What's included

• Linux OS Security Hardening

  Implement security best practices for Linux servers, including user access controls, firewall configurations, and secure SSH settings; Enforce SELinux/AppArmor policies, PAM configurations, and sudo privilege management; Conduct kernel hardening, sysctl tuning, and disabling unnecessary services to minimize attack surfaces; Automate security configurations using Ansible, Bash scripts, or system policies.

• Cloud Security & Compliance Enforcement

  Implement AWS IAM, Azure RBAC, and security groups to ensure least privilege access; Configure cloud-native security tools (AWS Security Hub, Azure Defender, AWS GuardDuty, Azure Sentinel) for real-time threat detection; Define and enforce network security policies, including firewall rules, VPN access, and private networking; Secure cloud storage (AWS S3, Azure Blob) with encryption, access policies, and logging mechanisms.

• Vulnerability Assessment & Patch Management

  Conduct regular vulnerability scans on Linux systems; Automate patch management for RHEL, Ubuntu, and CentOS to mitigate security risks; Ensure compliance with CVE (Common Vulnerabilities and Exposures) patching guidelines; Maintain an effective change management and rollback strategy for security updates.

• Compliance with Industry Standards & Regulations

  Ensure Linux and cloud environments comply with ISO 27001, NIST, CIS Benchmarks, PCI-DSS, and GDPR; Implement audit logging and tracking for system and cloud security events using tools like Auditd, CloudTrail, and SIEM solutions; Conduct security assessments, penetration testing, and policy enforcement for regulatory compliance; Generate and maintain compliance reports and security documentation for audits.

• Incident Detection, Response, and Remediation

  Set up real-time security monitoring for Linux OS and cloud environments using tools like Wazuh, Osquery, and AWS Security Hub; Implement intrusion detection and prevention (IDS/IPS) for cloud and on-prem infrastructure; Develop incident response plans and forensic analysis processes for security breaches; Automate security incident response using scripts, SOAR (Security Orchestration, Automation, and Response) tools, or cloud-native remediation.

• Identity & Access Management (IAM) Security

  Implement centralized authentication and authorization using IPA (Identity Policy Audit), LDAP, and Kerberos for Linux environments; Configure MFA (Multi-Factor Authentication) and SSO (Single Sign-On) for cloud and on-prem users; Enforce IAM policies in AWS, Azure, and Linux environments to prevent unauthorized access; Automate user provisioning, deprovisioning, and role-based access control (RBAC) enforcement.

• Security Logging & Monitoring

  Configure log forwarding and alerting for real-time security analysis; Integrate Linux syslog, CloudWatch, and Security Event Logs for centralized monitoring; Implement custom security dashboards and reports for continuous monitoring and compliance tracking; Learn to deploy SIEM solutions (Splunk, ELK, Wazuh) to centralize security logs and detect threats;
