Question 1) Is this vision of a "second" residual risk correct?
Answer: I think there is a misunderstanding here. When you apply a policy over an "inherent risk" you are already treating a risk (first you would have to evaluate the inherent risk against the acceptance criteria - the risk appetite). If this first residual risk after applying this control is still over risk appetite you have two options: accept the residual risk as it is (because applying more controls will not be worthy), or apply additional controls to further decrease the risk (then you would have the "second", "third" residual risk, and so on).
Considering this, before applying any control you have to evaluate the inherent risk first.
Question 2: Can I use the same controls assessment policy for estimating "second" residual risk?
Answer: The methodology you use to assess the inherent risk can also be used to assess the risk after the control application.
Internal auditors and competence
We've received additional questions:
> Are the surveillance audits a new requirement of the ISO 9001:2015 standard?
> What happens if we don’t do the surveillance audits and just do the renewal on year 3?
Answer
Surveillance audits are not a requirement of ISO 9001:2015. Surveillance audits are a requirement from your contract with the certification body. Certification is not an ISO 9001:2015 requirement. Certification is a management decision. Many organizations use ISO 9001 as help to implement a management system without performing the extra step of certification.
ISO 9001 only mentions internal audits.
Certification bodies cannot propose a contract that does not include surveillance audits because that would go against their accreditation procedures.
Continual improvement
Answer:
There are not mandatory documents required by clause 10.3- Continual Improvement. However, your organization needs to demonstate continual improvement by reviewing the documentation and processes as the quality management system matures or when there is a new process implemented. The organization can use the data output from its processes, for example results from internal audits, management reviews, etc. to support that continual improvement is happening.
Answer: If you do not have evidences to show compliance with all requirements from sections 4 to 10, and that controls from Annex A stated as applicable in the Statement of Applicability (SoA) are implemented and working it makes no sense to go for a certification audit, since the certification auditor will not have enough evidences to verify if the ISMS is implemented and operational.
2. How long should I be operational prior conducting the audit? 6 mos minimum.
Answer: A good reference you can use to define the time you need a process or control to be operating to have enough data to be audited is to ensure it has already completed at least three cycles of operation. For example, if a full backup process is performed once a week, then you should wait at least three weeks to audit this process.
But it is important to note that certification bodies have their own criteria about the duration of the ISMS operation before the certification, so you must contact then previously to align this situation.
Paper-based or electronic records?
Answer:
The best practice is the one that is best for you. The purpose of the records is that they confirm that some work has been done. How these records will be organized depends solely on your business and core process:
a) what kind of jobs do you have (whether it's manual work in a workshop where there is no computer or tablet, or it's all automated and directly involving a computer/server);
b) are electronic forms always available to all employees;
c) whether the records are easily retrieved in case they need to prove compliance;
d) whether the records are protected from manipulation (subsequent data modification) or loss (whether there is a corresponding back-up).
In any case, it is recommended not to duplicate records where it is not needed (eg legal obligation).
According to ISO 9001:2015 the organization needs to conduct reviews, verification and validation to ensure that the results of design and development meet the necessary requirements. If the approver performs one of these activities then you require this role. If your company already conduct these three processes you don´t need the approver to release the drawings and comply with the standard requirements.
A la hora de planificar tanto las etapas como los controles del diseño y desarrollo de sus productos y servicios la organización necesita tener en cuenta qué tipo de actividades van a ser necesarias así como la duración de las mismas y su grado de complejidad.
Con respecto a este punto 8.3.2 (planificación del diseño y desarrollo) debe de conservar los registros relativos para demostrar que se han cumplido con los requisitos de diseño y desarrollo. Es decir que la organización necesita proporcionar algún tipo de evidencia objetiva de qué es lo que incluyen las actividades de planificación. Esto se puede conseguir con el uso de cronogramas diagramas de Gantt o cualquier otro método de planificación como algún tipo de administrador de proyectos.
Implementing ISO 27001 information security risk management
Step 1: Identify the internal and external issues in our company
Step 2: Identify the risks and opportunities that would arise from each internal and external issue
Step 3: Bring the risk items identified during "step 2" to risk assessment
Step 4: Devise a separate plan to utilize the opportunities.
Step 5: Develop the risk treatment plan.
Answer:
To be compliant with ISO 27001 the risk management must follow these steps:
- Definition of a risk assessment and treatment methodology
- Performing of risk assessment (risk identification and risk analysis)
- Performing of risk treatment (risk evaluation and controls selection)
- Elaboration of a risk treatment report
- Elaboration of Statement of Applicability (SoA)
- Elaboration of Risk Treatment Plan and acceptance of residual risks
1. Shouldn't I review all the companies ISMS documents prior to creating the audit plan or is this not necessary for a Full System ISMS Internal Audit? The company advises me that there will be approximately 160 documents which they're expecting me to review during the scheduled audit where they've estimate d to take 5 days based on other audits they've had in the past. My understanding from the training is that I should review all their documents 1st, then develop the audit plan although it's not an ISMS mandatory document by the standard.
Answer: First it is important to note that ISO 27001 does not prescribe the steps for performing internal audit, only that it must be performed periodically, expected inputs and outputs. Considering that, the review of ISMS documents is not mandatory.
The review of ISMS documents prior to developing the internal audit plan is useful for you to identify situations specific to your organization that you should look for (e.g., the name of a record, the periodicity of a task, etc.), but not being able to review all documents should not be an impediment for you to plan your internal audit. In this case you should focus on documented information required by the main clauses from the standard (from sections 4 to 10), and on documents and methods of implementation defined for controls from Annex A stated as applicable in your Statement of Applicability (SoA), and make an observation that some specifics of your organization may not be properly audited, and that there is a risk that nonconformities related to them may be found during the certification audit (this is a risk that your management has to accept if you do not have time to review all documents).
Examples of minimal documents you must include in your review are the ISMS scope, ISMS policy, risk assessment and treatment report.
One additional thing we should mention is that 160 documents for an ISMS is a very uncommon quantity for a set of documents (for small and medium sized companies the set of documents would be no more than 40 to 50), then maybe you have space for an improvement related to decrease the quantity of documents.
