Skyhigh client proxy

The Skyhigh Security Client Proxy software is a unified client that directs traffic to Skyhigh’s security solutions, such as Skyhigh Private Access, Cloud Firewall, and Secure Web Gateway (SWG). It helps safeguard your endpoint users from security threats when accessing the web, whether they are inside or outside your network.The Skyhigh Client Proxy is responsible for redirecting traffic from endpoints to the Skyhigh Security Service Edge (SSE) solution, which can be deployed both on-premises and in the cloud. Using policies configured through its policy engine, the Skyhigh Client Proxy intercepts and redirects various types of traffic to the different SSE services based on the license subscription.SCP & Secure Web Gateway - Hybrid SolutionClient Proxy is an essential component of the Skyhigh Security Web Protection hybrid solution. It works with the Cloud as well as the On-Prem instances of the SWG. This solution allows you to integrate the network-based and cloud-based security functions provided by Skyhigh Security Web Gateway and Skyhigh Security Web Security Gateway Service (Skyhigh Security WGCS), respectively.The Client Proxy software allows or redirects web traffic depending on the location of the endpoint: Endpoints located inside the network or connected by VPN — Traffic is allowed to continue to a Web Gateway appliance installed on the network for filtering. Endpoints located outside the network — Traffic is redirected to SWG for filtering.SCP & Skyhigh Private AccessThe Client Proxy enables Skyhigh Private Access to establish secure access to corporate applications from any device and location. The solution integrates with other Skyhigh SSE products to offer unified visibility, granular access control, and end-to-end data protection through a unified Cloud Management console. Additionally, the client acts as an enabler for the in-house DLP and RBI functionalities, to which the Private Access solution is integrated as well.SCP & Skyhigh Cloud FirewallThe Skyhigh Client

Proxy software is compatible with the Skyhigh Cloud Firewall, providing enhanced multi-layered protection and the capability for deep packet inspection. This combination offers organizations improved visibility, granular policy enforcement, and greater control over applications to defend against web-based threats.The Skyhigh Client Proxy redirects traffic to the Cloud Firewall based on the configured policies, effectively managing both HTTP and non-HTTP traffic. The integration of Client Proxy policies with Cloud Firewall policies facilitates traffic redirection for thorough inspection.Additionally, the Skyhigh SSE agent threat module works in conjunction with the Skyhigh Anti-virus and Sandboxing Engine to ensure complete protection for end-point devices, while also maintaining secure connectivity to the Skyhigh SSE network.Integration with Endpoint SecurityWhen deploying Client Proxy with Trellix Endpoint Security on the endpoints, you install and manage each product separately using Trellix ePO SaaS or Trellix ePO Cloud. Client Proxy administrators — Configure policies and run tasks as usual. Endpoint Security administrators — Have the option of configuring Trellix Endpoint Security Web Control so that it is disabled while Client Proxy is installed and actively redirecting web traffic.On endpoints running Windows, you can view whether Client Proxy is installed and running on the endpoint and actively redirecting traffic by opening the About Skyhigh Client Proxy window from the Start menu.

OverviewThis topic outlines the traffic flow between the endpoint client (Skyhigh Client Proxy) and both the Secure Web Gateway (SWG) and the Skyhigh Cloud Firewall. To access the Skyhigh Secure Service Edge (SSE) solution, we utilize a unified client known as the Skyhigh Client Proxy, also referred to as SCP. SCP enables users on Windows and macOS systems to connect and access both Web Gateway services and Cloud Firewall services. For details about SCP configurations (specifically for Cloud Firewall), see Client Proxy Set up For the First Time.The Skyhigh Secure Web Gateway is a cloud-based web security solution that provides protection against various threats that may arise when users from any organization accessing web services through cloud environments.Skyhigh Cloud Firewall is a cloud-based firewall solution converged with Skyhigh Security Service Edge to aggregate traffic from various sources that employ differing security postures. Skyhigh Cloud Firewall offers a multi-layered protection and performs deep packet inspection, allowing organizations with greater visibility, granular policy enforcement, and control over the applications to counter web-based threats.The Traffic Flow in Skyhigh Security Service EdgeSkyhigh Secure Web GatewayUse Case 1: The End User has a license for both Secure Web Gateway and Cloud FirewallIn this scenario, when the end-user attempts to access the web and generates HTTP/HTTPS traffic, below are the detailed steps that the traffic follows:: The Skyhigh Client Proxy installed on the end-user system encrypts the traffic and then sends it to the Cloud Firewall.NOTE: The traffic directed to the Cloud Firewall is subject to SCP policies, which may intercept and redirect it through the Secure Web Gateway as necessary. This traffic is encrypted and sent to the Cloud Firewall module through a Wireguard tunnel. The Cloud Firewall module decrypts the traffic and inspects it. It performs Deep Packet Inspection on the packet header. After inspecting the header, the Cloud Firewall module identifies the traffic as web traffic and redirects it to the Secure Web Gateway module The Secure Web Gateway module does the rest and sends the traffic to the intended destination.Use Case 2: The End User has a license for only Secure Web Gateway and NOT for Cloud FirewallIn this scenario, whenever the end-user tries to access the web and generates HTTP/HTTPs traffic, the Skyhigh Client Proxy simply forwards the traffic to the Secure Web Gateway module and the SWG module does the rest. Note that there is no involvement of the Cloud Firewall.Skyhigh Cloud FirewallWhenever the end-user generates Non HTTP/HTTPs traffic, The Skyhigh Client Proxy encrypts the traffic and forwards it to the Cloud Firewall through a tunnel. Upon receiving the packet, the Cloud Firewall decrypts it and begins inspection, focusing initially on the packet header only. After inspecting the packet header,

