Therefore, cyber security was developed and created to prevent data destruction and theft. This system works by protecting all information and systems, including networks, applications and data transfer processes. The article specifically will explain more broadly about cyber security and its implementation.
What is Cyber Security
Cyber security is a structured effort to protect systems and all important information from various digital attacks. They work independently or in groups to damage and steal important data. Cyber security measures are specifically designed to ward off threats to all connected systems in relation to networks, applications and data transfer.
- Definition of Cyber Security : Cyber security can be defined as an activity to combat all forms of attacks and data theft or damage to a system that is carried out illegally. This strategy was built to protect all types of digital activities so that they run well without any threats.
- The Importance of Cyber Security for Business : When running a business, it is very important to protect every activity or digital activity so that attacks or damage do not occur that will disrupt the running of the business. Apart from that, every transaction, whether data or financial, can be protected from attacks that could harm the business.
Types of Cyber Security Attacks
Each attack has different goals and methods, so usually the methods used or methods are also adjusted to the type of attack. The following are the types of cyber security attacks.
1. Malware
Malware is an intruder that is created in the form of malicious software. This attack is usually distributed via email, an application, a website, and can even be hidden in a file. Malware will operate on a server, computer network, or infrastructure without the user knowing.

They can infiltrate without users knowing and usually through the act of accidentally installing malware. Attackers use malware to steal data such as personal, financial, or business information. For example, Pony malware is a malware that is most commonly used to steal passwords.
2. Phishing
Phishing generally refers to the activity of stealing personal data and sensitive information such as credit card numbers or bank account information. This type of phishing attack is a type of security attack where the perpetrator disguises himself and sends a message to the target and when the message containing the link is accessed, the attack begins to operate to steal data.
3. Man in the Middle (MitM)
Man in the middle (MitM) is an attack carried out by intercepting communications or data transfer activities in a network between a user and a web server. MitM will impersonate one of the legitimate parties and intercept the transfer of information from one of the parties. The perpetrator does this while sending malicious links or unauthorized information to the two parties so that they do not notice and detect the attack.
4. Distributed Denial of Service (DDoS)
A form of distributed denial of service (DDoS) attack is to make a website and server error or unavailable to users. Traffic engineering by perpetrators is created to flood websites and make them unable to function. DDoS is usually a kind of camouflage for subsequent, more damaging attacks.
Cyber Security Principles
System protection from digital attacks has become an obligation and prevents damage and loss in any form. So the goal of protection is to prevent threats from operating in a system. In implementing protection, there are three principles that must be clearly understood.
1. Confidentiality
The first principle is confidentiality, which is a specialty in the system. This concept was created to limit any illegal access that might occur and only provide access to authorized users. They do this to prevent data leaks and maintain the confidentiality of information.

For example, certain information is restricted and not everyone can access it. The same thing with access to financial data or access to government data. In implementing this concept, they usually also create special access or activate two factor authentication (2FA).
2. Integrity
The second principle is integrity which is aimed at maintaining the confidentiality of all information and data so that it can only be accessed by those who have an interest and are declared as authorized users. This concept must also provide information correctly, accurately and reliably.
3. Availability
The third principle is availability where an information provider must always be available well and consistently to provide accurate information. Apart from that, the meaning of this principle is to be free from harmful activities or unwanted attacks.
Cyber Security Strategy
Cyber security is a priority in every digital activity so that proper protection can prevent detrimental attacks. The following are strategies for implementing cyber security.
1. Vendor Selection
Of course, in implementing a cyber security strategy, vendors become one of the infrastructure supporters who can provide needs as well as raw materials or services. When choosing a vendor, make sure they can provide appropriate services and provide all the needs for building cyber security infrastructure.
2. Information Security Policy
One of the strategies that must be implemented is an information security policy including how to maintain the system being built and how to handle risks that may occur as well as regulating all access. There must be a system that regulates data security and control of each asset. This is a form of protection that prevents threats.
3. Information Security Certification
In cyber security strategy, security certification aims to manage risks to data and information security. This method is used to help develop and monitor the operation of the security system.
4. Employee Training and Education
Of course, carrying out a strategy is related to human resources as operators who run a system. Expert and skilled human resources will help to improve the strategies implemented and all data and information that is protected in a safe and secure position.
Cyber Security Tools
Carrying out cyber security requires adequate infrastructure and the right tools to support all protection activities. The following are tools that can be used to carry out cyber security.
1. Firewalls
A firewall is known as a protection system that works to protect devices from dangerous threats while on the internet network. This means that the firewall works like a wall that blocks every threat. Its function is to protect all information and data and block any information or messages that are disturbing and may contain viruses.
2. Antivirus
Antivirus is software that works consistently to protect the device and ward off any virus threats. This tool works to protect devices and other important information and data from dangerous virus attacks.
3. Intrusion Detection and Prevention System (IDPS)
These tools can be in the form of software or hardware systems that work to monitor and detect attacks and handle these attacks by blocking or hindering the attack.
4. Virtual Private Network (VPN)
Virtual Private Network is a tool that is usually used to protect users when interacting or accessing certain information on the internet. So that activities are safe and protected.
Implementing Proper Cyber Security
Implementing appropriate cyber security will protect digital activities and devices used, including important data and information.
1. Identify Security Risks
Security risk identification is a way to thoroughly detect any dangerous attacks or threats. Knowing every possible threat that will occur, the security system can be improved and strengthened so that it is able to ward off threats.
2. Security Assessment
The infrastructure and security systems that have been built need to be evaluated and detected how strong and safe they are in protecting digital activities, devices and important data or information. Security assessments also function to assess all systems in depth and measurably.
3. Security Planning and Implementation
Once the identification and assessment are known, it is necessary to carry out structured planning and implementation of each security system that has been planned. This implementation will be monitored regarding the accuracy of the system and how reliable its security level is.
4. Security Monitoring and Evaluation
Monitoring and evaluation aims to see that every system built functions well and provides maximum protection for all information.
Cyber security is very useful for all organizations, both businesses and government institutions. Building adequate and appropriate infrastructure will work optimally and comprehensively in preventing any malicious attacks that can damage the system and all information.
