The measures taken against everything enumerated above can vary as well. You can install firewalls as a barrier for unauthorized access or antivirus software for not allowing any. The best way to keep data safe is to add encryption to it, which means converting some of it into a code with secure format. Multi-factor authentication and patch management can also be simple but effective measures. Adding layers to authentication makes breaking into accounts more difficult and fixing up any random bug that may appear might save networks from being compromised by unauthorized parties.
