Secure SDLC practices in Cybersecurity - Mini Project: Build & Apply

Understanding Secure SDLC Practices

📖 Scenario: You are part of a software development team that wants to build secure applications. To do this, you need to understand the Secure Software Development Life Cycle (SDLC) practices. These practices help keep software safe from hackers and bugs.

🎯 Goal: Build a simple checklist of Secure SDLC practices by creating a list of key steps, adding a priority level, selecting the most important steps, and finally summarizing the essential practices.

📋 What You'll Learn

Create a list of Secure SDLC steps with exact names

Add a priority level variable for security focus

Filter the list to include only high priority steps

Summarize the final list with a clear heading

💡 Why This Matters

🌍 Real World

Software developers and security teams use Secure SDLC practices to build safer software and reduce risks.

💼 Career

Understanding Secure SDLC is essential for roles like software developer, security analyst, and project manager to ensure security is integrated from the start.

1

Create the list of Secure SDLC steps

Create a list called sdlc_steps with these exact entries: 'Requirements Analysis', 'Design', 'Implementation', 'Testing', 'Deployment', 'Maintenance'.

Cybersecurity

# Create the list sdlc_steps with the exact steps
# Your code here

Need a hint?

Use square brackets to create a list and include all steps as strings.

2

Add a priority level for security focus

Create a variable called security_priority and set it to the string 'High'.

Cybersecurity

sdlc_steps = ['Requirements Analysis', 'Design', 'Implementation', 'Testing', 'Deployment', 'Maintenance']
# Create the variable security_priority and set it to 'High'
# Your code here

Need a hint?

Assign the string 'High' to the variable security_priority.

3

Select the most important Secure SDLC steps

Create a new list called high_priority_steps that includes only 'Requirements Analysis', 'Design', and 'Testing' from sdlc_steps.

Cybersecurity

sdlc_steps = ['Requirements Analysis', 'Design', 'Implementation', 'Testing', 'Deployment', 'Maintenance']
security_priority = 'High'
# Create high_priority_steps list with 'Requirements Analysis', 'Design', and 'Testing'
# Your code here

Need a hint?

Make a new list with only the three specified steps.

4

Summarize the essential Secure SDLC practices

Create a string variable called summary that says: 'Key Secure SDLC practices include Requirements Analysis, Design, and Testing.'

Cybersecurity

sdlc_steps = ['Requirements Analysis', 'Design', 'Implementation', 'Testing', 'Deployment', 'Maintenance']
security_priority = 'High'
high_priority_steps = ['Requirements Analysis', 'Design', 'Testing']
# Create the summary string with the exact text
# Your code here

Need a hint?

Assign the exact sentence to the variable summary.
