Network Attacks
A network attack is an endeavor to gain unapproved access to an organization's network, with the goal of stealing data or perform other malicious activity. In this article, we will talk about the basic types of network attacks
Network security guarantees to protect data during transmission and to ensure that data transmissions are authentic and not altered by attackers.
Types of Network Attacks
Security is an important piece of your organization. Indeed, even you don't have the foggiest idea about the importance of network security until your organization is a victim of a network attack.
(1) Computer Virus
A computer virus is a software program that can spread starting with one computer then onto the next computer or one network to other networks without the user's knowledge and performs malicious actions. It has the ability to corrupt or harm data, obliterate files, format hard drives, or make plates unreadable.
How Does a Computer Virus Spread?
There are many ways that a virus or computer virus can be spread, which are as per the following:
- Clicking on an executable file
- Visiting an infected website
- Viewing an infected website advertisement
- Infected removable storage devices, such USB drives
- Opening spam email or an email attachment
- Downloading free games, toolbars, media players and other system utilities
(2) Man in the Middle (MITM) Attack
A Man in the Middle is a sort of cyber-attack where a malicious attacker inserts a conversation among sender and recipient, imitates both sender and collector, and gains access to their information.
In this attack, both sender and collector appear to convey ordinarily. The sender doesn't understand that the recipient is a malicious attacker and attacker trying to access or alter the message before re-transmitting to the collector.
The regular form of Man in the Middle attack is online communication, for example, email, web browsing, social media, and so forth.
IP Spoofing
Spoofing is another sort of cyber-attack where an attacker endeavors to utilize a computer, device, or network to deceive other system networks by masquerading as a legitimate user.
There are a few sorts of spoofing; IP spoofing is one of the most well-known.
IP Spoofing is an attacking technique where the hacker gains access to a computer network by sending messages to a computer with an IP address. The IP address indicating that the message is coming from a believed host so it would appear that it is authentic.
In an IP spoofing attack, a hacker first finds out an IP address of a confided in the host and then change the bundle headers with the goal that apparently the parcels are coming from that confided in the host.
(3) Malware
Malware is comprised of software program or code which is created by cyber attackers. It is intended to broad harm to systems or to gain unapproved access to a computer network.
The malware is delivered in the form of a link or file over email and it requires the user to click on the link to execute the malware. There are various sorts of malware, for example, computer viruses, worms, Trojan horses, spyware, and more.
(4) Trojan Horse
A Trojan horse is a sort of malicious code or program created by hackers to disguise as legitimate software to gain access to victim's systems. It is intended to erase, adjust, harm, block, or some other hurtful action on your data or network.
The victim gets an email with a connection that is looking official email. The connection can contain malicious code that is executed when the victim clicks on the connection file.
(5) Computer Worm
A computer worm is a kind of network attack that spreads within its connected network and duplicates itself starting with one computer then onto the next computer.
It can reproduce itself with no human assistance and it doesn't have to join itself to a software program in request to cause harm data.
Worms can exploit the security gaps of the software and trying to access in request to stealing sensitive information, corrupting files, and installing a secondary passage for remote access to the system.
(6) Denial-of-service (Dos) Attack
A Denial-of-Service is an attack that shut down a machine or network and making it inaccessible to the users. It regularly flooding a focused on a system with requests until typical traffic can't be processed, resulting in denial-of-service to users.
It happens when an attacker keeps legitimate users from accessing explicit systems, devices, or other network assets.
(7) Phishing
Phishing is a sort of social engineering attack that endeavor to gain sensitive and secret information, for example, usernames, passwords, credit card information, network credentials, and so more.
In a phishing attack, an attacker sends phishing emails to victims in request to steal login credentials and account information.
(8) Rootkit
A rootkit is a malicious program that installs and executes code on a system without user assent in request gain system access to a computer or network.
It is regularly installed by exploiting system vulnerabilities, social engineering strategies, and stolen passwords or phishing techniques without the victim's knowledge.
There are various sorts of Rootkit virus, for example, Bootkits, Firmware Rootkits, and Kernel-Level Rootkits and Application Rootkits.
(9) Logic Bombs
A logic bomb is a malicious program or bit of code inserted into an operating system or computer network which impacts a malicious function after a certain measure of time.
The code can be inserted into the existing software or into other forms of malware, for example, viruses, worms or Trojan horses, and so on.
Its main intention is deleting or altering data, reformatting a hard drive and creating other malicious follows up on a predetermined date
(10) Ransomware
Ransomware is a sort of malicious software or IT security threat that blocks to access the computer systems and demands for bitcoin in request to access the system.
The most perilous ransomware attacks are WannaCry, Petya, Cerber, Locky and CryptoLocker, and so forth.
Over a wide range of attack normally installed in a computer system through the following ways:
- When download and open a malicious email connection
- Install an infected software or apps
- User visits a malicious website or link
- Click on untrusted web link or images
