This document discusses common types of network security attacks and provides advice on how to protect against them. It outlines seven main types of attacks: denial-of-service attacks, distributed denial-of-service attacks, man-in-the-middle attacks, packet sniffing, IP spoofing, port scanning, and SQL injection attacks. The document emphasizes the importance of organizations implementing appropriate network security measures like firewalls, intrusion detection systems, encryption protocols, and regular security audits to protect their networks and data from potential threats posed by these attacks.

There are different forms of network security attacks that threaten the security, privacy, and
accessibility of networks and the information they send.
Common types of attacks in network security
Among the most popular forms of network security threats
are:-
1. Denial-of-Service (DoS) Attacks
These attacks attempt to render a network or service unavailable by flooding it with traffic or
resource requests, leaving it unavailable to legitimate users.
2. Distributed Denial-of-Service (DDoS) attacks
DDoS assaults use a botnet of hacked systems to conduct a coordinated attack on a target network
or service, expanding the attack’s impact.
3. Man-in-the-Middle (MitM) Attacks
A MitM attack hits when an attacker intercepts and modifies communication between two parties
without their knowledge. It allows the attacker to eavesdrop in on conversations, modify data, or
impersonate one of the parties involved.
4. Packet Sniffing
Packet sniffing is the process of collecting and analysing network traffic in order to steal sensitive
information carried over the network, such as passwords, usernames, or financial data.
5. IP Spoofing
An attacker disguises their IP address to seem to be a trustworthy entity in IP spoofing. This allows
them to circumvent network security and obtain unauthorised access to systems.
6. Port Scanning
Port scanning involves a target network for open ports that can be used by attackers. This aids in
the identification of susceptible services or systems that can be exploited.
Phishing attacks use misleading methods, such as emails or websites that look authentic, to fool
people into disclosing sensitive information, such as login credentials or financial information.
7. SQL Injection Attacks
By injecting malicious SQL statements into input fields, attackers exploit vulnerabilities in web
apps to obtain unauthorised access to databases and potentially get sensitive data.
9. Cross-Site Scripting (XSS) Attacks
XSS attacks include the injection of malicious scripts into websites, which are subsequently
executed by the browsers of unsuspecting users. It enables attackers to steal data or take control
of user sessions.
10. Network Eavesdropping
Network eavesdropping is the practise of intercepting sensitive data passed over a network, such
as passwords, financial information, or intimate discussions.

Bottom line
It is crucial for organizations and individuals to be aware of these various types of attacks and
implement appropriate network security measures, such as firewalls, intrusion detection systems,
encryption protocols, and regular security audits, to protect their networks and data from potential
threats.
