is the relationship between vulnerability scanning (automated) and pen-testing (expert-driven manual testing). Both involve a proactive and concerted attempt to identify vulnerabilities that could expose the organization to a potential malevolent attack. Vulnerability scanners are great at identifying ‘low-hanging’ vulnerabilities, such as common configuration mistakes or unpatched systems that offer an easy target for attackers. What they are unable to determine is the context or nature of the

company by freeing up more space on its own main server. In today’s business Information technology (IT), infrastructure and systems on the cloud have benefits of variable pay per use costs, with better technology and high scalability. This is a “hot issue” in the technology world because it affects the way we spend our money. The idea came about by coming up with one place to file, in a central location away from the main computer. There must be a main server that is big enough to route files to. This
