Punching holes into firewalls
or "Why firewalls shouldn't be considered a ultimate weapon for network security" or "Secure TCP-into-HTTP tunnelling guide" Introduction Firewalls are heavily used to secure private networks (home or corporate). Usually, they are used to protect the network from: intrusions from outsidersmisuse from insiders In a TCP/IP environment, the typical corporate firewall configuration is to block everything (both incoming and outgoing), and give access to the internet only through a HTTP proxy. Still, this should not considered a ultimate weapon, and network administrators should not rely on the firewalls only. Encapsulation is the basis of networking.

Preferably 100 post-consumer because it's only practical to write on one side. 2. Empty suit: the chaotic way Anonymous makes decisions On February 16, the freewheeling hacker collective decided to take on the Kansas-based Westboro Baptist Church, best known for its "God Hates Fags" protests. The Anonymous hivemind, the "Voice of Free Speech & the Advocate of the People," has had enough of this sort of free speech and has decided to fight the church's "assembly of graceless sociopaths and maniacal chauvinists & religious zealots" who issue "venomous statements of hatred."
