Within the Alerting and Logging modes, further options are available. Snort has two different output modes: Alerting and Logging. Snort has a number of uses: as a sniffer, for intrusion detection, and for the capture of network traffic in a honeypot scenario.
An important part of an attacker’s toolkit is a replacement ifconfig command that does not report interfaces in promiscuous mode. It is important to note that if an attacker has compromised the security of the host on which you run this command, he or she can easily affect this output. TX packets:1282769 errors:0 dropped: 0 overruns: 0 carrier: 0 UP BROADCAST RUNNING PROMISC MULTICAST MTU:1500 Metric:1 When the interface is placed into promiscuous mode, as shown next, the PROMISC keyword appears in the attributes section:Įth0 Link encap: Ethernet HWaddr 00:60:08:C5:93:6B Note that the attributes of this interface mention nothing about promiscuous mode. TX packets:1282868 errors:0 dropped: 0 overruns: 0 carrier: 0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 The following examples show an interface on the Linux operating system when it isn’t in promiscuous mode:Įth0 Link encap:Ethernet HWaddr 00:60:08:C5:93:6B This can be obtained by using the ifconfig command on UNIX-based systems. This is usually represented in a type of status flag that is associated with each network interface and maintained in the kernel. Many operating systems provide a mechanism to determine whether a network interface is running in promiscuous mode.
