Cybersecurity includes the security of computer-based devices and information from unintended or unauthorized access. A cyber-attack takes numerous forms, including theft or unauthorized access of computers, laptops, tablets, or mobile devices. A remote attack on IT systems or websites attacks the information held in third-party systems such as cloud devices. If a cyber-attack strikes, it can result in financial losses, increased recovery costs, and substantial damage to reputation. So, to protect the organization and computer systems, every Organization requires a professional cybersecurity team. The public and private areas posted 313,735 openings for cybersecurity professionals between September 2017 and August 2018, and it's expected that there will be about 3.5 million unfilled industry positions by 2021.
