Cyber Security and Data Protection

Study Notes

Today's generation heavily relies on the internet for various activities like booking, ordering, and accessing data stored on the cloud through different devices.
The increase in access points and data availability online has created a favorable environment for hackers to exploit vulnerabilities and create malicious software.
Various types of cyber attacks include malware, phishing, password attacks, DDoS, man-in-the-middle attacks, drive-by downloads, malvertising, and rogue software.
Major companies like eBay, AOL, Evernote, and Adobe have experienced significant cyber breaches despite having security measures in place.
Cyber security plays a crucial role in protecting against cyber attacks, data breaches, identity theft, and aids in risk management for individuals and organizations.
The CIA triad (Confidentiality, Integrity, Availability) forms the basis of most security policies for ensuring data security.
Cyber security activities aim to protect against unauthorized modification, deletion, and access by identifying vulnerabilities, threats, and risks.
Vulnerabilities refer to weaknesses that can be exploited by attackers, threats are incidents that can cause harm, and risks involve potential loss or damage when threats exploit vulnerabilities.
Risk management strategies involve assessing risks, considering stakeholder perspectives, and implementing measures to mitigate risks effectively.
Cyber security defense mechanisms involve identifying malware, analyzing affected parties and systems, and patching vulnerabilities to restore normalcy after a cyber attack.
