Study Notes
Security+ 701 - Overview
- Security+ 701 is a foundational certification exam covering a broad range of security concepts.
- It emphasizes practical application of security principles rather than theoretical knowledge.
- Candidates should be familiar with a wide range of security domains and best practices.
Access Control
- Access control mechanisms are critical for protecting sensitive information.
- They regulate who can access specific resources (data, systems, networks).
- Basic access control models include:
- Mandatory Access Control (MAC): Access is based on security labels, with strict enforcement determined by a security administrator.
- Discretionary Access Control (DAC): Access permissions are granted by the object owner or administrator, allowing for more flexibility.
- Role-Based Access Control (RBAC): Access rights are based on defined roles, ensuring that users can perform only necessary actions.
Cryptography
- Cryptography is the science of using codes to protect data.
- Key concepts include:
- Encryption: Transforming plaintext into ciphertext.
- Decryption: Transforming ciphertext into plaintext.
- Hashing: Creating a one-way function to calculate a unique digital fingerprint of data.
- Digital signatures: Ensuring data integrity and authenticity using public-key cryptography.
- Symmetric-key encryption: Use of the same key for encryption and decryption.
- Asymmetric-key encryption: Use of different keys for encryption and decryption.
- Common cryptographic algorithms and protocols (e.g., AES, RSA, SHA-256, TLS) are essential knowledge.
Network Security
- Protecting network infrastructure is essential for securing an organization's assets.
- Essential network security concepts include firewalls, intrusion detection systems (IDSs), and intrusion prevention systems (IPSs).
- Understanding network topologies, protocols, and vulnerabilities is paramount.
- Common network protocols and their security implications (e.g., TCP/IP, HTTP, HTTPS) need to be understood.
Security Threats and Vulnerabilities
- Understanding common threats and vulnerabilities is key to developing effective security controls.
- Common threats and attack vectors include:
- Malware: Viruses, Trojans, worms, ransomware.
- Phishing: Social engineering attacks tricking users into revealing sensitive information.
- Denial-of-Service (DoS) attacks: Flooding a system with traffic to disrupt service.
- Man-in-the-middle (MitM) attacks: Intercepting communications between two parties.
Security Architecture and Design
- Proper security architecture is fundamental to an effective security posture.
- A robust security strategy should encompass policies, procedures, and technologies.
- It is important to identify assets, develop secure configurations, and address vulnerabilities.
- Implementing multi-factor authentication is a best practice for enhancing security.
Physical Security
- Physical security involves protecting hardware, infrastructure, and facilities.
- Controls include access restrictions, environmental controls, and asset tracking/inventory management.
- Employee training regarding physical security is crucial.
Security Operations and Monitoring
- Security operations encompass the processes of detecting, responding to, and recovering from security incidents.
- Log management, security information and event management (SIEM), intrusion detection/prevention systems (IDS/IPS) are essential components.
- Monitoring security systems for anomalies and suspicious activity is vital.
Disaster Recovery and Business Continuity
- Disaster recovery and business continuity plans are crucial for ensuring an organization can withstand disruptions.
- These plans should cover potential disasters, recovery strategies, and communication protocols.
- Data backup and recovery procedures should be tested and regularly updated.
Policies and Procedures
- Security policies and procedures provide the framework for implementing security controls.
- Developing, reviewing, and maintaining these policies are critical for an effective security program.
- Employee training on security policies is important for compliance and best practices.
Identity and Access Management (IAM)
- Identity and access management (IAM) controls who has access to what resources.
- It involves managing identities, authentication, authorization, and access.
- Protecting user accounts and credentials is essential.
Legal and Regulatory Compliance
- Understanding legal and regulatory requirements in a given context is key to compliance.
- Different jurisdictions have different legal and regulatory requirements that impact security and compliance.
- Understanding relevant regulations like HIPAA, PCI DSS, GDPR is important to avoid violations.
