What is Cyber Attack?
Any action conducted by cybercriminals with malevolent intent is referred to as a cyber-attack. Cybercriminals use one or more computers to initiate attacks on other computers, networks, or information systems.
A cyber assault may be launched using a number of ways, but the common aims are to:
- Data thievery
- Destroy data or information
- Disable computers and change data
- Obtain monetary gain
Why do Cyber Attacks Keep Happening?
The majority of cyber attacks are either criminal or political in nature. An adversary might be a private individual, a governmental actor, or a criminal organization. However, considering the intentions behind these attacks is the most crucial component in understanding why they occur. Because thieves do not always seek the same thing, there is no one-size-fits-all solution to the issue of why cyber attacks happen.
Some cybercriminals are looking for money or information, while others may just wish to launch attacks. Disgruntled ex-employees, for example, hack systems in order to ruin them for personal reasons.

Cyber Attacks that are Often Used
There are many different kinds of cyber attacks, but some are more prevalent than others. Malware, ransomware, denial of service, and phishing are among the most prevalent threat activities.
- Active vs. Passive attacks
Consider the two broad categories, passive and aggressive, before diving into the various sorts of cyber security attacks. Passive assaults do not target the system’s resources; instead, they seek to uncover information. Active attacks, on the other hand, try to compromise a system’s Confidentiality, Integrity, or Availability.
- Distributed Denial of Service
When hackers attempt to deny access to a website or server, this is known as a distributed denial of service (DDoS) assault. To do this, fraudsters utilize a variety of technologies to overwhelm the targeted system, rendering it inaccessible to genuine users.
Man in the Middle
The cybercriminal gets between the online service and the user in this form of cyber attacks. An attacker may, for example, create a Wi-Fi login page on a public network to imitate the actual thing. The cybercriminal may view the information the victim enters, including critical passwords, after the victim checks in.
Phishing is a sort of cyber security attack that is quite widespread. This usually entails sending emails that look to be from the government but are really from cybercriminals, requesting for personal information. Regrettably, even as spam filters improve, fraudsters find new methods to get through them.
Ransomware is a sort of malware or malicious assault that encrypts data on a victim’s computer. The fraudsters then demand payment in return for the data being unencrypted.
- Zero-day exploits
These occur when attackers take advantage of software flaws that have yet to be addressed by the creators.
How to Avoid a Cyber Attacks
The good news is that, although cyber attacks pose a serious threat, there are several techniques for preventing them. You may take adequate safeguards by understanding what a cyber assault is and the most typical techniques and tactics utilized. Here are some of our greatest cyber-security advice and how to defend yourself from cyber-attacks.
- Data Backup: Backup can help in many situations, such as if hackers delete or replace data after hacking your data, then if you have backup then it reduces ransomware attack.
- Control System Access: You may also lower your risk of a cyber attack by being careful with system access, such as revoking access as soon as someone leaves the firm and implementing tight role-based access control. This may prevent unhappy ex-employees from behaving maliciously and ensure that only the correct individuals have access to sensitive information.
- Two-factor authentication: If hackers discover passwords, two-factor authentication prevents them from obtaining access to your network or devices. This is especially critical for businesses where there is a significant danger of phishing emails.
- Use firewalls and antivirus: Antivirus and firewall software should be install all the devices connect to your company’s network. By identifying malware and eliminating other dangers, this adds another layer of security.
