Data system log review
1. Task description

The organization must be aware of the logs that accrue from the use of different data systems, whether generating the logs is the responsibility of the organization or the system provider. Logs record user actions as well as anomalies, errors, and security incidents.

The adequacy of log should be reviewed regularly. If necessary, log should be usable to determine the root causes for system incidents.

Deployment and regular analysis of security system logs
1. Task description

Security systems (e.g. firewall, malware protection) often have the ability to record a log of events. At regular intervals, make sure that a comprehensive log is accumulated and try to identify suspicious activity. The log is also useful in investigating disturbances or violations.

Logging and review of admin and security logs
1. Task description

The organization must log admin and security logs from used devices and services.

These logs record actions taken by system administrators and privileged users. They help monitor changes to system configurations, user access rights, and other critical settings. By keeping these logs, an organization can audit administrative activities and ensure accountability.

Security logs capture events related to the security of systems and data. This includes login attempts, firewall activities, intrusion detection system alerts, and antivirus actions. Monitoring these logs helps identify suspicious activities that could indicate a security breach or an internal threat.

Monitoring the use of the network and information systems to identify anomalies
1. Task description

Organization's data systems and network must be monitored to detect abnormal use. When anomalities are detected, the organization must take the necessary measures to assess the possibility of security incident.

The monitoring should utilize tools that enable real-time or regular monitoring, taking into account the organization's requirements. Monitoring practices should be able to manage large amounts of data, adapt to changing threat environment, and send alerts immediately when necessary.

Inclusion of the following sources in the monitoring system should be considered:

  • outbound and inbound network and data system traffic

    li>

  • access to critical data systems, servers, network devices and the monitoring system itself
  • critical system and network configuration files
  • logs from security tools (e.g. antivirus, IDS, IPS, network filters, firewalls)

Organization must also establish procedures for identifying and correcting "false positive" results, including tuning monitoring software for more accurate anomaly detection.

Universal cyber compliance language model: Comply with confidence and least effort

In Cyberday, all frameworks’ requirements are mapped into universal tasks, so you achieve multi-framework compliance effortlessly.

Security frameworks tend to share the common core. All frameworks cover basic topics like risk management, backup, malware, personnel awareness or access management in their respective sections.
Cyberday’s universal cyber security language technology creates you a single security plan and ensures you implement the common parts of frameworks just once. You focus on implementing your plan, we automate the compliance part - for current and upcoming frameworks.
