Cybersecurity Roadmap: Part 1 – A Step-by-Step Guide

CyberSecurity Roadmap

Introduction to Cybersecurity 

In today’s tech-driven landscape, cybersecurity has become essential rather than optional. As businesses and individuals increasingly depend on technology for storing, processing, and sharing information, the dangers posed by cyber threats have surged dramatically. Cybersecurity is all about protecting systems, networks, and data from unauthorized access, destruction, or theft.

With the rise of ransomware attacks, phishing scams, and data breaches, cybercriminals are continually adapting their methods. This reality underscores the importance for organizations of every size to take a proactive and strategic stance in safeguarding their digital resources. By cultivating a robust cybersecurity strategy, companies not only protect sensitive information but also foster customer trust and ensure smooth business operations.

1. Foundation Building For CyberSecurity

Cryptography and PKI

Books:

  • “Applied Cryptography” by Bruce Schneier.
  • “Cryptography and Network Security” by William Stallings.

Key Topics:

  • Symmetric vs. Asymmetric Cryptography (AES, RSA, ECC).
  • Key Management and Distribution (HSMs, key rotation policies).
  • Certificates, PKI, and X.509 Standard.

Tools:

  • OpenSSL: Practice generating keys, and signing certificates.

This is the bash code:-

openssl genrsa -out private.key 2048
openssl req -new -x509 -key private.key-out cert.pem -days 365
  • Explore AWS Key Management Service (KMS) or Google Cloud KMS.

2. System and Network Security

Linux Security

  • Topics:
  1. User and Permissions Management (e.g., SELinux, AppArmor).
  2. Auditing Tools: Auditd, Linux Security Modules (LSM).
  3. Secure File Systems: eCryptfs, EncFS.
  • Practice:
  1. Implement CIS Benchmarks on Ubuntu/CentOS.
  2. Use audit Ctl to set up and monitor security rules.

Network Security

  • Key Concepts:
  1. Firewalls (iptables, nftables).
  2. VPNs (WireGuard, OpenVPN).
  3. Network Monitoring: Wireshark, tcpdump, Zeek (formerly Bro).

3. Cloud and Container Security

Cloud Security

  • Focus Areas:
  1. Identity and Access Management (IAM).
  2. Cloud Security Posture Management (CSPM).
  3. Key Management (AWS KMS, GCP KMS).
  4. Secure Virtual Networking (VPC, Firewall Rules).
  • Hands-On:
  1. Set up secure workloads in AWS/GCP.
  2. Enable and monitor services like AWS GuardDuty or GCP Security Command Center.

Container Security

  • Focus Areas:
  1. Image Scanning (Trivy, Clair).
  2. Runtime Security (Falco, Sysdig).
  3. Kubernetes Security (RBAC, Pod Security Policies).
  • Practice:
  1. Harden Docker images and Kubernetes clusters using CIS Benchmarks.
  2. Deploy and test security tools in a Kubernetes lab.

4. Threat Modeling and Penetration Testing For Security

Threat Modeling

  • Books:
  1. “Threat Modeling: Designing for Security” by Adam Shostack.
  • Practice:
  1. Model threats for a real-world system using STRIDE or PASTA frameworks.
  2. Use tools like Microsoft Threat Modeling Tool or OWASP Threat Dragon.

Penetration Testing

  • Learning Resources:
  1. “The Web Application Hacker’s Handbook” by Dafydd Stuttard.
  2. TryHackMe, Hack The Box, or PentesterLab for guided labs.
  • Tools:
  1. Metasploit, Burp Suite, Nmap, and Nessus.
  • Practice:
  1. Simulate attacks on a vulnerable VM (e.g., OWASP Juice Shop, DVWA).

5. Governance, Risk, and Compliance (GRC)

Frameworks and Standards

  • Learn about:
  1. NIST Cybersecurity Framework (CSF).
  2. ISO 27001 Information Security Management.
  3. CIS Controls.
  • Study compliance requirements:
  1. PCI DSS, GDPR, HIPAA (based on industry focus).

6. Advanced Topics

Application Security

  • Key Areas:
  1. Secure coding practices (OWASP Top 10, SANS CWE Top 25).
  2. Application Security Testing (SAST, DAST).
  • Practice:
  1. Use tools like SonarQube, ZAP Proxy, or Snyk to analyze vulnerabilities.

Incident Response and Forensics

  • Key Skills:
  1. Log Analysis (Splunk, ELK Stack).
  2. Forensic Tools: Volatility, Autopsy.
  • Practice:
  1. Conduct mock incident response drills.
  2. Analyze memory dumps and disk images.

7. Practical Labs and Real-World Projects

Set Up a Secure Test Environment

  • Virtual Machines: Use VirtualBox or VMware for isolated environments.
  • AWS/GCP Labs:
  1. Set up cloud-based systems and secure them.
  • Codelabs:
  1. Use Google Codelabs or AWS Workshops to learn specific topics.

Simulate Attacks and Defenses

  • Create Red Team (offensive) and Blue Team (defensive) scenarios.
  • Deploy Honeypots (Cowrie, Dionaea) to observe attack patterns.

8. Certifications for Validation

  • Beginner:
  1. CompTIA Security+.
  2. AWS Certified Security – Specialty.
  • Intermediate:
  1. Certified Ethical Hacker (CEH).
  2. GIAC Security Essentials (GSEC).
  • Advanced:
  1. Offensive Security Certified Professional (OSCP).
  2. CISSP (Certified Information Systems Security Professional).

9. Community Engagement

  1. Join cybersecurity communities like OWASP, ISACA, or DEF CON.
  2. Contribute to open-source security tools or write blogs about what you are learning.
