Alert message console

[Gordan_Grgurina]

Hi, today I logged on FG 100D, and alert message console showed a lot of login trials. Is this an attempt to break in the system and how to protect myself?

Hi, I suggest to set Trusted Hosts under the Admin configuration.

Yes it is (no surprise).

As best practice you should not allow admin access on a WAN port.

Instead, use a IPsec VPN and allow admin access on any internal port.

If you absolutely have to, set up Trusted Hosts as mentioned, or a Local-In policy restricting access to a narrow range of public IPs.

[Gordan_Grgurina]

Is it possible to set up a blockade to an IP address from which the login attempts unsuccessfully eg. 3 times in 1 minute for 1h?

[ede_pfau]

This is done automatically. I think the defaults are 5 failed attempts in a row (no time limit) and 1 hour of blocking the source address. These are parameters configurable in 'config system global' in the CLI.
