  2. What is cybersecurity?
  3. How can cybersecurity save an organization from cybercrime?

The Digital Era & Data Generation

  • Data stored on the cloud, accessible via multiple devices
  • Hackers exploit vulnerabilities, creating a variety of cyberthreats

Types of Cyber Attacks

  1. Malware: Malicious code (Trojans, viruses) stealing data or causing damage
  2. Phishing: Fraudulent emails requesting data via links
  3. Password Attacks: Cracking user passwords to gain system access
  4. DDoS (Distributed Denial of Service): Overloading a network with traffic
  5. Man-In-The-Middle: Intercepting communication between two parties
  6. Drive-By Downloads: Downloading malware by visiting compromised sites
  7. Malvertising: Malicious code from online ads
  8. Rogue Software: Malware posing as security software

Examples of Major Cyber Breaches

  • Companies like eBay, AOL, Evernote, Adobe have suffered breaches

What is Cybersecurity?

  • Protection against unauthorized data access, modification, or deletion
  • Ensures confidentiality, integrity, and availability (CIA Triad)
    • Confidentiality: Ensuring only authorized access to data
    • Integrity: Maintaining data accuracy and trustworthiness
    • Availability: Ensuring data accessibility and functionality

Methods of Protection

  • Identify: Recognize ongoing cyber threats
  • Analyze: Evaluate affected systems
  • Patch: Address vulnerabilities and restore operations

Key Concepts in Cybersecurity

  1. Vulnerability: Weakness allowing exploit
    • Regular testing and questions on backup, cloud security, antivirus, etc.
  2. Threat: Potential harm (natural, unintentional, intentional)
    • Stay informed on trends, perform regular assessments, penetration testing
  3. Risk: Potential loss or damage (financial, legal, privacy)
    • Assess risk, involve stakeholders, prioritize breach responses

Risk Management Strategy

  • Assess risks, determine needs, stakeholder involvement, develop plan

Cybersecurity Scenario

  • Importance of Automated Response Platforms (ARPs)
  • Example: Bob’s company using ARP
    • Detection of irregular activity
    • Locking accounts, patching vulnerabilities
    • Communication with legal departments
    • Fast incident containment and compliance notifications

Conclusion

  • Essential role of cybersecurity in the digital world
  • Importance of proactive and reactive measures
