What are AWS Security & Compliance Services?

AWS provides the broadest and deepest set of security services of any cloud platform — 25+ dedicated security, identity, and compliance services designed to protect every layer of your cloud infrastructure. Unlike bolt-on security products, AWS security services are natively integrated — GuardDuty findings flow into Security Hub, CloudTrail logs feed Detective investigations, Config rules trigger automated remediation, and Macie discoveries enrich Security Lake analytics.

At the foundation is AWS IAM — the identity layer that controls who can access what, with fine-grained policies, role-based access, mandatory MFA, and Organizations-wide Service Control Policies (SCPs) that enforce security guardrails across hundreds of accounts. Amazon GuardDuty continuously monitors CloudTrail, VPC Flow Logs, and DNS queries using machine learning to detect credential compromise, cryptocurrency mining, data exfiltration, and communication with command-and-control servers. AWS Security Hub aggregates findings from all security services and continuously evaluates your environment against CIS, PCI-DSS, NIST, and AWS best practice benchmarks.

As an Authorized AWS Partner in India with ISO 27001 certification, PrecisionTech designs, deploys, and manages complete AWS security architectures — from IAM governance and threat detection to WAF/DDoS protection, encryption strategy, vulnerability management, and compliance automation for DPDPA 2023, RBI, SEBI, SOC 2, HIPAA, PCI-DSS, and ISO 27001.

VR
CISO, Digital Banking Platform — Mumbai
★★★★★

"After the DPDPA 2023 notification, we needed to map all personal data across 40+ S3 buckets and ensure data residency in India. PrecisionTech deployed Macie with custom Indian data identifiers for Aadhaar, PAN, and GSTIN — discovering 2.3 million documents containing personal data we didn't know about. They configured SCPs preventing any resource creation outside ap-south-1 and ap-south-2, implemented KMS encryption with automatic key rotation, and built a consent management workflow on DynamoDB. Our DPDPA readiness went from 30% to 95% in six weeks."

MS

Frequently Asked Questions — AWS Security & Compliance

Everything you need to know about AWS security services, compliance frameworks, threat detection, and how PrecisionTech secures cloud environments for businesses in India.

1 What is AWS Identity and Access Management (IAM) and why is it critical?

AWS IAM is the foundational security service that controls who can access what in your AWS environment. IAM lets you create users, groups, and roles with fine-grained permissions defined through JSON policies. Key capabilities: IAM Policies — JSON documents specifying Allow/Deny rules for specific API actions on specific resources. IAM Roles — temporary credentials for EC2 instances, Lambda functions, and cross-account access (no long-lived passwords). Identity Federation — integrate with Active Directory, Okta, or any SAML 2.0 / OIDC provider for single sign-on. IAM Access Analyzer — continuously analyzes policies to identify resources shared with external entities. Permission Boundaries — cap the maximum permissions a role can ever have, even if attached policies grant more. Service Control Policies (SCPs) — organization-wide guardrails that restrict what member accounts can do, regardless of their IAM policies. PrecisionTech implements least-privilege IAM architectures with mandatory MFA, role-based access, and Access Analyzer reviews for every AWS deployment.

2 How does Amazon GuardDuty detect threats in my AWS environment?

Amazon GuardDuty is an intelligent threat detection service that continuously monitors your AWS accounts and workloads for malicious activity. GuardDuty analyzes multiple data sources: CloudTrail Management Events — detects unusual API calls, unauthorized access attempts, and credential compromise. VPC Flow Logs — identifies port scanning, data exfiltration, communication with known malicious IPs, and cryptocurrency mining traffic patterns. DNS Logs — catches DNS-based data exfiltration and communication with command-and-control servers. EKS Audit Logs — detects suspicious Kubernetes API activity in Amazon EKS clusters. S3 Data Events — monitors S3 bucket access for anomalous data access patterns. Malware Protection — scans EBS volumes attached to EC2 instances and container workloads for malware. GuardDuty uses machine learning, anomaly detection, and integrated threat intelligence (AWS + CrowdStrike + Proofpoint) to generate findings rated Low, Medium, or High severity. PrecisionTech enables GuardDuty across all accounts via AWS Organizations with centralized finding aggregation in a delegated administrator account and automated remediation via EventBridge + Lambda.

