SNIFFING What is Sniffing? * Sniffing is a technique for gaining access through Network-Based attack. * A sniffer is a program that gathers traffic from the local network, and is useful for attackers looking to swipe data as well as network administrator trying to troubleshoot problems. * Using sniffer, an attacker can read data passing by a given machine in real time or store the data. What does one sniff? A sniffer can grab anything sent across the LAN, Including

might make sense for you. When deploying a SIP trunk you must also consider security measures that should be deployed in accordance with the SIP trunk. To help improve the security it would be to block any routing rules that route traffic from the router to anywhere but the Mediation Server. If you use a VPN server, block any routing rules that route

there was not a valid path for the host. Could possibly have a configuration problem with the router or network where several paths can be taken to arrive at the same place, or where several intermediate systems which can include a router or bride can be involved. Time Exceeded message is a command that is used by the TRACERT along with IP TTL field letting it be known that each router has a successive router in a route. A Port Unreachable message is a message that the traceroute command that the complete

Unit 3 Labs Lab 9: Setting Router Passwords Step 4. Configure the router to require a password of ciscopress when connecting through the console. To do so, start by issuing the line con 0 configuration command, which moves you to console line configuration mode. What does the command prompt look like after using this command? The command line now says: Router(config-line)# Step 11. Press Enter. Does the router prompt you for a password? Does the password ciscopress work? Yes and yes Step

matter of using EIGRP with Cisco equipment and OSPF without? OSPF is pretty cool because it allows us to decide the path through the network by being aware of all links in a given logical topology. OSPF gives us a bit more control, seeing as each router knows about every other link in an OSPF area, allowing us to get really granular path selection. OSPF does require more resources on the device than most other protocols, such as the relatively light DUAL algorithm that sits behind EIGRP. So use OSPF

Answer: Resource starvation attacks typically involve flooding the router with traffic or requests designed to consume all of some limited resource. Target resources may be bandwidth, memory, or even computation. 2. Briefly define the following operating planes as they apply to a router (i) management (ii) control; (iii) data. Which plane handles the actual network traffic? Answer: Theoretically, a router works on three separate domains or planes. The management plane handles administration,