Oleh Jeff Ebeling - Arsitek Keamanan Cloud, Skyhigh Security 9 Juli 2024 4 Menit Baca Skyhigh Client Proxy (SCP) adalah alat yang sangat berharga yang tersedia untuk semua pelanggan Skyhigh Secure Web Gateway (SWG). Alat ini digunakan untuk mengautentikasi dan mengarahkan lalu lintas HTTP/S secara transparan ke Skyhigh Secure Web Gateways (SWG On Prem dan/atau SWG Cloud). Selain mengidentifikasi pengguna yang memanggil proses yang membuat permintaan web, SCP menyediakan konteks tambahan yang dapat digunakan untuk membuat pemfilteran proxy yang lebih cerdas dan keputusan koneksi! Lebih lanjut, seperti yang akan dijelaskan nanti di blog teknis ini, SCP dapat digunakan dan manfaatnya dapat direalisasikan terlepas dari di mana pun Skyhigh SWG berada dalam rantai proxy.Untuk memulai, silakan tinjau Panduan Produk SCP dan khususnya bagian yang menjelaskan konteks yang disediakan dalam header SCP(Metadata SCP). Header SCP yang disediakan meliputi:ID PelangganNama pengguna (dari login sistem)Grup (dari klien whoami)IP Tujuan AsliNama Proses (yang membuat permintaan pada klien)Proses Jalur EXEInformasi SistemAV Terinstal?Crowdstrike IDAV On?Skor Keseluruhan CrowdstrikeAV Terbaru?Skor OS CrowdstrikeFW Sehat?Konfigurasi Sensor Serangan KerumunanNama dan Versi OS KlienBahasa PenggunaWaktu setempatAlamat MAC KlienWaktu ProsesNama SistemPenandatangan ExeNama Kebijakan SCPNama Produk ExeID SCPHash MD5 ExeProfil Perangkat yang CocokCatatan lebih lanjut mengenai header SCP (header SWEB) akan diberikan nanti di blog ini.Jelas SCP bekerja dengan mulus dengan Skyhigh SWG, tetapi bagaimana jika Skyhigh SWG (Cloud atau On Prem) harus bertindak sebagai proxy induk untuk proxy pihak ketiga yang sudah digunakan di lingkungan, atau jika Skyhigh SWG hanya digunakan sebagai layanan pemfilteran yang dilampirkan ke proxy dekripsi pihak ketiga? Artikel ini menjelaskan

Beroperasi di "jaringan aman" yang tidak memiliki rute default dan/atau server DNS tidak menyelesaikan alamat eksternal. SCP menyediakan metode untuk mengautentikasi trafik yang tidak sadar akan proxy. Arsitektur ini menyediakan "jalan masuk" yang sederhana ke Skyhigh SSE yang memungkinkan fungsionalitas yang jauh lebih unggul daripada proxy lokal yang saat ini digunakan. Selain itu, SCP menambahkan opsi proxy transparan untuk Windows dan Mac untuk mencakup aplikasi yang tidak sadar proxy dan berjalan di lingkungan proxy eksplisit. Yang harus dilakukan oleh proxy anak adalah "lompatan berikutnya" lalu lintas SCP ke Skyhigh SWG (Cloud atau On Prem) dengan header SWEB yang dibiarkan utuh. Catatan Tambahan tentang Header SCP SWEBSCP menyediakan semua informasi kontekstual melalui header SWEB yang disisipkan ke dalam permintaan CONNECT untuk transaksi HTTPS atau permintaan metode individual untuk transaksi HTTP. Perintah dalam koneksi proxy HTTPS yang diterima TIDAK mendapatkan header. Ketika SWG memverifikasi header SWEB, SWG akan menghapusnya secara default (menonaktifkan penghapusan adalah bagian dari pengaturan otentikasi SWPS yang digunakan ketika mengevaluasi properti Authentication.Authenticate di Skyhigh SWG). Header SWEB yang dikodekan Base64 yang dihasilkan oleh SCP pertama-tama dienkripsi dengan rahasia bersama penyewa yang disertakan sebagai bagian dari kebijakan SCP yang dihasilkan di Skyhigh Cloud atau Trellix ePO. Penyewa diidentifikasi menggunakan header ID pelanggan SWEB. Proksi pihak ketiga tidak dapat mendekripsi header SWEB dan hanya dapat meneruskan header yang disediakan oleh SCP. Skyhigh SWG (ketika bertindak sebagai proxy yang mendekripsi) mempertahankan konteks SWG di seluruh koneksi HTTPS. Ketika menggunakan Next Hop Proxy ke cloud Skyhigh SWG dari Skyhigh SWG On Prem dengan
