  • Introduction to CompTIA Security+ SY0-701

    • Security is a critical concern in IT
    • Focus: network security, vulnerabilities, threats, etc.
    • Exam: 90 minutes, mix of multiple-choice and performance-based questions

  • Exam Structure Breakdown

    • 1.0 General Security Concepts: 12%
    • 2.0 Threats, Vulnerabilities, and Mitigations: 22%
    • 3.0 Security Architecture: 18%
    • 4.0 Security Operations: 28%
    • 5.0 Security Program Management and Oversight: 20%

  • 1.1 Security Controls

    • Security Risks: Vary based on asset type (data, physical property, systems)
    • Control Categories:
    • Technical Controls: Firewalls, anti-virus
    • Managerial Controls: Policies, procedures
    • Operational Controls: Physical security measures
    • Physical Controls: Barriers, locks, guards
    • Control Types:
    • Preventive: Block access
    • Deterrent: Discourage intrusions
    • Detective: Identify breaches
    • Corrective: Recovery measures
    • Compensating: Additional means to mitigate risks
    • Directive: Guidance towards compliance

  • 1.2 The CIA Triad

    • Confidentiality: Prevent unauthorized access
    • Integrity: Ensure data remains unaltered
    • Availability: Ensure data access when needed
    • Non-repudiation: Assurance that someone cannot deny the validity of their signature on a document
    • Managing Security Controls: Continuous assessment and adjustment needed as systems evolve

  • 1.3 Change Management

    • Change Management Importance: Enhances security but often challenging
    • Process Steps:
    • Define the change
    • Assess risk
    • Approvals
    • Notify affected users
    • Documentation: Keeping precise records of changes is crucial

  • 1.4 Public Key Infrastructure (PKI)

    • Critical for managing digital certificates
    • Key Types:
    • Symmetric: Single shared key (fast but harder to manage)
    • Asymmetric: Public and private keys (more secure)
    • Key Escrow: Legal access to decryption keys via third parties

  • 2.0 Threats and Vulnerabilities

    • Threat Actors: Internal vs. external, sophisticated vs. unsophisticated attackers
    • Common Threats: Phishing, malware, etc.

  • 2.1 Threat Vectors

    • Various methods attackers utilize to gain access
    • Understanding vectors helps build effective defenses

  • 2.3 Malware Types

    • Categories include: Ransomware, Worms, Trojans, etc.
    • Preventive Strategies: Backup data, keep systems updated

  • 4.1 Secure Baselines

    • Establish baselines for security: firewalls, application usage, etc.
    • Testing and Auditing Procedures: Regular audits of changes necessary

  • 5.1 Security Policies

    • Ensure comprehensive policies are documented: usage policies, change management, incident response, etc.
    • Compliance with Regulations: HIPAA, PCI-DSS impacts on security policies

  • 5.4 Compliance and Privacy

    • Identify and adhere to varying compliance standards to protect sensitive data
    • Document privacy policies for user data protection.

  • Security Awareness and User Training

    • Regular training for users on security risks like phishing, social engineering
    • Create a culture of security awareness within an organization.

  • Incident Response

    • Prepare for incidents with detailed plans
    • Follow NIST incident response guidelines to manage and minimize the impacts of security breaches.
