Web Gateway Appliance

By: Charles Tajvidi

In eighty years a personal computer was commonly used as a sophisticated typewriter or a powerful worksheet. Rarely a computer was connected to a network or even to another computer and Internet was reserved just for few advanced users.

Today hundreds of millions of people worldwide connect regularly to Internet and Web applications hosted all over the world. The Web popularity has transformed a personal computer into a terminal machine connecting people.

For most of us Web applications are vital and Internet changed our life forever. Never before did humanity have such a powerful tool to share knowledge, information and emotion. Unfortunately and in despite of that so wonderful description, connecting to the Internet also means exposing yourself to serious threats.

In such a world wild web the main question is how to deliver Secure and Optimized Web traffics? Controlling Web accesses, securing Web applications, managing Web flows, filtering Web content, supporting overloads, managing the Quality of Service or providing High Availability are all issues that concern the nature of Web traffics that cannot be treated smoothly in the Web application itself nor at the network level.

Several approaches aim to offer solutions to manage Web traffics. Among all solutions, there are two that have attracted our attention. The first approach consists of integrating many Commercial Appliances to reach the goals. The second approach is based on the integration of Open Source technologies and sometimes, homemade solutions. While the first solution trusts on the know-how of reputed appliance manufacturers, the second solution trusts on the know-how of the Open Source community and the IT staff.

The lack of both considerations is that more often several technologies are to be integrated to provide both security and optimization. These approaches leverage the complexity of the final solution and as a result the maintenance costs.

The ideal solution would be an integrated off-the-shelf solution requiring no additional development and based on Open Source technologies to be flexible enough and trustworthy. CacheGuard provides such a solution with a new approach based on an Open Source Operating System Appliance (OSOSA). The product is proposed as software, hardware and virtual appliance.

CacheGuard differs from any other solution by being an integrated solution joining together numerous free Open Source technologies and proprietary Open Source developments to secure and optimize Web traffics at the same time. The OS Appliance approach allows to auto magically transform an x86-based machine into a powerful and highly integrated appliance that manages all main Web traffic issues in a unique box.

Install CacheGuard OS on your hardware box in less than 5 minutes and gain in transparency, flexibility and productivity. Download your free trial version at www.cacheguard.com.

Hillary Mendadak ke Baghdad

Sabtu, 25 April 2009 | 15:16 WIB

BAGHDAD, KOMPAS.com — Menteri Luar Negeri Amerika Serikat Hillary Clinton, Sabtu (25/4), tiba di Baghdad dalam kunjungan mendadak yang terjadi pada saat gelombang kekerasan melanda negara yang beberapa pekan lagi akan ditinggalkan tentara AS itu.

Hillary mendarat di ibu kota Irak sekitar pukul 08:30 waktu setempat, sehari setelah dua penyerang bunuh diri menewaskan 55 peziarah Syiah di suatu masjid di kota itu. Kunjungan tersebut juga terjadi lebih kurang 48 jam setelah serangan serupa menewaskan puluhan orang di bagian utara kota tersebut.

Hillary mengatakan, dia akan menganalisis situasi keamanan di tengah-tengah pengeboman-pengeboman yang menewaskan lebih dari 250 orang dalam bulan ini dan pada saat pasukan AS mulai ditarik mundur dari kota-kota besar dan kecil di seluruh negeri.

"Saya akan mengadakan pertemuan dengan Jenderal Ray Odiermo, dan saya juga ingin mendengarkan masukan dari tangan pertama," kata Hillary merujuk pada perwira senior militer AS di Irak itu. Ia juga mencatat serangan-serangan bunuh diri yang menelan banyak korban pada Kamis dan Jumat.

"Saya ingin mengevaluasi jenis-jenis dari penolakan upaya-upaya itu dan apa yang bisa dilakukan untuk mencegah mereka melakukan serangan terhadap Pemerintah AS dan pasukan AS," katanya kepada para wartawan yang bersamanya dari Kuwait.

Menlu Hillary dijadwalkan akan bertemu dengan Perdana Menteri Nuri al-Maliki, Presiden Jalal Talabani, pejabat-pejabat senior lain, dan perwakilan khusus Sekjen Perserikatan Bangsa Bangsa (PBB) untuk Irak, Staffan de Mistura.

