Types of Network Security Attack

The following is 10 of the common ways cybercriminals can attempt to target your network:

1. Trojan Horse

A Trojan horse is a malicious program that appears to be useful and installed on a computer. Because of their innocent look, users are encouraged to press and download the software. After installing the software, a range of functions such as the stole of information, keystrokes monitoring or manipulation of data is performed in the database.

2. Malware

Malware attacks are among the most serious cyberattacks designed especially to disable or access a targeted computer system unauthorized. The most popular malware is self-replicating, i.e. It gets access via the internet while infecting a certain device and from there it contaminates all network- connected systems. An additional endpoint computer will also become infected if it is connected. It runs faster than the others.

3. Botnet

It’s a private computer network that is a victim of malware. By knowing the user, the hacker controls all machines on the network. Every network machine is called zombies because it is intended to spread, infect or lead the attacker on large numbers of computers.

4. Man in The Middle

A man in the middle attack is someone standing between you and the other personal interaction. By being in the center, an intruder may easily intercept, monitor and control the communication; for example, the device in the layer may not be able to determine the receiver with which they exchange information when the lower layer of the network sends information.

5. Packet Sniffer

If a passive receiver is mounted on the wireless transmitter’s land, it will store copies of each transmission packet. Such packages may include confidential information, sensitive and critical information, commercial secrets, etc. It will get through it when it flies across a packet receiver. The receiver acts as a sniffer to the packet and then sniffs all the packets that are sent to the sector. Cryptography is the most effective protection against sniffers.

6. IP Spoofing

This method uses a fake source address to insert packets into the Internet and is one way to masquerade them as another user. End-point authentication which guarantees that a message from the location we have decided is certain would help to protect against IP spoofing.

7. DOS (Denial of Service)

A Denial-of-Service is a critical attack that completely or partially kills the victim’s network or the IT infrastructure to block authorized users from accessing it. The Dos attack divided into three parts which are as follows:

Bandwidth Flooding: Through sending a cascade of packets the terrorist attacker can block valid packets from accessing the server. The transmitted packets are wide so that the connection for other people is blocked.

Vulnerability Attack: When a few well-formed messages are sent to the insecure operating system or to the device on the target server, the service fails or gets worse if the host collapses.

Connection Flooding: By creating large numbers of TCP connections on the targeted server, the attacker is bogging down. These fake connections block the network and prevent legitimate users from using it.

8. Distributed Denial of Service 9. Worm

Without user support, a worm will reach a computer. If a user runs a vulnerable network program, a malware attacker may send malware to that application on the same Internet connection. The application will accept and execute malware from the internet to build a worm.

10. Virus Conclusion

In this article, we have seen different types of network types which are harmful to networks as well as system. I hope you will find this article helpful.
