    What is Cyber ​​Security

    What is Cyber ​​security? 

    Cyber ​​security 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 harm your financial and personal life.

    What is the best defense?

    A robust Cyber ​​security system has multiple layers of security spread across computers, devices, networks, and programs. But a strong Cyber ​​security 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 cyber security specialist to understand and practice good cyber defense tactics. In this guide, you will learn more about cyber security and also learn about your protection from cyber threats.

    Differences between Cyber ​​security, Computer Security and IT Security

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

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

    • Information technology (IT) security, also known as electronic information security, is essential for data security. While Cyber ​​security protects only digital data, IT security protects both digital and physical data from intruders.
    • Cyber ​​security is a subset of IT security. While IT security protects both physical and digital data, Cyber ​​security protects digital data from unauthorized access, attack and destruction on your network, computer and devices.
    • Network security or computer security is a subset of Cyber ​​security. 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 cyber criminals.

    Types of Cyber ​​security

    For better security, it is important to know the different types of Cyber ​​security. These include critical 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 system such as 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 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: It 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 suspicious attachments in email, etc.

    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 include personal or enterprise sabotage, often called leaks. Cybercrime accesses and releases sensitive information for the purpose of exposing the data and influencing the public to lose confidence in an individual or an organization.
    • Attacks on availability – The purpose of this type of cyberattack is to prevent users from accessing their own data until they pay a fee or ransom. Typically, cybercriminal will prevent a network and authorized parties from accessing important data, demanding that ransom be paid. Companies sometimes pay a 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.

    1. Social engineering – is a kind of attack on privacy, it is 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 which trickes the recipient into giving personal information.
    2. APTs (advanced persistent threats) – It is a type of attack on integrity, where an unauthorized user infiltrates 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.
    3. Malware or malicious software – There is 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, to 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 Cyber ​​security

    As cyber-defense strategy is evolving, so are Cyber ​​security threats, with malicious software and other threats taking new forms. To protect yourself, it is important to know three different types of Cyber ​​security 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 for political reasons and can be designed to collect and distribute your sensitive information.

    What to do to avoid Cyber ​​Attacks

    Follow these steps to increase your cyber safety knowledge.

    • 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 Cyber ​​security attack. If you need to clean your device due to a cyber attack, it will help in storing your files in a safe, separate place.