3 What is AWS Security Hub and how does it centralize compliance?

AWS Security Hub is a centralized security posture management service that aggregates findings from GuardDuty, Inspector, Macie, IAM Access Analyzer, Firewall Manager, and third-party tools into a single dashboard with prioritized findings. Key capabilities: Automated Compliance Checks — Security Hub continuously evaluates your AWS resources against security standards: AWS Foundational Security Best Practices (FSBP) — 200+ checks across all major AWS services. CIS AWS Foundations Benchmark — Center for Internet Security hardening standards. PCI-DSS v3.2.1 — Payment Card Industry controls. NIST 800-53 — federal security controls framework. Security Score — each standard shows a percentage score representing how many controls pass. Cross-Account Aggregation — via Organizations, all member account findings flow to a central administrator. Automated Response — EventBridge rules trigger Lambda functions for auto-remediation (e.g., auto-encrypt unencrypted EBS volumes, close open security groups). PrecisionTech configures Security Hub with all four compliance standards enabled, cross-account aggregation, and custom auto-remediation playbooks tailored to Indian regulatory requirements.

4 How does AWS WAF protect web applications and what are managed rules?

AWS WAF (Web Application Firewall) protects web applications behind CloudFront, ALB, API Gateway, and AppSync from common web exploits. WAF inspects HTTP/S requests and allows, blocks, or rate-limits traffic based on configurable rules. Rule Types: IP-based rules (allow/block specific IP ranges), rate-based rules (throttle requests exceeding thresholds), string match rules (block requests containing SQL injection or XSS patterns), regex match rules, geo-match rules (block/allow by country), and size constraint rules. AWS Managed Rules — pre-built rule groups maintained by AWS: Core Rule Set (CRS) for OWASP Top 10, Known Bad Inputs, SQL injection, XSS, Linux/POSIX OS, PHP application, WordPress application, and Anonymous IP list. Bot Control — ML-powered bot detection that categorizes traffic as verified bots (Googlebot), self-identified bots, or targeted bots (scrapers, scalpers). Account Takeover Prevention (ATP) — inspects login requests for credential stuffing using stolen credential databases. Fraud Control — Account Creation Fraud Prevention (ACFP) — blocks fraudulent account registrations. PrecisionTech deploys WAF with layered rules: managed rule groups for baseline protection, custom rules for application-specific patterns, rate limiting for API endpoints, and Bot Control for high-value web properties.

5 What is the difference between AWS Shield Standard and AWS Shield Advanced?

AWS Shield Standard is automatic, free DDoS protection included with every AWS account. It protects against the most common Layer 3 (network) and Layer 4 (transport) DDoS attacks — SYN floods, UDP reflection, and other volumetric attacks — for all AWS resources including CloudFront, Route 53, ELB, and EC2. AWS Shield Advanced is a paid service providing enhanced DDoS protection with: Layer 7 (application) DDoS protection — detects and mitigates sophisticated HTTP flood attacks targeting your application logic. DDoS Response Team (DRT) — 24×7 access to AWS's DDoS experts who actively assist during an attack, writing custom WAF rules in real-time. Cost Protection — AWS credits your account for scaling charges incurred during a DDoS attack (EC2, ELB, CloudFront, Route 53 scaling costs). Advanced Monitoring — near real-time metrics, attack diagnostics, and historical attack reports. Health-based detection — uses Route 53 health checks to detect application-layer attacks more quickly. Automatic application-layer DDoS mitigation — automatically deploys WAF rate-based rules when a DDoS attack is detected. Shield Advanced is essential for internet-facing applications in regulated industries (banking, e-commerce, government) where downtime costs are high.

