Study Notes
Insider Threats
- Insider threats involve individuals with legitimate access to a network who may misuse their privileges.
- Difficult to detect due to established trust within the organization.
- Have greater knowledge of the network and can bypass external defenses.
Types of Insider Threats
- Pure Insider: Fully embedded employees with potential to cause significant disruption.
- Insider Associate: Contractors or temporary staff with limited access.
- Insider Affiliate: Individuals related to staff members within the system.
- Outside Affiliate: Unaffiliated individuals using deception to access the network.
Key Insider Threat Activities
- Insider IT Sabotage: Misuse of authorized access to disrupt systems.
- Insider Theft: Utilizing IT systems to steal company intellectual property.
- Insider Fraud: Committing identity fraud using company IT resources.
Motivations for Insider Threats
- Personal Factors: Anger, ideology, ego-related issues, personal problems.
- Organizational Factors: Lack of security policies, poor training, and easy access to confidential information.
Behavioral Indicators of Insider Threats
- Evidence of unwanted access and remote connections during odd hours.
- Disregarding company protocols and attempting to access out-of-scope materials.
Malware Overview
- Malware disrupts normal system functions, can steal or delete data, and cause performance issues.
- Delivered through phishing, infected downloads, and compromised software.
Types of Malware
- Trojan: Disguised as legitimate software, requires user action to activate.
- Virus: Attaches to files and activates upon file execution, aiming to disrupt functionality.
- Worm: Self-replicating malware that spreads without user intervention, leading to network issues.
- Ransomware: Encrypts data and demands ransom, often using social engineering tactics.
- Spyware: Collects user data secretly and sends it to threat actors.
- Rootkit: Provides remote access to attackers, designed to remain undetected.
- Adware: Delivers intrusive advertisements; often combined with spyware.
Security Attacks
- Conducted via various threat vectors, targeting individuals or organizations.
- Can be initiated by insiders or outsiders exploiting system vulnerabilities.
Steps in an Attack Process
- Involves reconnaissance, access escalation, data exfiltration, and potential obfuscation.
Digital Signatures
- Provides authentication and non-repudiation, ensuring only the legitimate sender can create a signature.
- Based on a pair of public-private keys, combining identity information and digital signatures for verification.
Application of Cryptography
- Relies on computational resources to maintain security features like encryption and hashing.
- Aims to protect information from unauthorized access.
Network Security
- Essential to safeguarding network availability and protecting data integrity and confidentiality.
- Differentiates between trusted (intranet) and untrusted (internet) zones.
DDoS (Distributed Denial of Service) Attacks
- Utilizes botnets to overwhelm a target with excessive traffic, leading to service unavailability.
Firewall Functionality
- Acts as a barrier between trusted and untrusted networks, controlling data flow.
- Configured with access control lists to regulate permissions based on set rules.
User Identification and Authentication
- Strong mechanisms ensure accountability and traceability of user actions through MFA and biometrics.
Access Control and Permissions
- Role-based (RBAC) and attribute-based (ABAC) controls limit user activities to authorized actions.
Policy Enforcement
- Organizations enforce security policies to ensure compliance, documenting violations for accountability.
Incident Response
- Critical for documenting actions around security incidents to identify responsible parties.
- Relies on robust systems to track incidents effectively.
Compliance and Legal Requirements
- Regulations (e.g. GDPR, HIPAA) mandate tracking and auditing user activities to avoid legal penalties.
- Accountability demonstrates adherence to compliance regulations through detailed activity records.
