Denial-of-service (DoS) attack
A threat actor launches a dos attack to shut down an individual machine or an entire network so that it's unable to respond to service requests. DoS attacks do this by flooding the target with traffic or sending it some information that triggers a crash. In addition, reconfiguring firewalls, routers and servers can block any bogus traffic. Keep routers and firewalls updated with the latest security patches.
Also, application front-end hardware that's integrated into the network can help analyze and screen data packets -- i.e., classify data as priority, regular or dangerous -- as they enter the system. The hardware can also help block threatening data.

7. Man-in-the-middle (MitM) attack
A man-in-the-middle attack is one in which the attacker secretly intercepts and alters messages between two parties who believe they are communicating directly with each other. In this attack, the attacker manipulates both victims to gain access to data. Examples of MitM attacks include session hijacking, email hijacking and Wi-Fi eavesdropping.
Although it's difficult to detect MitM attacks, there are ways to prevent them. One way is to implement an encryption protocol, such as TLS (Transport Layer Security), that provides authentication, privacy and data integrity between two communicating computer applications. Another encryption protocol is SSH, a network protocol that gives users, particularly system administrators, a secure way to access a computer over an unsecured network.

8. Password attack
This type of attack is aimed specifically at obtaining a user's password or an account's password. To do this, hackers use a variety of methods, including password-cracking programs, dictionary attacks, password sniffers or guessing passwords via brute force (trial and error).
A password cracker is an application program used to identify an unknown or forgotten password to a computer or network resources. This helps an attacker obtain unauthorized access to resources. A dictionary attack is a method of breaking into a password-protected computer or server by systematically entering every word in a dictionary as a password.

9. Web application attack
This is any incident in which a web application is the vector of the attack, including exploits of code-level vulnerabilities in the application as well as thwarting authentication mechanisms. One example of a web application attack is a xss. This is a type of injection security attack in which an attacker injects data, such as a malicious script, into content from otherwise trusted websites.
Enterprises should review code early in the development phase to detect vulnerabilities; static and dynamic code scanners can automatically check for these. Also, implement bot detection functionality to prevent bots from accessing application data. And a web application firewall can monitor a network and block potential attacks.

10. Advanced persistent threat (APT)
An APT is a prolonged and targeted cyberattack typically executed by cybercriminals or nation-states. In this attack, the intruder gains access to a network and remains undetected for an extended period of time.
The APT's goal is usually to monitor network activity and steal data rather than cause damage to the network or organization.
