Difference between IDS and IPS.

IDS vs. IPS: Unveiling the Key Differences in Network Security

Key Points:

  • **IDS (Intrusion Detection System):** Passively monitors network traffic for malicious activity.
  • **IPS (Intrusion Prevention System):** Actively monitors and blocks or mitigates malicious traffic.
  • **Key Difference:** IDS only detects threats; IPS detects *and* prevents them.

**IDS vs. IPS: A Detailed Comparison**

Feature IDS IPS
Primary Function Detects intrusions Detects and prevents intrusions
Response to Threats Generates alerts; requires manual intervention Blocks or mitigates threats automatically
Impact on Network Performance Minimal Can be higher due to active intervention
Deployment Inline or out-of-band Typically inline
False Positives Higher potential Higher potential, but mitigation actions reduce impact

What is architectural design? Discuss different style and patterns of architecture.

Mastering Software Architecture: Styles and Patterns What is Architectural Design? Blueprint for software systems. Defines structure, behavior, and interactions. Guides development, ensuring scalability and maintainability. Addresses high-level concerns, not implementation details. Impacts performance, security, and cost. Architectural Styles Layered Architecture: Organizes system into horizontal layers (presentation, business logic, data access). Microservices Architecture : Breaks down application into small, independent services. Event-Driven Architecture: Components communicate asynchronously via events. Space-Based Architecture: Distributes data and processing across geographical locations. Client-Server Architecture :** Classic model with clients requesting services from servers. Architectural Patterns Model-View-Controller (MVC):  Separates concerns into model (data), view (presentation), and controller (logic). Model-View-ViewModel (MVVM): Variation o...

State the need for software configuration review.

The Indispensable Software Configuration Review: Why It Matters Early Problem Detection Prevents costly late-stage bug fixes. Identifies inconsistencies early in the development lifecycle. Reduces integration challenges. Enhanced Collaboration Improves communication between development teams. Facilitates knowledge sharing among team members. Ensures everyone is on the same page regarding the software configuration. Improved Quality Assurance Helps meet compliance requirements. Reduces the risk of security vulnerabilities. Ensures software stability and reliability. Better Traceability and Auditability Simplifies future maintenance and updates. Provides clear documentation for compliance audits. Allows for easier rollback in case of errors. Reduced Risks Minimizes potential for configuration drift. Prevents deployment failures and downtime. Improves overall project success rate.

Define Engineering Ethics. Distinguish between ethics, laws and morals.

Navigating the Ethical Minefield: Engineering Ethics in IT Defining Engineering Ethics The study of moral issues and decisions confronting individuals and organizations engaged in engineering. Application of ethical principles to engineering practice, design, and research. Focus on responsible innovation, safety, and societal well-being in engineering projects. Consideration of potential impacts on stakeholders – users, environment, society. Ethics vs. Laws vs. Morals Ethics: Formal system of principles governing conduct; professional codes and guidelines. Laws: Societal rules enforced by governmental authority; legally binding requirements. Morals: Individual beliefs and values about right and wrong; personal sense of what is good/bad. Distinguishing the Three in IT Ethics:  IT professional codes (ACM, IEEE) specify confidentiality, data security, intellectual property respect. Laws:  Copyright laws, data privacy regulations (GDPR, CCPA), cybercrime statut...
