Denial of service (DoS)- This type of attack occurs when a hacker overloads a server or profits device with numerous IMCP (Internet Control Message Protocol) ping requests, such that it is unable to respond to valid requests. By updating to the latest service pack and applying security measure patches, you gage minimize the threat of DoS attacks by reducing the vulnerabilities in the TCP/IP network protocol. Although disabling ICMP can remove valuable troubleshooting tools, it can effectively remove the possibility of DoS attacks. Also, any firewall or security software should be configured to recognize and block these attempts if possible. Back door- In a back door attack, a hacker exploits a coded opening in an application that allows them access to the users computer. By educating users to be wary of inexplicable email sources, attachments, and pirated software and multimedia, you can minimize the possibility of incidents of Trojan Back Door software being installed.

Null sessions- A NULL session is an attack that exploits weaknesses in the NetBIOS networking protocol. By utilizing Windows XP version or later on PCs (or switching to Mac Haha) and making registry changes to require authenticated users, you can effectively remove the possibility of invalid sessions.
