- DoS- Denial of service
A security event that occurs when an attacker sends a high volume of traffic to a network preventing legitimate users from accessing targeted computer network and devices are termed as Denial of service. The end result is to shut down the system as it gets consumed with more than expected volume of traffic.
The high volume of traffic can be from one source or multiple sources, this is known as distributed denial of service (DDoS). The main goal is to disrupt the established business causing unnecessary harm to the target audience, unlike other attacks which are done for monetary gains. This type of attack is called as Phlashing.
- Man in the Middle Attack
This type of attack occurs when you are on the internet. When you are on the internet, you are communicating with web server host. While surfing the internet, we tend to go back and forth. Sometimes the server asks for login credentials genuinely required. This is where the attacker act as a middleman hijacking the website secured and encrypted pages to steal away important bank details. The hacker orchestrates a unique session ID where the user gets fooled with the look of the website without realizing it’s not the genuine site.

Always log out of the important application on your phone and laptop when not in use. Also, pay close attention if the website is redirecting to a page which doesn’t look original.
