Study Notes
Sophos Firewall Device Access Configuration
- Sophos Firewall access is configurable via multiple methods, primarily WebAdmin
- Default IP address is 172.16.16.16 (/24)
- Default port is 4444
- Connection URL: https://<DeviceIP>:4444
- Firewall default administrator username is admin
- Firewall default administrator password is set during initial setup
Administrative Access Security
- Default settings allow LAN zone users to access WebAdmin and SSH logins
- To secure, disable zone-based access to admin services; implement ACLs (Access Control Lists) to allow access to specific network segments via local service ACL exception rules
- Disable unnecessary services in zones to improve security
CAPTCHA Configuration
- CAPTCHA is used on login pages for additional security (especially for WAN and VPN zones)
- Disabling CAPTCHA in the WAN zone is discouraged, as it reduces security against automated attacks
- CAPTCHA functionality can be enabled/disabled globally or for individual zones (WAN, VPN).
- Configuration is managed via console commands (e.g.,
system captcha-authentication-global [show|enable|disable])
Command Line Interface (CLI) Access
- Sophos Firewall also has a CLI (command-line interface) accessible via SSH or console
- Default credentials: username: admin, password: admin (can be changed on initial setup)
- Console parameters include baud rate (38,400), data bits (8), stop bits (1), and no parity/flow control
- CLI is useful for modifying the device’s IP
- SSH access can be configured using public key authentication
Zone-Based Access Control Lists (ACLs)
-
Device access allows defining services permitted within specific zones
-
Admin services (administrative access to the Sophos firewall)
-
Authentication services (client authentication)
-
Networking services (client to firewall, DNS)
-
Other services: wireless, VPN, user portal, routing, proxy, mail, SNMP.
Local Service ACL Exceptions
- Device access permits rules for local service ACL exceptions (allowing/blocking services for specified hosts)
- Rules are ordered, with later rules overriding previous ones
- Rules can be applied to either IPv4 or IPv6 (separate rules needed for both if required).
Additional notes about the documents
