SCADA is an important innovation for the industrial world. It stands for supervisory control and data acquisition”. A scada system collects data from various instruments, analyzes the data and controls the instruments.

Entire plants can be controlled by a central computer with scada software. These are used in complex industrial applications like oil and gas, nuclear power generation and steel making industry. Even the most complex industrial environments have been handled by scada systems.

These are also used in other complex and important sectors such as telecommunications and water treatment plants. The various instruments that build up a plant can be controlled and monitored using the scada software on a central computer.

Every time a system is modified, hacked or any problem occurs, the system gets to know about it and suitable measures can be taken to prevent any tragedy. There have been reports about some Chinese hackers attempting to hack US power grid and create a scare.

Penetration testing is crucial to protect vast infrastructure and industrial plants. Hackers can cause widespread damage. Various leaks and windows should be identified and fixed and this is where penetration testing comes in. Penetration testing can help secure entire systems.

The critical infrastructure is prone to attacks by hackers and terrorists. Penetration testing can help find out any security windows and fix them before someone takes advantage of them to launch any attacks on the systems.

Intrusion detection systems can help know when the attacks have happened so that appropriate measures can be taken. The unsecured code in various software is prone to attacks. The remote terminal units also have to be secured from unauthorized access and attacks.

The communication taking place between various devices is also monitored. There can be security windows in both the hardware and software. Employees should also be monitored. So a lot of surveillance is needed.
