Network segmentation and filtering practices within the classification level
1. Task description

Tietoliikenneverkon vyöhykkeistäminen ja suodatussäännöstöt on toteutettava monitasoisen suojaamisen periaatteen mukaisesti.

Tietoliikenneverkon jakaminen ko. turvallisuusluokan sisällä erillisille verkkoalueille (vyöhykkeet ja segmentit) voi tarkoittaa esimerkiksi tietojen suojaamisen näkökulmasta tarkoituksenmukaista työasema- ja palvelinerottelua, kattaen myös mahdolliset hankekohtaiset erottelutarpeet.

Vaatimus voidaan täyttää alla mainituilla toimenpiteillä:

  • Tietoliikenneverkko on jaettu ko. turvallisuusluokan sisällä erillisiin verkko-alueisiin (vyöhykkeet, segmentit).
  • Verkkoalueiden välistä liikennettä rajoitetaan ja ympäristöön sisäänpäin tulevaan liikenteeseen noudatetaan default-deny sääntöä.
  • Tietojenkäsittely-ympäristössä on varauduttu yleisiin verkkohyökkäyksiin.

Monitoring configurations
1. Task description

Configurations should be monitored with comprehensive system management tools (e.g. maintenance utilities, remote support, enterprise management tools, backup and recovery software) and reviewed regularly to assess settings, password strengths, and operations performed. Actual configurations can be compared to defined target models. Any discrepancies must be dealt with either automatically or by manual processing.

Any unauthorized changes must be corrected and cause investigated and reported.

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.
