NGFW menawarkan opsi hemat biaya bagi perusahaan yang ingin meningkatkan keamanan perangkat dasar melalui kesadaran aplikasi, layanan inspeksi, sistem perlindungan, dan alat kesadaran ancaman.<\/p>\n<h2>Perbandingan Next-Generation Firewall vs. Firewall Tradisional<\/h2>\n<p>Meskipun NGFW dan firewall tradisional memiliki tujuan yang sama, yaitu melindungi jaringan dan aset data organisasi, ada beberapa perbedaan utama.<\/p>\n<p>Kesamaan:<\/p>\n<ul class=\"default-list\/\">\n<li>Penyaringan paket statis untuk memblokir paket pada antarmuka lalu lintas jaringan.<\/li>\n<li>Inspeksi paket stateful.<\/li>\n<li>NAT, PAT, dan pengaturan koneksi VPN.<\/li>\n<\/ul>\n<p>Perbedaan utama:<\/p>\n<ul class=\"default-list\/\">\n<li>NGFW menawarkan inspeksi paket mendalam yang melampaui inspeksi port dan protokol dengan memeriksa data yang dikirimkan dalam paket jaringan.<\/li>\n<li>NGFW menambahkan inspeksi pada level aplikasi, pencegahan intrusi, dan kemampuan untuk memanfaatkan data dari layanan intelijen ancaman.<\/li>\n<\/ul>\n<p>NGFW juga memperluas fungsi firewall tradisional dengan beroperasi dalam mode rute (firewall bertindak sebagai <a href=\"https:\/\/www.linuxid.net\/istilah\/router\/\">router<\/a>) dan mode transparan (firewall memindai paket seperti &#8220;jembatan&#8221; dalam kabel), sambil mengintegrasikan teknologi manajemen ancaman terbaru.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Apa itu Next-Generation Firewall (NGFW)?
