INTRODUCTION
Cyber Security is the protection of internet connected system including hardware, software & program or data form cyber-attack. Cyber-crime is defined as any criminal activity which takes place on over the computer or internet technology. Cyber-crime is most common crime which plays very traffic role in modern world.
Cybersecurity is the practice of protecting systems, networks, and programs from digital attacks. These cyber-attacks are usually aimed at accessing or destroying sensitive information; extorting money from users; or interrupting normal business processes, implementing effective cybersecurity measures is particularly challenging today because there are more devices than people, and attackers are becoming more innovative.
A successful cybersecurity approach has multiple layers of protection spread across the computers, networks, programs, or data that one intends to keep safe. In an organization, the people, processes, and technology must all complement one another to create an effective defense from cyber-attacks.
A unified threat management system can automate integrations across select Cisco Security products and accelerate key security operations functions: detection, investigation, and remediation.

These cyberattacks are usually aimed at accessing, changing, or destroying sensitive information; extorting money from users; or interrupting normal business processes.

Cybersecurity refers to a set of techniques used to protect the integrity of networks, programs and data from attack, damage or unauthorized access.
From a computing point of view, security comprises cybersecurity and physical security — both are used by enterprises to protect against unauthorized access to data centers and other computerized systems. Information security, which is designed to maintain the confidentiality, integrity, and availability of data, is a subset of cybersecurity. The use of cyber security can help prevent cyber-attacks, data breaches, and identity theft and can aid in risk management.
Why cybersecurity is important?
In today’s connected world, everyone benefits from advanced cyber defenses programs. At an individual level, a cybersecurity attack can result in everything from identity theft to extortion attempts, to the loss of important data like family photos. Everyone relies on critical infrastructure like power plants, hospitals, and financial service companies. Securing these and other organizations is essential to keeping our society functioning.
Everyone also benefits from the work of cyberthreat researchers, like the team of 250 threat researchers at Talos, who investigate new and emerging threats and cyber-attack strategies. They reveal new vulnerabilities, educate the public on the importance of cybersecurity, and strengthen open-source tools. Their work makes the Internet safer for everyone.
Types of Cyber Security threats
Phishing
Phishing is the practice of sending fraudulent emails that resemble emails from reputable sources. The aim is to steal sensitive data like credit card numbers and login information. It’s the most common type of cyber-attack. You can help protect yourself through education or a technology solution that filters malicious emails.
Ransomware
Ransomware is a type of malicious software. It is designed to extort money by blocking access to files or the computer system until the ransom is paid. Paying the ransom does not guarantee that the files will be recovered, or the system restored.
Malware
Malware is a type of software designed to gain unauthorized access or to cause damage to a computer.
