- 6. www.infosectrain.com Explain the difference between a Firewall and an Intrusion Detection System (IDS). 7. Firewall Intrusion Detection System (IDS) Controls and manages incoming and outgoing network traf๏ฌc based on prede๏ฌned security rules. Monitors and analyzes network or system activities to detect signs of malicious behavior. Serves as a protective barrier between a secure internal network and potentially unsafe external networks. Analyzes network traf๏ฌc and alerts on suspicious activity but does not block traf๏ฌc. Can actively block or allow traf๏ฌc based on prede๏ฌned policies. Primarily focuses on detection and alerting but does not actively block traf๏ฌc by default. Operates at the network layer (IP addresses, ports, protocols). Analyzes traf๏ฌc at a more detailed level, including content and behavior. Often employs stateful inspection to track the state of active connections. May use signature-based detection, anomaly detection, or behavior analysis for monitoring.
- 7. www.infosectrain.com What are some of the best practices for securing cloud environments? Best practices for securing cloud environments include: 8. Strong Access Controls: Implement robust identity and access management. Patch Management: Keep all softwares and systems up-to-date. Secure APIs: Ensure secure and well-documented API con๏ฌgurations. Monitoring and Incident Response: Implement continuous monitoring and a robust incident response plan. Data Encryption: Use encryption for data at rest and in transit to safeguard sensitive information from unauthorized access. Regular Audits: Conduct frequent security audits and assessments to identify and remediate vulnerabilities and miscon๏ฌgurations. Compliance Adherence: Follow industry and regulatory compliance standards. Explain Vulnerability Assessment and Penetration Testing (VAPT). VAPT is a security testing process that combines vulnerability assessment to identify weaknesses and penetration testing to simulate attacks. It helps organizations understand and remediate potential security risks. 9.
- 8. What is the importance of Data Loss Prevention (DLP)? 10. DLP focuses on ensuring the security of sensitive data by preventing unauthorized access and transmission. By carefully monitoring, detecting, and preventing data leakage, DLP effectively mitigates the potential for data breaches. This invaluable tool ensures that organizations can uphold data integrity, maintain con๏ฌdentiality, and quickly meet regulatory requirements. www.infosectrain.com Explain the difference between a Firewall and an Intrusion Detection System (IDS). 11. Malware Ransomware A malicious software that harms or exploits computer systems or networks. A type of malware that encrypts ๏ฌles or systems, demanding a ransom for their release. Primarily focused on stealing data, disrupting operations, or taking control of the system. Primarily focused on encrypting ๏ฌles and demanding payment for their decryption. Include viruses, worms, trojans, spyware, adware, and other types of harmful software. Speci๏ฌcally designed to encrypt ๏ฌles or entire systems, rendering them inaccessible without a decryption key. Can be delivered via email attachments, malicious downloads, infected websites, or compromised software. Often spread through phishing emails, malicious attachments, infected websites, or exploit kits.
- 9. What is the importance of security patching? 12. Security patching is vital for protecting systems against known vulnerabilities. Regularly applying patches closes security gaps, preventing exploitation by malicious actors. Patch management enhances system resilience, minimizes the risk of cyberattacks, and ensures a strong defense against emerging cybersecurity threats. Explain the concept of penetration testing. 14. Penetration testing is a proactive security assessment method where skilled professionals simulate cyberattacks to identify system, network, or application vulnerabilities and assess the effectiveness of security controls. Organizations gain insights into weaknesses by emulating real-world attacks, allowing them to address and fortify their defenses. Penetration testing is a crucial method for enhancing overall cybersecurity and minimizing the risk of actual breaches. www.infosectrain.com What are some of the most common security vulnerabilities in web applications? Common vulnerabilities include SQL injection, Cross-site Scripting (XSS), Cross-site Request Forgery (CSRF), security miscon๏ฌgurations, and inadequate input validation. 13.
- 10. Describe the zero-trust security model. 15. The zero-trust security model is an approach that assumes no entity, internal or external, is inherently trusted. It mandates continuous veri๏ฌcation and strict access controls, ensuring security measures are applied consistently across all users, devices, and applications, no matter of their location or network status. How would you detect and respond to a data breach? 16. Detection involves monitoring for unusual activity or security alerts. The response includes isolating affected systems, investigating breaches, mitigating damage, and implementing security measures to prevent future incidents. www.infosectrain.com What is threat intelligence, and how can it be used to improve security? Threat intelligence involves gathering and analyzing data, trends, and indicators to identify potential cyber threats. It aids in understanding and anticipating cyber risks. By providing insights into attackersโ tactics and techniques, threat intelligence can help organizations enhance their security posture, proactively mitigate threats, and fortify defenses. Utilizing threat intelligence enables informed decision-making to protect against evolving and sophisticated cyber threats. 17.
