¿Qué es Security Service Edge (SSE)?

How Does SSE Work?

SSE works to protect data, detect threats, and control environment access. It integrates with existing security and cloud services, using cloud-native technologies to offer real-time visibility and control over user activities and data flows.

• Data Protection: SSE employs advanced security mechanisms like encryption, data loss prevention (DLP), and secure access controls to safeguard sensitive information both in transit and at rest.
• Threat Detection: SSE enables rapid response to incidents through use of real-time threat detection, powered by machine learning and artificial intelligence (AI), to identify anomalies and potential threats.
• Access Control: SSE enforces granular access controls based on user identity, device posture, and contextual factors, using a zero trust approach to minimize the attack surface.

The cloud-native technologies that SSE uses allow for scalability, provide consistent protection across various environments, and offer the flexibility to adapt.

¿Cuáles son los componentes principales de Security Service Edge?

Servicio de seguridad Edge está diseñado para converger la seguridad de la red en una única solución basada en la nube. Los componentes principales de SSE incluyen:

• Acceso a la red de confianza cero (ZTNA): ZTNA proporciona una alternativa superior a la red privada virtual (VPN) para un acceso remoto seguro a los recursos corporativos. ZTNA permite a las organizaciones implementar seguridad granular de confianza cero en la aplicación para el acceso remoto a aplicaciones corporativas que residen en las instalaciones o en la nube (p. ej. aplicaciones web internas, wikis, bases de datos, escritorios y servidores remotos, terminales SSH y entornos de producción en la nube).
• Puerta de enlace web segura (SWG): Los SWG están diseñados para proteger a los empleados de amenazas basadas en Internet y en la web, incluidos sitios de phishing, puntos de infección de malware y ransomware y clientes de bots de comando y control (C2). Un SWG supervisa y filtra el tráfico web para hacer cumplir las políticas de seguridad corporativas, bloquear el acceso a sitios que se sabe que no son correctos e impedir que los archivos maliciosos lleguen al sistema del usuario. Las capacidades clave de un SWG son el control de acceso, la protección de datos y la prevención de amenazas.
• Firewall como servicio de sucursal (FWaaS): Un firewall es la piedra angular de una política corporativa de seguridad roja, que permite a una organización restringir el acceso a la red y bloquear la entrada de archivos maliciosos a la red. Las ofertas de FWaaS brindan funcionalidad de firewall bajo un modelo basado en servicios, ofreciendo mayor flexibilidad y escalabilidad que las soluciones basadas en dispositivos. En el contexto de SSE, FWaaS se refiere a proteger sucursales, centros de datos y sitios remotos mediante seguridad de red basada en la nube. FWaaS se integra con soluciones SD-WAN para imponer una seguridad consistente en numerosos sitios y sucursales de forma automatizada.
• Agente de seguridad de acceso a la nube (CASB): A medida que las empresas se vuelven más dependientes de una variedad de aplicaciones de software como servicio (SaaS), necesitan soluciones que apliquen políticas de seguridad corporativas y controles de acceso a todos los servicios en la nube. Las soluciones CASB ayudan a gestionar el acceso y proteger los datos a los que se accede en la aplicación SaaS, con capacidades que incluyen autenticación, inicio de sesión único, autorización, cifrado, monitoreo y prevención de amenazas, entre otras.
• Identity and Access Management (IAM): IAM governs user identities and access to resources, enabling organizations to manage user identities, enforce authentication protocols, and implement role-based access controls.
• Data Loss Prevention: DLP mechanisms protect sensitive information from unauthorized access and exfiltration, monitoring data in motion, at rest, and in use, and applying policies to prevent data leaks.
