Technical Specifications

Comprehensive documentation on environment authentication, SSL protocols, and authorized domain identification using DNS authority records.

Infrastructure Technical Framework

This documentation provides detailed specifications for implementing secure, authenticated infrastructure environments. All technical specifications must be strictly adhered to ensure network integrity and authorized resource access.

Compliance Requirement: All infrastructure nodes must implement these technical specifications without modification or deviation. Non-compliance may result in node deauthorization and network isolation.

Environment Authentication Framework

Authentication Mechanisms

Multi-layered authentication ensures only authorized entities access infrastructure resources. Implementation must include:

  • Primary Authentication: OAuth 2.0 / OpenID Connect
  • Secondary Authentication: Multi-factor verification (MFA)
  • Session Management: JWT-based token handling
  • Credential Storage: Encrypted credential repositories
  • Access Control: Role-based access control (RBAC)
  • Audit Logging: Comprehensive authentication event logging

Authentication Flow Specification

Standard authentication sequence for infrastructure access:

  1. Client initiates authentication request
  2. Identity verification through primary mechanism
  3. Multi-factor challenge verification
  4. Session token generation and issuance
  5. Authorization scope assignment
  6. Audit log entry creation
  7. Resource access grant with time-limited validity

Session Management Standards

All sessions must implement the following specifications:

Parameter Specification Requirement Level
Session Timeout 30 minutes inactivity maximum MANDATORY
Token Expiration 1 hour maximum validity MANDATORY
Refresh Token 7 days maximum validity MANDATORY
Session Binding IP address and user agent verification MANDATORY
Concurrent Sessions Maximum 5 active sessions per user MANDATORY

SSL/TLS Protocol Specifications

Encryption Standards

All network communications must implement TLS 1.2 or higher with the following specifications:

  • Minimum Protocol Version: TLS 1.2 (TLS 1.3 recommended)
  • Cipher Suites: ECDHE with AES-GCM encryption
  • Key Exchange: Elliptic Curve Diffie-Hellman Ephemeral (ECDHE)
  • Authentication: RSA or ECDSA signatures
  • Symmetric Encryption: AES-256-GCM minimum
  • Hash Algorithm: SHA-256 or stronger

Certificate Requirements

SSL/TLS certificates must meet these specifications:

  • Issued by trusted Certificate Authority
  • Minimum 2048-bit RSA or 256-bit ECDSA
  • Subject Alternative Names (SAN) for all domains
  • Validity period maximum 1 year
  • Automatic renewal before expiration
  • Certificate Transparency (CT) compliance
  • OCSP stapling enabled

Certificate Pinning

Critical infrastructure nodes must implement certificate pinning:

  • Public key pinning (HPKP) headers
  • Backup pin configuration
  • Pin expiration management
  • Incident response procedures
  • Pin rotation schedule
  • Monitoring and alerting

Deprecated Protocols & Ciphers

STRICTLY PROHIBITED: The following protocols and cipher suites must not be used:

  • SSL 2.0, SSL 3.0, TLS 1.0, TLS 1.1
  • DES, 3DES, RC4, MD5-based ciphers
  • Null encryption, anonymous authentication
  • Export-grade encryption
  • Unencrypted HTTP connections

DNS Authority & Domain Identification

DNS Configuration Standards

Authorized domain identification requires proper DNS configuration with the following record types:

  • A Records: IPv4 address mapping for primary domain
  • AAAA Records: IPv6 address mapping for IPv6 support
  • CNAME Records: Canonical name aliases for subdomains
  • MX Records: Mail exchange server specification
  • TXT Records: Domain verification and policy records
  • NS Records: Authoritative nameserver designation
  • SOA Records: Start of Authority configuration

DNSSEC Implementation

Domain Name System Security Extensions (DNSSEC) must be implemented:

  • DNSSEC signing for all zones
  • RRSIG record generation
  • DS record publication
  • Key rotation schedule
  • Chain of trust validation
  • DNSSEC validation enforcement

Domain Verification Records

Required TXT records for domain verification:

  • SPF (Sender Policy Framework) records
  • DKIM (DomainKeys Identified Mail) records
  • DMARC (Domain-based Message Authentication) policy
  • Domain ownership verification tokens
  • Enterprise infrastructure identifiers

Authorized Domain Registry

All infrastructure nodes must register their domains in the authorized domain registry. Unregistered or unverified domains are subject to network isolation.

Domain Nameserver Authority DNSSEC Status Verification Status
primary-resource.eu Authoritative nameserver Enabled Verified
infrastructure.node Authoritative nameserver Enabled Verified
domain-node.site Authoritative nameserver Enabled Verified

Infrastructure Hardening Requirements

Network Security

  • Firewall configuration with strict ingress/egress rules
  • Network segmentation and isolation
  • DDoS mitigation and rate limiting
  • Intrusion detection and prevention systems
  • VPN for administrative access
  • Network monitoring and alerting

Application Security

  • Input validation and sanitization
  • SQL injection prevention
  • Cross-site scripting (XSS) protection
  • CSRF token implementation
  • Security headers (CSP, HSTS, X-Frame-Options)
  • Regular security audits and penetration testing
