IT Security

Watch the presentation What is Defense in Depth? Defense in Depth (DiD) is a cybersecurity strategy that employs multiple layers of security to protect data, systems, and networks. Each layer addresses different aspects of potential vulnerabilities, creating redundancies that strengthen the overall security posture. The philosophy behind Defense in Depth is simple: “No single point of failure”. By combining preventive, detective, and responsive measures, it provides protection against a variety of threats, whether they originate internally or externally. »

Watch the presentation What is the CIA Triad? The CIA Triad is a model in cybersecurity that outlines three core principles—Confidentiality, Integrity, and Availability, that are essential for protecting information. These principles provide a framework for organizations to develop and implement security policies and measures, to safeguarded sensitive data against unauthorized access, tampering, and disruptions. Key Principles of the CIA Triad Confidentiality: Ensuring that information is accessible only to those authorized to access it. »

Watch the presentation What is AAA? AAA stands for Authentication, Authorization, and Accounting, and it is a critical framework in cybersecurity that manages user access and activity within systems and networks. By implementing AAA, organizations can ensure that only authorized individuals gain access to resources, determine what actions they can perform, and keep records of their activities. This structured approach helps maintain security, compliance, and accountability across an organization’s IT infrastructure. »

Watch the presentation What is Security by Design? Security by Design is a proactive approach to cybersecurity that integrates security considerations into every phase of system and software development. Rather than treating security as an afterthought or a separate component, Security by Design ensures that security measures are embedded from the outset. This methodology aims to create systems that are inherently secure, reducing vulnerabilities and minimizing the risk of breaches or attacks. »

Watch the presentation What is Zero Trust Architecture? Zero Trust Architecture (ZTA) is a cybersecurity framework that operates on the principle of “never trust, always verify.” Unlike traditional security models that assume everything inside an organization’s network is trustworthy, Zero Trust Architecture requires strict verification for every user and device attempting to access resources, regardless of their location within or outside the network perimeter. This approach minimizes the risk of unauthorized access, data breaches, and lateral movement by adversaries within the network. »

What is AAA? Authentication, Authorization, Accounting Manages user access and activity Ensures secure and accountable IT environments Key Principles of AAA Authentication Authorization Accounting Authentication Verifies user or device identity Who they are Key Measures for Authentication Passwords: Secret codes for user access Multi-Factor Authentication (MFA): Combines multiple verification methods Biometric Authentication: Uses unique physical traits Authorization Grants or denies permissions What they can do Key Measures for Authorization Role-Based Access Control (RBAC): Permissions based on roles Attribute-Based Access Control (ABAC): Permissions based on user attributes Accounting Tracks and records user activities »

What is the CIA Triad? A cybersecurity model with three core principles. Confidentiality Integrity Availability Confidentiality Protects information from unauthorized access. Key Measures for Confidentiality Encryption: Secure data formats. Access Controls: Restrict data access. Authentication Mechanisms: Verify user identities. Integrity Maintains data accuracy and reliability. Prevents unauthorized modifications. Ensures trustworthy information. Key Measures for Integrity Hashing: Verify data alterations. Version Control: Track data changes. Audit Trails: Log data access and changes. »

What is Defense in Depth? A cybersecurity strategy using multiple security layers. Protects data, systems, and networks. Ensures no single point of failure. Key Principles of Defense in Depth Layered Security Redundancy Diversity of Controls Proactive and Reactive Measures Layered Security Implement multiple, independent security layers. Each layer addresses different threats. Enhances overall protection. Redundancy Failover mechanisms in place. Backup systems to maintain security. Prevents exposure if one layer fails. Diversity of Controls Use various defense types: firewalls, encryption, authentication. »

What is Security by Design? Proactive cybersecurity approach. Integrates security into every development phase. Creates inherently secure systems. Key Principles of Security by Design Foundational Principles Proactive Security Measures Least Privilege Secure Defaults Fail-Safe Defaults Key Principles of Security by Design Proactive Security Measures Integrate security early in development. Identify and mitigate risks initially. Prioritize security from the outset. Key Principles of Security by Design Least Privilege Grant minimal access necessary. »

What is Zero Trust Architecture? Never Trust, Always Verify Strict verification for every access request Foundational Principles Never Trust, Always Verify Least Privilege Access Microsegmentation Never Trust, Always Verify Assume threats inside and outside the network Authenticate, authorize, and encrypt every access Continuous verification for all users and devices Least Privilege Access Grant minimum necessary permissions Reduces impact of compromised accounts Limits access to sensitive data and systems Microsegmentation Divide network into isolated segments Limits lateral movement of attackers Each segment has its own security controls Architectural Strategies Identity and Access Management (IAM) Multi-Factor Authentication (MFA) Continuous Monitoring and Analytics Identity and Access Management (IAM) Manages user identities and access Ensures only authorized users access resources Integrates authentication and authorization Multi-Factor Authentication (MFA) Adds extra verification layers Combines passwords with tokens or biometrics Enhances security against compromised credentials Continuous Monitoring and Analytics Real-time surveillance of activities Detects and responds to anomalies Utilizes advanced analytics and machine learning Operational Tactics Endpoint Security Encryption and Data Protection Endpoint Security Protects all devices accessing the network Uses Antivirus, Anti-Malware Ensures device compliance before access Encryption and Data Protection Encrypt data at rest and in transit Protects sensitive information from interception Ensures data remains unreadable without keys Conclusion Advanced IT: Protects against evolving cyber threats »
