Q & A

What is the primary focus of the session presented by Arch from Edura?

The primary focus of the session is to provide an understanding of cybersecurity, its fundamental concepts, and how it is applied in real-world scenarios to protect against cyber threats.

Why is cybersecurity important in today's interconnected world?

Cybersecurity is important because it helps protect against cyber attacks that can damage devices and steal sensitive information, which is crucial given the reliance on internet and networks in our daily lives and global economy.

What are some examples of cyber attacks mentioned in the script?

Examples of cyber attacks mentioned include malware, phishing, man-in-the-middle attacks, denial of service attacks, malvertising, and ransomware.

How do cyber criminals typically exploit sensitive data?

Cyber criminals typically exploit sensitive data by stealing it to sell to third parties for profit, exposing host vulnerabilities, or engaging in politically and socially motivated hacking.

What is malware and how does it affect a computer system?

Malware is malicious software that includes spyware, viruses, and Trojans, which are injected into a computer to corrupt it. It can cause damage, data theft, and other harmful effects.

What is the purpose of the CIA Triad in cybersecurity?

The CIA Triad stands for confidentiality, integrity, and availability, and it serves as a fundamental concept in cybersecurity to ensure that data is protected from unauthorized access, modification, and deletion.

How does the script define confidentiality in the context of cybersecurity?

Confidentiality in cybersecurity refers to the protection of information from unauthorized access, ensuring that private data remains secret and is not disclosed to unauthorized individuals.

What are some measures that can be taken to ensure the integrity of data?

Measures to ensure data integrity include using cryptography to protect data from unauthorized modification and implementing intrusion detection systems to monitor and prevent unauthorized actions that could compromise data integrity.

Why is availability important in cybersecurity?

Availability ensures that systems and data are accessible to authorized users whenever needed. Without availability, users cannot access the data they require, which can lead to significant operational disruptions.

What is the role of an incident response team in cybersecurity?

An incident response team is responsible for identifying the source of a security breach, containing the threat, recovering compromised data, and preventing further damage to minimize the impact of a cyber attack.

How does the script illustrate the practical application of cybersecurity through Wendy's story?

The script uses Wendy's story to show how a business can be targeted by hackers, the consequences of a security breach, and the importance of having a robust incident response plan to recover from such incidents and protect customer data.
