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. An attempt in gaining control to the computer and tracking the movements of an individual or a group with not having a permission is what a cyber-attack attack means. This could be used as a weapon when fighting against another country. This is known as the cyber warfare wherein they choose 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.
A few years back, hackers are doing this just for fun and they used to target a single user computers, however, they were beginning to form groups and these are powerful ones in order to attack big shots. Computer system havng a major breach was reported once by an organization and that it was targeted by hackers whom they are believing to have been connected to a foreign 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.
There is this one certain group of hackers who have sent an email of warning to National Health Security in UK to which that they were being sufficiently kind not to attack them, however, they were stating in the email that servers in the network was simply reachable.
Do not forget about the fact that NHS has computers out there, more than hundreds to think of. 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.
When you solve these kind of issues, it will surely take time and effort. Most of the companies would use the CMMS system in order to deal with maintenance regularly and also the updates happening in the company.
You can do a research about what is happening on the internet but I hope this helps as well.
