Chapter 1  Outlines: Definition of Cybersecurity Elements of Cybersecurity The Importance of Cybersecurity  Cybersecurity Cybersecurity refers to a set of practices and technologies designed to protect systems, networks, software, and data from unauthorized digital attacks. Its goal is to ensure information safety by maintaining confidentiality, integrity, and availability.  Elements of Cybersecurity Confidentiality Ensures that data is accessible only to authorized individuals. Integrity Protects data from unauthorized alteration or manipulation. Availability Ensures systems, services, and data are accessible when needed. Elements of Cybersecurity  The Importance of Cybersecurity 1.Protecting Sensitive Data With the continuous growth of digital data, safeguarding data from theft or manipulation is crucial. 2.Combating Digital Threats These threats include viruses, malware, and ransomware attacks.  The Importance of Cybersecurity 3.Ensuring Business Continuity Cybersecurity protects systems and networks from disruptions that could lead to financial and reputational losses. 4.Compliance with Laws and Regulations Many countries and organizations enforce cybersecurity standards to ensure the protection of personal and corporate data. Chapter2  Outlines: threat Types of Cyber threats  Threat In cybersecurity, a threat refers to any potential event, actor, or condition that could compromise the confidentiality, integrity, or availability of data, systems, or networks.  Typs of Cybersecurtiy threats 1.Malware (Malicious Software): Includes viruses, worms, trojans, ransomware, spyware, and adware. Example: A ransomware attack encrypts files and demands payment for decryption. 2.Phishing: Fraudulent attempts to obtain sensitive information by pretending to be a trustworthy entity via email, messages, or websites. Example: A fake bank email asking for login credentials..  Types of Cyber threats 3.Denial of Service (DoS) and Distributed Denial of Service (DDoS): Overwhelming a system, server, or network with traffic to make it unavailable to legitimate users. Example: Flooding a website with traffic to crash it. 4.Social Engineering Manipulating individuals into divulging confidential information. Example: Pretending to be IT support to gain access to systems Chapter3  Outlines: Whats is Phishing  Phishing Phishing is a type of cyberattack that uses deceptive techniques to trick individuals into revealing sensitive information, such as usernames, passwords, or credit card details.  Common Phishing Techniques: 1.Email Phishing: Fraudulent emails that appear to come from legitimate sources, asking users to click on malicious links or provide personal information. 2.Spear Phishing: Targeted attacks aimed at specific individuals or organizations, often using personalized details to seem more convincing. 3.Smishing (SMS Phishing): Phishing attempts made through text messages, encouraging victims to click on malicious links or share sensitive data.  Common Phishing Techniques: 4.Vishing (Voice Phishing): Phone calls pretending to be from trusted entities, like banks or government agencies, to extract personal or financial information. 5.Clone Phishing: Duplicating legitimate emails and replacing links or attachments with malicious ones. 6.Fake Websites: Creating websites that look identical to trusted ones,.tricking users into entering sensitive data Chapter 4  Outlines: The Evolution of Cyber Threats and the Associated Risks The Evolution of Cyber Threats and the Associated Risks As technology and the internet advance, threats become more complex and varied, requiring the continuous development of protection strategies. Below is an overview of the evolution of these threats and risks: The Evolution of Cyber Threats and the Associated Risks Traditional Attacks (Viruses and Malware) Previous Threats: In the past, viruses and malware were typically limited to software that harmed or disrupted the functioning of the system, such as traditional viruses or spyware. Evolution: such as malware that seeks to infiltrate systems stealthily for financial or espionage purposes. The Evolution of Cyber Threats and the Associated Risks Hacking Previous Threats: Hacks occurred mainly through weak passwords or vulnerabilities in software Evolution: Attacks have become more complex with methods such as social engineering. The Evolution of Cyber Threats and the Associated Risks Cloud Threats Previous Threats: Attacks were confined to local devices and systems. Evolution: attacks are increasingly aimed at targeting cloud servers, exploiting vulnerabilities like misconfigurations in cloud services. Chapter5  Outlines: Firewalls Encryption Cybersecurity Defense Strategies  Cybersecurity Tools and Techniques Cybersecurity tools and techniques are essential for ensuring the protection of data and systems from increasing threats and attacks in the digital world. Some of the key tools are:  Firewalls Firewalls Firewalls are fundamental in protecting networks from external attacks. They filter incoming and outgoing traffic based on specific policies and rules. Firewalls can be either hardware or software-based and are used to monitor networks and restrict access to systems based on connection types (IP, protocols, ports, etc.).  Encryption Encryption Encryption is a vital technique for protecting data from unauthorized access. It involves converting data into an unreadable form using an encryption key, making it impossible or extremely difficult for attackers to retrieve the original data without the correct key. Encryption is used in various applications such as securing email communications, protecting online financial transactions, and safeguarding stored data.  Cybersecurity Defense Strategies Cybersecurity Defense Strategies The goal of cybersecurity defense strategies is to enhance the system's ability to counter increasing attacks and threats.  Cybersecurity Defense Strategies Handling attacks depends on early detection and well-planned execution of appropriate countermeasures. Here are some key strategies: Incident Response Continuous Documentation and Updates Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS) Preventive Security Techniques Training and Awareness Chapter6  Outlines: International and Local Data Protection Laws  International and Local Data Protection Laws Data protection laws are numerous and varied depending on the region and applicable regulations, but there are some general principles aimed at ensuring data privacy and protecting rights:  International and Local Data Protection Laws 1. International Laws: General Data Protection Regulation (GDPR) – European Union: The GDPR is the most prominent international law in the field of personal data protection. It ensures the privacy of citizens in the European Union and defines how personal data should be collected, used, and stored. Some key principles include: Transparency: Individuals must be aware of how their data is used. Purpose Limitation: Data should be collected for specific, legitimate purposes. Data Retention Limitation: Data should be kept only for as long as necessary. Right of Access and Rectification: Individuals have the right to access and correct their data if inaccurate.  International and Local Data Protection Laws Children’s Online Privacy Protection Act (COPPA) – United States: This law aims to protect the privacy of children under the age of 13 online. It mandates parental consent before collecting personal data.from children Personal Information Protection and Electronic Documents Act (PIPEDA) – Canada: This law protects personal data in the private sector. It requires individuals' consent for the collection and use of their.data  International and Local Data Protection Laws 2. Local Laws: Saudi Arabia: In Saudi Arabia, the "Executive Regulation of the Personal Data Protection Law" was issued to ensure personal data protection. Some key points include: Consent: Consent must be obtained from individuals before collecting their data. Security: Data must be protected from leakage or breaches. Rights: Individuals have the right to know how their data is used and to delete or modify it.  International and Local Data Protection Laws United Arab Emirates: The UAE has data protection laws in place that align with international principles, such as the "UAE Data Protection Law", :which includes.Consent from individuals before collecting and using their data.Confirmation of individuals' rights to access and correct their data Egypt: The Personal Data Protection Law (2020) aims to protect individuals' rights related to their personal data and enhances transparency in how personal data is collected and used  International and Local Data Protection Laws Individuals' Rights: This includes the right of individuals to control their personal data, such as: Right of Access: The right to know what data is being collected and how it is used.
