CyberSecurity FAQ - What are the essential elements of cybersecurity architecture?

When specifying cybersecurity architectures it is useful distinguish among the following kinds of architectural elements:

Network Elements

• network nodes (computers, NICs, repeaters, hubs, bridges, switches, routers, modems, gateways, etc.)
• network communication protocols (TCP/IP, DHCP, DNS, FTP, HTTP, HTTPS, IMAP, etc.)
• network connections between nodes using specific protocols
• network topologies among nodes (point-to-point, bus, star, ring or circular, mesh, tree, daisy chain, hybrid)

Security Elements

• cybersecurity devices (firewalls, Intrusion Detection/Protection Systems [IDS/IPS], encryption/decryption devices, etc.)
• cybersecurity software (Anti-Virus (AV) software, spamware software, anti-malware software, etc.)
• secure network communication protocols (TCP/IP, DHCP, DNS, FTP, HTTP, HTTPS, IMAP, etc.)
• strong encryption techniques (end-to-end encryption, zero-knowledge privacy, blockchain, etc.)

Security Frameworks & Standards

• cybersecurity framework standards (NIST Risk Management Framework (RMF) SP 800-37, DoD Instruction 8510.01, ISO IEC 27000-Series)
• technology standards for cybersecurity software choices

Security Policies & Procedures

• security policies and procedures that are customized and enforced for your organization and/or project.