6 How does Amazon Inspector scan for vulnerabilities?

Amazon Inspector is an automated vulnerability management service that continuously scans AWS workloads for software vulnerabilities and unintended network exposure. Inspector supports three workload types: EC2 Instances — agentless scanning (via SSM Agent) that inventories installed software packages and compares against the CVE (Common Vulnerabilities and Exposures) database. Detects missing OS patches, vulnerable application libraries, and network reachability issues. ECR Container Images — scans container images in Amazon ECR for known CVEs in OS packages and programming language libraries (Java, Python, Node.js, Go, .NET, Ruby). Supports both initial scan and continuous re-scanning when new CVEs are published. Lambda Functions — scans Lambda function code packages and layers for vulnerable dependencies. Key features: Risk-based prioritization — Inspector calculates an Inspector Score (0–10) factoring in CVSS score, exploit availability, network exposure, and affected resource criticality. Software Bill of Materials (SBOM) — generates CycloneDX-format SBOMs exportable to S3. Integration — findings feed into Security Hub and EventBridge for centralized management and automated remediation. PrecisionTech enables Inspector across all accounts with automated ECR scanning in CI/CD pipelines and weekly vulnerability reports.

7 What is AWS CloudTrail and how does it support audit compliance?

AWS CloudTrail is the API audit logging service that records every API call made in your AWS account — who did what, when, from which IP address, and what was the result. CloudTrail is essential for security investigation, compliance auditing, and operational troubleshooting. Event Types: Management Events — control plane operations (CreateBucket, RunInstances, AttachRolePolicy) — enabled by default. Data Events — data plane operations (S3 GetObject/PutObject, Lambda Invoke, DynamoDB GetItem) — must be explicitly enabled. Insights Events — CloudTrail automatically detects unusual API activity patterns (e.g., sudden spike in TerminateInstances calls). CloudTrail Lake — a managed SQL-based query engine for analyzing CloudTrail events at scale. Query up to 7 years of events using SQL syntax without managing any infrastructure. Replaces the old pattern of shipping trails to S3 + querying with Athena. Organization Trail — a single trail that captures events across all accounts in your AWS Organization. Integrity Validation — CloudTrail generates SHA-256 hash digest files to cryptographically verify that log files have not been tampered with. PrecisionTech configures Organization-wide trails with CloudTrail Lake for SOC 2, DPDPA, and RBI audit requirements.

8 What is AWS Config and how do conformance packs work?

AWS Config is a service that continuously monitors and records your AWS resource configurations and evaluates them against desired settings. Config answers: "What does my environment look like right now?" and "Does it comply with my rules?" Config Rules — either AWS-managed rules (300+ pre-built) or custom rules (Lambda functions) that evaluate whether a resource configuration complies. Examples: s3-bucket-server-side-encryption-enabled, ec2-instance-no-public-ip, iam-user-mfa-enabled, rds-instance-deletion-protection-enabled. Conformance Packs — collections of Config rules and remediation actions packaged as a single unit. AWS provides pre-built packs for: Operational Best Practices for CIS, PCI-DSS, NIST 800-53, HIPAA, and AWS Well-Architected Security Pillar. You can also create custom packs for internal security standards. Remediation Actions — Config can automatically remediate non-compliant resources using SSM Automation documents. Aggregator — multi-account, multi-region aggregation for organization-wide compliance views. Configuration Timeline — view the complete change history of any resource over time. PrecisionTech deploys Config with organization-wide aggregation, PCI-DSS and CIS conformance packs, and auto-remediation for critical non-compliance findings.

