1. Preparation: Developing an incident response plan, training personnel, and ensuring the availability of necessary resources.
2. Identification: Detecting and recognizing the occurrence of a security incident.
3. Containment: Limiting the scope and impact of the incident to prevent further damage.
4. Eradication: Removing the cause of the incident and eliminating the threat.
5. Recovery: Restoring normal operations and recovering any lost data or systems.
6. Lessons Learned: Reviewing the incident response process, identifying areas for improvement, and updating the incident response plan accordingly.

12. How do you perform a risk assessment, and what are the common risk management strategies?

Risk assessment involves identifying, analyzing, and evaluating the potential risks and threats to an organization’s assets, systems, and operations.  The key steps in a risk assessment process include:

1. Asset identification: Identifying the critical assets that need to be protected.
2. Threat identification: Identifying the potential threats (e.g., cyber attacks, natural disasters, human errors) that could impact the assets.
3. Vulnerability assessment: Evaluating the weaknesses or gaps in the organization’s security controls.
4. Risk analysis: Determining the likelihood and impact of the identified threats and vulnerabilities.
5. Risk evaluation: Prioritizing the risks based on their severity and likelihood.

Common risk management strategies include:

1. Risk avoidance: Eliminating the risk by avoiding the activity or asset that poses the risk.
2. Risk mitigation: Implementing security controls and measures to reduce the likelihood or impact of the risk.
3. Risk transfer: Transferring the risk to a third party, such as through insurance or outsourcing.
4. Risk acceptance: Acknowledging the risk and deciding to accept it based on the organization’s risk tolerance.

13. What is the role of security policies and procedures in an organization?

Security policies define the organization’s overall security objectives, guidelines, and requirements for protecting its assets and information.
Security procedures provide detailed, step-by-step instructions on how to implement and enforce the security policies.  The key roles of security policies and procedures in an organization include:

• Establishing a clear and consistent approach to security management
• Defining roles, responsibilities, and accountability for security-related activities
• Ensuring compliance with relevant laws, regulations, and industry standards
• Guiding the implementation and maintenance of security controls and measures
• Providing a framework for incident response, business continuity, and disaster recovery
• Promoting security awareness and training among employees

14. How do you ensure business continuity and disaster recovery in the event of a cyber incident?

Business continuity planning involves identifying critical business functions, processes, and resources, and developing strategies to maintain operations during and after a disruptive event.
Disaster recovery planning focuses on the restoration of IT systems, data, and infrastructure in the event of a disaster, such as a cyber attack, natural disaster, or system failure.
Key elements of a robust business continuity and disaster recovery plan include:

• Identifying and prioritizing critical business functions and IT systems
• Implementing redundancy and backup mechanisms for data and systems
• Establishing alternative communication and collaboration channels
• Defining clear roles, responsibilities, and communication protocols
• Regularly testing and updating the plan to ensure its effectiveness

15. Providing employee training and awareness on emergency procedures

What are the common compliance frameworks and regulations in the cybersecurity domain?
GDPR (General Data Protection Regulation): A comprehensive data privacy and security regulation in the European Union.
HIPAA (Health Insurance Portability and Accountability Act): Establishes standards for the protection of electronic protected health information (ePHI) in the healthcare industry.
PCI DSS (Payment Card Industry Data Security Standard): Mandates security requirements for organizations that handle credit card transactions.
NIST (National Institute of Standards and Technology) Cybersecurity Framework: A voluntary framework that provides a common language and approach for managing cybersecurity risk.
FISMA (Federal Information Security Management Act): Requires federal agencies to develop, document, and implement an information security program.
ISO/IEC 27001: An international standard that specifies the requirements for an information security management system (ISMS).

Ethical Hacking and Penetration Testing

16. What is the purpose of ethical hacking, and what are the common techniques used?

Ethical hacking, also known as penetration testing or white hat hacking, is the practice of simulating cyber attacks to identify and address security vulnerabilities in an organization’s systems and networks.
The primary purpose of ethical hacking is to proactively assess an organization’s security posture, uncover potential weaknesses, and provide recommendations for improving the overall security.
Common ethical hacking techniques include:

1. Reconnaissance: Gathering information about the target, such as network topology, open ports, and running services.
2. Vulnerability scanning: Identifying and cataloging vulnerabilities in the target systems and applications.
3. Exploitation: Attempting to exploit the identified vulnerabilities to gain unauthorized access or control.
4. Post-exploitation: Expanding the attacker’s foothold within the target environment and gathering additional information.
5. Reporting and remediation: Documenting the findings and providing recommendations for addressing the identified security issues.

17. Explain the different phases of a penetration testing engagement.

• Planning and Reconnaissance: Gathering information about the target organization, its systems, and its security controls.
• Vulnerability Identification: Scanning the target environment to identify potential vulnerabilities and weaknesses.
• Exploitation: Attempting to exploit the identified vulnerabilities to gain access to the target systems or networks.
• Post-Exploitation: Expanding the attacker’s foothold within the target environment and gathering additional information or access.
• Reporting and Remediation: Documenting the findings, analyzing the impact, and providing recommendations for addressing the identified security issues.

What is the difference between vulnerability scanning and penetration testing?

Vulnerability scanning is the process of identifying and cataloging known vulnerabilities in an organization’s systems, networks, and applications.
Penetration testing, on the other hand, involves actively attempting to exploit the identified vulnerabilities to gain unauthorized access or control over the target environment.
Vulnerability scanning is a more automated and less intrusive process, while penetration testing is a more comprehensive and hands-on approach that simulates real-world cyber attacks.
Vulnerability scanning provides a broad overview of potential security weaknesses, while penetration testing focuses on the actual impact and exploitability of those vulnerabilities.
Vulnerability scanning is often a precursor to penetration testing, as the findings from the vulnerability scan can be used to guide and inform the penetration testing activities.

How do you perform network reconnaissance and footprinting?

Network reconnaissance involves gathering information about the target network, its topology, and its components.
Footprinting is the process of collecting information about an organization, its systems, and its online presence, which can be used to plan and execute a cyber attack.
Common techniques for network reconnaissance and footprinting include:

• DNS enumeration: Gathering information about the target’s domain name system (DNS) records.
• Port scanning: Identifying open ports and running services on the target systems.
• Whois lookup: Obtaining information about the ownership and registration of a domain.
• Social media and online research: Gathering publicly available information about the target organization and its employees.
• Passive information gathering: Collecting data without directly interacting with the target, such as through search engine queries or traffic monitoring.

What are the common tools used in ethical hacking and penetration testing?

• Nmap (Network Mapper): A powerful network scanning and discovery tool.
• Metasploit Framework: A comprehensive platform for developing, testing, and executing exploit code.
• Wireshark: A network protocol analyzer used for packet capture and analysis.
• Burp Suite: A web application security testing suite that includes tools for proxy, scanner, and vulnerability analysis.
• Kali Linux: A Linux distribution specifically designed for penetration testing and ethical hacking.
• John the Ripper: A password cracking tool used to identify weak or compromised passwords.
• Sqlmap: An open-source tool used to detect and exploit SQL injection vulnerabilities.
• Maltego: A tool for gathering and visualizing information about a target, including social networks and online presence.

Remember, these are just a few examples of the many tools and techniques used in ethical hacking and penetration testing. The specific tools and methods employed will depend on the scope and objectives of the engagement, as well as the target environment and the security controls in place.
