Cybersecurity consists of two terms "Cyber"
means relating to the characteristic of
computers, information technology, etc., and
"Security" means protection or prevention. Thus,
Cybersecurity is the term used to protect the
systems connected to the internet, such as
hardware, software, and data, from cyber threats.
This practice of protecting these devices and
especially data is done by individuals and
enterprises to prevent unauthorized access for
attackers trying to enter into the system. A good
cybersecurity strategy adopted by the
organization can prevent the systems from
malicious attacks and stop further damage to the
company and its reputation.

About Cybersecurity Threats A cybersecurity
threat is a malicious attack performed by
attackers trying to gain unauthorized access to a
system or network to deface the IT assets,
company's sensitive data, and other intellectual
property. There are different types of
cybersecurity threats or attacks, they
are Malware Malware is that kind of malicious
software in which any kind of file or program is
used to harm a system. They may vary as per their
severity and can be in the form of viruses,
trojans, worms, spyware, etc. Ransomware
Ransomware is malicious software used to lock
users' system files through any kind of
encryption program. Cybercriminals then demand
payment to decrypt these system files. Social
Engineering Attack Social Engineering Attack is
the wide range of malicious activities
accomplished through human interactions. It uses
the psychological mindset of employees, tricks
them, and takes away the company's sensitive
information. Phishing In a Phishing Attack,  an
attacker sends fraudulent or fake emails from a
reputed source to the users to steal sensitive

DNS Attack DNS Attack is where the attacker
takes advantage of the vulnerabilities of the
Domain Name System (DNS) and redirects the users
to other malicious sites. There are various types
of DNS attacks like Domain Hijacking, DNS Flood
Attack, Cache Poisoning, DNS Tunneling, and DNS
Hijack Attack. Denial of Service (DoS) and
Distributed Denial of Service (DDoS) DoS attack
is the attack where the attacker floods the
systems, networks, or servers with massive
traffic of legitimate requests. In a distributed
denial-of-service (DDoS) attack,attackers attempt
to disrupt traffic of a normal server, network,
or service by overwhelming the target with
flooding of internet traffic. Man-in-the-middle-a
ttack Man-in-the-middle attack is a type of
attack where an attacker intercepts the message
from the intended source, modifies that message,
and that modified message is then sent to an
intended destination. The person from the
intended destination thinks that the message is
received from the intended source where the
content was modified. Wrap up Cybersecurity is
a challenging field where cybersecurity teams
have to keep their eyes peeled 24/7 as they have
to continuously monitor the threats in the
systems, network, and especially the valuable
assets of the organization. Attackers are
continuously keeping track of the vulnerabilities
of the system and then take advantage of this
situation and perform data breaches that are
creating huge financial and reputation losses for
the IT sector. So, the IT sectors should improve
their cybersecurity strategy so as to stop these
threats.
