Cyber Security

What is Cyber Security?

Cyber Security is the practice of protecting systems, networks, and programs from digital attacks. These attacks are usually aimed at accessing, changing, or destroying sensitive information; extorting money from users; or interrupting normal business processes.

Why is Cyber Security Important?

Cyber Security is important because it encompasses everything that pertains to protecting our sensitive data, personally identifiable information (PII), protected health information (PHI), intellectual property, data, and governmental and industry information systems from theft and damage attempted by criminals and adversaries.

Types of Cyber Attacks

1. Malware: Malware is a type of software designed to gain unauthorized access or to cause damage to a computer. This is potentially the most dangerous type of cyber attack as it can give hackers access to your system and steal sensitive information. It can also be used to disrupt the normal operation of a computer system.

2. Phishing: Phishing is a type of social engineering attack often used to steal user data, including login credentials and credit card numbers. It occurs when an attacker, masquerading as a trusted entity, dupes a victim into opening an email, instant message, or text message. Phising is most common type of cyber attack. It is used to steal sensitive information such as usernames, passwords, and credit card details.

3. Ransomware: Ransomware is a type of malware that encrypts a user’s files and demands payment in exchange for unlocking them. This type of malware is often delivered through phishing emails. One of the most famous ransomware attacks was the WannaCry attack in 2017. In this attack, hackers demanded payment in Bitcoin in exchange for unlocking the user’s files.

4. Trojan: A Trojan is a type of malware that disguises itself as a legitimate file or software to trick users into downloading and installing malware. This type of malware can give cybercriminals access to your system by creating a backdoor. The most common types of Trojans are spyware, adware, and remote access Trojans.

5. Denial-of-Service (DoS) Attack: A DoS attack is a cyber-attack in which the perpetrator seeks to make a machine or network resource unavailable to its intended users by temporarily or indefinitely disrupting services of a host connected to the Internet. This is typically accomplished by flooding the targeted machine or resource with superfluous requests in an attempt to overload systems and prevent some or all legitimate requests from being

6. Man-in-the-Middle (MitM) Attack: Man in the Middle (MitM) attacks occur when a third party intercepts communication between two parties. It can be used to steal login credentials, personal information, or financial information. It can also be used to inject malicious software into the communication.

7. SQL Injection: SQL injection is a type of cyber attack that allows attackers to execute malicious SQL statements that can control a web application’s database server. This type of attack can give attackers access to sensitive information such as usernames, passwords, and credit card details.

Architecture of Cyber Security

1. Network Security: Network security is the practice of securing a computer network infrastructure against unauthorized access. It involves the implementation of security policies and procedures to protect the network from cyber threats.

2. Endpoint Security: Endpoint security is the practice of securing the endpoints of a network, such as desktops, laptops, and mobile devices, from cyber threats. It involves the implementation of security policies and procedures to protect the endpoints from malware, phishing, and other cyber attacks.

3. Cloud Security: Cloud security is the practice of securing cloud computing environments against cyber threats. It involves the implementation of security policies and procedures to protect data, applications, and infrastructure in the cloud from unauthorized access.

4. Application Security: Application security is the practice of securing software applications against cyber threats. It involves the implementation of security policies and procedures to protect applications from malware, phishing, and other cyber attacks.

5. Data Security: Data security is the practice of securing data against unauthorized access. It involves the implementation of security policies and procedures to protect data from cyber threats.

6. Identity and Access Management (IAM): Identity and access management is the practice of managing user identities and controlling user access to resources. It involves the implementation of security policies and procedures to protect user identities and control user access to resources.

7. Security Information and Event Management (SIEM): Security information and event management is the practice of collecting, analyzing, and reporting on security events and incidents. It involves the implementation of security policies and procedures to detect and respond to security threats.

8. Incident Response: Incident response is the practice of responding to security incidents and breaches. It involves the implementation of security policies and procedures to detect, respond to, and recover from security incidents and breaches.

Security is a Shared Responsibility

Security is a shared responsibility. Everyone has a role to play in protecting systems, networks, and programs from cyber attacks. By following security best practices and staying informed about the latest cyber threats, we can all contribute to a safer and more secure digital environment. This is why it is important to stay informed about the latest cyber threats and take steps to protect our sensitive data and information. Lack of awareness and negligence can lead to serious consequences such as data breaches, financial loss, and reputational damage. By taking proactive steps to protect our systems and networks, we can reduce the risk of falling victim to cyber attacks and safeguard our sensitive information.

Security is a Continuous Process

Security is a continuous process. Cyber threats are constantly evolving, and new threats emerge every day. It is important to stay informed about the latest cyber threats and take steps to protect our systems and networks. By following security best practices and staying informed about the latest cyber threats, we can all contribute to a safer and more secure digital environment. Security is everyone’s responsibility, and by working together, we can create a safer and more secure digital world. It is important to stay informed about the latest cyber threats and take steps to protect our systems and networks. It must be noted that security is a continuous process and requires constant vigilance and effort to stay ahead of cyber threats.

Conclusion

Cyber Security is the practice of protecting systems, networks, and programs from digital attacks. It is important to stay informed about the latest cyber threats and take steps to protect our systems and networks. By following security best practices and staying informed about the latest cyber threats, we can all contribute to a safer and more secure digital environment.
