![]() ![]() Use this pragma in code modules that are exposed to potentially harmful data. For more information, see /GS (Buffer Security Check).Ĭompile by using /GS to enable strict_gs_check. By default, the /GS compiler option doesn't insert a cookie for all functions. Instructs the compiler to insert a random cookie in the function stack to help detect some categories of stack-based buffer overrun. With Hardware Assistent Bypass adapters, your device can act like a simple cable when there's a sofrware/hardware problem, when Sensei is shut down or even when the machine is powered off.This pragma provides enhanced security checking. Currently only Silicom Bypass Adapters are supported. This mode supports Hardware Assisted Bypass technologies. In this mode, it's not possible to make use of other existing OPNsense functionality like firewalling, VPN and other plug-ins since Sensei will bypass the Operating System and your device will act like a transparent filtering appliance. This experimental deployment mode allows you to be able to deploy Sensei like an Inline Web Secure Gateway. Bridge Mode (L2 Bridge Mode, Reporting + Blocking) With Emulated/Generic netmap driverĪs discussed above, if you suspect your Ethernet driver does not play well with netmap, you can use this option to be able to continue using Sensei with all of the functionality.īe noted that emulated driver is not as performant as the Native netmap driver. If you suspect that your ethernet drivers does not play well with netmap, than your best bet is using 元 mode with the Emulated/Generic netmap driver. Netmap can be picky when it comes to driver compatibility. With native netmap driverīeing the default deployment option, this option allows you to be able to make use of native netmap performance with regard to Ethernet drivers. This mode utilizes netmap(4), the underlying packet processing subsystem of the FreeBSD operating system. In this mode, you can both do reporting and enjoy all of the filtering functionalities of the software. Routed Mode is the option where you deploy Sensei on top of the firewall and you still make use of firewall's other services like 元/L4 filtering, routing, VPN and other plug-ins that are available. Routed Mode (元 Mode, Reporting + Blocking) If you're having trouble with the netmap subsystem and still want to make use of Sensei's advanced reporting capabilities, this is the best option.Ģ. ![]() In this mode, it's not possible to do blocking. Sensei grabs a copy of packets from the configured interfaces and provides you with a wealth of information through its reporting. Passive mode is like Suricata's IDS mode. See below for the detailed explanations for each of the deployment modes. If you don't know what you're doing or do not understand the stuff here, we suggest you leave it on the default option. Bridge Mode ( L2 Mode, Reporting and Blocking available)ĭefault mode is the second option: Routed (元 Mode) and with native netmap driver.Routed Mode ( 元 Mode, Reporting and Blocking available).Passive Mode ( Reporting only, no blocking).Sensei can be deployed in three different deployment modes: ![]()
