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.
