Introduction to Cybersecurity

Introduction to Cybersecurity

• Cybersecurity protects systems, networks, and data from cyber threats.
• Understanding cybersecurity concepts is crucial for safeguarding organizational assets.

Key Cybersecurity Principles

• Confidentiality: Ensures sensitive information is accessible only to authorized individuals.
• Integrity: Protects data accuracy and completeness, preventing unauthorized alterations.
• Availability: Guarantees access to information and resources for authorized users.

Cyber Threats and Vulnerabilities

• Cyber threats exploit vulnerabilities in a system, posing potential danger.
• Common Cyber Threats:
  • Phishing: Attackers impersonate legitimate entities to trick users into revealing sensitive information.
  • Social Engineering: Uses psychological manipulation to extract confidential information.

Understanding Vulnerabilities

• A vulnerability is a weakness in a system that cyber threats can exploit.
• Organizations must regularly assess vulnerabilities and address them. 

Consequences of Cyber Breaches

• Financial Consequences:
  • Direct Financial Losses: Includes theft of funds, fraud, and breach mitigation costs.
  • Legal Penalties: Fines and penalties for non-compliance with security regulations.
• Reputational Damage: Loss of customer trust, negatively impacting reputation and customer relationships.
• Operational Disruption: Disrupted business operations, leading to downtime and reduced productivity.

Risk Management in Cybersecurity

• Risk management systematically identifies, assesses, and mitigates cyber threats.
• Key Steps in Risk Management:
  • Identifying Assets, Threats, and Vulnerabilities: Recognizing assets needing protection and understanding threats and vulnerabilities.
  • Conducting Risk Assessments: Regularly evaluating the likelihood and potential impact of risks.
• Risk Management Strategies:
  • Risk Avoidance: Eliminating risky activities or processes.
  • Risk Transference: Shifting risk to a third party (e.g., insurance).
  • Risk Acceptance: Accepting certain risks when mitigation costs exceed potential losses.
  • Risk Mitigation: Implementing controls to reduce risk likelihood or impact.

Implementing Security Controls

• Technical Controls:
  • Firewalls: Act as barriers between internal and external networks, filtering traffic.
  • Encryption: Converts data into a secure format readable only with a decryption key.
• Administrative Controls:
  • Security Policies: Establishing clear policies for data access and usage.
  • Security Training: Providing employees with awareness programs to identify and respond to potential threats.
• Physical Controls:
  • Access Control Measures: Using keycard access to restrict physical access to assets.

Continuous Monitoring and Updating

• Cybersecurity requires ongoing monitoring and updates to risk management plans.
• Regular reviews ensure:
  • Adaptation to evolving threats and vulnerabilities.
  • Effectiveness and relevance of risk management strategies.

Vendor and Third-Party Risk Management

• Organizations must assess risks associated with third-party vendors.
