An information security system is made up of five components, namely, software, hardware, application, database and people. All these components combine to do output, process, control and feedback. Information processing includes input; application performs various tasks; database stores information and controls access to it; hardware processes the requests for the application and also monitors the activities of users accessing the database. The final component of an information security system is the network which helps in efficient communication between the components and users.
When you have a security program, you need to address all these components as they are very crucial. A large vulnerability in one component can affect the entire system. Components of information security include disaster recovery plan, firewalls, identity management, application security, fraud management and response, virus protection etc. The entire effort of developing and maintaining an information security system has a single aim and that is to keep your business safe from hackers and other cyber criminals. So, you should make a dedicated team of professionals to look after all components of information security so that you can focus only on business and not on technology and other aspects of IT.
While planning an information security system, you need to identify the main components of information security. The first and foremost important component is the application or software. The application is the core of the security program as it serves all the functions of other components. It is very important that the application is designed and developed with a security in mind. The application security should be strong enough to protect against external threats and internal threats as well. So, the application must be developed keeping in mind the main components of information security.
As far as possible, your components of information security should provide 100% confidentiality, integrity, and availability. Also, they should be extensible and easy to customize and upgrade in the future. In order to provide maximum confidentiality, integrity, and availability, your components of information security should store sensitive information only in physically protected locations. The physical security should be effective and reliable. This will help you to protect your confidential information from unauthorized access.
In fact, these three components of information security are interrelated and are not possible to achieve separately. Therefore, these components of information security must be implemented together for maximum protection and security. However, when there is no physical separation, then all the components of information security cannot be applied successfully and you would not be able to provide total coverage. So, you should use physical partitioning and network segmentation in order to secure your information systems effectively.
All the key elements of information security policy must be combined into a single comprehensive solution. Each of these components is very important for the proper functioning of a computer network. Some of these key elements of information security policy are access control, confidentiality, and availability. Access control ensures the security of data that is entering the system. It also prevents the unauthorized access to the information or the processing of the data. By increasing the level of confidentiality, integrity, and availability, the security of the network is increased as well.
Confidentiality ensures the confidentiality of the data and the information that is stored in the computer. By using encryption, the confidentiality of the information will be increased. Besides, by making sure that the confidentiality of the information is maintained at all times, the security of the system is further guaranteed. Moreover, by ensuring the availability of the important data and applications, the network will function smoothly and effectively.
Last but not the least, availability ensures that the system is not affected by any loss of data or applications that are critical to the functioning of the company. The availability of the applications and data allows the network to function normally. However, the lack of these components of information security system may create problems to the business. So, it is necessary to combine all these key components of information security policy so that your computer network remains one of the most secure, safe, and reliable in the industry.
