Cybersecurity Fundamentals - Part 1 - Information Security

Karthik opens a cybersecurity journey, sharing ten years of hands-on experience in network security, ethical hacking, and cryptography to help you understand and mitigate evolving threats.

Explore cybersecurity fundamentals across cyberspace, network, endpoint, and application security, with hands-on labs on firewalls, ids/ips technologies, malware analysis, phishing campaigns, and risk management.

Explore information security and its role in protecting an organization's data and continuity. Master the CIA triad—confidentiality, integrity, availability—and practical measures like encryption, access control, and backups.

Adopt a multidisciplinary approach to information security by combining IT, legal, HR, and finance expertise to protect assets, privacy, and regulatory compliance, not just an IT issue.

Explore key cybersecurity roles and responsibilities, from executive management to security professionals. Learn how asset owners, custodians, users, and auditors implement security policies to protect information assets.

Explore information security governance, aligning security with business objectives through policies, risk management, compliance, incident response, and awareness training to strengthen posture and culture.

Explore information security control frameworks, including ISO 27001, the NIST framework, and Corbett, to manage risk, access control, incident response, and governance of information assets.

Explore information security laws, regulations, and compliance to protect personal data and ensure organizations follow best practice for security; examine HIPAA, GDPR, and PCI DSS requirements, audits, and risk assessments.

Explore how information security policies, standards, procedures, and guidelines form a comprehensive framework that governs access control, data classification, data retention, disaster recovery, incident response, encryption, and network security.

Learn secure design principles to build systems that are secure by default. Apply least privilege, defense in depth, fail-safe defaults, economy of mechanism, and open design to reduce attack surfaces.

Change management identifies, documents, and assesses changes to information security systems, tests and implements them, and monitors outcomes to strengthen the organization's security posture and mitigate risk.

Identify vulnerabilities in software, hardware, and systems through proactive scanning and risk-based prioritization, then develop and deploy patches to mitigate threats and minimize downtime.

Conduct risk assessment and management by identifying risks, evaluating likelihood and impact, and developing plans, such as policies, procedures, technology, and training, to mitigate or avoid them.

Explore business continuity planning (BCP) to keep operations running during disruptions through data backup, recovery, alternative communication strategies, and contingency plans, with emphasis on testing and updates to minimize downtime.
