(Choose two. Explanation: Port security is the most effective method for preventing CAM table overflow attacks. A web server administrator is configuring access settings to require users to authenticate first before accessing certain web pages. A packet filtering firewall is able to filter sessions that use dynamic port negotiations while a stateful firewall cannot. document.getElementById("ak_js_1").setAttribute("value",(new Date()).getTime()); document.getElementById("ak_js_2").setAttribute("value",(new Date()).getTime()); What are two security features commonly found in a WAN design? Ideally, the classifications are based on endpoint identity, not mere IP addresses. The idea is that passwords will have been changed before an attacker exhausts the keyspace. Harden network devices. A client connects to a Web server. One has to deploy hardware, software, and security procedures to lock those apps down. Match the network monitoring technology with the description. specifying source addresses for authentication, authorization with community string priority, host 192.168.1.3, host 192.168.1.4, and range 192.168.1.10 192.168.1.20, host 192.168.1.4 and range 192.168.1.10 192.168.1.20.
