Linux Socket Monitor (LSM) is a lightweight security tool designed to monitor network sockets and Unix domain sockets on a server. It acts as a port monitoring solution that detects newly opened ports and alerts administrators about potential security risks. LSM works by comparing current server sockets with previously recorded socket information. Whenever a new port becomes active, the system sends an alert notification. What Is Linux Socket Monitor (LSM)? LSM continuously monitors: Unlike traditional monitoring tools, LSM ignores already active services and triggers alerts only when a new socket …

Portsentry is a tool to detect port scans and log it. Once a host is targeted by an attacker, a port scan is almost always performed. PortSentry detects such scans by monitoring the unused ports on the host. Upon a connection attempt to one of the unused ports, PortSentry is alerted and has the ability to issue a number of commands in response to the scan. Installation # cd /usr/src/ # wget http://sourceforge.net/projects/sentrytools/files/latest/download

SSH tunneling is used to tunnel all of the traffic from your local machine to a remote server that you have an account. SSH allows users to create TCP tunnels to send data over the network. The amazing thing about SSH tunnels is that they are encrypted. How tunneling works? This works by allocating a socket to listen to port on the local side, optionally bound to the specified bind_address. Whenever a connection is made to this port, the connection is forwarded over the secure channel, and a connection is …
