A security breach occurs when an unauthorized person gets access to your computer data, applications, networks, or devices. A security breach can lead to things like system damage and data loss and can also damage an organization’s reputation or finances.
A security and data breach is the worst thing that can happen to any organization or its customers. A security breach can also make an organization face reputational loss.
What are the types of Security Breaches?
Below are the different types of security breaches that an attacker can initiate:
Denial of service (DoS) attacks:
A Denial of Service is a cyber-attack in which the attacker with malicious aim makes the machine or network resource unavailable to its intended users by flooding the target network with heavy traffic.
The DoS attacks typically exploited the security vulnerabilities present in the network or system. The victims of DoS attacks are often high-profile organizations such as banking, commerce, government, and trade organizations.
Types of DoS attacks can be Volumetric attacks, Fragmentation Attacks, TCP-State Exhaustion Attacks, Application Layer Attacks.
Impersonation of an organization:
Sometimes cybercriminals can create a gap in security by sending a fake email but convincing, to any employee of the organization.
The email can contain any link which will make the employee enter any of the login details or any other sensitive information, which can lead the attacker to enter the system. This technique is also known as phishing.
Virus, spyware, and malware are often used by cybercriminals to break into the protected network to find data, destroy or take down a whole system. They mostly arrive from any download from the internet or from email. If it’s a virus it can also to other computers within your network.
It is recommended that you shouldn’t download anything from the internet or click on any link you find embedded in your email.
