Uncover vulnerabilities and potential threats by scanning hosts on your network. Host scanning helps you detect vulnerabilities in a host that may be picked out for attack. Vulnerability scanning is performed to identify potential weaknesses. 4. Network Service Discovery & Registration 5. PING Ping is used to test the reachability of a host on an Internet Protocol (IP) network. Ping works by sending an Internet Control Message Protocol (ICMP) Echo Request to a specified interface on the network and waiting for a reply. When a ping command is issued, a ping signal is sent to a specified address and it responds by sending an echo reply packet. 6. Port Scan An application can send traffic and listen on a particular port. The combination of an IP address and a port enables routing devices and the endpoint to ensure that traffic reaches the intended application. A port scan can provide a wealth of information about a target system. In addition to identifying if a system is online and which ports are open, port scanners can also identify the applications listening to particular ports and the operating system of the host. 7. Reverse/DNS Lookup - Find all DNS records for a domain name with this online tool. The DNS records include but are not limited to A, AAAA, CNAME, MX, NS, PTR, SRV, SOA, TXT, CAA, DS, and DNSKEY. - Performing a reverse DNS lookup allows users to find the hostname of an IP address. 8. Bluetooth Scan and Advertiser - Send advertising packets (PDUs) to broadcast data, and to allow other devices (scanners) to find & connect to them. - Searches the local area for Bluetooth-enabled devices & requests some information about each one 9.