9 What is Amazon Macie and how does it detect sensitive data in S3?

Amazon Macie is a data security service that uses machine learning and pattern matching to discover, classify, and protect sensitive data stored in Amazon S3. Macie automatically identifies: Personally Identifiable Information (PII) — names, addresses, Aadhaar numbers, PAN card numbers, passport numbers, phone numbers, email addresses, and dates of birth. Financial Data — credit card numbers, bank account numbers, and financial statements. Credentials & Secrets — AWS access keys, API keys, passwords, and private keys accidentally stored in S3. Healthcare Data — medical record numbers, health insurance IDs, and protected health information (PHI). Custom Data Identifiers — you can define custom regex patterns and keyword lists to detect organization-specific sensitive data (employee IDs, internal project codes, proprietary data formats). Macie also evaluates S3 bucket security posture: public accessibility, encryption status, shared access, and replication settings. Findings are published to Security Hub and EventBridge for centralized management. For DPDPA 2023 compliance, Macie is invaluable for discovering where personal data resides across your S3 data lake, enabling data mapping and consent management. PrecisionTech enables Macie organization-wide with custom Indian data identifiers (Aadhaar, PAN, GSTIN patterns).

10 How does AWS KMS manage encryption keys and what is envelope encryption?

AWS Key Management Service (KMS) is a managed service for creating, managing, and controlling cryptographic keys used to encrypt your data across 100+ AWS services. Key Types: AWS Managed Keys — automatically created and managed by AWS services (e.g., aws/s3, aws/rds). No management overhead. Customer Managed Keys (CMKs) — keys you create with full control over key policy, rotation, and lifecycle. Supports automatic annual rotation. Custom Key Stores (CloudHSM) — keys stored in FIPS 140-2 Level 3 validated Hardware Security Modules for maximum control. Envelope Encryption — the standard encryption pattern: KMS generates a data key → your application uses the data key to encrypt the actual data → KMS encrypts the data key itself with the CMK (master key). Only the encrypted data key is stored alongside the ciphertext. To decrypt: KMS decrypts the data key → application uses the plaintext data key to decrypt the data. This means your actual data never traverses KMS, and KMS only handles the small data key — enabling efficient encryption of large datasets. Key Policies + Grants — fine-grained access control over who can use keys for encrypt/decrypt/sign operations. Multi-Region Keys — replicate KMS keys across regions for disaster recovery and cross-region encryption. PrecisionTech enforces Customer Managed Keys with automatic rotation for all production workloads, with separate keys per environment (dev/staging/prod).

11 What is AWS Network Firewall and how does it differ from Security Groups and NACLs?

AWS Network Firewall is a managed, stateful network firewall service that provides fine-grained control over network traffic at the VPC level — going far beyond what Security Groups and NACLs offer. Comparison: Security Groups — instance-level, stateful, allow-only rules. Cannot inspect packet content, cannot do domain-based filtering, cannot log denied traffic natively. NACLs — subnet-level, stateless, allow/deny rules. No packet inspection, no domain filtering, basic IP/port rules only. AWS Network Firewall — VPC-level stateful inspection engine with: Stateful rules using 5-tuple (source IP, dest IP, source port, dest port, protocol) or Suricata-compatible IPS rules. Domain filtering — allow/deny traffic to specific domains (e.g., allow *.amazonaws.com, block everything else). TLS inspection — decrypt and inspect TLS-encrypted traffic for threats. IPS/IDS — Suricata-compatible intrusion prevention with AWS-managed threat intelligence rule groups (malware domains, botnets, emerging threats). Centralized management via AWS Firewall Manager across all VPCs and accounts. PrecisionTech deploys Network Firewall in a dedicated inspection VPC with Transit Gateway integration for centralized east-west and north-south traffic inspection.

