Study Notes

Overview of Security Operations Center (SOC)

SOC develops the organization's incident response plan, detailing activities, roles, responsibilities, and success metrics for incident management.
Regular testing includes vulnerability assessments and penetration tests to identify weaknesses and simulate attacks, leading to updated security policies and response plans.
SOC keeps abreast of the latest security solutions and emerging threats through intelligence gathered from sources like social media and the dark web.
Continuous monitoring of the IT infrastructure occurs 24/7 to detect known exploits and suspicious activities.
Log management is essential for tracking network events; analyzing logs helps establish norms and spot anomalies.
Threat detection involves filtering real threats from false positives, with modern SIEM solutions using AI for improved threat identification.
In incident response, SOC takes immediate actions to limit damage, which may include investigating root causes, isolating affected systems, and running protective software.
Recovery efforts focus on eradicating threats, restoring affected systems, and resetting credentials post-incident.
Post-mortem analysis allows for vulnerability assessment and updates to incident response plans based on lessons learned.
Compliance management ensures adherence to data privacy regulations (e.g., GDPR, HIPAA) and mandates proper incident reporting and data retention.

Importance of the SOC

SOC enhances asset protection by reducing unauthorized access and threats to sensitive data.
Business continuity is maintained through minimized security incidents and disruptions.
Regulatory compliance is supported by documenting incidents and maintaining security measures.
Cost savings come from preventing breaches, with initial SOC investments often lower than the financial damages of incidents.
Customer trust is built through robust cybersecurity measures, fostering confidence in organizational integrity.
Enhanced incident response capabilities limit downtime and promote quick recovery from incidents.
Improved risk management stems from proactive identification of vulnerabilities based on security event analysis.

SOC Roles and Responsibilities

SOC manager oversees the team, ensuring coordination and reporting to the Chief Information Security Officer (CISO).
Security engineers focus on building and managing security architecture, including evaluating and implementing security tools.
Security analysts act as first responders, detecting and investigating threats, and mitigating their impacts. Roles may vary in complexity (Tier 1 vs. Tier 2).
Threat hunters specialize in identifying advanced threats that evade automated security measures.

Introduction to Cyber Threats

Cyber threats encompass malicious attempts to compromise information system integrity, confidentiality, or availability from various actors.

Types of Cyber Threats

Malware includes harmful software like viruses and ransomware aimed at damaging systems.
Phishing involves fraudulent attempts to acquire sensitive data by masquerading as trusted entities.
Denial of Service (DoS) attacks render systems unavailable; Distributed DoS (DDoS) uses multiple systems to overwhelm a target.
Man-in-the-Middle (MitM) attacks intercept communication between parties.
SQL Injection exploits software vulnerabilities by inserting harmful SQL code.
Zero-Day Exploits target newly discovered vulnerabilities before fixes are released.
Advanced Persistent Threats (APTs) are prolonged attacks that allow intruders to remain undetected on networks.

Attack Vectors

Attack vectors are methods cybercriminals employ to infiltrate systems.
Social engineering manipulates individuals into divulging confidential information.
Credential theft involves acquiring usernames and passwords for unauthorized access.
Vulnerability exploits take advantage of software or hardware flaws to gain access.

Malware vs. Phishing

Malware is malicious software designed for damage, while phishing is a social engineering tactic to obtain information.
Malware impacts system integrity directly, while phishing threatens user information and trust.

Advanced Persistent Threats (APTs)

APTs represent targeted, stealthy attacks that can go undetected for extended periods, posing unique challenges for SOCs due to their complexity and sophistication.
