ConceptsSince I’m about to describe how to roll your own router, it will help if you understand how most TCP/IP routing works. Any router, whether Cisco, Proteon, or Linux, is based upon the premise that packets need to be forwarded. Why? Because, presumably, the packets that come in on one interface are not local to the other interfaces in the router. Therefore, the router in question must be able to take a packet, look at its destination, and forward it to the appropriate interface.
How does the router map network destinations to interfaces? Well, just as every router needs to be able to forward packets, so too it needs the ability to consult, build, and update a lookup table, called a routing table, that maps destination networks to interfaces. If a packet comes in for network X, the routing table is consulted and the packet is dumped to the appropriate interface -- a local node that is either another gateway or the packet’s final destination. If network X does not exist in the routing table, the packet is dumped to the default destination, also denoted by IP address 0.0.0.0. If you have not specified a default destination, the packet is dropped, and an ICMP "Destination Unreachable" message is sent back to the originating network client.
Information covering the removal of boot sector viruses from the hard drive. 
The process needed to remove this type of virus from hard drive and memory is as follows:
NOTE: The instructions below are for Windows 95, 98 and ME. Users of NT, 2K and XP should not reboot their machine and should consult their anti-virus vendor for case-by-case support. The process below will not remove viruses from infected floppies, these must be scanned and disinfected after the memory and hard drive are clean.
* Boot the machine from a clean, write-protected floppy system diskette.
* This will take you to the DOS prompt (something like A:\> .)
* You now need to run your anti-virus scanner or disinfect manually.
Kata hacktivism adalah kombinasi dari hacking dan aktivisme. Hacktivist adalah seseorang yang menggunakan penetrasi sistem untuk menyebarkan pesam politik, sosial, atau pesan keagamaan. 
Sasaran orang-orang tersebut sebagian besar adalah server Web di mana banyak orang mungkin melihat pesan mereka.
Tingkat seperti hacktivist sering disebut sebagi Script Kiddie. Karena seluruh latihan ini dilakukan untuk mempromosikan pesan dan bukan untuk menyerang sistem, maka proses penetrasi itu sendiri bukanlah minat khusus ke hacktivist.
Ini berlaku untuk sebagian besar hacktivism. Akhir-akhir ini, khususnya dalam konflik antara Amerika Serikat dan Cina, hacktivism memperoleh wajah baru. Kelompok atau individu hacker mulai dari script kiddies dan cracker untuk Black Hats mulai menyerang dan mengotori situs Cina. Halaman Web organisasi politik di Afghanistan menjadi target selama ratusan penyerang paska serangan teroris di World Trade Center dan Pentagon di September, 2001.
The latest version of Microsoft's Internet Explorer browser contains a bug that can enable serious security attacks against websites that are otherwise safe.The flaw in IE 8 can be exploited to introduce XSS, or cross-site scripting, errors on webpages that are otherwise safe, according to two Register sources, who discussed the bug on the condition they not be identified. Microsoft was notified of the vulnerability a few months ago, they said.
Ironically, the flaw resides in a protection added by Microsoft developers to IE 8 that's designed to prevent XSS attacks against sites. The feature works by rewriting vulnerable pages using a technique known as output encoding so that harmful characters and values are replaced with safer ones. A Google spokesman confirmed there is a "significant flaw" in the IE 8 feature but declined to provide specifics.