12 What is Amazon Detective and how does it investigate security findings?

Amazon Detective is a security investigation service that uses machine learning, statistical analysis, and graph theory to help you quickly determine the root cause and scope of security findings from GuardDuty, Security Hub, and other sources. Detective automatically collects and processes log data from CloudTrail, VPC Flow Logs, EKS audit logs, and GuardDuty findings — building a unified behaviour graph that links all related activities across accounts, IP addresses, EC2 instances, IAM users/roles, and API calls over a rolling 12-month window. When investigating a GuardDuty finding (e.g., "unusual API call from compromised credentials"), Detective answers: What other API calls did this principal make? What resources were accessed? What IP addresses were involved? Was the volume of activity anomalous compared to the baseline? What was the geographic origin? Detective provides interactive visualizations — geolocation maps, API call volume timelines, resource interaction graphs, and finding group summaries that link related findings into a single investigation. PrecisionTech uses Detective as the primary investigation tool during security incident response, enabling our SOC analysts to trace the blast radius of a compromise within minutes rather than hours.

13 What is Amazon Security Lake and what is the OCSF format?

Amazon Security Lake is a purpose-built security data lake that automatically centralizes security data from AWS services, third-party sources, and custom applications into a single S3-based data lake using the Open Cybersecurity Schema Framework (OCSF). OCSF is an open-source schema standard (developed by AWS, Splunk, and other vendors) that normalizes security data from diverse sources into a common format — so you can query, correlate, and analyze events from GuardDuty, CloudTrail, VPC Flow Logs, Route 53 DNS logs, Security Hub findings, Okta, CrowdStrike, Palo Alto Networks, and other sources using a single query language. Key Benefits: Automatic data normalization — raw logs from 80+ sources are automatically converted to OCSF. Centralized storage — all security data in your S3 data lake with configurable retention (up to 7+ years for compliance). Query with any tool — Athena, OpenSearch, Splunk, or any tool that reads from S3/Parquet. Subscriber access — grant read access to third-party SIEM/SOAR tools without moving data. Multi-account, multi-region — Organizations-wide data collection. PrecisionTech deploys Security Lake for enterprises needing centralized security analytics — particularly for SOC 2 and DPDPA audit requirements where long-term log retention and correlation are mandatory.

14 How do I implement Zero Trust architecture on AWS?

Zero Trust on AWS follows the principle of "never trust, always verify" — every request is authenticated and authorized regardless of network location. AWS provides multiple building blocks: Identity Layer: IAM roles with least-privilege policies, MFA enforcement, IAM Identity Center (SSO) with short-lived credentials, STS AssumeRole for cross-account access, and IAM Access Analyzer to identify over-permissive policies. Network Layer: VPC with private subnets (no public IPs), VPC endpoints (PrivateLink) for AWS service access without internet traversal, AWS Network Firewall for deep packet inspection, and Security Groups as micro-segmentation. Application Layer: AWS WAF on all public endpoints, API Gateway with Cognito/Lambda authorizers, mutual TLS (mTLS) for service-to-service authentication, and AWS Verified Access for corporate application access without VPN. Data Layer: KMS encryption for data at rest, TLS 1.2+ for data in transit, S3 Block Public Access, and Macie for sensitive data discovery. Monitoring Layer: GuardDuty for threat detection, CloudTrail for audit, Config for compliance, Security Hub for centralized posture. PrecisionTech implements Zero Trust architectures using AWS Verified Access for remote workforce, PrivateLink for service access, and IAM Identity Center with mandatory MFA — eliminating the traditional VPN-based perimeter model.

