The goal of taking the CompTIA Security+ exam is to prove that you’ve mastered the worldwide standards for foundation-level security practitioners. The exam gives you a perfect opportunity to validate your knowledge and understanding of the computer security field, and it is an appropriate mechanism for many different individuals, including network and system administrators, analysts, programmers, web designers, application developers, and database specialists, to show proof of professional achievement in security.
Why Focus on Security? Security is not something that we want to have to pay for; it would be nice if we didn’t have to worry about protecting our data from disclosure, modification, or destruction from unauthorized individuals, but that is not the environment we find ourselves in today. Instead, we have seen the cost of recovering from security incidents steadily rise along with the number of incidents themselves. Cyber-attacks and information disclosures are occurring so often that one almost ignores them on the news.
How a firm deploys its firewalls determines what is needed for security policies for each firewall. As will be discussed later, the security topology will determine what network devices are employed at what points in a network. At a minimum, the corporate connection to the Internet should pass through a firewall. This firewall should block all network traffic except that specifically authorized by the firm. Blocking communications on a port is simple—just tell the firewall to close the port. The issue comes in deciding what services are needed and by whom, and thus which ports should be open and which should be closed.
