Study Notes
Access Control
- Definition: Restricting access to computer resources to authorized users, limiting the potential damage from unauthorized access or malicious behavior.
-
Types of Access Control:
- Discretionary Access Control (DAC): Access is granted based on user identity and permissions.
- Mandatory Access Control (MAC): Access is granted based on a set of rules that are applied to all users.
- Role-Based Access Control (RBAC): Access is granted based on a user's role within an organization.
-
Access Control Models:
- Bell-LaPadula Model: Focuses on confidentiality and ensures that sensitive information is not accessed by unauthorized users.
- Biba Model: Focuses on integrity and ensures that data is not modified without authorization.
Vulnerability Management
- Definition: The process of identifying, classifying, prioritizing, and remediating vulnerabilities in an organization's systems and applications.
-
Vulnerability Management Process:
- Vulnerability Identification: Identifying potential vulnerabilities through scanning, penetration testing, and code reviews.
- Vulnerability Classification: Classifying vulnerabilities based on their severity and potential impact.
- Vulnerability Prioritization: Prioritizing vulnerabilities based on their severity and potential impact.
- Vulnerability Remediation: Implementing patches, updates, or other fixes to remediate vulnerabilities.
-
Vulnerability Scanning Tools:
- Network Vulnerability Scanners: Scan networks for open ports, services, and potential vulnerabilities.
- Web Application Scanners: Scan web applications for vulnerabilities such as SQL injection and cross-site scripting.
Intrusion Detection
- Definition: The process of monitoring network traffic and system logs to identify potential security threats.
-
Intrusion Detection Systems (IDS):
- Network-Based IDS (NIDS): Monitors network traffic for signs of unauthorized access or malicious activity.
- Host-Based IDS (HIDS): Monitors system logs and files for signs of unauthorized access or malicious activity.
-
Intrusion Detection Techniques:
- Signature-Based Detection: Identifies known attack patterns using signatures.
- Anomaly-Based Detection: Identifies unusual behavior that may indicate a security threat.
Firewall Configuration
- Definition: A network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules.
-
Firewall Types:
- Network-Based Firewalls: Filter traffic based on source and destination IP addresses, ports, and protocols.
- Host-Based Firewalls: Filter traffic based on application and system-level rules.
-
Firewall Configuration:
- Default Deny Policy: Blocks all incoming traffic by default, only allowing traffic that is explicitly permitted.
- Rule-Based Configuration: Configures firewall rules based on specific ports, protocols, and IP addresses.
Encryption
- Definition: The process of converting plaintext data into unreadable ciphertext to protect it from unauthorized access.
-
Encryption Types:
- Symmetric Encryption: Uses the same key for encryption and decryption.
- Asymmetric Encryption: Uses a pair of keys, one for encryption and another for decryption.
-
Encryption Algorithms:
- AES (Advanced Encryption Standard): A widely used symmetric encryption algorithm.
- RSA (Rivest-Shamir-Adleman): A widely used asymmetric encryption algorithm.
