Friday Fun-damental: Creating Effective Information Security Policies

Information security policies provide a framework for protecting critical assets like data, infrastructure, and intellectual property. They specify what needs protection, set standards for security measures, and define individual responsibilities. Most importantly, security policies mitigate risk by reducing vulnerabilities, training employees on best practices, and fostering an organisational culture focused on security. Businesses that implement thoughtful policies position themselves to avoid preventable disasters while complying with expanding regulations.

In this blog, we'll explore best practices for creating effective information security policies tailored to your organisation's specific needs and priorities.?

Why Every Company Needs Strong Information Security Policies

When created thoughtfully, an information security policy provides clarity. It removes inconsistent behaviours at all levels of your business by outlining what the organisation expects, what's prohibited, and who is responsible. This approach is critical given the increasing cost to an organisation, both financially and reputationally, should an information security incident occur.

A robust information security policy will:?

• Ensure data confidentiality, integrity, and availability, as well as data privacy? ?
• Reduce security incident risk and damage
• Create operational information security frameworks within the organisation
• Provide quick responses and clear security statements to third parties, customers, partners, and auditors – customers want confidence in their supply chain
• Fulfil legal and compliance regulatory requirements?

Top Mistakes That Render Information Security Policies Useless

Weak and ineffectual information security policies often consist of technical jargon and legal speak that is unclear or accessible to the end user. This leads to poor or no adoption of the policies within the organisation.?

Complex or unclear policies also tend to create a culture of 'security is too hard to get right.' The policies are seen as a barrier to getting business done, which increases your risk level if staff try to work around policies or systems they deem complex, unclear, or slow. Remember that your information security policy needs to work with the business, not against it, to be effective.?

Another misconception is that security policy exists to protect the organisation from legal action or to mitigate responsibility should a security incident occur. It can, therefore, become a 'box-ticking exercise rather than a valid working document.

All the above issues can be resolved by:

• Creating a clear, concise policy written in non-technical language with the end user audience in mind
• Ensuring any policy is regularly reviewed and updated as regulations, compliance requirements, and threats change?
• Making sure your information security policy is readily available and regularly referred to within the organisation – embedding a culture of good security practices??

Core Considerations When Developing An Information Security Policy For Your Business?

To create an effective information security policy, you must be clear about what you want the policy to achieve. Every part of the policy should be included to address a specific need or requirement within your business; it should be articulated clearly and in simple language, and you must be able to monitor and enforce each part of the policy.

The top five most important considerations for creating a strong infosec policy are:

• Outline: Set a clear objective for what you want the policy to achieve
• Scope: Clearly define who and what you want the policy to apply to
• Purpose: Create the policy based on your organisation's specific risks, regulatory requirements, and desired best practices
• Compliance: Determine how you will enforce the policy
• Management: Actively manage the policy and schedule regular reviews and updates

Key Principles

The policy should incorporate fundamental principles like least privilege, separation of duties, and security by design.

• Least privilege: Give users only the bare minimum access they need to do their jobs. This limits damage from errors or misconduct.
• Separation of duties: Divide roles so no single person has end-to-end control over a process. This provides checks and balances.
• Security by design: Build security into systems from the start rather than bolting it on later. This leads to inherently more secure architectures.

Major Topics

The policy should cover significant topics like:

• Access controls: Set rules for authentication, authorisation, and access management. Enforce need-to-know and least privilege.
• Password policies: Establish strong password requirements and rotation policies.
• Encryption: Mandate encryption for sensitive data in transit and at rest.
• Insider risks: Mitigate risks from insiders through controls like least privilege and separation of duties.

A robust information security management system can be invaluable in this process, enabling you to operate, maintain, and improve your information security policies and data in one place. This ensures you create a solid foundation to build from and ensure ongoing compliance, transparency, and effectiveness.

Best Practices For Developing An Information Security Policy

The most effective information security policies are created collaboratively within an organisation. Engaging every stakeholder, from leadership to IT to legal, fosters a sense of ownership and shared responsibility. Buy-in from all critical business functions is essential to ensure any policy delivers clarity of requirement, consistency of behaviour and meets all regulatory compliance needs.

Assessing your organisation's risk landscape can be one of the best places to start, whether you're looking to create an information security policy from scratch or want to review if an existing policy meets your organisation's needs.

Start by determining:

• Your organisation's internal vulnerabilities, areas of concern, and external supply chain exposure – considering the risks from a data breach through to the chances of a total system outage.
• How any identified risks would impact the confidentiality, integrity, and availability of your data and systems.
• Your organisation's risk appetite, outlining which concerns rank as low, medium, or high risk and how you will address these.
• The regulatory requirements you must meet.

It is also important to consider:

• When classifying your data by sensitivity levels, you can tailor policy controls accordingly, with more sensitive data requiring stricter controls.
• Establishing measured, consistent responses to policy violations, with disciplinary actions that align with offence severity.

Using frameworks, such as the ISO/IEC 27001 standards for information security management systems, to address all relevant elements required for an effective information security policy is also advisable. By taking a comprehensive approach that involves all stakeholders, classifies data appropriately, and responds proportionally to violations, your organisation will be better positioned to protect its most valuable assets and maintain stakeholder trust.

Keeping Your Information Security Policy Current and Effective

An information security policy is only as strong as how well it is maintained. Like any policy framework, set-it-and-forget-it won't cut it in today's rapidly evolving digital landscape. Environments change, new risks emerge, and regulations shift - meaning your policy must adapt in stride to remain relevant.

Follow these best practices to keep your information security policy working for your organisation, not against it.

Conduct Regular Reviews

Schedule reviews of your information security policy at least annually, as well as when significant changes occur to systems, processes, regulations, or risk profiles.

Annual reviews ensure your policy accounts for new technologies, processes, compliance demands, and threat landscapes. Event-triggered reviews help address one-off shifts, like adopting new SaaS platforms, M&A activity, or new regulatory requirements.

Update Intelligently

When reviews determine policies need updating, focus on enhancements that close security gaps and boost clarity. Revisions may include:

• Adding new policy statements to address uncovered risks
• Updating technical controls to automate enforcement better
• Clarifying ambiguous language and requirements
• Tightening access restrictions as needed
• Expanding the scope to cover new systems, processes, assets

Avoid "policy bloat" with excessive new restrictions that offer marginal security value. Lean towards controls with high impact and demonstrable risk reduction.

Communicate Changes Thoughtfully

Once policies are updated, socialise changes across your organisation through:

• Email announcements summarising fundamental changes
• Small group info sessions to brief stakeholders
• Lunch and learns to educate employees
• Classroom/e-learning refreshers on new requirements

Timely, tailored communication reduces confusion and drives the adoption of policy changes.

Enforce Smarter

Automate policy enforcement where possible through technical controls embedded in systems. For example, automatically blocking prohibited device usage or restricting file access by role.

Technical controls eliminate reliance on human judgment and action in policy compliance.

Have clear accountability measures for policy violations, with disciplinary actions proportionate to offence severity. Hold policy refreshers when usage data shows a lack of adherence.

Closing Thoughts on Effective Infosec Policies

A dynamic information security policy is essential for an organisation's commitment to risk reduction. However, static policies quickly lose their edge. Continuous adaptation is vital in today's ever-changing tech and threat landscape. By consistently refining policies and aligning with standards like ISO 27001, organisations not only showcase their dedication to security but also ensure their defences remain robust for the challenges ahead.
