Chapter 35: Careers, certifications and bug bounty — practice tasks

Open chapter lessons · Full guided lab: mock interview 10 security basics record (not repeated here)

35.1 Read a bug bounty scope

EasyIT

Why: Out-of-scope tests can be illegal.

What: Open a public program page and list In/Out of scope (read only).

How:

  1. Write 3 in-scope assets.
  2. Write 3 out-of-scope items.
  3. Note rules on automated scanning.

Expected output: Clear In and Out lists.

Hint

See the linked scope lab. Do not scan yet.

Answer / how to check
  1. You did not scan anything.

35.2 Map skills to a job post

EasyBanking

Why: See what employers ask.

What: Pick one SOC/analyst JD and mark skills you have.

How:

  1. List required tools.
  2. Mark Have / Learning / Gap.

Expected output: A 10-row skills table.

Hint

Be honest.

Answer / how to check
  1. At least 2 Gap items with a learning plan.

35.3 Record a 2-minute mock answer

MediumHealthcare

Why: Clear speaking wins interviews.

What: Answer: How do you secure a new Linux server?

How:

  1. Use a phone voice memo.
  2. Cover: updates, SSH keys, firewall, users, logs.
  3. Listen and note filler words.

Expected output: Under 2 minutes, 5 points covered.

Hint

See the linked mock interview lab.

Answer / how to check
  1. You listed the 5 points you said.

Extended teaching notes

Why this lesson matters

Part 11 turns tool skills into professional defensive practice: web risks, cloud, SOC work, hardening, cryptography, Indian law and careers. Every example below stays inside systems you own or public teaching material.

Indian company (sample data)

Suppose we are a junior security engineer at an Infosys or TCS client project. You take this lesson's checklist, map it to three production services (for example a Spring Boot API, a Node.js portal and a Python job), and open tickets with evidence and owners.

Global practice

Follow public guidance from OWASP, CERT-In, CISA and cloud provider Well-Architected / security pillars. Cite them in reports.

Everyday analogy

A cricket team that only practises hitting but never fielding loses matches. Offence skills in a lab exist to improve fielding in real systems.

Apply across stacks

Wherever code appears, ask the same questions.

Java / Spring Boot

Parameterise queries, encode output, limit Actuator, patch dependencies.

.NET

EF Core parameters, HTTPS, Data Protection API, patch NuGet.

Node.js

helmet, parameterized SQL, npm audit, lockfiles.

Python

ORM, autoescape, pip-audit, Bandit.

Go / PHP / Ruby

Safe templates, prepared statements, govulncheck / composer audit / Brakeman.

nginx / Apache / Tomcat

Hide versions, TLS, least-open ports.

MySQL / PostgreSQL / MongoDB / Redis

No public ports, auth on, least-privilege users.

AWS / Azure / GCP

Roles not keys, private data stores, cloud logs on.

Defender worksheet

  1. Write a 5-line summary.
  2. Name one related public breach or advisory.
  3. Practise one safe command on a lab you own.
  4. Write the fix for a teammate.

Recap

  • Permission first.
  • Fix over spectacle.
  • Evidence in notes.

Defender's worksheet (do this today)

  1. Write the lesson title and date.
  2. List three owned systems where it applies.
  3. Run one safe lab check and paste evidence.
  4. Write a two-sentence fix for a teammate.
  5. Note one CERT-In or CISA advisory that relates (title + date).

Indian workplace (sample)

At a Wipro or LTIMindtree client SOC, turn this lesson into one playbook step with an owner and a due date.

Global practice

Compare your notes with OWASP, CIS Benchmarks or a cloud Well-Architected security question. Write the overlap in five lines.

Family test

Explain the risk and the fix without jargon. If a parent or sibling can repeat the warning, you are ready to teach juniors.

Common mistakes

  • Skipping permission.
  • Tool collecting without fixing.
  • Publishing lab screenshots that contain secrets.
  • Treating encoding as encryption.

Recap

  • Evidence, fix, owner, date.
  • Own lab only.

Key terms for this page

  • Control: a safeguard (patch, config, process).
  • Finding: a weakness with evidence.
  • Remediation: the fix and how you verified it.
  • Scope: systems you are allowed to touch.
  • Least privilege: only the access required for the task.
  • Defence in depth: several controls in layers.

Mini case study

Suppose we are a junior engineer at Zoho or Freshworks (sample data). A weekly review asks each person to present one control from their area. You pick a control from this lesson, show a before/after screenshot from a lab, and list the production ticket you would open. That habit builds both skill and credibility.
