Key Components of Sophos Firewall Management

Getting Started: Initial Setup

Deployment Modes: Sophos Firewall supports several deployment modes, including gateway mode, bridge mode, and mixed mode. Choose the mode that fits your network architecture.

Basic Configuration: During the setup process, you'll configure essential settings like administrative access, network interfaces, zones, and basic firewall rules. This foundational setup ensures secure access and smooth traffic flow.

Firewall Rule Creation and Management A firewall is only as effective as the policies it enforces. With Sophos Firewall, creating and managing rules is intuitive but still requires careful planning.

Defining Policies: Sophos Firewall lets you define user, application, and network-based policies to allow or block traffic. These rules can be tailored based on zones, ports, services, and specific user groups.

Application Control: Sophos provides built-in application control features that allow administrators to block or throttle traffic from unwanted or high-bandwidth applications.

Web Filtering: Integrated web filtering policies enable you to block malicious or inappropriate websites by category or individual URLs, adding another layer of security.

Intrusion Prevention System (IPS) Sophos Firewall features a powerful Intrusion Prevention System (IPS) that analyzes traffic to detect and block suspicious activity in real time. You can configure IPS profiles based on the needs of different parts of the network.

Signature-Based Detection: Sophos regularly updates its threat signature database to identify known attacks.

Custom Profiles: Tailor IPS profiles to protect critical systems by adjusting sensitivity levels and selecting which types of traffic or vulnerabilities to focus on.

Deep Packet Inspection (DPI) Sophos Firewall leverages DPI to inspect traffic beyond traditional port and protocol filtering. DPI analyzes the content of packets, enabling detection of malware, vulnerabilities, and other hidden threats.

SSL/TLS Decryption: Sophos Firewall can decrypt encrypted web traffic (SSL/TLS), allowing DPI to scan for threats within secure sessions. You can also create exceptions for trusted sites.

Advanced Threat Protection (ATP) Sophos Firewall includes Advanced Threat Protection (ATP), a real-time detection and response system for identifying and neutralizing zero-day threats and advanced persistent threats
