Network locality is not sufficient for deciding trust in a network.

10 Zero Trust is the new approach Key principles: The network is always assumed to be hostile. External and internal threats exist on the network at all times. Network locality is not sufficient for deciding trust in a network. Every device, user, and network flow is authenticated and authorized. Policies must be dynamic and calculated from as many sources of data as possible.

28 아카마이소개

29 Zero Trust At Akamai - WHY? We believe a network-centric approach to security and segregation is no longer sufficient to protect our company s assets o Firewalls and VPNs are great if you don t have any users We don t trust what we don t know We require more fine-grained access control NAC was great on paper, but was too difficult and expensive to implement We want to give our employees the same seamless and secure experience across any device from any location

30 The Internet As The Corporate Network Akamai has always believed that the Internet is THE network NO VPN

31 Akamai s Path to Zero Trust 2000 s Network and lication Controls Client Certificates for all Network dot1x - 2FA Federated Auth - SAML No internal wireless Bastion mgmt hosts Default no outbound internet Akamai on Akamai Launches lications externally available via Akamai on Akamai (AoA) internal IT hack (inbound proxy) Global Traffic Mgmt Site Shield No Passwords 2FA moves to cert+push MFA Passwords are largely eliminated from the environment 3rd party access (Soha) Akamai Enterprise Security Products Enterprise lication Access (EAA) replaces AoA IT hack Enterprise Threat Protector (DNS based threat intel) Akamai s 100 in 100 Challenge Zero Trust EAA (zero trust) client deployed successfully to hundreds of internal users Kona Site Defender (WAF) Bot Manager
