Step-by-step roadmap to enter the cybersecurity field in India — from networking basics to ethical hacking and incident response.
Complete the Foundation & Infrastructure Security branches before moving ahead.
Deep dive into OSI and TCP/IP models, network devices (routers, switches, firewalls), common protocols (ARP, ICMP, TCP, UDP, DNS, DHCP, HTTP/S), subnetting, network segmentation, packet analysis with Wireshark, network troubleshooting, and understanding their security implications and common attack vectors.
Mastering the Linux command line, file systems, user/group and privilege management (sudo), process management, understanding services (systemd), logging mechanisms (syslog, journald), package management, basic security hardening techniques, and bash scripting for security automation and administrative tasks.
Understanding Windows architecture, file systems (NTFS, permissions), user/group and privilege management, Active Directory basics (domains, forests, trusts), Group Policy Objects (GPOs) for security configurations, Event Viewer for security logging and analysis, PowerShell for administration and automation, and common Windows security hardening measures.
Core Python programming, network programming (sockets), file I/O, regular expressions, data parsing, interacting with APIs, and developing simple security tools like port scanners and log parsers.
Understanding virtualization technologies (VMware Workstation, VirtualBox, Hyper-V) and basic containerization (Docker) for isolated environments. Setting up a secure virtual lab, installing security-focused operating systems like Kali Linux, Parrot OS, and deploying vulnerable machines (e.g., Metasploitable, DVWA) for practical exploitation exercises.
Set up a virtual network with Linux and Windows servers. Configure basic firewall rules, secure SSH/RDP access, and implement basic log collection and analysis to identify potential anomalies.
Complete the Core Cybersecurity Concepts & Web Application Security branches before moving ahead.
In-depth study of the CIA Triad, Defense in Depth, Least Privilege, Separation of Duties, Threat Modeling (STRIDE), and an overview of common security frameworks like NIST Cybersecurity Framework and ISO 27001.
Understanding the difference between threats, vulnerabilities, and risks. Comprehensive study of CVSS scoring, using open-source (e.g., OpenVAS, Nmap scripting engine) and commercial (conceptual understanding of Nessus, Qualys) vulnerability scanners. Focus on interpreting scan results, vulnerability prioritization, remediation strategies, and patching best practices.
Comprehensive study of OWASP Top 10 vulnerabilities: SQL Injection, Cross-Site Scripting (XSS), Broken Authentication/Access Control, Insecure Deserialization, Security Misconfigurations, Server-Side Request Forgery (SSRF). Hands-on practice with Burp Suite.
In-depth exploration of symmetric (AES) and asymmetric (RSA, ECC) encryption, hashing functions (SHA-256, MD5 - and its weaknesses), digital signatures, Public Key Infrastructure (PKI) components and certificate management, the SSL/TLS handshake process, and common cryptographic attacks (e.g., brute-force, chosen-plaintext) and countermeasures.
Introduction to cloud computing models (IaaS, PaaS, SaaS), deployment models (public, private, hybrid), the shared responsibility model, common cloud security challenges, and basic security controls within major cloud providers like AWS (IAM, Security Groups, S3 security) and Azure (Azure AD, Network Security Groups).
Conduct a comprehensive penetration test on a deliberately vulnerable web application (e.g., OWASP Juice Shop or WebGoat). Identify, exploit, and document vulnerabilities, then write a detailed professional report including findings, impact, and precise remediation steps.
Complete the Ethical Hacking, Incident Response & Career Readiness branches before moving ahead.
Detailed exploration of penetration testing phases: Reconnaissance (OSINT, active scanning with Nmap, vulnerability scanning), Enumeration (SMB, DNS, SNMP), Gaining Access (exploitation of various services, brute-force attacks, phishing vectors), Post-Exploitation (meterpreter, C2 frameworks), Privilege Escalation (Linux/Windows techniques), Maintaining Access (backdoors, persistent shells), Covering Tracks (log manipulation), and professional report writing with executive summaries and technical findings.
In-depth understanding of various network security devices and controls: Next-Generation Firewalls (NGFWs), Intrusion Detection Systems (IDS), Intrusion Prevention Systems (IPS), Virtual Private Networks (VPNs - IPsec, SSL/TLS), Network Access Control (NAC) solutions, Data Loss Prevention (DLP), and Secure Web Gateways (SWG).
Understanding the role, tiers, and operations of a Security Operations Center (SOC). Conceptual overview and practical interaction with leading SIEM tools (Splunk, ELK Stack, Microsoft Sentinel), Security Orchestration, Automation, and Response (SOAR) platforms, Endpoint Detection and Response (EDR), and Extended Detection and Response (XDR). Focus on alert triage, advanced log analysis, threat intelligence integration, and practical threat hunting techniques.
Mastering the NIST Incident Response Lifecycle (Preparation, Detection & Analysis, Containment, Eradication, Recovery, Post-Incident Activity). Introduction to digital forensics, chain of custody, evidence collection, and basic forensic tools like Autopsy/FTK Imager.
Understanding security implications of containers (Docker) and orchestration (Kubernetes). Focus on secure image building, container runtime security, network segmentation in containerized environments, and integrating security practices into the CI/CD pipeline (DevSecOps principles: Shift Left security, security as code, SAST/DAST overview).
Understanding different types of malware (viruses, worms, trojans, ransomware), basic static and dynamic analysis techniques, sandboxing environments, and an introduction to reverse engineering concepts using disassemblers (e.g., Ghidra) and debuggers.
Overview of industry-recognized certifications (CompTIA Security+, CySA+, CEH, OSWP, CCNA Security, Azure/AWS Security), resume building, interview preparation strategies, and identifying niche career paths in the Indian cybersecurity landscape.
Strategies and tools for finding vulnerabilities in live applications, understanding leading bug bounty platforms (HackerOne, Bugcrowd), adhering to responsible disclosure principles, and writing effective bug bounty reports.
Respond to a simulated cyber attack scenario, executing a full incident response lifecycle. This involves detection, analysis of compromised systems (logs, memory, disk images), containment, eradication, recovery, and generation of a comprehensive incident report.
