I have seen a lot of #pentesters struggle with tunneling and port-forwarding concepts. All #hackers should definitely understand these concepts for successful tests.

This thread is dedicated to Tunneling/PortForwarding tricks.

Local Port2Port

Open new Port in SSH Server --> Other port

ssh -R 0.0.0.0:10521:127.0.0.1:1521 user@10.0.0.1 #Local port 1521 accessible in port 10521 from everywhere

ssh -R 0.0.0.0:10521:10.0.0.1:1521 user@10.0.0.1 #Remote port 1521 accessible in port 10521 from everywhere

La info de ayer te desperto el bichito de meterte en #ciberseguridad? ¿Querés ser hacker? te cuento un poco de como arranque y algunos consejos para que logres progreso y te vayas enamorando. En el hilo anterior mencione aprender de sistemas operativos. Acá hay principalmente 2
Sé que estas pensando! sí! #Mac y #Windows, pero NO. Me refiero a #linux y a #windows. otro día hablamos de Mac. Es importante que conozcas a detalle como funcionan estos sistemas operativos. Para esto te podes bajar #virtualbox y crear dentro una virtual machine con un @ubuntu
y otra con #windows10 o el que tengas licencia. Hay que entender como funciona por dentro, cual es el tipo de file system que utiliza cada uno, porque se utilizan permisos, que tipo de archivos hay en cada directorio, que hacen esos archivos? cuales son ejecutables y cuales

Bir yazılım geliştiricinin bilmesi gerekenlerle ilgili 15 maddelik flood geliyor.. Mümkün olduğunca fazla keywordü bir araya toplamaya çalıştım.
Hadi Başlıyoruz!

1-Temel veri yapıları (linkedList, map, tree vb) ve temel algoritmalar (sıralama, arama vb)

Sıfırdan kodlama ihtiyacınız büyük ihtimalle hiç olmayacak. Ancak ihtiyaç anında doğru yerde doğrusunu seçebilmek için o veri yapısının veya algoritmanın nasıl çalıştığını bilmeniz şart
2- Network Temelleri

OSI Modelini ve 7 katmanı; temel protokolleri(#TCP-IP, TCP-UDP, #HTTP, #FTP), güvenlik protokollerini(#HTTPS, #SFTP, #SSL), monitoring protokolleri(#SNMP, ICMP) bilmekte fayda var. Ayrıca ağ ekipmanlarının görevlerini tanımak ve 7Layer yerlerini bilmek lazım

#prod365 #fr Les Plans de Continuité d'Activité (#PCA) ont pour but de retablir le SI après un "désastre". Un tel événement est aussi appelé "Disaster Recovery" (#DR) et inclus de nombreux événements graves, notamment la perte de #datacenter ou de données.
Citons quelques exemples: corruption silencieuse, destruction du medium de stockage (par erreur ou par nuisance: piratage ou rogue employee), isolation réseau (coup de pelleteuse dans la fibre), script d'administration mal fait / boucle foireuse, clause WHERE oubliée...
Pour de multiples raisons, certaines applications ne peuvent pas être disponibles en Actif/Actif, seulement Actif/Passif.
Cela implique de pouvoir répliquer les données live et de les réutiliser sur une autre machine.
