3. Introduction
Computer systems are constantly protected against various cyberthreats by professionals in cyber
security. Every day, private systems and enterprises are the targets of cyberattacks, whose variety
has rapidly expanded.
There are two categories of businesses, according to former Cisco CEO John Chambers: those that
have been hacked and those who are still unaware that they've been attacked (Cisco, 2021).
Cyberattacks can have a variety of purposes. There are two. Cyber criminals may take a system
offline and demand money to make it functional again. More complex than ever, ransomware is an
assault that demands payment to unlock in order to restore services.

4. Cyber-attacks targetsboth businesses and individuals, often as a result of
the personal information people save on their mobile devices and the usage
of unsecure public networks (Almaiah et al., 2021).
To improve cyber security, it is essential to monitor changing and more
frequent cyberattacks. An online cyber security master's degree may be
quite helpful for workers working to expand their understanding of dangers
and cyber security information.
Graduates of the online Master of Science in Cyber Security programme at
the University of North Dakota may anticipate acquiring a thorough and
sophisticated knowledge of cyber-attack techniques.

5. What Is a Cyber Security
Threat?
Any potential malicious attack that aims to gain
unauthorised access to data, interfere with digital
activities, or contaminate information is referred to as a
cyber security threat.
Cyber threats may come from a variety of sources,
including corporate espionage, hacktivists, terrorist
organisations, adversarial nation-states, criminal
organisations, lone hackers, and aggrieved individuals.

6. Sensitive data was disclosed as a result of multiple high-profile cyberattacks in recent years.
143 million people's personal information, including birth dates, addresses, and Social Security
numbers, were leaked in the 2017 Equifax breach, for instance.
Marriott International said in 2018 that hackers had gained access to its systems and taken
data from almost 500 million customers.
In all cases, the organization's inability to develop, test, and retest technological measures
including encryption, authentication, and firewalls allowed the cyber security danger to persist
(Banyal et al., 2020).
Cyber security experts are crucial for maintaining the security of private data since cyber
attackers might utilise sensitive data to steal information or access bank accounts of an
individual or a corporation, among other potentially detrimental acts.

8. 7 Types of Cyber Security
Threats
The following categories of cyber security dangers should
be thoroughly understood by cyber security professionals.
Malware, which includes spyware, viruses, ransomware,
and worms, is harmful software. When a user clicks on a
malicious link or attachment, harmful software is
installed, and malware is triggered. According to Cisco,
once triggered, malware can:

Install more malicious software.
Collect data secretly by sending data from the storage device (spyware)
Individual components can be harmed, rendering the system useless.
A cyber-attack known as a denial of service (DoS) bombards a computer or network with
requests, preventing it from responding. The same technique is accomplished via a distributed DoS
(DDoS), except the assault comes from a computer network. Flood attacks are frequently used by
cyber attackers to disrupt the "handshake" procedure and do a DoS.
There are several other methods that may be employed, and some cybercriminals make use of
networks being down to conduct additional attacks (Li & Liu, 2021) . According to Jeff Melnick of the
information technology security software business Netwrix, a botnet is a sort of DDoS in which
millions of devices may be infected with malware and managed by a hacker. The processing
power of a target is targeted and overpowered by botnets, also known as zombie computers.
Botnets are difficult to track down and spread over several places.
Denial of Service

10. Emotet is described as "an sophisticated, modular banking Trojan that primarily serves as a
downloader or dropper of other banking Trojans" by the Cybersecurity and Infrastructure
Security Agency (CISA). Emotet is still among the priciest and most harmful spyware.
When hackers interject themselves into a two-party transaction, a man-in-the-middle
(MITM) assault takes place. According to Cisco, they may filter and take data after disrupting
the transmission. When a visitor makes use of an unprotected public Wi-Fi network, MITM
assaults frequently happen. Attackers place themselves in the way of the visitor and the
network, then employ malware to set up dangerous software and access data (Podder et al.,
2021).

Man in the Middle

11. A specific kind of cyberattack called a Structured Query Language (SQL) injection happens
when malicious code is inserted into a server that supports SQL. The server divulges
information when infected. Simply typing the malicious code into a search box on a
susceptible website can submit it.
Phishing attacks employ fake correspondence, such an email, to con the recipient into
opening it and following the instructions contained therein, like entering a credit card
information. According to Cisco, the intention is to steal personal information like credit card
numbers and login credentials or to infect the victim's computer with malware.
SQL Injection
Phishing

12. An online hacker may gain access to a variety of data with the proper password. Data Insider
describes social engineering, a sort of password assault, as "a tactic cyber attackers utilise
that depends largely on human connection and frequently entails persuading individuals into
violating basic security measures." Accessing a password database or guessing a password
straight are two more methods of password attacks (Patil et al., 2020).
Therefore, to safeguard their operations and data, businesses and government bodies
require the highest level of cyber security. For cyber security specialists, it is crucial to
comprehend how to handle the most recent, changing cyber threats.
