Information Security Policy Review

Information security policies are often written once and then left untouched

They may have been created during an ISO 27001 implementation project, copied from a template, inherited from a previous consultant, or written quickly in response to a customer request. At the time, they may have seemed suitable. But as the business changes, policies can quickly become out of date.

New systems are introduced. Suppliers change. Staff roles move. Cloud platforms are adopted. Remote working becomes normal. Customer requirements increase. Risks change. But the policies often stay the same.

ID Risk and Compliance provides information security policy review support to help organisations check whether their policies are current, practical, aligned with business activity and suitable for audit or customer assurance.

Why information security policies matter

Information security policies set expectations for how information should be protected.

They help define responsibilities, control requirements, acceptable behaviour, escalation routes and the way risks should be managed. They also provide important evidence for ISO 27001, customer questionnaires, supplier assurance reviews, tenders and internal governance.

However, a policy is only useful if it reflects what the organisation actually does.

A policy that says access is reviewed monthly, when it is not, creates a compliance gap. A policy that refers to systems no longer used can reduce confidence. A policy that is too generic may not give staff enough practical direction. A policy that is too detailed may become difficult to maintain.

A policy review helps identify these issues before they cause problems during an audit, customer review or internal incident.

Common problems with information security policies

One of the most common issues is that policies do not match reality.

The document may describe a process that no longer exists, name a person who has left, refer to old software, or include controls that have never been fully implemented.

Another common issue is duplication. Businesses may have several policies covering similar areas, such as acceptable use, access control, remote working, mobile devices, cloud services and data protection. If these documents have been written at different times, they may contradict each other.

Some policies are also too vague. They say that information must be protected, but do not explain what this means in practical terms. Others are too complicated and difficult for staff to follow.

There can also be weak links between policies, risk assessments, supplier requirements, training, incident records and actual evidence.

An independent review can help make the policy set clearer, more consistent and easier to maintain.

What an information security policy review includes

An information security policy review can be tailored around your organisation, your existing documentation and your compliance requirements.

The review may include checking whether policies are up to date, whether they reflect current systems and working practices, whether responsibilities are clear, whether requirements are proportionate, and whether the wording is practical enough for staff to understand.

It can also include checking alignment with ISO 27001, the Statement of Applicability, risk assessment, supplier requirements, customer assurance questions and internal evidence.

Policies that may be reviewed include:

Information security policy
Acceptable use policy
Access control policy
Password and authentication policy
Remote working policy
Mobile device policy
Clear desk and clear screen policy
Incident management policy
Supplier security policy
Business continuity policy
Backup policy
Asset management policy
Data classification and handling policy
Document control procedure
Information security roles and responsibilities

The aim is not to create more documents. It is to make sure the policies you have are accurate, useful and capable of being followed.

Aligning policies with ISO 27001

For organisations certified to ISO 27001, or working towards certification, policies need to support the wider information security management system.

They should not sit separately from the risk assessment, Statement of Applicability or Annex A controls.

For example, if access control is identified as an important control, the access control policy should explain how access is requested, approved, reviewed, amended and removed. There should also be evidence that the process is being followed.

If supplier security is included in the Statement of Applicability, the supplier policy should explain how supplier risks are assessed and monitored.

If incident management is required, the policy should be supported by a clear reporting and response process.

ID Risk and Compliance can help check whether your policies properly support your ISO 27001 arrangements and whether they are likely to stand up to audit scrutiny.

Checking whether policies are supported by evidence

A policy on its own is not enough.

Auditors and customers may ask how the policy is implemented. They may want to see records, logs, reviews, approvals, training evidence, incident reports, supplier assessments or screenshots that demonstrate the process is working.

An information security policy review can help identify where evidence exists and where there are gaps.

For example, if the policy says access rights are reviewed, is there a record of those reviews? If staff are required to complete security awareness training, are completion records available? If suppliers are assessed before approval, are supplier review records maintained? If incidents must be logged, is there an incident register?

This helps turn policies from static documents into working controls.

Making policies practical for staff

Information security policies should be written for the people who need to follow them.

If policies are too technical, too long or too generic, staff may not understand what is expected. This can lead to inconsistent working practices and weak evidence.

A review can help identify where wording should be simplified, where responsibilities should be clearer, and where staff guidance may be needed.

This is particularly important for areas such as remote working, use of cloud services, sharing information, handling customer data, reporting incidents, using personal devices, managing passwords and requesting access.

The best policies are not just audit documents. They help staff make better decisions in day-to-day work.

Supporting customer assurance and tender responses

Customers often ask to see information security policies as part of supplier approval, tender submissions or assurance questionnaires.

If policies are outdated, inconsistent or overly generic, this can weaken confidence in the business.

A policy review can help make sure your documents are suitable before they are shared externally. It can also help ensure that questionnaire answers match the policies and evidence held by the business.

This reduces the risk of saying one thing in a customer response while the policy says something different.

For organisations that regularly respond to supplier assurance requests, keeping policies current can save time and improve consistency.

When should policies be reviewed?

Information security policies should be reviewed at planned intervals and when significant changes occur.

Relevant changes may include new systems, new suppliers, changes to cloud services, new customer requirements, changes in working arrangements, security incidents, audit findings, staff changes, new legal requirements or changes to business activities.

Policies should also be reviewed before ISO 27001 certification, surveillance or recertification audits, especially if they have not been updated for some time.

A review is particularly useful where policies were created from templates or inherited from a previous system and have not been properly tailored to the organisation.

Who this service is for

Information security policy review support is suitable for organisations that already have policies in place but are unsure whether they are current, suitable or aligned with their compliance requirements.

It is particularly useful for businesses preparing for ISO 27001 audits, responding to customer assurance requests, reviewing inherited documentation, updating an older ISMS, or trying to make information security arrangements more practical.

It may also be useful where policies have grown over time and now need to be simplified, combined or brought back into line with how the business actually works.
