IT security is a fundamental part of an organisation, and the department utilises technology, processes and measures to protect an organisation’s systems, networks and data from crimes and attacks.
Attacks are complex and can result in businesses not only losing substantial amounts of money but also vital, sensitive or protected information. Crimes are constantly evolving, and security departments should have the ability to protect against instances that occur.
IT security involves the ability to evaluate current practices that are intended to prevent an attack on an organisation’s IT systems. The threats towards and weaknesses within the organisation’s systems should continually be assessed and a method of protection should be implemented to reduce the possibility of an attack. A security plan should be used, including ways of monitoring security measures and details of what actions would be taken if an attack occurred.
