Containers have revolutionized application deployment, but they introduce unique security challenges that must be addressed.

Container Security Risks

Vulnerable base images
Secrets in images or environment variables
Privileged containers
Container escape vulnerabilities
Insecure container registries

Docker Security Best Practices

Use minimal base images (Alpine, distroless)
Scan images for vulnerabilities
Never run as root
Use read-only filesystems
Limit capabilities and resources
Sign and verify images

Kubernetes Security

RBAC: Implement role-based access control
Network Policies: Restrict pod communication
Pod Security: Use Pod Security Standards
Secrets Management: Use external secret stores
Admission Controllers: Enforce security policies

Security Tools

Trivy, Clair for image scanning
Falco for runtime security
OPA/Gatekeeper for policy enforcement

Penetration Testing Methodology and Benefits

Penetration testing simulates real-world attacks to identify vulnerabilities before malicious actors exploit them. Regular pentests are essential for validating security controls. Types of Penetration Tests Black Box: Tester has no prior knowledge, simulating external attacker. White Box: Full access to source code, architecture, credentials. Gray Box: Partial knowledge, simulating insider

Vulnerability Management Program Guide

A robust vulnerability management program is essential for identifying and remediating security weaknesses before attackers exploit them. Vulnerability Management Lifecycle 1. Discovery: Identify all assets in your environment 2. Assessment: Scan for vulnerabilities 3. Prioritization: Rank by risk and business impact 4. Remediation: Patch, mitigate, or accept risks 5. Verification:

Social Engineering Attack Prevention

Social engineering exploits human psychology rather than technical vulnerabilities. Understanding these attacks is crucial for building effective defenses. Common Social Engineering Tactics Pretexting: Creating a fabricated scenario to extract information. Baiting: Offering something enticing (infected USB drives, downloads). Quid Pro Quo: Offering a service in exchange for information. Tailgating: Following
