Network Attacks

Network Attack Types Your data may be attacked if security precautions and controls are not in place. In some attacks, information is monitored; in others, it is actively changed with the intention of corrupting or destroying the data or the network itself. Active and passive attacks

Passive attacks - No content alteration or fabrication - Eavesdropping to obtain information or other information (such as traffic trends and transfer patterns)

Active attacks - Altering the content of or taking part in conversation with ?Pose as trustworthy parties ?Change the text while it's being sent Start denial-of-service assaults.

If you don't have a security plan in place, your networks and data are susceptible to any of the following attacks: Most network communications take place in an unsafe environment, or "clear-text" style, which permits a perpetrator who accessed your network's data paths to "listen in" or read and understand the traffic. When someone is listening in on your conversation it is referred to as spying or sniffing during communications. An eavesdropper's capacity to keep track of the network is typically, administrators' main security issue is face in a business. Your data can be viewed by others as it travels across the network if there are no reliable encryption services based on cryptography.

Modification of Data The logical next step for an attacker is to modify your data after they have read it. Without the sender or receiver's knowledge, an attacker can change the data in a packet.

Identity spoofing (IP address spoofing) The IP address of a computer is typically used by networks and operating systems to identify a legitimate entity. Identity spoofing is a technique that can occasionally lead to a bogus IP address being assumed. With a valid IP address, the attacker can connect to the network and change, redirect, or erase your data.

Attacks Based on Passwords Password-based access control is a staple of most operating system and network security strategies. This implies that your user name and password—which together make up your identity—determine your access rights to computers and network resources. What happens if a hacker learns or guesses your password?

A denial-of-service attack Prohibits authorized users from using your computer or network as normal. The attacker can do any of the following after they have gained access to your network. Sending invalid data to network services or apps results in abnormal termination or behaviour of those services or applications, flood a computer or the entire network with traffic up until the overload forces a shutdown. Blocking traffic prevents authorized users from accessing network resources.

Man-in-the-Middle attack as the name suggests, a man-in-the-middle attack happens when someone is actively seeing, recording, and transparently managing your communication while it is being exchanged between you and the other party. The attacker could, for instance, re-route a data exchange. Attacks when someone assumes your identity in order to read your message are known as man-in-the-middle attacks. Because the attacker may be actively replying as you in order to continue the conversation and get additional information, the person on the other end may mistake it for you

What is an Eavesdropping the act of surreptitiously or covertly listening to another person's private discussion or communication without that person's consent in order to obtain information is known as Eavesdropping

Encrypted Scheme Attacks These attacks try to decrypt the encrypted data or extract the plain-text from the cipher-text. By identifying vulnerabilities and defects in cryptography methods, cryptographic protocols, encryption algorithms, or key management strategies, hackers may try to circumvent the security of a cryptographic system.
