.
▪ In the U.S., the National Security Agency (NSA) is responsible
for intelligence collection and surveillance activities.
▪ The efforts to protect people’s way of life often conflicts with
their right to privacy.
Common Threats

Presentation_ID 29
1.4 Spreading Cybersecurity
Threats

Presentation_ID 30
Spreading Cybersecurity Threats
How Threats Spread
Attacks can originate from within an organization or from outside of the
organization, as shown in the figure.
Internal Security Threats
▪ An internal user, such as an employee or contract partner, can
accidently or intentionally
▪ Internal threats have the potential to cause greater damage than
external threats because internal users have direct access to the
building and its infrastructure devices. Internal attackers typically have
knowledge of the corporate network, its resources, and its confidential
data. They may also have knowledge of security countermeasures,
policies and higher levels of administrative privileges.
External Security Threats
▪ External threats from amateurs or skilled attackers can exploit
vulnerabilities in networked devices, or can use social engineering,
such as trickery, to gain access.
▪ External attacks exploit weaknesses or vulnerabilities to gain access to
internal resources.

Presentation_ID 31
Vulnerabilities of Mobile Devices - In the past, employees typically used
company-issued computers connected to a corporate LAN.
▪ Today, mobile devices such as iPhones, smartphones, tablets, and
thousands of other devices, are becoming powerful substitutes for, or
additions to, the traditional PC.
▪ More and more people are using these devices to access enterprise
information. Bring Your Own Device (BYOD) is a growing trend.
▪ The inability to centrally manage and update mobile devices poses a
growing threat to organizations that allow employee mobile devices on their
networks.
How Threats Spread (Cont.)

Presentation_ID 32
▪ Emergence Internet-of-Things - The Internet of
Things (IoT) is the collection of technologies that
enable the connection of various devices to the
Internet.
▪ IoT technologies enable people to connect billions of
devices to the Internet. These devices include
appliances, locks, motors, and entertainment
devices, to name just a few.
▪ This technology affects the amount of data that
needs protection. Users access these devices
remotely, which increases the number of networks
requiring protection.
▪ With the emergence of IoT, there is much more data
to be managed and secured. All of these
connections, plus the expanded storage capacity
and storage services offered through the Cloud and
virtualization, has led to the exponential growth of
data.

Presentation_ID 33
Impact of Big Data – Big data is the result of data
sets that are large and complex, making traditional
data processing applications inadequate. Big data
poses both challenges and opportunities based on
three dimensions:
▪ The volume or amount of data
▪ The velocity or speed of data
▪ The variety or range of data types and sources
There are numerous examples of big corporate
hacks in the news. As a result, enterprise systems
require dramatic changes in security product
designs and substantial upgrades to technologies
and practices. Additionally, governments and
industries are introducing more regulations and
mandates that require better data protection and
security controls to help guard big data.

Presentation_ID 34
Advanced Weapons
▪ Advanced persistent threat (APT) is a continuous computer hack that occurs under the
radar against a specific object. Criminals usually choose an APT for business or political
motives.
▪ Algorithm attacks can track system self-reporting data, like how much energy a computer
is using, and use that information to select targets or trigger false alerts. Algorithmic
attacks are more devious because they exploit designs used to improve energy savings,
decrease system failures, and improve efficiencies.
▪ Intelligent selection of victims. In the past, attacks would select the low hanging fruit or
most vulnerable victims. Many of the most sophisticated attacks will only launch if the
attacker can match the signatures of the targeted victim.
Broader Scope and Cascade Effect
▪ Federated identity management refers to multiple enterprises that let their users use the
same identification credentials gaining access to the networks of all enterprises in the
group. The goal of federated identity management is to share identity information
automatically across castle boundaries.
▪ The most common way to protect federated identity is to tie login ability to an authorized
device.
Threat Complexity

Presentation_ID 35
Safety Implications
▪ There are many safety implication associated with the dark forces of cyber
security including emergency call centers in the U.S. are vulnerable to
cyberattacks that could shut down 911 networks, jeopardizing public safety.
▪ A telephone denial of service (TDoS) attack uses phone calls against a target
telephone network tying up the system and preventing legitimate calls from
getting through.
▪ The next generation 911 call centers are vulnerable because they use Voice-
over-IP (VoIP) systems rather than traditional landlines.
Heightened Recognition of Cybersecurity Threats
▪ The defenses against cyberattacks at the start of the cyber era were low. A
smart high school student or script kiddie could gain access to systems.
▪ Now, countries across the world have become more aware of the threat of
cyberattacks. The threat posed by cyberattacks now head the list of greatest
threats to national and economic security in most countries.
Threat Complexity (Cont.)

