Study Notes
Information Security Policy, Standards, and Practices
- Organization: A group of people working towards a common goal, with defined acceptable behaviors.
- Policy: Management's intentions communicated to employees, outlining desired security practices.
- Effective Security Program: Formal plan to implement and manage security within an organization.
- Issue-Specific Security Policy (ISSP): Addresses specific technology areas, requiring frequent updates and organizational position statements.
- Systems-Specific Policy (SYSSP): Detailed technical specifications guiding implementation and configuration of a specific technology.
- Policy: Set of guidelines/instructions implemented by senior management.
- Standards: Detailed descriptions of compliance with policy, outlining specifics and procedures.
- Procedures: Methods for accomplishing policies and standards.
- Effective Policies: Include dissemination, comprehension, compliance, and uniform enforcement.
What Drives Policy Development?
- Mission: Written statement of purpose, usually not modified.
- Vision: Written statement of long-term goals, sometimes modified.
- Strategic Planning: Process for moving the organization toward its vision, constantly reworked.
- Security Policy: Set of rules protecting organizational assets.
Types of Information Security Policies
- Information Security Policy: Set of rules protecting organizational information assets.
- Enterprise Information Security Policies: General security policies.
- Issue-Specific Security Policies: Specific technology policies.
- Systems-Specific Security Policies: Configurations of systems.
Access Control List (ACL)
- ACL: A defined set of rules (often abbreviated as ACL).
- Types of ACLs:
- Standard ACLs: Fundamental packet filtering.
- Extended ACLs: More granular control than standard ACLs.
- Dynamic ACLs (lock-and-key): Allow IP packet returns to the sender.
- Reflexive ACLs: Allow IP packet returns to the sender.
- Time-based ACLs: Limit access to a network/device based on time of day/week.
Week 11: Planning for Security P2
- The Five Pillars of NIST:
- Identify: Inventory of IT assets & vulnerabilities.
- Protect: Measures like MFA and phishing training.
- Detect: Setup of monitoring solutions (SIEM, IDS).
- Respond: Automated incident flagging & ticketing.
- Recover: Time to restore functionality and attack response procedures.
Week 12: Security Technology: Intrusion Detection, Access Control, and Other Security Tools
- Intrusions: Malicious attempts to disrupt or break into a system.
- Intrusion Detection: Procedures/systems for detecting system intrusions.
- Intrusion Reaction: Actions taken upon detecting an intrusion.
- Intrusion Correction: Activities to restore normal operations.
- Intrusion Prevention: Actions to deter intrusions proactively.
- NIDS: Network Intrusion Detection Systems: resides on a network segment to detect attacks.
- NIDS Advantages/Disadvantages:
- Advantages: Monitor large networks with fewer devices, passively deployed, less susceptible to attacks.
- Disadvantages: Can be overwhelmed by network traffic, need to monitor all traffic, cannot analyze encrypted packets or detect some attacks like fragmented packets.
Week 13: Cryptography
- Cryptography: Secret writing for secure communication.
- Cryptology: Science of secure comms.
- Cryptanalysis: Science of breaking encrypted comms.
- Cipher: Cryptographic algorithm.
- Unencrypted Message (plaintext).
- Encryption: Converts plaintext to ciphertext.
- Decryption: Converts ciphertext to plaintext.
- Cryptographic Hash Function: Mathematical function for integrity checks and authentication.
- Hash Functions: Common data structures for message integrity and authentication.
Week 14: Cryptography P2
- Digital Certificate: Electronically verifies a device, server, or user's identity using cryptography and PKI.
- Secure Sockets Layer (SSL): Verifies website identity to web browsers.
- Types of Public Key Certificates:
- TLS/SSL (server-client comms).
- Domain Validated.
- Organization Validated.
- Extended Validation.
- Collision-Free: No two input hashes should produce the same output hash.
- Examples of Cryptographic Hash Functions: Password verification, signature verification, and integrity verification.
Week 15: Physical Security
- Physical Security: Protects personnel, hardware, software, networks, and data from physical threats.
- Major Sources of Physical Loss: Extreme temp, gases, liquids, living organisms, projectiles, movement, energy anomalies, radiation.
- Security Controls: Implemented parameters to protect data and infrastructure.
- Types of Security Controls: Physical, Digital, Cybersecurity, Cloud Security.
Week 16: Implementing Information Security
- Major steps in executing project plan: Planning, supervising tasks, wrapping up.
- Project Planning Considerations: Financial, priority, time, schedule, staff, procurement, organizational feasibility, and training.
- Organizational Feasibility Considerations: Policies, technology, training, scope.
- The Need for Project Management: Specialized skills and broad understanding necessary.
- Technical Topics of Implementation: Technical and human interface aspects.
- Conversion Strategies: Four basic approaches (direct, phased, pilot, parallel).
- The Bull's-Eye Model for Information Security Project Planning: Prioritizing complex changes systematically.
To Outsource or Not, Technology Governance, and Organizational Change
- Outsourcing IT/Information Security: Consideration for complex nature of outsourcing, best vendor/attorneys recommended.
- Technology Governance & Change Control: Managing impact and costs from technology implementation.
- Change Control Considerations: Communication, coordination, unintended consequences, quality of service, and compliance.
- Organization Change Considerations: Steps for organizational change, reducing resistance and developing supporting cultures.