15 How does AWS help with DPDPA 2023 (Digital Personal Data Protection Act) compliance?

The DPDPA 2023 is India's comprehensive data protection law governing how personal data is collected, stored, processed, and transferred. AWS services in India regions support DPDPA compliance through: Data Localisation: Deploy all services in Mumbai (ap-south-1) and Hyderabad (ap-south-2) — personal data never leaves India. SCPs can enforce that no resources are created outside India regions. Consent Management: Build consent tracking with DynamoDB or RDS — recording consent grants, withdrawals, and purpose limitations per data principal. Data Discovery & Classification: Amazon Macie identifies personal data (Aadhaar, PAN, names, addresses) across S3 buckets, enabling data mapping required by Section 5 (notice) and Section 6 (consent). Data Retention & Deletion: S3 Lifecycle Policies, RDS automated backups with defined retention, and DynamoDB TTL for automatic data expiry per DPDPA Section 8(7) — erase personal data when purpose is fulfilled. Access Control: IAM policies restrict who can access personal data. KMS encryption ensures data is unreadable without proper key access. Breach Notification: GuardDuty + Security Hub + EventBridge for automated detection and notification workflows to meet DPDPA Section 8(6) breach reporting requirements. PrecisionTech provides a DPDPA compliance accelerator — a pre-built architecture template, Config rules, IAM policies, and Macie configuration tailored for Indian businesses.

16 What RBI mandates apply to cloud security and how does AWS address them?

The Reserve Bank of India (RBI) has issued multiple circulars governing cloud adoption by regulated entities (banks, NBFCs, payment aggregators): RBI Data Localisation (2018) — all payment system data (full end-to-end transaction details, card data, customer data) must be stored exclusively in India. AWS India regions (Mumbai, Hyderabad) enable compliance. SCPs prevent data replication outside India. RBI Outsourcing Guidelines — require risk assessment, vendor due diligence, audit rights, and BCP/DR documentation for cloud providers. AWS provides compliance reports (SOC 1/2/3, ISO 27001) and contractual commitments. RBI Cybersecurity Framework (2016) — mandates SOC, VAPT, network segmentation, access controls, audit trails, and incident response. AWS services used: GuardDuty (SOC), Inspector (VAPT scanning), VPC/Network Firewall (segmentation), IAM (access control), CloudTrail (audit trails), and Security Hub (compliance dashboard). RBI Guidelines on IT Governance (2023) — emphasis on cloud security posture, configuration management, and continuous compliance. AWS Config with RBI-specific conformance packs, Security Hub FSBP standard, and automated remediation address these requirements. PrecisionTech has implemented AWS security architectures for multiple RBI-regulated entities — NBFCs, payment gateways, and cooperative banks — with full RBI compliance documentation.

17 How do I achieve SOC 2 compliance on AWS?

SOC 2 (System and Organization Controls 2) is an audit framework developed by AICPA that evaluates an organization's controls relevant to security, availability, processing integrity, confidentiality, and privacy. While AWS itself is SOC 2 certified (you can request AWS SOC 2 Type II reports via AWS Artifact), you are responsible for the controls you implement on AWS. SOC 2 control mapping on AWS: Security (CC6) — IAM least-privilege, MFA, Security Groups, KMS encryption, WAF, Shield, GuardDuty, Inspector. Availability (A1) — Multi-AZ deployments, Auto Scaling, Route 53 health checks, backup/restore testing, documented BCP/DR plan. Processing Integrity (PI1) — CloudTrail audit logging, Config rules for configuration compliance, Lambda-based data validation. Confidentiality (C1) — KMS encryption at rest and in transit, S3 Block Public Access, Macie for sensitive data detection, VPC endpoints for private connectivity. Privacy (P1–P8) — data mapping with Macie, consent tracking in application layer, data retention policies with S3 Lifecycle, access logs via CloudTrail. Evidence collection: AWS Config records, Security Hub compliance scores, CloudTrail logs, GuardDuty finding summaries, and Inspector scan reports serve as auditor evidence. PrecisionTech provides a SOC 2 readiness package — AWS architecture aligned to Trust Service Criteria, Config rules mapped to each control, and continuous compliance monitoring via Security Hub.

