The Importance Of Security In The System
The importance of security in the system is certainly related to the information in the system itself. Important information in a system that falls into the hands of other parties will certainly harm the owner of the information, both companies and individuals.
Information security consists of 3 main things, namely:
Protecting Company Data and Information
Protecting company data and information from unauthorized parties is vital.
The confidentiality aspect is an effort to protect information from people who are not entitled to access company data and information.
Privacy is more focused on data that is confidential and important. Efforts that can be made to increase privacy is to use cryptography. Cryptography is a science that studies mathematical techniques related to information security aspects such as data authentication, data integrity, and data validity.
The availability aspect relates to the method where the system checks whether the information is truly genuine or can also check that the party accessing the information is a person who has the right or not.
Watermarking or digital signature is the first method that can prove the authenticity of documents.
Watermarking can also function as intellectual property as well as signing a legal document resulting from the author’s work.
The second is related to access control, which relates to restrictions on people who can access information.
People who want to access information must be able to show that they are authorized users to access information in the system.
Information must not be changed or accessed by someone who does not have permission for the information to be accessed.
In the presence of threats such as viruses, trojan horses, other users who change information without permission.
Information systems require an accurate representation of the physical system they represent.
Firewall Functions Within the Company
With regard to the privacy of information and company data, of course, it requires a network security system, namely a firewall.
Firewall is a method or mechanism that is applied to hardware, software or the system itself which aims to protect, either by filtering, limiting activities related to access to private networks from outside networks.
This system can be a server, workstation, local area network or LAN. The use of firewalls in general is intended to serve:
Machine / Computer
Each individual computer machine that is connected directly to an external network or the internet so that it can protect the information and data on the computer.
A computer network consisting of one computer and various types of network topologies used so that it can be owned by a company or organization.
As mentioned earlier that a firewall is a security system that is able to provide protection in a computer system or computer network.
As for the managed service firewall, it is a firewall application service provided by IT companies for other companies that need it.
The following is an illustration of how a firewall works.
Regulating And Controlling Traffic.
In addition to limiting access, a firewall is also able to regulate and control data traffic in a system.
In the next gen firewall or next generation firewall that has the ability to control data traffic.
Perform Authentication Against Access.
The main function of a firewall is to authenticate access by people whether it is legal or not.
Protecting Resources In Private Networks.
Protecting resources in a private or dedicated network is a required capability of a firewall.
A private network is a network that can only be accessed by network owners, either organizations or individuals with access restriction methods.
Record All Events, And Report To Administrator
System logging or event logging is the job of the firewall so that administrators can monitor and take appropriate action if something happens.
Firewalls have 4 types, including:
Personal firewall is a firewall created to protect computers connected to the network so that unwanted access will be restricted by the firewall.
This type of firewall evolved into a collection of programs that aim to secure the computer as a whole, such as: Microsoft Windows Firewall
Network firewalls are specially designed to protect the network as a whole from various attacks. Usually has two forms, namely a dedicated device or as a software installed on a server such as: Internet Security and Acceleration Server (ISA Server), Cisco PIX
IP Filtering Firewall
Is a firewall that works at the packet level.
Proxy server: how the proxy server works, it is seen when the user connects to the proxy server with client software, which the proxy server will duplicate the communication.
