Now that most of our methods and activities are available automatically and for use on the Internet, we need to be as careful as children to go across the street whenever we see a suspicious stranger. This precaution is even more important when looking at the level of statistics, claiming that about one third of the world’s computers are infected with some form of malware.
In the past we have covered the history of web exploitation and what the world has exploited the most, as well as security breaches and how they can affect different organizations. But today we’re going back to the basics – and exploring the biggest network security attacks you can face online.
The most common network security threats
1. Computer virus
We’ve all heard of them, and we all have our fears. For everyday Internet users, computer viruses are the most common network threat in cybersecurity. Statistics show that approximately 33% of household computers are infected with some form of malware, more than half of which are viruses.
2. Rogue security software
Rogue security software is malicious software that misleads users into believing that they have network security issues, usually with a computer virus installed on their computer or updated security measures. Are not the latest They then offer to install or update the user’s security settings.
3. Trojan horse
Metaphorically, “Trojan horse” means to deceive a person by inviting an attacker from a safe place to a safe area. In computing, it has a very significant meaning – a Trojan horse, or “Trojan”, is a malicious attacker code or software that allows users to hide behind a legitimate program and happily run it. does.
4. Adware and spyware
With “adware” we consider software that is designed to track the data of your browsing habits and, therefore, show you ads and pop-ups. Adware collects data at your discretion – and is even a legitimate source of revenue for companies that allow users to try out their software for free, but the ads displayed using the software with. Spyware works similarly to adware, but installs your information without your computer. This can include calligraphers, including personal information, including email addresses, passwords, and even credit card numbers, making them more vulnerable to identity theft.
5. Computer worm
Computer worms are fragments of malware programs that rapidly reproduce and spread from one computer to another. A worm spreads from an infected computer by sending itself to all the contacts on the computer, then immediately to the contacts of other computers.
6. DOS and DDOS attack
There are really cases where a website’s server gets more traffic and just crashes, sometimes when a news story breaks. But more commonly, this is what happens to a website during a DOS attack, or a denial of service, when attackers attack a website with a traffic jam. When a website has a lot of traffic, it is unable to offer its contents to visitors.
The DDoS attack, or distribution-denial-of-service attack, is similar to DoS, but more powerful. The DDOS attack is difficult to control. It has been launched from many computers, and the number of computers involved can range from just a couple of thousands to thousands or more.
7. Phishing
Phishing is a form of social engineering that involves obtaining sensitive data such as passwords, usernames, and credit card numbers. The recipient of the email is then tricked into opening a malicious link, which installs malware on the recipient’s computer.
8. Rootkit
Rootkit is a set of software tools that enables remote control and management level access on a computer or computer networks. Once the remote is accessed, the root kit can perform a number of malicious actions. They are equipped with key loggers, password thieves and people with disabilities with anti-virus.
9. SQL injection attack
SQL Injection attack are designed to target data-driven applications by exploiting security vulnerabilities in application software. They use malicious code to obtain private data, alter or even destroy that data, and may invalidate transactions on websites. This has become a very serious privacy issue for data privacy.
10.MIM attacks
Intermediate attacks are cybersecurity attacks that allow the attacker to communicate between two targets. It can listen to a communication that is private in normal settings.
For example, an intermediate attack occurs when the attacker seeks to block any contact between person A and person B. Person A sends his public key to Person B, but the attacker intercepts it and sends a fake message. Person B represents A, but instead contains the attacker’s public key. B assumes that the message came from person A and encrypts the attackers with the public key, sends it back to A, but the attacker intercepts the message again, sending the message to the private key Opens from, possibly modifies, and re-encrypts using it. The public key was first provided by Person A. Again, when the message is passed back to person A, they believe it came from person B, and thus, there is an attacker between us that expands the communication between the two targets.
