In the current digital age, the astounding volumes of data that is created and transferred, need information security policies to prevent its unethical breach. These policies serve as a crucial foundation for organisations to safeguard their valuable assets, like confidential customer information, intellectual property, and proprietary business data.
Information security policies create a road map for enhancing data confidentiality, integrity, and availability by developing a complete set of rules and principles.
Information security regulations cover more than simply computers and networks. It covers all facets of how an organisation does business, such as physical security, human resource management techniques, and data handling protocols.
Specific goals are outlined in these rules, including avoiding unauthorised access, identifying and reducing cyber threats, guaranteeing compliance with legal and regulatory obligations, and fostering an information security awareness culture.
In this blog, we discuss the information security policies each Australian and global organisation should include to prevent data and information breaches.
Understanding Cybersecurity in Information Security Policies
Cybersecurity and its Fundamental Elements
Cybersecurity is the process of guarding against unauthorised access, use, disclosure, interruption, alteration, and destruction of information systems and networks. It entails putting in place a variety of safeguards, including network monitoring, firewalls, antivirus software, encryption, and sensitive data protection, to secure against cyber-attacks.
Role of Cybersecurity in Protecting Information Assets
The confidentiality, integrity, and availability of information assets are crucially dependent on cybersecurity. Organisations may protect their data against cyberattacks, unauthorised access, and data breaches by putting strong security measures in place. To reduce possible harm, cybersecurity aids in spotting vulnerabilities, controlling risks, and successfully handling security crises.
Linking information security policies to cybersecurity measures
Effective cybersecurity measures might be implemented inside an organisation using information security policies, which include instructions and processes. These policies cover incident response processes, security measures, and staff roles and responsibilities. Organisations may create a strong security posture and safeguard their priceless information assets by coordinating information security policies with cybersecurity best practices.
Four Key Information Security Policies
To prevent information compromise, the policies under this outcome specify how entities should manage and categorise official information. Additionally, they outline how to protect government information and communication technology systems, minimise common and new cyber risks, and give appropriate and secure access to official information.
The following supporting requirements and the four core requirements in these policies outline what entities must do to attain the information security outcome.
1) Sensitive and Classified Information
Purpose
This guideline explains how to classify information appropriately based on its sensitivity or security. To prevent information breaches, it also outlines marking, handling, storage, and disposal protocols.
Overview
To appropriately guard against information compromise, entities must consider:
- Confidentiality – Who should be able to see the information and why?
- Integrity – Assurance that information is only being created, amended, or deleted by the intended authorised means and is correct and valid.
- Availability – Ensuring authorised persons have access to information when and as needed.
The Australian Government utilises the following three security classifications:
- PROTECTED
- SECRET
- TOP SECRET
Other information obtained from business services and operations is considered ‘OFFICIAL’ or, in case it is sensitive, it is called ‘OFFICIAL: Sensitive’.
The person who created the document oversees assigning it the appropriate sensitive or security classification. To achieve this, they must evaluate the Business Impact Level (BIL) considering the potential harm that might result from compromising the information’s confidentiality. The power over the sanitisation, reclassification, or declassification of such material stays with the original creator.
In addition to the security classification or sensitive labelling, some information may require additional safeguards. To signify these additional precautions, caveats are utilised.
The toughest access and mobility restrictions are necessary for some types of information. This is designated as responsible material by the author.
Information management markers are an optional way for entities to identify information that is subject to non-security-related restrictions on access and use.
Information on systems that store, process, or communicate confidential or security-sensitive information must be marked with the Australian Government Recordkeeping Metadata Standard. Security-sensitive information must be properly maintained, transmitted, and disposed of by entities.
2) Access to Information
Purpose
This policy lays forth the security safeguards that enable an institution to grant timely, appropriate, and reliable access to official information.
Overview
When discussing sensitive or classified information with others or revealing material to the public, access to OFFICIAL government information must be carefully regulated.
Entities should consider the data they share and reveal. When exchanging information with those outside of the government, they must have plans in place.
Entities are required to verify that individuals working with the government have the necessary security clearance and a need to know. For a select group of Australian office holders, access exceptions apply.
Information that is caveated is subject to strict safeguards.
The following releasability caveats are noteworthy:
- Australian Eyes Only (AUSTEO)
- Australian Government Access Only (AGAO)
- Releasable to (REL) restricts access to resources according to citizenship.
Temporary access to restricted resources may be needed in some special cases. After weighing the security concerns, access may be provided temporarily or for a limited time.
Entities must implement procedures to regulate access to information systems that include sensitive and restricted data.
3) Safeguarding Data from Cyber Threats
Purpose
The Australian Government is subject to common and new cyber dangers, which are addressed in this policy.
Overview
Entities have to minimise the risks associated with cyber security. The Australian government should fight off both domestic and international adversaries who want to steal data, destroy data, or prevent systems from functioning.
Entities are frequently threatened by external opponents who want to steal their data. These enemies frequently try to access systems and data through phishing emails and websites. It is imperative that organisations protect the information stored on devices capable of receiving emails or browsing the internet.
The Australian Cyber Security Centre (ACSC) estimates that many cyber security incidents could be mitigated by implementing eight essential mitigation strategies known as the ‘Essential Eight- external site’. These mitigating techniques form the core of cyber security.
Furthermore, conducting an information security risk assessment is a crucial step in identifying vulnerabilities and aligning with robust information security policies.
However, no single mitigation strategy, or set of mitigation strategies, is guaranteed to prevent a cyber security incident.
Each entity should decide which of the other mitigation measures from the fact sheet Strategies to Mitigate Cyber Security Incidents-external site of the ACSC they should put into place to safeguard their entity.
Entities should comply with the maturity level 2 criteria in the Essential Eight- external site Maturity Model to reach a ‘Managing’ maturity level for each of the eight necessary mitigation measures from the measures to Mitigate Cyber Security Incidents- external site.
Governmental organisations are required to take precautions to avoid putting the general public at unwarranted risk for cyber security while conducting business with them online.
4) Robust ICT Systems
Purpose
To enable the ongoing and secure operation of government business, this policy outlines how to protect information and communication technology (ICT) systems.
Overview
A linked group of hardware and software components that process, store, or transmit information, along with the regulatory environment in which they function, make up an ICT system.
Entities must successfully follow the ISM’s (Australian Government Information Security Manual) cyber security principles in order to protect ICT systems from cyber attacks.
- Govern: Identifying and addressing security issues.
- Protect: Putting security mechanisms in place to lower security threats.
- Detect: Recognising and interpreting cyber security incidents.
- Respond: Addressing cyber security problems and recovery.
Only ICT systems that the deciding authority has approved may be used by entities.
A 6-step, risk-based strategy for cyber security is provided by the ISM. Before they allow or reauthorise the usage of systems, entities must take this into account.
Information about the Australian Government that is processed, saved, or shared through a third-party cloud service provider is safeguarded in the same way as internal entity services. The same permission remains in effect for the duration of the ICT system/service to run a framework to control security threats.
Internet Gateways
An information flow management tool that controls information flows between linked networks from various security domains is known as a gateway. The Australian Signals Directorate criteria for secure internet gateways must be implemented by entities.
Thus, organisations may strengthen their security posture, safeguard their important data, and inspire trust in their stakeholders by creating strong information security policies and routinely assessing and upgrading them.
