📘 Introduction

Welcome to the 90 Days of Cybersecurity challenge!
This repository provides a structured, 90-day self-paced study plan designed to help learners build a strong foundation in cybersecurity. Whether you're a beginner looking to break into the field or a professional aiming to sharpen your skills, this roadmap offers a wide range of curated resources, hands-on tasks, and learning materials.

The daily modules co and ad topics, including:

Networking fundamentals (Network+)

Security principles (Security+)

Linux basics and shell scripting

Python programming for security tasks

Traffic analysis and packet inspection

control with Git

SIEM tools and log analysis using the ELK stack

Cloud security with GCP, AWS and Azure

Penetration testing and ethical hacking

Landing the job: a one-page resume and an AI-assisted job-search pipeline with career-ops

Each day is designed with actionable tasks, tutorials, and reading materials to help you stay on track. For a full list of resources, refer to learn.md.

🎯 Goals and Audience

📌 Goals

The primary goal of this 90-day plan is to help learners:

Build a solid foundation in core cybersecurity concepts and practices.

Gain hands-on experience through daily exercises and real-world tools.

Develop the technical skills necessary for certifications such as CompTIA 网络+ and Security+.

Explore key domains including 网络 security, system hardening, cloud security, scripting, and ethical hacking.

Cultivate a consistent learning habit over 90 days to support long-term retention and growth.

By the end of this journey, you should feel confident na a of cybersecurity tools, concepts, and techniques.

👥 Intended Audience

This repository is ideal for:

Aspiring cybersecurity professionals preparing for entry-le or certifications.

IT professionals transitioning into a security-focused career.

Students studying computer science, information systems, or 网络 engineering.

Self-learners seeking a structured and comprehensi plan.

De and DevOps engineers looking to better understand secure infrastructure and threat detection.

Anyone curious about how cybersecurity works in real-world en.

No prior experience is required, though basic familiarity with computers, networks, or programming will be helpful.

🚀 Start Here

New to the plan? Read this first, then jump to Day 1.

Time budget: aim for 1-2 focused hours a day. The day numbers are a guide, not a deadline; it is fine to spend longer on a topic.

Follow the order: Days 1-28 (networking, security basics, Linux) are the foundation e else builds on. Do not skip ahead to hacking.

Certifications are optional: the 网络+ and Security+ playlists teach the concepts you need. You do not have to sit the exams to follow this plan or to get a first job.

Track your progress: fork this repo (or copy the plan into a notes file) and tick off each day as you finish it.

E is free: if a site puts content behind a paywall, use the alternati in the same section or in learn.md.

Questions or study buddies: use GitHub Discussions. Issues are for broken links and content fixes.

Day 93-95: Where and How to Apply

Search for jobs on Indeed:

Look for opportunities on LinkedIn:

Explore entry-le roles and career pathways on CyberSeek:

Run your job search with career-ops

career-ops is a free, open-源码 job-search system that runs inside an AI coding CLI such as Claude 代码, Codex, OpenCode, GitHub Copilot CLI or Antigravity CLI (free tier, no API key needed). Paste a job URL and it scores the posting against your cv.md (1-5), generates an ATS-friendly tailored PDF and tracks every application in one place. It ne for you; you always review and submit.

Before using any AI CLI, redact sensiti data in cv.md (for example address/phone) and review the 工具/provider’s privacy and data-retention settings before pasting your resume content.

1. Set up (Day 93): install Node.js, skim the setup guide, then run npx /career-ops init. Good security habit: npx downloads and runs the latest release, so check the release notes before running it (pin a with /career-ops@<> if you want a reproducible install). Open your AI CLI in the new career-ops folder and follow the onboarding chat. Tell it your target roles (for example *SOC analyst, security analyst, junior penetration tester*) so the e fit entry-le jobs.
2. E (Day 94): paste 10-20 postings you found on Indeed or LinkedIn. Only apply to roles that score 4.0/5 or higher; treat it as a filter, not a spray-and-pray 工具.
3. Apply and prepare (Day 95): generate tailored CVs for your shortlist, apply, and use the inter mode to build your STAR stories before the first call.
