Introduction to Security

In the world of DevSecOps, security is a priority from the beginning of development to continuous monitoring in production. With the increasing complexity of IT environments and the sophistication of cyber attacks, it is essential that developers, engineers, and operations teams work together to incorporate security practices at every stage of the software lifecycle. This space explores best practices, tools, and strategies to protect applications, data, and infrastructure, covering everything from secure development to incident response.

Secure Development​

  • Secure development practices: Secure Coding, code review, and rapid testing.
  • Security testing during CI|CD pipelines.
  • Use of containers and secure orchestration practices (Docker, Kubernetes).
  • Security practices when using Terraform, Ansible, and other IaC tools.

Vulnerabilities and Risk Management​

  • Vulnerability lifecycle: Identification, assessment, and mitigation.
  • Vulnerability management tools.
  • Patch management and system update practices.

Cyber Attacks​

  • DoS/DDoS attacks, Ransomware, Phishing, Man-in-the-Middle (MITM), Zero-Day exploits.
  • Mitigation strategies and proactive defense.
  • Implementation of security controls such as firewalls, WAFs (Web Application Firewalls), and intrusion detection and prevention systems (IDS/IPS).

Hardening and Infrastructure Security​

  • Reducing attack surface.
  • Hardening containers, images, and cloud infrastructure.
  • Security in Kubernetes environments.
  • Access control and network isolation.
  • VPN

Active Monitoring​

  • Static and dynamic code analysis tools.
  • Behavioral analysis tools.
  • Security observability: Using logs, traces, and metrics for security monitoring.
  • Best practices in configuring security alerts to detect anomalous activities.
  • Implementation of automated responses to security incidents.
  • Security auditing and penetration testing.

Encryption and Data Protection​

  • Encryption of data in transit and at rest.
  • Key management practices.
  • TLS, HTTPS, and digital certificates.

Incident Response and Disaster Recovery​

  • Procedures for rapid response to security incidents.
  • Disaster recovery plans (DRP) and business continuity (BCP).
  • Communication during incidents: Crisis management and transparency.

Secure Authentication and Authorization​

  • Implementation of OAuth, OpenID Connect, and SAML.
  • Role-based access control (RBAC) and attribute-based access control (ABAC).

Security Culture​

  • Prevention against social engineering attacks.
  • Adoption of security frameworks.
  • Compliance with regulations (e.g., GDPR, LGPD, CCPA).
