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 information such as login
credentials, credit card, and bank account details. There are various types of phishing
attacks like email phishing, spear phishing, whaling, smishing, vishing, and
angler phishing.
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-attack: 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.
