A cyber-attack is a sort of exploitation of computer systems and networks. It employs malicious code to modify computer code, logic, or even that of data and head to cybercrimes, such as information and identity theft.
Certainly, you are living in a digital era and in this current time, most of the people use computer and internet. Due to the dense dependency on digital things, the illegal computer activity and diverse illegitimate moves are growing and changing like any kind of crime. There are so many types of cyber attacks that have emerged with the growth of internet usage. And if you do not know about at least the commonest ones, you may be the next victim. Here are some common types you would want to know right away.
Web-based threats and attacks
These are the attacks that happen on a website or web applications. Some of the critical web-based attacks are like:
DNS spoofing is a kind of computer security hacking. Wherein a data gets introduced into a dns resolver’s cache activating the name server to return a wrong ip address, diverting traffic to the computer of the hacker or any other computer. The DNS spoofing attacks may go on for a long period of time that to without getting detected and may activate serious security issues.
It is the attack wherein some of the data is going to be injected into a web application to operate and modify the application and gather the required information. Some of the examples of the same may be such as sql injection, code injection, log injection, xml injection and so on.
Denial of service
This is a type of attack that is specifically meant to make a server or network resource simply unavailable or invalid to the users. It achieves this by flooding the target with immense traffic or even sending it information that triggers a crash. It makes use of the single system and even single internet connection to attack a server. You can easily divide it into different sections such as: volume-based attacks, application layer attacks, protocol attacks, and so on.
Hijacking of sessions
This one is security attack on a user session via a protected network. Web applications create up cookies to store the state and user sessions. By stealing or taking away the cookies, an attacker may grab access to all of the user data.
This is a kind of attack which makes use of a trial and error sort of technique. Such an attack generates a huge number of guesses and legalizes them to obtain actual data such as user password along with personal identification number. Such an attack could be used by criminals to crack encrypted data, or by even security, analysts to test the safety of an organization’s network.
So, since you know much about different types of common cyber-attacks, make sure that you stay more vigilant and take the precautions needed. After all, the internet is not a safe place to be if you are not alert.
