    Gobuster

    Gobuster

    Directory/File, DNS and VHost busting tool written in Go

    Gobuster is a tool used to brute-force. This project is born out of the necessity to have something that didn't have a fat Java GUI (console FTW), something that did not do recursive brute force, something that allowed me to brute force folders and multiple extensions at once, something that compiled to native on multiple platforms, something that was faster than an interpreted script (such as Python), and something that didn't require a runtime. Provides several modes, like the classic directory brute-forcing mode, DNS subdomain brute-forcing mode, the mode that enumerates open S3 buckets and looks for existence and bucket listings, and the virtual host brute-forcing mode (not the same as DNS!). Since this tool is written in Go you need to install the Go language/compiler/etc. Full details of installation and set up can be found on the Go language website. Once installed you have two options. You need at least go 1.16.0 to compile gobuster.

    Fail2Ban

    Fail2Ban

    Daemon to ban hosts that cause multiple authentication errors

    Fail2Ban scans log files and bans IPs that show the malicious signs -- too many password failures, seeking for exploits, etc. Generally Fail2Ban is then used to update firewall rules to reject the IP addresses for a specified amount of time, although any arbitrary other action (e.g. sending an email) could also be configured. Out of the box Fail2Ban comes with filters for various services (apache, courier, ssh, etc). Fail2Ban is able to reduce the rate of incorrect authentications attempts however it cannot eliminate the risk that weak authentication presents. Configure services to use only two factor or public/private authentication mechanisms if you really want to protect services.

    jwt-auth

    jwt-auth

    JSON web token authentication for Laravel and Lumen

    jwt-auth provides a simple means of authentication within Laravel using JSON Web Tokens (spec). There are several ways to create a token within the package. There are simple ways to do it, and more advanced methods if you want greater control. The most common way to create a token would be to authenticate the user via their login credentials, and if successful return a token corresponding to that user. You can also skip user authentication and just pass in a User object. Once a user has logged in with their credentials, then the next step would be to make a subsequent request, with the token, to retrieve the users' details, so you can show them as being logged in. To make authenticated requests via http using the built in methods, you will need to set an authorization header. If you don't like the idea of catching mulitple exceptions inline, then you are free to add a global exception handler with Laravel.
