Re: [ITCENTER] Re: cegah user bypass proxy
Pake Mikrotik Layer7 Filtering. Atau pake Content Filtering. Pertama, sniffing aja packetnya, lewat port berapa, lalu content communication TCP nya dilihat dan dicek untuk kemungkinan - kemungkinan bisa diblokir. Bicara mengenai FORTINET, iya nih .. saya juga ada terpasang disini, bypass proxy sih lewat. Katanya bisa deep packet inspection, jadi kalau usernya melakukan bypass proxy, itu akan percuma, tidak bisa. Cuma ya itu dia .. fakta di lapangannya masih tembus juga .. :)) - Rio.Martin - On 11/12/07, [EMAIL PROTECTED] [EMAIL PROTECTED] wrote: masih bisa tembus kok, dimari aja pake fortinet yang lumayan securitynya masih bisa kebobolan, kalo mau sich setiap log user nakal dicatet kalo ketahuan dengan buktinya kasih SP terus..sekarang software banyak portable jadi gak perlu instal contohnya kaya apps ultrasurf, dia hampir bisa nembus semua proxy n security tapi gak perlu instal.. pbgabsi [EMAIL PROTECTED] pbgabsi%40yahoo.com Sent by: ITCENTER@yahoogroups.com ITCENTER%40yahoogroups.com 11/11/2007 01:44 PM Please respond to ITCENTER@yahoogroups.com ITCENTER%40yahoogroups.com To ITCENTER@yahoogroups.com ITCENTER%40yahoogroups.com cc Subject [ITCENTER] Re: cegah user bypass proxy lah yg perlu dipertanyakan adalah user kok bisa install macam2 dan merubah setting?

--- pbgabsi [EMAIL PROTECTED] wrote: lah yg perlu dipertanyakan adalah user kok bisa install macam2 dan merubah setting? user - user tertentu ini diberikan hak admin. Pertimbangannya, ada satu problem ketika user printing dgn sebuah printer Xerox 8400 dan ketika melakukan pengubahan setting, spt, ukuran kertas, quality color, dll, user TIDAK BISA ketika memiliki privilege sebagai Limited User / user biasa. Baru bisa, ketika dgn privilege Administrator. Utk user yg pakai 3rd paty website kan bisa diblok dgn cara blok URL dan IP website tsb. Yach,... kalo ngeblok spt ini IPCOP saya bisa dan saya biasa melakukan. Tetapi ketika dikomputer user udah terinstall prg Tunnel / Open Proxy atau sejenisnya. Maka, jangankan cuma ngeblok URL / domain name, untuk blokir IP user bahkan MAC Address pun , tidak berpengaruh apa-apa. User masih TETAP BISA berinternet. Yang saya lakukan skr, blok port- port yg dipakai oleh progr ini. Walaupun kurang efektif tp cukup lumayan menghambat gerak user. --- In ITCENTER@yahoogroups.com, suroto sugeng [EMAIL PROTECTED] wrote: Hi, ...
