This task requires a documented procedure for backup and restore testing.

Open, unused, or unnecessary ports can serve as potential entry points for attackers. This task involves checking all devices and systems for any open, unused, or unnecessary ports and closing them if not required. It includes verifying that only necessary ports are open and following the principle of least privilege. Do you have access to the device configurations? Are you familiar with the network's port requirements? This task requires reviewing and updating the network's port configurations.

Rogue devices connected to the network can pose a significant security risk. This task involves regularly scanning the network for any unauthorized or unidentified devices and taking necessary actions to isolate them. It includes implementing network access control measures to prevent rogue devices from connecting. Do you have a process in place to detect and isolate rogue devices? Are you familiar with the network's authorized device list? This task requires a documented process for identifying and isolating rogue devices.

Monitoring the network for suspicious activity can help in identifying potential security incidents and taking timely actions to mitigate them. This task involves implementing a network monitoring solution and establishing alert mechanisms for detecting suspicious activities. Do you have a network monitoring tool in place? Are you aware of the common signs of suspicious network activity? This task requires configuring the network monitoring solution and setting up alerts.

Unused or unnecessary services and protocols can increase the attack surface and expose the network to potential vulnerabilities. This task involves identifying and removing any services and protocols that are not required for the network's operation. It includes reviewing device configurations and disabling or uninstalling unnecessary services and protocols. Are you familiar with the services and protocols used in the network? Do you have access to the device configurations? This task requires reviewing and updating the network's device configurations.

Intrusion detection and prevention systems help in identifying and blocking unauthorized access attempts and suspicious activities in real-time. This task involves implementing intrusion detection and prevention systems for the network. It includes deploying the necessary hardware or software solutions and configuring them to detect and prevent intrusions. Are you familiar with intrusion detection and prevention systems? Do you have access to the necessary resources for implementation? This task requires configuring the intrusion detection and prevention systems.

System logs provide valuable information for detecting and investigating security events. This task involves configuring the system logs of all devices and applications to capture relevant security events. It includes defining log retention policies and ensuring that logs are stored securely. Do you have access to the device and application configurations? Are you familiar with the log management tools and practices? This task requires configuring the system logs to capture security events.

Network security requires regular maintenance to stay effective. This task involves creating a plan that outlines the necessary activities and schedule for ongoing network security maintenance. It includes tasks such as regular vulnerability scanning, software updates, password changes, and policy reviews. Are you familiar with the network security maintenance requirements? Do you have access to the necessary resources for maintenance? This task requires creating a documented plan for ongoing network security maintenance.

Employees play a critical role in network security. This task involves conducting cyber security training sessions for all employees to educate them about the best practices, potential threats, and their responsibilities in maintaining network security. It includes providing training materials, conducting interactive sessions, and assessing employee understanding. Are you responsible for employee training? Do you have access to cyber security training resources? This task requires scheduling and conducting cyber security training sessions.
