This chapter covers Security Hardening prodcures for Opuntia systems. By default Opuntia is configured to allow easy access to the system for administration. But these settings were chosen to favor access over security concerns. Opuntia does not come with an insecure configuration; but it allows access to login prompts in several situations that administrators should consider limiting access in higher security configurations.
When possible, administrators should consider sperating the control plane of your network from the data plane.
Hardening Web GUI¶
By default Opuntia allows access to the Web GUI on ANY IPv4/IPv6 interface address. We recommend excluding access to the Web GUI to the default Wan Firewall zone. Please see the Limiting External access chapter for more information.
Hardening SSH Access¶
By default Opuntia will respond to Ssh connection atempts to any bound IPv4/IPv6 address. We recommend excluding access to Ssh from the default Wan Firewall zone. Please see the Limiting External access chapter for more information.
Hardening Serial / Local Console¶
This requires Opuntia version 4.8.16 r49304 or newer.
By default Opuntia does not require a password when accessing system from a Serial or Local console. Since this requires physical access to hardware platforms this is generally considered safe. But Virtual Machines running Opuntia often do have remote methods to access the Local console. So this is an important security concern.
To require a password for Serial / Local Console logins use the following prodcure.
To make these adjustments use the following commands from the CLI
uci set system.@system.ttylogin="1" uci commit system service system restart
