Scenario:

You are a cybersecurity analyst responsible for auditing user permissions and system vulnerabilities across multiple systems. Each system has a set of users with different permission levels and varying numbers of vulnerabilities that must be monitored.

Requirements:

$1.$ Define a list of tuples called systems. Each tuple should contain:

$-$ System name $($string$)$

$-$ A dictionary with the following key$-$value pairs:

$-$ 'users' $($a list of tuples where each tuple contains a username and a permission level: 'admin', 'user', or 'guest'$).$

$-$ 'vulnerabilities' $($a dictionary containing vulnerability categories as keys and the number of vulnerabilities as values$).$

Example:

systems $=[(\text{'}$System$1\text{'},\{\text{'}$users$\text{'}$: $[(\text{'}$alice$\text{'},$ 'admin'$),(\text{'}$bob$\text{'},$ 'user'$)],$ 'vulnerabilities': $\{\text{'}$critical$\text{'}$: $2,$ 'low':

$5\}\}),(\text{'}$System$2\text{'},\{\text{'}$users$\text{'}$: $[(\text{'}$charlie$\text{'},$ 'guest'$),(\text{'}$dave$\text{'},$ 'admin'$)],$ 'vulnerabilities': $\{\text{'}$high$\text{'}$: $3,$ 'medium': $2\}\})$

$2.$ Write a function audit$\_$permissions$($system$)$ that:

$-$ Takes a tuple system as a parameter.

$-$ Checks if any users have 'admin' permissions.

$-$ If no users have 'admin' access, print a warning: $\text{'}$No admin access on $[$system$\_$name$]\text{'}.$

$-$ Return a dictionary with system names as keys and permission audit results as values.

$3.$ Write a function check$\_$vulnerabilities$($system$)$ that:

$-$ Takes a tuple system as a parameter.

$-$ If the number of critical vulnerabilities is greater than $3,$ print: 'Critical vulnerabilities detected on $[$system$\_$name$].$ Immediate action required'.

$-$ If the total number of vulnerabilities exceeds $10,$ print a security risk warning.

$-$ Return a dictionary with system names and their vulnerability status $(\text{'}$secure$\text{'},\text{'}$at risk', or 'critical'$).$

$4.$ Write a function generate$\_$random$\_$vulnerability$\_$data$($systems$)$ that:

$-$ Randomly assigns users and permissions as well as vulnerability counts for each system.

$-$ To create a random number, you may use the random Python module. Import this module and

use its randint$()$ function to generate a random number. As an example, the following code

generates a random number between $1$ and $10$:

random$\_$number $=$ random.randint$(1,10)$

$5.$ Write a function get$\_$security$\_$summary$($systems$,$ permission$\_$status, vulnerability$\_$status$)$ that:

$-$ Outputs a summary report showing how many systems have 'secure' status, $\text{'}$at risk' status, or 'critical' status based on vulnerability check.

$-$ How many systems have no admin access.

$6.$ Implement a main$()$ function that:

$-$ Calls generate$\_$random$\_$vulnerability$\_$data$()$ to initialize system data.

$-$ Calls audit$\_$permissions$()$ and check$\_$vulnerabilities$()$ for each system.

$-$ Calls get$\_$security$\_$summary$()$ to display the overall security status.

Sample Run:

Initial system data:

$[(\text{'}$System$1\text{'},\{\text{'}$users$\text{'}$: $[(\text{'}$alice$\text{'},$ 'admin'$),(\text{'}$bob$\text{'},$ 'user'$)],$ 'vulnerabilities': $\{\text{'}$critical$\text{'}$: $2,$ 'low': $5\}\}),$

$(\text{'}$System$2\text{'},\{\text{'}$users$\text{'}$: $[(\text{'}$charlie$\text{'},$ 'guest'$),(\text{'}$dave$\text{'},$ 'admin'$)],$ 'vulnerabilities': $\{\text{'}$high$\text{'}$: $3,$ 'medium': $2\}\})]$

Generating random data for systems...

System$1$: Admin access found.

System$2$: No admin access on System$2.$

Critical vulnerabilities detected on System$2.$ Immediate action required.

Summary:

$1$ system with admin access, $1$ system without admin access.

$1$ secure system, $1$ system at critical risk.
