Communication Network & Attack Surface
There are several common types of attacks on computer networks. Here are some of the most well-known ones:
Denial-of-Service (DoS) and Distributed Denial-of-Service (DDoS) Attacks: These attacks aim to overwhelm a network, server, or website with a flood of traffic, rendering it inaccessible to legitimate users.
Malware Attacks: Malicious software, such as viruses, worms, trojans, ransomware, or spyware, can infiltrate a network to disrupt operations, steal information, or gain unauthorized access.
Phishing Attacks: Phishing involves tricking users into revealing sensitive information, such as login credentials or financial details, by impersonating a legitimate entity through fraudulent emails, websites, or messages.
?Man-in-the-Middle (MitM) Attacks: In MitM attacks, an attacker intercepts and relays communication between two parties without their knowledge. This enables them to eavesdrop, modify data, or impersonate one of the parties involved.
SQL Injection Attacks: By inserting malicious SQL code into a vulnerable application or website, attackers can manipulate the underlying database, gain unauthorized access, or retrieve sensitive information.
Cross-Site Scripting (XSS) Attacks: XSS attacks occur when malicious scripts are injected into web pages viewed by users, allowing attackers to execute scripts within the victim's browser and potentially steal sensitive information.

Password Attacks: These attacks involve various techniques like brute-forcing, dictionary attacks, or using stolen credentials to gain unauthorized access to user accounts or network resources.
Network Sniffing: Attackers use network sniffing tools to intercept and capture network traffic, enabling them to analyze the data and potentially extract sensitive information, including passwords or confidential data.
Social Engineering Attacks: Social engineering relies on manipulating human psychology to trick individuals into revealing sensitive information or performing actions that compromise network security. Examples include impersonation, pretexting, or baiting.
Zero-day Exploits: Zero-day vulnerabilities are software vulnerabilities unknown to the vendor and, therefore, lack patches or fixes. Attackers exploit these vulnerabilities before they are discovered and patched, gaining unauthorized access to systems.
?It's important to note that the field of cybersecurity is continuously evolving, and attackers may develop new techniques or variations of these attacks. It is crucial for organizations and individuals to stay informed about the latest security threats and employ appropriate countermeasures to protect their networks.
