Security Breach / Issues

I have had an issue it appears in which someone has tried to hijack my WordPress account and has really cause me some great concern, in which the attachment will illustrate the failed attempts.

I received this morning the following message:

“40 failed login attempts (4 lockout(s)) from IP: 185.93.187.69

Last user attempted: luxor_admin

IP was blocked for 24 hours”

as part of my website i have a “user portal” in which users can create a user account.

Due to this email I am greatly concerned my website is under great threat and therefore would really like to seek your help / support.

I have applied a SSL Certificate as part of my website package in which I don’t know what this will do, but do you have any recommendations as to what I can do to ensure no more attacks take place on my website?

Thanks
