In sostanza, il livello di paranoia (PL) consente di definire quanto sia aggressivo il Core Rule Set.

wafparan01d3.py invia richieste malevole utilizzando payload codificati collocati in diverse parti delle richieste HTTP basate su parametri GET. I risultati della valutazione vengono registrati nel file di debug wafparan01d3.log creato sulla vostra macchina.mysql_gosecure.txt basati sulla ricerca "A Scientific Notation Bug in MySQL left AWS WAF Clients Vulnerable to SQL Injection" di gosecure disponibile qui https://www.gosecure.net/blog/2021/10/19/a-scientific-notation-bug-in-mysql-left-aws-waf-clients-vulnerable-to-sql-injection/ valutando i nostri WAF utilizzando modsecurity nei loro diversi livelli di paranoia sia in una configurazione predefinita che disabilitando diverse regole / IDs in modo scaglionato e rapido.
Pentesters: ambito GreyBox con accesso limitato alla macchina Linux del WAF utilizzando una "shell" con privilegi per avviare/ricaricare e modificare i file di configurazione di Apache del WAF in ambienti DEV/STG/TEST inviando diversi payload.Security Officers: prendere la migliore decisione per applicare il livello di paranoia del WAF per ogni soluzione della vostra organizzazione.Blueteamers: applicazione delle regole, migliori alert, meno falsi positivi nella vostra organizzazione.Integrators: eseguire una risoluzione dei problemi più approfondita e definire rapidamente il livello di paranoia del WAF adeguato personalizzando le regole o creando patch virtuali.Riferimento: https://www.inmotionhosting.com/support/server/apache/install-modsecurity-apache-module/
$ sudo apt update -y && sudo apt dist-upgrade -y
$ sudo apt-get install build-essential -y
$ sudo apt-get install apache2 -y

$ sudo apt-cache show libapache2-mod-security2
$ sudo cp /etc/modsecurity/modsecurity.conf-recommended /etc/modsecurity/modsecurity.conf
Successivamente, cambia la modalità di rilevamento di ModSecurity. Per prima cosa, spostati nella cartella cd /etc/modsecurity
2. Modifica il file di configurazione di ModSecurity con vi, vim, emacs o nano.
