Second, important website data must be backed up regularly, once a day or once an hour. It should also be noted that it is best to back up data off-site and not on the same server. In case the data is deleted or hijacked by an intruder, data backed up off-site is safe.
Third, in addition to the harm of being invaded by vulnerabilities, you must also guard against malicious attacks. It is best to choose a high-defense server for your website, which can effectively defend against DDOS/CC/WinNuke/Smurf/Land-based/TCP/UDP/ SYN-FLOOD/ICMP and other types of attacks.