1.5 Creating More Experts

Presentation_ID 37
Creating More Experts
A Workforce Framework for Cybersecurity
Addressing the Shortage of Cybersecurity Specialists
▪ In the U.S., the National Institute of Standards and Technologies (NIST) created a
framework for companies and organizations in need of cybersecurity
professionals. The framework enables companies to identify the major types of
responsibilities, job titles, and workforce skills needed.
The Seven Categories of Cybersecurity Work
The Workforce Framework categorizes cybersecurity work into seven categories.
▪ Operate and Maintain includes providing the support, administration, and
maintenance required to ensure IT system performance and security
▪ Protect and Defend includes the identification, analysis, and mitigation of threats
to internal systems and networks
▪ Investigate includes the investigation of cyber events and/or cyber crimes
involving IT resources
▪ Collect and Operate includes specialized denial and deception operations and
the collection of cybersecurity information

Presentation_ID 38
A Workforce Framework for Cybersecurity
(Cont.)
▪ Analyze includes highly specialized review
and evaluation of incoming cybersecurity
information to determine if it is useful for
intelligence
▪ Oversight and Development provides for
leadership, management, and direction to
conduct cybersecurity work effectively
▪ Securely Provision includes
conceptualizing, designing, and building
secure IT systems
Within each category, there are several
specialty areas. The specialty areas then
define common types of cybersecurity work.

Presentation_ID 39
Online Cybersecurity Communities
Professional Organizations
▪ Cybersecurity specialists must collaborate with professional colleagues frequently.
International technology organizations often sponsor workshops and conferences.
Visit each site with your class and explore the resources available.

Presentation_ID 40
Online Cybersecurity Communities (Cont.)
Cybersecurity Student Organizations and
Competitions
▪ Cybersecurity specialists must have the
same skills as hackers, especially black hat
hackers, in order to protect against attacks.
▪ How can an individual build and practice the
skills necessary to become a cybersecurity
specialist?
▪ Student skills competitions are a great way to
build cybersecurity knowledge skills and
abilities.

Cybersecurity Certifications
Industry Certifications
In a world of cybersecurity threats, there is a great need for skilled and knowledgeable
information security professionals. The IT industry established standards for cybersecurity
specialists to obtain professional certifications that provide proof of skills, and knowledge
level.
▪ CompTIA Security+ - Security+ is a CompTIA-sponsored testing program that certifies
the competency of IT administrators in information assurance.
▪ EC-Council Certified Ethical Hacker (CEH) – CEH is an intermediate-level certification
asserts that cybersecurity specialists holding this credential possess the skills and
knowledge for various hacking practices.
▪ SANS GIAC Security Essentials (GSEC) - The GSEC certification is a good choice for
an entry-level credential for cybersecurity specialists who can demonstrate that they
understand security terminology and concepts and have the skills and expertise required
for “hands-on” security roles. The SANS GIAC program offers a number of additional
certifications in the fields of security administration, forensics, and auditing.

Presentation_ID 42
Cybersecurity Certifications (Cont.)
▪ (ISC)^2 Certified Information Systems Security Professional (CISSP) - The CISSP
certification is a vendor-neutral certification for those cybersecurity specialists with a
great deal of technical and managerial experience. It is also formally approved by the
U.S. Department of Defense (DoD) and is a globally recognized industry certification in
the security field.
▪ ISACA Certified Information Security Manager (CISM) – Cybersecurity specialists
responsible for managing, developing and overseeing information security systems at the
enterprise level or for those developing best security practices can qualify for CISM.

Presentation_ID 43
Company Sponsored Certifications - Another important credential for cybersecurity
specialists are company-sponsored certifications. These certifications measure knowledge
and competency in installing, configuring, and maintaining vendor products. Cisco and
Microsoft are examples of companies with certifications that test knowledge of their
products. Click here to explore the matrix of the Cisco certifications shown in the figure.
Cisco Certified Network Associate Security (CCNA Security) - The CCNA Security
certification validates that a cybersecurity specialist has the knowledge and skills required to
secure Cisco networks.

Presentation_ID 44
How to Become a Cybersecurity Specialist
Cybersecurity specialists must be able to respond to threats as soon as
they occur. This means that the working hours can be somewhat
unconventional. Cybersecurity specialists also analyze policy, trends, and
intelligence to understand how cyber criminals think. Many times, this
may involve a large amount of detective work. Here is good advice for
becoming a cybersecurity specialist:
▪ Study: Learn the basics by completing courses in IT. Be a life-long
learner. Cybersecurity is an ever-changing field, and cybersecurity
specialists must keep up.
▪ Pursue Certifications: Industry and company sponsored certifications
from organizations such as Microsoft and Cisco prove that one
possesses the knowledge needed to seek employment as a
cybersecurity specialist.
▪ Pursue Internships: Seeking out a security internship as a student
can lead to opportunities down the road.
▪ Join Professional Organizations: Join computer security
organizations, attend meetings and conferences, and join forums and
blogs to gain knowledge from the experts.
