Cyber Security is the use of tools, techniques, policies, and procedures of preventing any harmful assaults and preventing or recovering networks, devices, systems, and applications from digital intrusions. These Cyberattacks typically try to gain access to, change, or delete critical information, extort money from users, or disrupt normal corporate activities.

Different types of Cyber Security?

Cyber securities are of 5 different types-

• Critical Infrastructure Security: It is used to protect critical infrastructure systems. It is the important systems that society rely greatly upon.  Electricity, hospitals, transport, water purification, and digital services are among them.
• Network Security: It is a method for protecting computer networks against unofficial access, targeted attacks, and opportunistic malware.
• Cloud Security: The security of data, apps, and infrastructure on the cloud is the focus of cloud security.
• IOT (Internet of Things) Security: It refers to the protection of IoT-connected smart devices and networks, like lights, thermostats, smart fire alarms, and other appliances are an example of IoT devices that connects human to the internet without intervention.
• Appliance Security: Vulnerabilities stemming from insecure development procedures in the design, coding, and publication of software or a website are addressed by application security.

Why is Cyber Security Important?

In present day, Cyber security is very important as our society is more dependent on technology and our data is stored online there is a high chance that our data may get leaked. Government, military, business, financial, and medical entities all acquire, analyze, and store massive quantities of data on computers and other devices, making cyber security-critical.

Our security numbers, credit numbers and, bank account data are now kept in cloud storage services such as Dropbox and Google Drive. It doesn’t matters whether you are a small business or a corporate firm they all rely mainly on computer services and store data for which unofficial access or exposure might be harmful.

Present-day cybercrimes are increasing drastically which may lead to breaches of sensitive data, it can hack government data and national security, therefore in recent years,  the importance of cyber security has been taken seriously.

Who needs Cyber Security?

It’s a common misconception that cybercriminals are uninterested in you. Cyber security is essential for anybody who uses the internet. Because most cyber attacks are automated, they target widespread flaws rather than any specific website, network, or organization. All present-day organizations contain sensitive data which is an open treasure for cyber attackers.

• Government: The government needs cyber security to secure sensitive national data, investments, and citizen’s data. Cyber attacks against governments, military groups, and defense suppliers are increasingly supplementing or replacing physical attacks, putting countries at risk. The Government provides services mainly on websites, attackers may try to infiltrate the websites to disrupt national services, and official matters will be damaged.
• Corporate firms: Cyber security has become a must for enterprises of all kinds. It’s made to keep all types of data safe from theft and damage. Without a cyber security policy, your company will be open to cyber threats, making it an easy target for criminal attackers.

What are the types of Cyber Threats?

The different Cyber Threats are following-

• Malware: It is often known as harmful code or malicious software, which is a type of computer program that is designed to harm users. It is software that is installed on a computer with the intent of jeopardizing data.
• Phishing: Cybercriminals send phishing emails that appear to be from reputable sources. Clicking on the link in the email may result in the installation of the malware, revealing sensitive information.
• Man in the Middle Attack: When hackers insert themselves in the middle of a conversation is known as the man in the middle attack (MitM) assault. Once they interrupt the message, they can filter and steal sensitive information as well as provide the user with an alternative response.
• Denial of Service Attack: It attacks and tries to overwhelm systems, and networks prevent them from fulfilling valid requests.

Conclusion

One of the most crucial parts of the fast-paced, ever-changing digital world is cyber security. Its threats are difficult to dismiss, therefore learning how to guard against them and teaching others how to do so is critical.
