Understand common wireless/network attacks and implement basic prevention techniques.

You are a Cyber Security Analyst at SecureXit tasked with assessing a test network environment after unusual network activity was detected.

As part of this assessment, you will study common network attacks such as DoS, MITM, Wi-Fi attacks, and packet sniffing, perform network scanning and traffic analysis, identify network and wireless vulnerabilities, and apply basic security controls to reduce risks.

The findings will help strengthen network security, improve wireless configurations, and enhance the organization's ability to detect and mitigate network-based threats.

Topic : Cyber Threats and Attack Vectors

1) Different types of Malware Threat.

2) Overview of social engineering attacks.

3) Wireless & Network Attacks and prevention.

Open a terminal on the attacker machine and switch to the root user.

Verify connectivity with the target machine.

Confirm that all packets are successfully received before proceeding.

Launch an ICMP flood against the target machine.

Allow the attack traffic to run for approximately 30–60 seconds.

Observe that hping3 reports flood mode activity.

Launch an ICMP flood against the target machine.

Start packet capture for ICMP traffic.

Observe incoming ICMP Echo Requests from multiple source addresses.

Return to the attacker machine.

Launch a SYN flood against TCP port 80.

Let the attack run briefly and observe the packet generation.

On the target machine, open a terminal.

Start packet capture for  SYN traffic.

Observe the Flood on target machine Using

Great job!

You have successfully completed your lab on Extracting System Information Using Enumeration Techniques.

In this lab, you have: Discovered Active Hosts, Identified Open TCP/UDP Ports, Performed Service and OS Enumeration, Enumerated Users and Shared Resources, Gathered Information using rpcclient and enum4linux, and Conducted DNS and Domain Enumeration using dig, nslookup, and whois.

You are now ready to move to the next stage of Vulnerability Assessment and Security Testing.

Topic : Enumeration and Vulnerability Assessment

1) Enumeration techniques.

2) Identifying vulnerabilities.
