Cybersecurity risks are constantly changing, and the information security documentation that supports your organization must change with them. An information security risk register assists the business to identify, evaluate and rank and control risks that may impact on sensitive information, systems, employees, customers and daily operations. But, unless this register is frequently examined, it is soon likely to be obsolete. Risks that may be not reflected in an older register can be caused by new technologies, new cyber threats, changes in an organization, security incidents, and regulatory requirements.
In Saudi Arabia, organizations, in particular, should have the risk information updated, particularly when it comes to developing an Information Security Management System Saudi Arabia or maintaining it. With a correct risk assessment, security teams and management get a better understanding of the existing vulnerabilities as well as make informed decisions regarding the security measures and risk treatment. You need not start afresh in case your risk register is not reviewed recently. A systematic review may assist in determining what is different, what must be eliminated and what risks are new and need to be addressed.
Why Does a Risk Register Become Outdated?
A risk register can become outdated simply because the organization has changed. New software, cloud services, new employees, new suppliers, new applications and new business processes are introduced regularly to businesses. Such changes may result in new security risks or altering the existing ones.
The threat arena is also evolving at a high rate. Phishing, ransomware, credential theft, data breach, and unauthorized access are some of the ways cybercriminals are continually developing. A risk that was deemed as low a few months ago, might need a new evaluation today.
Other reasons are:
New regulatory or contractual requirements.
Changes in business operations.
Cloud migration
New suppliers or third parties
Technology upgrades
Security incidents
Alterations to important information resources.
New vulnerabilities
Organizational restructuring
1. Review Every Existing Risk
Begin by going through each item in the information security risk register. Decide on whether the risk is still topical and whether its probability, effect, measures and ownership still stand.
Ask important questions such as:
Does this risk still exist?
Is there a change in the affected asset?
Has the risk been decreased or increased?
Is there a change in the potential impact?
Are the existing controls effective?
Is the risk owner assigned still responsible?
Is the treatment plan suitable?
This review can be used to differentiate between active risks and outdated/irrelevant entries.
2. Update Your Asset and Process Inventory
Security risk can only be properly evaluated when you are aware of what is to be secured. Audit your information assets, applications, databases, networks, cloud environments, endpoints, as well as critical business processes of your organization.
As an example, instances of a cloud migration can involve alternative considerations of access, configuration, supplier, and data protection. Likewise, the more information is gathered about the customers, the more significant a data breach may be.
Ensure the risk assessment is done with new assets and processes and that they are linked to the relevant risks.
3. Identify Emerging Cybersecurity Threats
A register that has become outdated can be concerned with those threats that were significant at the time of its creation. Review your new threat assessment on your new technology and business environment.
The threats that can be relevant are:
Phishing and social engineering.
Ransomware
Business email compromise
Credential theft
Insider threats
Cloud misconfiguration
Software vulnerabilities
Third-party security incidents
Data leakage
Unauthorized access
Remote-work security risks
The aim is not to enumerate all the potential cyber threats. Look at threats that are likely to have an impact on your organizations assets and operations.
4. Reassess Risk Likelihood and Impact
Whenever there is a change in circumstances, risk ratings ought to be reviewed. Once an issue that was previously low risk is made business critical or when it starts handling sensitive information, it can develop into a more serious problem.
Consider the probability and consequences based on standards in place in your organization. Think about the potential impact on confidentiality, integrity, availability, finances, operations, customers, reputation and compliance.
Also check on the effectiveness of the current controls prior to assessing the remaining or residual risk.
5. Check Security Controls
Modifying risks without evaluating controls may provide holes in your evaluation. Test to confirm the effectiveness of security controls like access controls, encryption, backups, monitoring, employee awareness training, vulnerability management and incident response procedures.
A difference exists between a documented control, and one that works in practice, too. Reviewing and testing controls may expose previously undetected weaknesses in controls.
6. Learn From Security Incidents
Security incidents can be used to get valuable information on how to manage risks. In case your organization has undergone phishing, malware, unauthorized access, exposure of data, or any other security incident, find out whether the incident has already been captured in the information security risk register.
Consider whether:
The risk was underestimated
Existing controls were insufficient
There must be a new risk added.
The risk rating should change
Additional controls are necessary
Based on the lessons learned during incidents, the similar issues may be avoided in the future evaluation.
7. Review Third-Party Risks
These third parties can be suppliers, cloud providers, contractors, and other third parties, who can pose a lot of information security risks. Examine if sensitive information, systems or business processes are accessible to vendors.
In case of the introduction of a new supplier or a change in the relationship with an existing supplier, it is possible to question whether the risks and security requirements also require revision.
Contractual requirements, security responsibility, data handling, access privileges should be also taken into account in the context of third-party risk management, as well as monitoring the suppliers.
8. Align Risk Management With Your ISMS
The wider information security program of the organization should be linked to risk management. A successful Information Security Management System Saudi Arabia strategy must also be connected to the risk identification and security controls, treatment plans, policies, monitoring and continuous improvement.
The aim of having a risk register cannot merely be to meet an audit requirement. It must assist the management in knowing the exposure to security and make decisions on where to put resources and security enhancements.
9. Create a Regular Review Process
Waiting until an audit or security incident has occurred to update your register is a bad idea. Implement a routine review procedure and carry out other evaluations at a time that there are drastic changes.
The review can be brought about by:
Major technology changes
New business activities
Organizational restructuring
Significant security incidents
New regulatory requirements
New suppliers
Changes to sensitive data processing.
Periodic reviews are useful in ensuring the information security risk register is not obsolete with the changes in the organization.
10. Keep Clear Evidence of Updates
Record the time and date of the review, the participants, risks that were altered and the reasoning. Keep records of evidence like risk assessment, control reviews, treatment plans, meeting records and management approvals.
This documentation can enhance governance, accountability, constant improvement, and security evaluation to organizations, which are seeking to be stronger in Information Security Management System Saudi Arabia.
Conclusion
An outdated risk register can create gaps between an organization's actual security environment and what its documentation says. Conducting an asset review, highlighting the threats that are emerging, re-evaluating the probability and impact, verifying controls, and integrating incident-lessons can allow organizations to keep a more realistic view of their cybersecurity risks.
Risk information should be kept up-to-date and not a one-time task. By using a structured method and having the assistance of well-trained security experts like SecureLink, organizations can enhance their risk management procedures and develop a more efficient information security risk register that facilitates the organization of security planning, governance and relentless enhancement.
