Scanning and enumeration in Cybersecurity - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to identify the tool used for scanning open ports.

Cybersecurity

The command 'nmap [1] 192.168.1.1' is used to scan open ports on a target.

Drag options to blanks, or click blank then click option'

B-sS

C-v

D-o

💡 Hint

Common Mistakes

Using '-p' which specifies ports but does not perform the scan type.

Using '-v' which increases verbosity but does not scan.

Using '-o' which is for output options.

The option -sS in nmap performs a TCP SYN scan, which is commonly used to scan open ports stealthily.

Complete the sentence to describe enumeration.

Cybersecurity

Enumeration is the process of [1] information about a target system after scanning.

💡 Hint

Common Mistakes

Choosing 'ignoring' which is the opposite of enumeration.

Choosing 'hiding' or 'deleting' which are unrelated actions.

Enumeration involves gathering detailed information such as usernames, shares, and services after initial scanning.

Fix the error in the command to perform a UDP scan.

Cybersecurity

nmap [1] 192.168.1.1

Drag options to blanks, or click blank then click option'

A-sS

B-sN

C-sU

D-sT

Attempts:

💡 Hint

Common Mistakes

Using '-sS' which is for TCP SYN scans.

Using '-sT' which is a TCP connect scan.

Using '-sN' which is a TCP null scan.

The option -sU tells nmap to perform a UDP scan, which is different from the default TCP scans.

Fill both blanks to create a dictionary comprehension that maps services to their port numbers if the port is less than 1024.

Cybersecurity

services = { [1]: [2] for [1], [2] in service_list if [2] < 1024 }

Drag options to blanks, or click blank then click option'

Aservice

Bport

Cservice_list

Dport_number

Attempts:

💡 Hint

Common Mistakes

Using 'service_list' as a key or value which is a list, not a single item.

Using 'port_number' which is not defined in the loop.

The comprehension uses service as the key and port as the value, iterating over service_list. The condition filters ports less than 1024.

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension that maps uppercase usernames to their IPs if the IP is not empty.

Cybersecurity

user_ips = { [1]: [2] for [3], [2] in user_data.items() if [2] != '' }

Drag options to blanks, or click blank then click option'

Ausername.upper()

Bip

Cusername

Duser_data

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'user_data' as a loop variable instead of the dictionary.

Not converting username to uppercase for the key.

Using the wrong variable names in the loop.

The comprehension maps username.upper() as the key to ip as the value, iterating over username and ip from user_data.items(). The condition filters out empty IPs.
