Secure Shell Secure shell is a secure communication protocol that can be used for remote administration (like a webserver) over a terminal. It is technically a secure version of telnet. A shell or console on any system is meant to execute commands on it and control it. Telnet used to do this. But telnet transmitted all data in plain text format and hence is insecure by design. To overcome this, the communication is wrapped with [...]

However the setting is hidden inside. To access [...]

Securing confidential data We often need to put some confidential data on the hard drive, in which case it becomes essential to have some kind of security mechanism to keep it hidden from unauthorised access of any kind.

One way to protect such data with security is to put them in a directory that is password protected or is [...]

Command Line The zip command can be used to create password protected zip files easily. Here is a quick example $ zip -P *secret* compressed.zip file.txt Note that the P is capital. Can also type “–password” instead of the “-P”. $ zip –password *secret* compressed.zip file.txt The above approach might be a bit insecure since the password is visible and the command is stored in the terminal history and can be retrieved.
