Study Notes
Network Security Controls Administration
Types of Security Controls
- Physical Controls: Access control, surveillance, and environmental controls to prevent unauthorized physical access to network devices and data.
- Technical Controls: Firewalls, intrusion detection/prevention systems, encryption, and access controls to protect against unauthorized access and malicious activities.
- Administrative Controls: Policies, procedures, and training to ensure personnel understand security policies and procedures.
Security Controls Administration Tasks
- User Account Management: Create, modify, and delete user accounts, assign access levels, and manage passwords.
- Firewall Configuration: Configure firewall rules, monitor logs, and update firmware/software.
- Intrusion Detection/Prevention System (IDPS) Management: Configure IDPS, monitor alerts, and update signatures.
- Encryption Key Management: Generate, distribute, and manage encryption keys.
- Vulnerability Management: Identify, classify, and remediate vulnerabilities in network devices and systems.
- Incident Response: Respond to security incidents, contain and eradicate threats, and conduct post-incident activities.
Security Controls Administration Best Practices
- Least Privilege: Grant users and systems only the necessary access and privileges.
- Separation of Duties: Divide responsibilities to prevent a single individual from having too much control.
- Job Rotation: Rotate personnel through different roles to reduce the risk of collusion and fraud.
- Dual Control: Require two or more individuals to authorize and perform sensitive tasks.
- Regular Audits and Reviews: Regularly review and audit security controls to ensure compliance and effectiveness.
Security Controls Administration Tools
- Security Information and Event Management (SIEM) Systems: Monitor and analyze security-related data from various sources.
- Network Configuration Management Tools: Manage and track network device configurations, firmware, and software updates.
- Vulnerability scanners: Identify vulnerabilities in network devices and systems.
- Encryption Management Tools: Manage encryption keys, certificates, and encrypted data.