18 How does AWS support HIPAA compliance for healthcare workloads?

HIPAA (Health Insurance Portability and Accountability Act) governs the security and privacy of Protected Health Information (PHI). AWS supports HIPAA compliance through the AWS Business Associate Addendum (BAA) — a contractual agreement that makes AWS a Business Associate under HIPAA. HIPAA-Eligible Services: Over 100 AWS services are covered under the BAA, including EC2, RDS, Aurora, DynamoDB, S3, Lambda, ECS, EKS, GuardDuty, CloudTrail, KMS, and Security Hub. Technical Safeguards: Access Control — IAM with MFA, role-based access, and session policies limiting PHI access. Audit Controls — CloudTrail logs all API calls, VPC Flow Logs capture network activity. Integrity Controls — S3 Object Lock for immutable records, DynamoDB Streams for change tracking. Transmission Security — TLS 1.2+ enforced, VPN/Direct Connect for on-premises connections. Encryption — KMS encryption at rest for all storage services, with Customer Managed Keys for full key control. Minimum Necessary — IAM policies scoped to specific resources and actions required for each role. Physical Safeguards — AWS manages physical data center security (SOC 2 Type II certified). PrecisionTech deploys HIPAA-compliant architectures using only BAA-covered services, with encryption everywhere, comprehensive logging, and automated compliance checks via Config and Security Hub.

19 How does AWS security compare to Azure security and Google Cloud security?

All three major clouds offer comprehensive security services, but they differ in maturity, breadth, and Indian market relevance: Identity & Access: AWS IAM (most granular, policy-based) vs Azure Entra ID (strong enterprise AD integration) vs GCP IAM (resource hierarchy-based). AWS leads in fine-grained policy control and cross-account role assumption. Threat Detection: AWS GuardDuty (ML-based, multi-source) vs Azure Defender for Cloud vs GCP Security Command Center. GuardDuty offers the broadest data source integration and requires zero configuration. Compliance Automation: AWS Security Hub + Config (300+ managed rules, 4 compliance standards) vs Azure Policy + Defender vs GCP Security Health Analytics. AWS has the most mature conformance pack library. WAF/DDoS: AWS WAF + Shield (Advanced includes DRT team, cost protection) vs Azure Front Door + DDoS Protection vs GCP Cloud Armor. AWS Shield Advanced's cost protection is unique in the industry. India Regions: AWS has 2 India regions (Mumbai + Hyderabad, 6 AZs), Azure has 3 (Central, South, West India), GCP has 1 (Mumbai). For RBI data localisation, AWS and Azure both provide full coverage; GCP's single region limits DR options. Overall: AWS has the broadest security service portfolio (25+ dedicated security services) and longest track record. PrecisionTech recommends AWS for Indian enterprises needing comprehensive security with strong compliance automation.

20 What is AWS Firewall Manager and how does it centralize security policy management?

AWS Firewall Manager is a security management service that centrally configures and manages firewall rules and security policies across all accounts and resources in your AWS Organization. Firewall Manager supports: AWS WAF policies — deploy WAF rules across all ALBs, CloudFront distributions, and API Gateways organization-wide. New resources automatically inherit the WAF policy. Shield Advanced policies — enable Shield Advanced protection on specified resource types across all accounts. Security Group policies — audit and enforce Security Group rules. Detect and remediate overly permissive Security Groups (e.g., 0.0.0.0/0 inbound SSH). Network Firewall policies — deploy Network Firewall across VPCs organization-wide with centralized rule groups. Route 53 Resolver DNS Firewall policies — block DNS resolution of known malicious domains across all VPCs. Third-party firewall policies — manage Palo Alto Networks Cloud NGFW and Fortigate CNF deployments. Firewall Manager requires AWS Organizations and Config enabled in all accounts. It enforces policies automatically — when a new account joins the organization or a new VPC/ALB is created, the security policy is applied without manual intervention. PrecisionTech uses Firewall Manager as the central security policy engine for multi-account AWS environments, ensuring consistent WAF, Network Firewall, and Security Group policies across 50+ account Organizations.

