Cyber Attack: A Overview
Cyber attacks refer to any type of offensive maneuver employed by individuals or whole organizations that targets computer information systems, infrastructures, computer networks, or personal computer devices. Cyber attacks use malicious code and computer viruses to alter computer code, logic, or data, resulting in disruptive consequences that can compromise data and lead to cybercrimes, such as information and identity theft.
Types of Cyber Attacks
There are various types of cyber attack methods that malicious individuals and groups may use. These include:
- Malware: Malware, short for malicious software, is any software used to disrupt computer operations, gather sensitive information, or gain access to private computer systems. Common malware types include viruses, worms, Trojan horses, ransomware, spyware and adware.
- Social Engineering: Social engineering is the practice of deceiving someone in order to gain access to their sensitive data or systems. Attackers may attempt to gain access to a system by impersonating a known individual, sending deceptive emails, or using phishing techniques to trick people into providing their credentials.
- Phishing: Phishing is a type of social engineering attack used to steal sensitive data, such as usernames, passwords, credit card information, and bank account details. Attackers often use deceptive emails or malicious websites to lure users into providing personal information.
- Denial of Service Attacks: Denial of service attacks, also known as DoS attacks, are designed to overwhelm a system with malicious requests or traffic. This can cause the system to be unavailable to users or prevent them from accessing the system.
- Distributed Denial of Service Attacks (DDoS): DDoS attacks use multiple computers to send massive amounts of malicious requests or traffic to a system in order to prevent users from accessing it.
- Man-in-the-Middle Attacks (MITM): MITM attacks take place when an attacker intercepts a communication session between two systems. The attacker can then eavesdrop on the communication or alter the packets being sent and received.
- SQL Injection: SQL injection is a type of attack used to take control of a database. Attackers can access the database by inserting malicious SQL commands into an injection field or web form.
- Zero Day Attack:zero day attacks, also known as zero hour attacks, are attacks that exploit an unpatched vulnerability in software or hardware systems.
Implications of a Cyber Attack
The consequences of a successful cyber attack can be far-reaching and long-lasting. A successful cyber attack can lead to data and identity theft, loss of reputation, legal and financial repercussions, and damage to critical infrastructure. It can also have a significant negative effect on consumer trust and confidence in a company.
How to Prevent Cyber Attacks
In order to protect against cyber attacks, it is important to have the right security measures in place. These measures include strong authentication and password policies, effective access controls, regular system updates and patches, intense monitoring of system activities, and user training and awareness. It is also important to have reliable backup and recovery plans in place.
