Cyber Security
Cyber security is the effort made to protect computer systems from various threats or illegal access.
Cyber security includes tools, policies, and security concepts that can be used to protect the assets of organizations and users. Cyber security can minimize the entry of threat risks into computer systems.
This protection effort is applied to computing devices, applications, services, and information transmitted and stored in the cyber environment.
Cyber security refers to practices that ensure three important points called the CIA Triad.
These three points are confidentiality, integrity, and availability, as mentioned by Warkentin & Orgeron in the book Pengajaran Berbasis Teknologi Digital by Sandirana Juliana Nendissa.
The CIA Triad is a security model developed to help people understand various aspects of information technology security and is the main concept of cyber security.
Types of Cyber Security
1. Cloud Security
This type of cyber security refers to efforts to protect data stored in the cloud.
Things involved in this protection include technology, control policies, and services that support cloud security.
Cloud security is one of the important aspects of ensuring data security. Some threats to cloud security include data theft, data misuse, and service traffic hijacking
2. Network Security
Network security is the effort to protect internal networks by improving network security.
This protective measure can protect company assets from cyber crime threats and can also manage network traffic to make it more efficient.
One example of network security is the use of antivirus and firewalls to detect threats originating from malware.
3. Application Security
Application security is a type of cyber security used to improve application security against various threats.
Applications can be accessed from various networks, which makes cyber attacks possible. This makes applications vulnerable to cyber threats, so application security needs to be implemented.
Some ways to ensure that security processes work properly are authentication procedures, authorization, encryption, logging, and application security testing.
Cyber Threat Methods
1. Malware
Malware is short for malicious software and is one of the most common cyber threats. This software is created to disrupt or even damage computers.
This threat often spreads through email attachments or downloads that look illegitimate. Types of malware include viruses, trojans, spyware, ransomware, adware, and botnets.
2. SQL Injection (Structured Query Language)
The next type of threat method is SQL injection, which is used to take control of and steal data from a data center.
This vulnerability is exploited by cyber criminals by inserting malicious code into data-driven applications through SQL queries. This is done to steal users' personal information.
3. Phishing
Generally, phishing threats are delivered in the form of official company emails but contain requests for sensitive information. This threat is used in fraud to obtain personal data and information.
4. Man-in-the-Middle Attack
A Man-in-the-Middle attack is a type of threat method in the form of eavesdropping on communication between two individuals to steal data.
One example of a Man-in-the-Middle threat is the use of an insecure wi-fi network, which allows cyber criminals to intercept data sent from a device to the victim's network.
5. Denial-of-Service Attack
The last type of threat method is the Denial-of-Service attack, namely an attack on an internet network that exhausts the resources of a system so that it cannot function properly.
Not only that, a Denial-of-Service attack also indirectly prevents other users from accessing the services of the attacked system.