21 What VAPT (Vulnerability Assessment and Penetration Testing) services does PrecisionTech provide for AWS?

PrecisionTech provides comprehensive VAPT services for AWS environments combining automated scanning with manual expert assessment: Automated Vulnerability Assessment: Amazon Inspector for continuous EC2, ECR, and Lambda vulnerability scanning. Security Hub FSBP and CIS benchmark compliance checks. Config rules for configuration drift detection. Third-party scanning tools (Qualys, Nessus) for deep network-level assessment. Manual Penetration Testing: AWS permits penetration testing on customer-owned resources (EC2, RDS, ECS, Lambda, API Gateway, etc.) without prior approval. PrecisionTech's certified security engineers perform: Network penetration testing — port scanning, service enumeration, exploit attempts against VPC resources. Web application penetration testing — OWASP Top 10 testing against applications behind ALB/CloudFront. API penetration testing — authentication bypass, injection, IDOR, rate limiting tests against API Gateway/ALB endpoints. Cloud configuration review — IAM policy analysis, S3 bucket exposure, Security Group audit, encryption verification, logging completeness. Social engineering assessment — phishing simulation targeting cloud console credentials. Deliverables: Detailed VAPT report with findings severity-rated (Critical/High/Medium/Low), proof-of-concept exploits, remediation recommendations, and executive summary. PrecisionTech conducts VAPT quarterly for compliance-driven clients (RBI, SEBI, SOC 2) and annually for others, with remediation validation re-testing included.

22 What is AWS Certificate Manager and how does it manage SSL/TLS certificates?

AWS Certificate Manager (ACM) provisions, manages, and deploys free public and private SSL/TLS certificates for use with AWS services. ACM handles the complexity of certificate lifecycle — issuance, renewal, and deployment — automatically. Public Certificates (Free): ACM issues Domain Validated (DV) certificates from the Amazon Trust Services CA at no cost. Certificates auto-renew before expiry (no more expired certificate outages). Supported on CloudFront, ALB, API Gateway, Elastic Beanstalk, and other integrated services. Private Certificates: ACM Private CA lets you create your own certificate authority hierarchy for internal services, IoT devices, and mTLS authentication. Key Features: Automatic renewal — ACM renews certificates 60 days before expiry without any manual intervention. Wildcard support — *.example.com certificates for all subdomains. Multi-domain (SAN) — one certificate covering multiple domain names. DNS validation — one-time CNAME record in Route 53 for automatic validation (no email approval needed). Integration — deploy to CloudFront + ALB with a single API call. PrecisionTech deploys ACM certificates on all production workloads — eliminating certificate expiry incidents and the cost of third-party CA certificates. We configure automated monitoring to alert if any certificate is not renewed within 30 days of expiry.

23 What is AWS Secrets Manager and how does it handle secrets rotation?

AWS Secrets Manager securely stores, retrieves, and automatically rotates secrets — database credentials, API keys, OAuth tokens, and other sensitive configuration values. Instead of hardcoding secrets in application code or config files, applications retrieve secrets at runtime via the Secrets Manager API. Key Capabilities: Automatic Rotation — Secrets Manager can rotate secrets on a schedule (e.g., every 30 days) using Lambda functions. Built-in rotation support for RDS MySQL, PostgreSQL, MariaDB, Oracle, SQL Server, Aurora, Redshift, and DocumentDB — no custom code needed. Fine-grained Access Control — IAM policies control who can read, write, or rotate specific secrets. Resource-based policies enable cross-account secret sharing. Encryption — all secrets encrypted at rest with KMS (AWS managed or customer managed keys). Versioning — Secrets Manager maintains previous versions during rotation (AWSCURRENT and AWSPREVIOUS stages), enabling rollback if rotation causes issues. VPC Endpoint — retrieve secrets without internet access via PrivateLink. Secrets Manager vs Parameter Store: Use Secrets Manager for secrets requiring automatic rotation and database credential management. Use Systems Manager Parameter Store for general-purpose configuration values and non-sensitive parameters. PrecisionTech mandates Secrets Manager for all database credentials, API keys, and third-party service tokens — eliminating hardcoded secrets from codebases.
