1. Malware: Malware is a type of software that causes damage to a computer system. This can include malware like Trojan horses and ransomware.
2. Phishing: Phishing is a type of social engineering attack that aims to trick people into revealing sensitive information, such as login credentials or financial information. This can be done through email, social media, or text messages in the cybersecurity meaning.
3. Denial of Service (DoS) and Distributed Denial of Service (DDoS) attacks: These types of attacks aim to make a website or network unavailable by overwhelming it with traffic.
4. Advanced Persistent Threats (APTs): APTs are long term, targeted attacks that steal sensitive information from a specific organization or individual.
5. Insider Threats: An insider threat is a malicious attack that comes from within an organization, often from a current or former employee.

Protecting Yourself Online:

1. Use Strong Passwords: One of the simplest ways to protect yourself online is by using strong, unique passwords for every account. Avoid using easily guessed information, such as your name or birthdate, in your passwords.
2. Keep Software Up to Date: In cybersecurity meaning Software updates often include security patches that help protect against known vulnerabilities.
3. Be Careful What You Click On: Be cautious when clicking on links or opening attachments, even if they come from a trusted source.
4. Use Antivirus Software: Antivirus software can help detect and remove malware from your computer.
5. Use a Virtual Private Network (VPN): A VPN encrypts your internet connection, making it more difficult for hackers to intercept your data.
6. Backup Your Data: Regularly backing up your data can help ensure that you can restore it in the event of a cyberattack in the cybersecurity meaning.

Basic Terminologies of Cyber Security

• Malware: Malware is short for "malicious software." It is any software that is designed to harm a computer, network, or device. Types of malware include viruses, worms, Trojan horses, ransomware, and spyware.
• Phishing: Phishing is the practice of tricking individuals into revealing sensitive information, such as login credentials or financial information. This is frequently accomplished by using phony websites or emails that seem to originate from reliable sources.
• Social Engineering: Social engineering is the act of manipulating people into performing actions or divulging sensitive information. This can be done through phishing, pretexting, baiting, or other tactics.
• Firewall: A firewall is a security system that controls incoming and outgoing network traffic based on a set of rules and policies. Firewalls can be hardware-based or software-based and are often used to protect a network from unauthorized access.
• Encryption: Encryption is the process of converting plain text into a coded format that is unreadable by anyone except those who have the decryption key. This is used to protect sensitive information, such as credit card numbers or login credentials, from being intercepted and read by unauthorized parties.
• Intrusion Detection System (IDS): An IDS is a system that monitors a network for suspicious activity and alerts administrators when it detects a potential threat. IDSs can be signature-based or behavior-based and can be used to detect known or unknown threats.
• Intrusion Prevention System (IPS): An IPS is a system that actively blocks or quarantines suspicious network traffic. This is done in real-time and is often used with an IDS.
• Virtual Private Network (VPN): A VPN is a network that allows users to securely connect to a remote network over the internet. This can access a company's internal network from a remote location or securely access the internet from a public Wi-Fi hotspot.
• Denial of Service (DoS) Attack: A DoS attack is an attempt to make a network or device unavailable to its intended users. This can be done by overwhelming the network or device with traffic, or by exploiting a vulnerability in the system.
• Distributed Denial of Service (DDoS) Attack: A DDoS attack is a type of DoS attack that uses multiple devices to flood a network or device with traffic. This can make the targeted network or device unavailable to its intended users.
• Vulnerability: A vulnerability is a weakness in a system or network that an attacker can exploit to gain unauthorized access or perform other malicious actions. Vulnerabilities can exist in software, hardware, or processes, and can be discovered through vulnerability scanning or penetration testing.
• Patch: A patch is a software update that is designed to fix a vulnerability or issue in a program or operating system. Applying patches is an important part of maintaining the security of a system or network.
• Risk Management: Risk management is identifying, assessing, and mitigating potential security risks. This can involve implementing security controls, such as firewalls or intrusion detection systems, as well as developing incident response plans and conducting regular security audits.
• Compliance: Compliance refers to the adherence to laws, regulations, and standards that relate to security and data protection. Examples of laws and regulations that organizations must comply with include the General Data Protection Regulation (GDPR) and the Health Insurance Portability and Accountability Act (HIPAA).
