Questions and Answers

How does the principle of 'least privilege' contribute to enhancing cybersecurity within an organization?

By limiting access rights to the minimum necessary for users to perform their job functions, the principle of least privilege reduces the potential damage from insider threats and malware.

Explain the difference between authentication and authorization in the context of cybersecurity.

Authentication verifies the identity of a user, device, or system, while authorization determines what an authenticated user is allowed to access or do.

Describe how a Security Information and Event Management (SIEM) system enhances an organization's ability to respond to cyber threats.

SIEM systems aggregate and analyze security logs and events from various sources, providing real-time threat detection, incident analysis, and compliance reporting.

What are the key differences between a Virus and a Worm, and why is understanding these differences important for cybersecurity?

Viruses require a host file to spread, whereas worms are standalone and self-replicating. Knowing the difference helps in choosing appropriate prevention and mitigation strategies. Signup and view all the answers

How does endpoint detection and response (EDR) differ from traditional antivirus software, and why is this difference important in modern cybersecurity strategies?

Traditional antivirus software focuses on prevention and detection of known malware, while EDR provides continuous monitoring and response capabilities for a wider range of threats, including advanced and unknown malware. Signup and view all the answers

Describe how multi-factor authentication (MFA) strengthens security compared to single-factor authentication.

MFA requires users to provide multiple verification factors, such as a password and a code from a mobile device, making it significantly harder for attackers to gain unauthorized access, even if they have stolen a password. Signup and view all the answers

Explain how a VPN (Virtual Private Network) helps protect data transmitted over the internet.

A VPN creates an encrypted tunnel for data transmission, protecting it from eavesdropping and interception by encrypting the data and masking the user's IP address. Signup and view all the answers

How does the concept of 'non-repudiation' support cybersecurity and accountability?

Non-repudiation ensures that actions performed by a user can be traced and cannot be denied later. This supports accountability and aids in incident investigation. Signup and view all the answers

Describe how the OWASP (Open Web Application Security Project) Top Ten list can help organizations improve their web application security.

The OWASP Top Ten identifies the most critical web application security risks, providing developers and security professionals with a prioritized list of vulnerabilities to address and mitigate. Signup and view all the answers

Discuss the importance of patch management in maintaining a secure IT environment.

Patch management involves regularly updating software and systems with security patches to fix known vulnerabilities, thereby reducing the risk of exploitation by attackers. Signup and view all the answers
