Enhancing SQL Injection Protection and Key Management

  • SQL injection protection can be enhanced using Application Firewall (WAF) rules, with a limit on the number of rules before incurring additional costs.
  • Third-party security services, like Fortinet's OS Top 10, can be subscribed to for additional rule sets in the marketplace.
  • Bot control features provide real-time visibility into bot activity, allowing users to manage what bots can access or block on their resources.
  • Specific IP addresses can be blocked or whitelisted through WAF rules, allowing access for trusted users like cloud support engineers.
  • Hardware Security Modules (HSM) securely store encryption keys in memory, ensuring keys are not written to disk, thus preventing theft.
  • HSMs follow the Federal Information Processing Standard (FIPS), with versions FIPS 140-2 Level 2 for multi-tenant and Level 3 for single-tenant compliance.
  • Key Management Service (KMS) simplifies the creation and control of encryption keys, using envelope encryption to protect data keys with master keys.
  • Users can create custom keys in KMS, with costs of $1 per key, while AWS-managed keys are free and automatically generated.
  • Cloud HSM is a single-tenant service that automates hardware provisioning and requires FIPS 140-2 Level 3 compliance, suitable for large enterprises.
  • AWS services utilize various initialisms, such as IAM for Identity and Access Management and S3 for Simple Storage Service, aiding in efficient communication and understanding.

Amazon Web Services Messaging and Email Solutions

  • Amazon SQS allows message queuing for up to 14 days, ensuring delivery at least once, and supports sequential or parallel message processing, ideal for delayed tasks like email queuing.
  • Amazon SNS is used for practical internal emails, sending notifications via multiple protocols, including HTTP and SMS, and is commonly triggered by events like server startups or budget alerts.
  • Amazon SES is designed for transactional emails triggered by in-app actions, such as sign-ups or password resets, and supports HTML emails, unlike SNS, which only sends plain text.
  • Amazon Pinpoint focuses on promotional emails, enabling email campaigns, contact segmentation, and A/B testing, and is distinct from SES, which is not recommended for promotional use.
  • Amazon WorkMail is a web client for managing company emails, similar to Gmail or Outlook, allowing users to create, read, and send emails through the AWS Management Console.
  • Amazon Inspector audits selected EC2 instances for security, generating detailed reports on security checks, while AWS Trusted Advisor provides a broader view of best practices across multiple services.
  • Elastic Load Balancer (ELB) includes four types: Application Load Balancer (ALB) for HTTP routing, Network Load Balancer (NLB) for high-performance TCP/UDP traffic, Gateway Load Balancer (GWLB) for third-party appliances, and Classic Load Balancer (CLB), which is being retired.
