1. What Is Cybersecurity and Why Is It Important?
Ans:
Cybersecurity is the process of guarding against unwanted access, attacks or harm to computers, networks and private information. By avoiding data breaches, monetary losses and preserving faith in digital systems, it guarantees security for both people and businesses.
2. How Are IDS and IPS Different?
Ans:
An Intrusion Detection System (IDS) monitors network traffic and raises alerts when suspicious activity is found. An Intrusion Prevention System (IPS) goes further by actively blocking threats in real-time to stop attacks before they can cause harm.
3. What Are Common Types of Cyber Threats?
Ans:
Phishing, malware, ransomware, DDoS assaults, SQL injections and man-in-the-middle attacks are examples of cyberthreats. Phishing, for example, is the practice of tricking consumers into divulging passwords or other information through misleading emails.
4. Which Measures Can Keep a Network Secure?
Ans:
Network protection involves firewalls, IDS/IPS systems, VPNs, antivirus programs, strong access controls, frequent system updates and ongoing monitoring. These practices help prevent unauthorized entry and minimize the risk of breaches.
5. How Does Encryption Work and What Are Its Main Types?
Ans:
Through the conversion of readable material into a coded format, encryption stops unauthorized access. Symmetric encryption employs a single key for all operations, in contrast to asymmetric encryption which uses public key to encrypt the data and secret key to decrypt it.
6. How Do Vulnerability Assessment and Penetration Testing Differ?
Ans:
Vulnerability assessment identifies system weaknesses without exploiting them. Penetration testing actively exploits those weaknesses to simulate real attacks. Both approaches help strengthen overall security and identify areas for improvement.
7. How Can Professionals Keep Up With Cybersecurity Threats?
Ans:
Staying informed requires following security blogs, threat intelligence feeds, webinars, professional communities, certifications and research reports. This helps track emerging vulnerabilities and stay prepared against new types of cyberattacks.
8. What Is Multi-Factor Authentication and Why Is It Important?
Ans:
Multi-factor authentication (MFA) verifies identity using two or more methods, such as passwords, one-time codes or biometric data like fingerprints and facial recognition. MFA lowers risks even in the event that credentials are hacked since it provides an additional degree of security.
9. How Should a Ransomware Incident Be Managed?
Ans:
In a ransomware attack, affected systems should be immediately isolated to prevent further infection. Data should be restored from secure backups, attack methods analyzed, defenses updated, monitoring enhanced and staff trained to avoid future incidents.
10. Can You Give an Example of a Major Cybersecurity Incident?
Ans:
The SolarWinds attack is a significant example, where hackers exploited vulnerabilities in supply chain software to access multiple organizations. Effective mitigation included patching, continuous monitoring and threat detection to reduce risk and prevent similar breaches.
