Internet security generally falls under the jurisdiction of an engineering or systems administration department. A large company or government agency that deals with confidential information probably has its own Internet security department or team that devotes all its time and energy to Internet security. Many companies assign security tasks to the person responsible for system administration when they connect to the Internet. A smaller company could hire an Internet security specialist to log in and configure them with security systems and software.
A firewall is a system created to act as a protective barrier between the outside world of the Internet and the company. A specialist can instruct the firewall to restrict access or allow users to access. The Internet security specialist does this by configuring it to define the type of access that will be allowed or restricted.
First, Internet security specialists are tasked with monitoring the flow of information through the firewall. Security specialists must be able to write code and configure the software to notify them when certain types of activity occur. They can tell the program which activity to allow and what not to allow. They can even program the software to pay you or send you an email in case of questionable activities. Records are kept of all network accesses. Security specialists verify records and anything out of the ordinary. If they see something strange, they must judge whether the activity is innocent or harmful. Therefore, they have to investigate and carry out investigative work, perhaps even locate the user who initiated the action. In other cases, it may be necessary to create a new program to prevent the action from happening again.
Sometimes the Internet security specialist is responsible for virus protection or encryption and user authentication systems. Viruses are programs written with the explicit purpose of damaging a hard drive and can enter a network through infected email attachments or infected portable storage devices, such as CD-ROMs and flash drives. Encryption and authentication are used with any network activity that requires the transmission of confidential information, such as passwords, user accounts, or even credit card numbers. These professionals also ensure that your business meets all government security requirements.
