- What is a VPN, and why is it important?
- A VPN, or Virtual Private Network, creates a secure, encrypted connection crucial for safeguarding data transmitted over the internet, ensuring privacy and security.
- Explain the concept of a firewall and its role in cybersecurity.
- A firewall monitors and controls incoming and outgoing network traffic based on predetermined security rules, acting as a barrier between secure internal networks and untrusted external networks.
- What is the difference between IDS and IPS?
- An Intrusion Detection System (IDS) detects potential security breaches, while an Intrusion Prevention System (IPS) actively blocks and mitigates those threats.
- Define encryption and the types of encryption.
- Encryption converts data into a coded format to prevent unauthorized access. Symmetric encryption uses one key for encryption and decryption, while asymmetric encryption uses a public-private key pair.
- Describe the role of encryption in cybersecurity.
- Encryption protects data confidentiality, ensures data integrity, and verifies authentication, securing information during transmission and storage.
- What is a security risk assessment, and why is it important?
- It identifies, evaluates, and implements critical security controls for recognizing vulnerabilities and preventing unauthorized access.
- What are the main differences between symmetric and asymmetric encryption?
- Symmetric encryption uses one key for encryption and decryption, whereas asymmetric encryption uses a public key for encryption and a private key for decryption.
- Explain the difference between a virus and a worm.
- A virus requires user interaction to spread, while a worm is self-replicating and spreads independently, exploiting network vulnerabilities.
- What is phishing, and how can it be prevented?
- Phishing is a deceptive attempt to obtain sensitive information, preventable through user education, spam filters, and robust authentication methods.
- What is a DDoS attack, and how can it be mitigated?
- A Distributed Denial of Service attack overwhelms a system with traffic to cause downtime, mitigated by anti-DDoS tools, rate limiting, and redundant network resources.
- What is social engineering, and provide an example.
- It’s the manipulation to obtain confidential information. An example is baiting, where attackers use false promises to pique a victim’s greed or curiosity.
- Describe what a honeypot in cybersecurity is.
- A honeypot is a decoy system designed to attract and trap attackers, used to study attack strategies and strengthen security.
- Explain the concept of ‘zero trust’ in cybersecurity.
- Zero trust is a security model that requires all users, whether inside or outside the organization’s network, to be authenticated and authorized before accessing data.
- What is the principle of least privilege, and why is it important?
- It ensures users have only the access necessary to perform their tasks, minimizing the potential for unauthorized access or damage.
- What is a man-in-the-middle attack, and how can it be prevented?
- It’s an attack where the perpetrator intercepts communication between two parties to steal or manipulate data, which is preventable using encryption and secure protocols.
- How do you differentiate between risk, threat, and vulnerability in cybersecurity?
- Risk is the potential for damage when a threat exploits a vulnerability. A threat is a potential cause of an incident, while a vulnerability is a weakness that can be exploited.
- What is the function of a Security Operations Center (SOC)?
- A SOC monitors, detects, analyzes, and responds to cybersecurity incidents, using integrated security solutions to protect against threats.
- Discuss the concept of ‘defense in depth’ in cybersecurity.
- It’s a layered security approach that uses multiple security measures to protect information, ensuring that if one defense layer fails, others still provide protection.
- What is the significance of an incident response plan in cybersecurity?
- It provides a structured approach for handling security incidents, ensuring effective and timely responses to minimize impact and restore operations.
- Explain what a botnet is and why it’s a concern.
- A botnet is a network of infected computers controlled by an attacker, used for large-scale attacks or fraud, posing significant security and operational risks.
- How do you ensure data confidentiality, integrity, and availability?
- By implementing encryption for confidentiality, checksums for integrity, backups, and redundancy for availability.
- What are the common types of cyber attacks?
- They include malware, phishing, ransomware, man-in-the-middle attacks, and SQL injection, each with unique tactics and impacts.
- What is two-factor authentication, and why is it important?
- It’s a security process where users provide two different authentication factors, significantly enhancing security by adding an extra layer of verification.
- Describe the process of a penetration test.
- Penetration testing simulates an attack on a system to identify vulnerabilities and assess the effectiveness of security measures involving planning, surveillance, exploitation, and reporting.
- What is the difference between vulnerability scanning and penetration testing?
- Vulnerability scanning is an automated process to identify potential vulnerabilities, while penetration testing is a manual, in-depth examination to exploit weaknesses.
- How do you handle a detected intrusion?
- Follow the incident response plan: isolate the system, analyze the breach, contain and eradicate the threat, recover the system, and document the incident.
- What are the common indicators of a compromised system?
- Indicators include unusual system behavior, unexpected software installations, excessive network traffic, and unauthorized user activities.
- How can organizations prevent data leaks?
- Organizations can prevent unauthorized data access and leaks through data encryption, access controls, employee training, and monitoring and controlling data transfer.
- What is the importance of asset management in cybersecurity?
- It helps identify and manage organizational assets, ensuring security controls are applied, and vulnerabilities are managed across all assets.
- Explain what is meant by ‘chain of custody’ in digital forensics.
- It refers to the documentation that records evidence handling, ensuring its integrity and authenticity from collection to presentation in court.
- How do you ensure secure coding practices?
- I adhere to coding standards, conduct code reviews, use automated code analysis tools, and implement security testing throughout the development lifecycle.
- What is an SSL certificate, and why is it important?
- An SSL certificate authenticates a website’s identity and enables an encrypted connection, crucial for ensuring data security and user trust online.
- What is digital forensics, and what are its key stages?
- Digital forensics involves collecting and analyzing electronic data to recover and investigate material found in digital devices, including collection, examination, analysis, and reporting.
- What are the different types of security models, and how do they differ?
- Security models like DAC, MAC, and RBAC differ in how they manage access and control; DAC allows owners to set policies, MAC enforces policies based on classification, and RBAC assigns rights based on roles.
- How do you manage passwords securely in an organization?
- Organizations can secure user credentials effectively by enforcing strong password policies, using password managers, and implementing regular changes and multi-factor authentication.
- What is patch management, and why is it important?
- Patch management is managing software and systems updates, crucial for fixing vulnerabilities, enhancing functionality, and protecting against threats.
