{"product_id":"cisco-ios-access-lists","title":"Cisco IOS Access Lists","description":"Cisco routers are used widely both on the Internet and in corporate  intranets.  At the same time, the Cisco Internet Operating System (IOS)  has grown to be very large and complex, and Cisco documentation fills  several volumes. Cisco IOS Access Lists focuses on a critical aspect of the  Cisco IOS--access lists. Access lists are central to the task of  securing routers and networks, and administrators cannot implement  access control policies or traffic routing policies without them. Access  lists are used to specify both the targets of network policies and the  policies themselves. They specify packet filtering for firewalls all  over the Internet. Cisco IOS Access Lists covers three critical areas: *Intranets. The book serves as an introduction and a reference  for network engineers implementing routing policies within intranet  networking. * *Firewalls. The book is a supplement and companion reference to  books such as Brent Chapman's Building Internet Firewalls. Packet filtering is an integral part of many firewall architectures, and Cisco IOS Access Lists describes common packet filtering tasks  and provides a \"bag of tricks\" for firewall implementers. *The Internet.\nThis book is also a guide to the complicated world  of route maps. Route maps are an arcane BGP construct necessary to make  high level routing work on the Internet.  Cisco IOS Access Lists differs from other Cisco router  titles in that it focuses on practical instructions for setting router  access policies. The details of interfaces and routing protocol settings  are not discussed.","brand":"O'Reilly Media","offers":[{"title":"Default Title","offer_id":54224978936152,"sku":"9781565923850","price":44.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0278\/1295\/4195\/files\/9781565923850.jpg?v=1765520127","url":"https:\/\/agendabookshop.com\/products\/cisco-ios-access-lists","provider":"Agenda Bookshop","version":"1.0","type":"link"}