Kedatangan Hillary terjadi beberapa jam setelah Duta Besar AS yang baru untuk Irak, Christopher Hill, mendarat di Baghdad untuk menempati posnya. "Kami ingin menunjukkan dan memperkuat keberlanjutan komitmen kita kepada rakyat Irak dan untuk stabilitas, keamanan, serta kemandirian Irak," kata Hillary mengenai kunjungan keempatnya ke Irak, tetapi untuk pertama kalinya sebagai Menlu.

Pemerintah Irak telah lama mencatat bahwa peningkatan serangan-serangan belakangan ini sangat disesalkan. Namun, serangan-serangan itu tidak bisa disejajarkan dengan aksi kerusuhan yang membawa negara ini ke kancah perang sipil pada tahun 2006.

"Pemboman-pemboman bunuh diri yang menelan banyak korban dan mengerikan dalam merenggut nyawa manusia dan mereka yang cedera merupakan cara yang tragis, suatu tanda bahwa para penolak (kepergian tentara AS) khawatir bahwa Irak sedang mengarah pada tujuan yang benar," katanya.

Pasukan AS akan ditarik dari kota-kota besar dan kecil di Irak pada akhir Juni, berdasarkan perjanjian yang ditandatangani antara Washington dan Baghdad pada November tahun lalu. Kunjungan Hillary juga terjadi dua pekan setelah Presiden Barack Obama berkunjung ke Baghdad, dan memperingatkan bahwa pada 18 bulan mendatang Irak akan memasuki masa kritis.

Pada Februari lalu, Obama mengumumkan strategi baru yang menginginkan sebagian besar pasukan tempurnya ditarik dari Irak pada Agustus 2010, meskipun sekitar 50.000 tentara masih akan berada di sana sampai akhir tahun berikutnya.

Aksi kekerasan telah turun tajam sejak kelompok Sahwa, yang kebanyakan bekas pemberontak Sunni, bersekutu dengan pasukan AS untuk melawan Al Qaeda pada akhir tahun 2006, ketika banyak tentara AS disebarkan di negara itu berdasarkan strategi mantan presiden George W Bush.

- Wah, Indonesia Pengutang Terbesar ADB

Kamis, 23 April 2009 | 09:56 WIB

JAKARTA, KOMPAS.com — Rupanya Indonesia adalah debitor (peminjam) terbesar Asian Development Bank (ADB). Total jatah pinjaman Indonesia 9,4 miliar dollar AS.

Di urutan kedua bertengger China dengan nilai pinjaman 7,4 miliar dollar AS, dan India menempati posisi ketiga dengan nilai pinjaman sekitar 4,9 miliar dollar AS.

"Manfaat ADB adanya jumlah pinjaman yang bisa diberikan kepada negara berkembang dengan suatu term dan rate yang jauh lebih murah dibandingkan rate yang berlaku di pasar," kata Menteri Keuangan Sri Mulyani Indrawati di Kantor Presiden, Rabu (22/4).

Sri Mulyani menjelaskan, Indonesia adalah pemegang saham keenam terbesar di ADB senilai 5,43 persen. Pemegang saham terbesar adalah Jepang dan Amerika Serikat masing sebesar 15,57 persen.

Kemudian menyusul China di posisi ketiga senilai 6,4 persen. Posisi keempat dan kelima diduduki India dan Australia dengan porsi masing-masing 6,32 persen dan 5,7 persen. "Sementara, sisanya sebesar 54,9 persen tersebar ke 61 negara anggota lainnya," kata Sri Mulyani.

Sri Mulyani menambahkan, aset ADB saat ini 70,5 miliar dollar AS dengan jumlah total pinjamannya adalah 30,3 miliar dollar AS.

Menurut Sri Mulyani dengan pertemuan ADB dari tanggal 2 hingga 5 Mei di Bali nanti akan memberi manfaat buat Indonesia.

Pertama adalah bahwa dalam pertemuan ini ADB akan mencapai suatu kesepakatan yang sangat penting yaitu menaikkan jumlah modalnya atau yang disebut dengan general capital increase sebesar 200 persen.

Dengan demikian, kata Sri Mulyani, kondisi itu memungkinkan ADB untuk menaikkan pinjaman kepada berbagai negara di Asia secara cukup signifikan, yaitu sekitar 13 dollar AS hingga 15 miliar dollar AS. (Hans Henricus/Kontan)
