In the whole world, recently, there have been a rise in cyber-attacks which has been becoming the greatest concern of almost all of the influential organizations. You might be wondering what a cyber-attack is. A cyber-attack would be an attempt in gaining control to the computer and tracking the movements of an individual or a group with not having a permission. In fighting against another country, this could be the newest form of weapon. They would be choosing not to waste bullets and money since a country could be shut down in just a few minutes through aiming power grids or national banks or others and this is known as the cyber warfare.
For the sake of having fun, hackers before use this and would choose a single user computers to attack, however, they were starting to form groups and these are powerful ones so that they would be able to attack big shots. There was a report once by an organization about having a major breach on its computer system, also that it was being targeted by hackers whom they would like to believe to have been connected to another country. Email and other crucial documents were being stolen by these hackers.
Emails like Gmail was once attacked wherein the accounts of high state officials, journalists, military personnel and so many more were hacked, in case you do not know this. Tracing the attack was the only action taken. Hackers were said to be found from a province to which that they were also saying that they must not point fingers without a proper proof to present.
An email of was once sent by this one particular group of hackers which they have chosen not to attack but to rather say their servers in the network was simply reachable, this email was sent to the National Health Security in UK.
Remember that the NHS has so many computers out there, millions for that matter. This kind of organization will really have a huge job when it comes to the IT knowing that they have wings on the different countries around the world. If you think about it, it would cost them millions for a system update, so it would be more when all of their systems will be updated. The software that most of the NHS is using is proprietary which means that they will have to develop their own software to be able to do their work.
So solving a problem like such will really take too much effort and time. In order to deal with maintenance regularly and also the updates happening in the company, most of the companies choose to use the CMMS system.
You can do a research about what is happening on the internet but I hope this helps as well.
