Data vs. Information
Data are unprocessed values, while information is organized or analyzed data that becomes meaningful.
Defining Cybersecurity
Cybersecurity aims to protect digital systems, networks, devices, and data.
What was the original purpose of ARPANET?
The original purpose of ARPANET was to enable secure and reliable communication between military and research institutions and allow resource sharing among connected computers.
Why is cybersecurity important for critical infrastructure?
Cybersecurity protects essential sectors like energy, healthcare, transportation, and finance from cyberattacks that could disrupt services, threaten public safety, and cause economic damage.
Three pillars of cybersecurity importance:
- Protects sensitive data and privacy
- Prevents financial and operational losses
- Maintains trust and ensures business continuity
Understanding Cybercrime
Cybercrime is any illegal act carried out using computers or networks. It usually targets data, money, systems, identity, or reputation.
Common Threats
Ransomware encrypts an organization’s data and blocks access until payment is made.
What makes cybercrime different from traditional crime?
Cybercrime is conducted digitally, can be executed remotely across borders, often allows anonymity, and can impact many victims quickly compared to traditional crime.
Why are insider threats considered dangerous?
Insiders already have authorized access to systems and data, making it easier to misuse information or bypass security controls.
The risks of cracked software
The cracked software likely contained malware such as a Trojan or spyware that created a backdoor, allowing attackers to access and steal company data.
Governance and Global Standards
The National Cybersecurity Strategy (2025–2031) includes Governance, Protection, Innovation, Resilience, and Partnerships.
International and Legal Frameworks
The Global Cybersecurity Index is issued by the International Telecommunication Union (ITU). Additionally, GDPR requires organizations to report a data breach within 72 hours.
What does the GDPR mainly aim to ensure for individuals?
The GDPR ensures protection of personal data and privacy rights, giving individuals greater control over their information.
Which international organization releases the GCI?
The International Telecommunication Union (ITU) releases the GCI.
What is the UAE law regarding cybercrimes?
