1. Foundation Building For Security
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:
- User and Permissions Management (e.g., SELinux, AppArmor).
- Auditing Tools: Auditd, Linux Security Modules (LSM).
- Secure File Systems: eCryptfs, EncFS.
- Practice:
- Implement CIS Benchmarks on Ubuntu/CentOS.
- Use audit Ctl to set up and monitor security rules.
Network Security
- Key Concepts:
- Firewalls (iptables, nftables).
- VPNs (WireGuard, OpenVPN).
- Network Monitoring: Wireshark, tcpdump, Zeek (formerly Bro).
3. Cloud and Container Security
Cloud Security
- Focus Areas:
- Identity and Access Management (IAM).
- Cloud Security Posture Management (CSPM).
- Key Management (AWS KMS, GCP KMS).
- Secure Virtual Networking (VPC, Firewall Rules).
- Hands-On:
- Set up secure workloads in AWS/GCP.
- Enable and monitor services like AWS GuardDuty or GCP Security Command Center.
Container Security
- Focus Areas:
- Image Scanning (Trivy, Clair).
- Runtime Security (Falco, Sysdig).
- Kubernetes Security (RBAC, Pod Security Policies).
- Practice:
- Harden Docker images and Kubernetes clusters using CIS Benchmarks.
- Deploy and test security tools in a Kubernetes lab.
4. Threat Modeling and Penetration Testing For Security
Threat Modeling
- Books:
- “Threat Modeling: Designing for Security” by Adam Shostack.
- Practice:
- Model threats for a real-world system using STRIDE or PASTA frameworks.
- Use tools like Microsoft Threat Modeling Tool or OWASP Threat Dragon.
Penetration Testing
- Learning Resources:
- “The Web Application Hacker’s Handbook” by Dafydd Stuttard.
- TryHackMe, Hack The Box, or PentesterLab for guided labs.
- Tools:
- Metasploit, Burp Suite, Nmap, and Nessus.
- Practice:
- Simulate attacks on a vulnerable VM (e.g., OWASP Juice Shop, DVWA).
