    Study Notes

    Introduction to Cybersecurity Operations

    • The presentation covers cybersecurity dangers, threat actors, and security operation centers (SOCs).

    Cybersecurity Threats & Dangers

    • 2023 saw a 72% increase in data breaches compared to 2021.
    • There were 2,365 cyberattacks in 2023, impacting 343,338,964 victims.
    • Data breaches cost approximately $4.88 million on average in 2024.
    • Email is the most common vector for malware, comprising about 35% in 2023.
    • Ninety-four percent of organizations reported email security incidents.
    • Business email compromises caused over $2.9 billion in losses in 2023.

    Cybersecurity Threats & Dangers - Singapore Context

    • Over 8 in 10 organizations in Singapore experience a cybersecurity incident annually.
    • Businesses experience cybersecurity incidents more frequently than other organizations.
    • The incidents affect businesses, resulting in disruption, data loss, and reputational damage (48%, 46%, and 43% respectively).
    • Non-profit organizations face similar impacts, including 60% data loss and 44% reputational damage.
    • The increasing use of technology increases the need for cybersecurity.

    Threat Actors

    • Cyberattacks originate from threat actors, which can be individuals or groups.
    • The root causes of cyberattacks are often driven by motivations including financial gain, trade secrets, and global politics.
    • Common threat actor types include amateurs (script kiddies), hacktivists (those protesting politically), financial motivated actors, and state-sponsored actors (paid by governments).

    Security Operations Center (SOC)

    • SOCs are designed to monitor and respond to cybersecurity incidents.
    • A typical SOC structure consists of levels of analysis. These are frontline analysts (Tier 1), incident responders (Tier 2), and threat hunters (Tier 3).
    • Tools like security information and event management (SIEM) platforms help with monitoring, aggregating, and analyzing logs.
    • Security orchestration, automation, and response (SOAR) platforms automate incident investigations and responses.

    Incident Response Lifecycle

    • The incident response process involves several phases: preparation, detection & analysis, containment, eradication & recovery, and post-incident activity.
    • Preparation involves ensuring the necessary tools and resources are available.
    • Detection & analysis involves identifying potential indicators from a variety of sources.
    • Containment, Eradication & Recovery involves isolating threats, and restoring systems.
    • Post Incident Activity involves learning and improving to prevent reoccurrences.
