Regulation and Compliance

In response to increasing cyber threats, federal governments have implemented various regulations and compliance standards to safeguard public sector information systems and data.

These regulatory frameworks aim to establish a baseline for cybersecurity practices, enforce data protection, and ensure a uniform response to cyber incidents. Below are four examples of cybersecurity regulations in the public sector.

United States: Federal Information Security Management Act (FISMA)

The Federal Information Security Management Act (FISMA) is a federal law enacted in 2002 in the United States. This law requires all federal agencies to establish a comprehensive framework to protect government information, operations, and assets from natural and artificial threats.FISMA mandates that each agency must develop, document, and implement a program that provides information security for all the information and information systems that support the operations and assets of the agency, including those handled by third parties.

Key aspects of FISMA include:

European Union: General Data Protection Regulation

GDPR is a set of regulations that came into effect in May 2018, aimed at harmonizing data privacy laws across Europe, protecting and empowering EU citizens' data privacy, and changing how organizations approach data privacy. GDPR's broad scope and stringent requirements have significantly impacted how public sector agencies in the EU handle and secure personal data.

Under GDPR, public sector entities are required to:

  • Ensure the protection of personal data
  • Provide transparency about data processing activities
  • Enable individuals to exercise their privacy rights (right to access, rectify, and erase personal data)
  • Report certain types of data breaches

Australia: The Australian Government Information Security Manual

The Australian Government Information Security Manual (ISM) is a set of guidelines developed by the ACSC for government ICT systems. It provides mandatory and advisory security controls to protect information and systems from unauthorized access, modification, or loss. The ISM is regularly updated to address new and evolving cyber threats, ensuring best practices in information security. It includes areas such as:

Cybersecurity Act of 2018 (Singapore)

Singapore's Cybersecurity Act of 2018 aims to protect Critical Information Infrastructure (CII) in essential sectors and enhance national cybersecurity defenses.
