Personnel activity is monitored to detect potential cybersecurity events.

A process for reporting incidents is maintained to help staff report incidents efficiently and consistently.

Things to report as an incident include e.g.:

• unauthorized access to data / premises
• action against security guidelines
• suspected security issue (e.g. phishing, malware infection)
• data system outage
• accidental or intentional destruction / alteration of data
• lost or stolen device
• compromised password
• lost physical identifier (e.g. keychain, smart card, smart sticker)
• suspected security weakness (e.g. on utilized data system or other procedures)

The personnel guidelines emphasize the obligation to report security incidents as soon as possible in accordance with the agreed process. The instructions also describe other operations in the event of an incident (e.g. recording seen error messages and other details).

The organization must have list of approved applications, and application sources, that are allowed to be used on the organization's endpoint devices.

The organization should, if possible, execute management of approved software using automation for example with policies from mobile device management system.

Examples of traffic filtering and monitoring systems are firewalls, routers, intrusion detection or prevention systems (IDS / IPS) and network devices / servers / applications with similar functionalities.

To ensure the functionality of filtering and monitoring:

• An owner has been appointed for the systems, who takes care of the proper operation of the system throughout the life cycle of the data processing environment
• It is the responsibility of the system owner to add, change, and delete settings for systems that filter or control traffic
• Documentation of the network and associated filtering and control systems is maintained throughout its lifecycle as an integral part of the change and settings management process
• The settings and desired operation of the systems are checked periodically during the operation and maintenance of the data processing environment and in the event of exceptional situations

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.
