Cyber Security Threats are increasing in number daily because of the changing technology and low-level security measures used by organizations for the protection of their networks, systems, servers, and datasets.
Actually, open networks and servers are more in danger than secure datasets. Online hackers first attack the networks to get into the logs of the users and steal their IDs, IPs, and all. That is to access their online accounts to steal their confidential data without the user’s consent. Let’s continue!
