WHAT IS CYBERSECURITY? FULL INFORMATION

CYBERSECURITY?


Cybersecurity is the process of protecting and recovering networks, devices, and programs from any type of Cyber Attack. Cyber-attacks are a threat to organizations, employees, and consumers. They can, in fact, destroy businesses and damage your financial and personal life.


WHAT IS THE BEST DEFENSE?


A robust cybersecurity system has multiple layers of security spread across computers, devices, networks, and programs. But a strong cybersecurity system does not depend only on cyber defense technology; It also depends on people making smart cyber defense choices.


The good thing is that you do not need to be a cybersecurity specialist to understand and practice good cyber defense tactics. In this guide, you will learn more about cybersecurity and also learn about your protection from cyber threats.


CYBERSECURITY


DIFFERENCE BETWEEN CYBERSECURITY, COMPUTER SECURITY, AND IT SECURITY


As mentioned above, cybersecurity helps protect your electronic systems, networks, computers, mobile devices, programs, and data from malicious digital attacks. Cybercriminals can perform a variety of attacks against different types of businesses, which may include accessing, altering, or deleting sensitive data.


Cybersecurity is through an infrastructure that is divided into three major components: IT security, cybersecurity, and computer security.


  • Information technology (IT) security, also known as electronic information security, is essential for data security. While Cybersecurity protects only digital data, IT security protects both digital and physical data from intruders.
  • Cybersecurity is a subset of IT security. While IT security protects both physical and digital data, Cybersecurity protects digital data from unauthorized access, attack, and destruction on your network, computer, and devices.
  • Network security or computer security is a subset of cybersecurity. This type of security uses hardware and software to protect any data sent to the network through your computer and other devices. Network security protects the IT infrastructure and provides protection against information intercepted and altered or stolen by cybercriminals.

TYPES OF CYBERSECURITY


For better security, it is important to know the different types of Cybersecurity. These include important critical infrastructure security, network security, application security, information security, cloud security, data loss prevention, and end-user education.


  • Critical infrastructure security: It is made up of cyber-physical systems like electricity grid and water purification system.
  • Network security: It protects the internal network from intruders by securing the infrastructure. Examples of network security include two-factor authentication (2FA) and the implementation of new, stronger passwords.
  • Application security: It uses software and hardware to protect against external threats that may present themselves at the development stage of the application. Examples of application security include antivirus programs, firewalls, and encryption.
  • Information security: This is known as InfoSec, it protects physical and digital data from unauthorized access, use, change, disclosure, deletion of data.
  • Cloud security: A software-based tool that protects and monitors your data in the cloud to help eliminate the risks associated with on-premises attacks.
  • End-user education: End-user education involves users following best practices such as not clicking on unknown links or downloading a suspicious attachment in an email.

TYPES OF CYBER ​​THREATS


There are several types of cyber attacks that can attack your devices and networks, but they generally fall into three categories: - Categories attacks on confidentiality, integrity, and availability:


  • Attacks on confidentiality - These attacks can be designed to steal your personal identity information and your bank account or credit card information. After these attacks, your information can be sold on the dark web for other people to buy and use.
  • Attacks on integrity - These attacks involve personal or enterprise sabotage, often called leaks. Cybercrime accesses and releases sensitive information to expose the data and influence the public to lose confidence in an individual or an organization.
  • Attacks on availability - This type of cyberattack is intended to prevent users from accessing their own data until they pay a fee or ransom. Typically, cybercriminals will prevent a network and authorized parties from accessing important data, demanding that ransom be paid. Companies sometimes pay the ransom and later fix cyber vulnerability so that they can avoid halting business activities.

There are some types of cyber threats that fall into the three categories listed above.


  • Social engineering is a type of attack on privacy, a process of psychologically manipulating people into performing actions or giving information. Phishing attacks are the most common form of social engineering. Phishing attacks usually come in the form of a deceptive email that tricks the recipient into giving personal information.
  • APTs (advanced persistent threats) - This is a type of attack on integrity, where an unauthorized user intrudes into the network and stays in the network for a long time. APT's intention is to steal data, it does not harm the network. APTs are often in areas of high-value information, such as national defense, manufacturing, and the finance industry.
  • Malware or malicious software - a type of attack on availability. It refers to software that is designed to access or damage the computer without the owner's permission. Malware can do anything to crash your computer system, steal your login information, and send spam using your computer. Many common types of malware include spyware, keyloggers, true viruses, and worms.

Ransomware, another form of malicious software, is also an attack on availability. The goal is to lock and encrypt your computer or device data. Common types of ransomware include crypto-malware, lockers, and scareware. Are included.


THREAT TO CYBERSECURITY


As the cyber-defense strategy is evolving, there are cybersecurity threats, with malicious software and other threats taking new forms. To protect yourself, it is important to know three different types of cybersecurity threats, Cyber ​​Crime, Cyber ​​Attacks, and Cyber ​​Terrorism. Cyber ​​Crime can be committed by one or more persons. Such people target your system for financial gain. Cyber ​​Attacks are often committed to political causes and can be designed to collect and distribute your sensitive information.


HOW TO AVOID CYBER ​​ATTACKS


  • Use only trusted sites when providing your personal information. A good rule of thumb for checking URLs is. If the site includes "HTTPS: //", then it is a secure site. If the URL includes "HTTP: //", pay attention to the missing "s" - avoid entering sensitive information like your credit card data and social security number.
  • Do not open email attachments or click on email links from unknown sources.
  • Always keep your devices updated. Software updates contain important patches to fix security vulnerabilities. Cyber ​​attackers can also target older devices that may not be running the most current security software.
  • Back up your files regularly for additional security in the event of a cybersecurity attack. If you need to clean your device due to a cyberattack, it will help to store your files in a safe, separate place.
