It’s important to note that with security, there’s no one-size-fits-all approach. Every network is different and requires skilled professionals to create tailored plans across all fronts: apps, databases, network devices, cloud servers, IT infrastructures, and the often weakest link in the security chain: users. These security plans are living, breathing things that need to be updated, upgraded, and patched on a constant basis, too.
Network security is anything you do to protect your network, both hardware and software. Network administrators (or system administrators) are responsible for making sure the usability, reliability, and integrity of your network remains intact. A hacker is capable of getting into a network and blocking your access, for example by holding a system hostage for a bitcoin ransom. You need an excellent defense in place to ensure you’re protected.
