3. RANSOMWARE
Malicious software known as "Ransomware" encrypts files or
locks down a user's computer and then demands money
(often in cryptocurrency) to unlock or decode the files. Via
phishing emails, hacked websites, software flaws, it gains
access to systems. When it is engaged a ransom message
with payment instructions is displayed along with data
encryption, making the data unreadable. Attacks using
ransomware have the potential to ruin companies
compromise private data and result in losses of money.
Regular backups, strong cybersecurity defenses, phishing
awareness training for staff members and timely software
updates to fix vulnerabilities are all part of mitigation With no
assurance that data will be restored, recovering from
ransomware frequently necessitates paying the ransom or
depending on backups.

4. PHISHING ATTACKS
Phishing attacks are dishonest attempts to trick people into
disclosing private information, such credit card numbers,
passwords or personal information. These assaults usually take
the form of impersonation attacks on websites, instant
messaging apps or email accounts. Cybercriminals use a
variety of enticing strategies to trick their victims, such as phone
advertising, urgent demands, frightening messages.
Once the victim falls for the bait and divulges their personal
information, it may be used for financial fraud, identity theft or
illegal account access. Phishing is still a serious danger to IT
security therefore minimizing risks and guarding against
breaches requires alertness knowledge and strong security
measures.

5. DATA BREACHES
In terms of IT security data breaches refer to the unlawful
acquisition, revelation or stealing of private data that is kept
electronically. These breaches jeopardize the availability,
confidentiality and integrity of data, resulting in monetary
losses harm to an organization's or an individual's reputation
and potential legal repercussions. Attackers obtain valuable
data, including financial records, Intellectual property and
personal information by taking advantage of flaws in
systems, networks or human error.
To reduce risks and guard against possible breaches,
preventive measures include strong encryption, access
controls, frequent audits and employee training. These steps
ensure the security of sensitive data and uphold confidence
in digital environments.

6. INSIDER THREATS
In the context of IT security, insider threats are dangers
posed by people who work for an organization as partners,
contractors or employees and who abuse their access to
compromise networks, systems or data. These risks
might be deliberate such as hostile insiders looking to steal
confidential data or interfere with operations or they can be
incidental such staff members falling for social engineering
schemes or making careless mistakes that jeopardize
security.
Because insiders frequently have legitimate access to
systems and may take advantage of their expertise with the
organization's architecture, insider threats are difficult to
identify and counter. A combination of technology
restrictions, personnel training, ongoing monitoring makes
up effective security measures.

7. SUPPLY CHAIN ATTACKS
In IT security, supply chain attacks entail taking use of flaws in a
system's vendors or suppliers to breach the network of the
intended enterprise. In order to introduce malicious code or alter
items before they are delivered to end customers, attackers
compromise reliable third-party software or hardware vendors.
This gives them the ability to enter networks without
authorization, steal confidential information or interfere with
regular business activities.
Because these attacks can evade conventional security
safeguards and impact multiple businesses at once they
represent serious concerns. Vigilant supplier vetting the use of
secure development processes and constant attention to
suspicious activity in the supply chain are examples of
preventive measures.

8. DDOS ATTACKS
Malicious attempts referred to as DDoS (Distributed Denial
of Service) assaults aim to stop a network, server or
service from operating normally by flooding it with traffic
from numerous sources. The target's resources are
depleted by this torrent of traffic, rendering it unavailable to
authorized users. DDoS assaults have the potential to
cause major disruptions, monetary losses and
reputational harm to a company.
Attackers frequently plan these attacks using hacked
devices or botnets. To protect against such threats,
mitigation solutions include traffic filtering, strong
network security measures, the deployment of specialized
DDoS protection services to identify and stop malicious
traffic.
