Network Security Controls Administration

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.
