A cybersecurity risk management policy outlines a systematic process of cyber risk identification, assessment, and management in an enterprise. It describes how the organization protects its infrastructure, systems, networks, applications, data, and end-users from cyber attacks. The policy also assigns specific roles and responsibilities to different stakeholders in the company. A properly developed policy allows businesses to focus on prevention rather than reaction.
Importance of Cybersecurity Risk Management Policy
Today, almost every organization relies on various types of technology, cloud-based solutions, interconnected devices, and online services. This reliance poses certain risks that can be exploited by cybercriminals. A cybersecurity risk management policy allows businesses to identify their critical assets and the potential impact of their exploitation. It enables businesses to make uniform security decisions, increase their compliance with regulations, and helps management in allocating investments in cybersecurity. Such a policy also needs to be updated periodically since cyber risks, technologies, business processes, and regulations are constantly evolving.
Risk Identification and Risk Assessment in Cyber Security
Risk identification is an essential element of risk management in cyber security. First of all, organizations need to define valuable assets, such as information about customers, financial information, intellectual property, personal data of employees, databases, applications, and infrastructure of the organization. Then they need to think of threats, which include phishing, ransomware, malware, insider threat, unauthorized access, data breach, etc. It will help to understand the probability of the threats and their possible impact. In turn, risks can be prioritized in terms of their level of importance.
Steps Towards An Effective Risk Management Process
The most effective cybersecurity risk management process will be one which spells out the steps to manage any risks that have been identified. It is possible for organizations to mitigate risks by securing their systems, transferring some risks through insurance, avoiding activities that lead to unacceptable risks, or accepting acceptable levels of risks. The process needs to define roles regarding security and reporting of incidents, along with how the incidents escalate.
Security Controls Definition
Security controls are security mechanisms put in place to prevent, detect, and counter cyberattacks. They could take the form of technology, process, policies, or administrative actions. Security controls go hand in hand with the risk management strategy by translating security needs into concrete protective actions. For instance, an organisation could recognise unauthorised access as one of its key risks and implement multi-factor authentication, restrictions, and surveillance as controls.
Types of Security Controls
Security controls can be broadly classified into preventive, detective, and corrective security controls.
- Preventive security controls aim to prevent security incidents. Some examples of preventive security controls include firewalls, strong passwords, multi-factor authentication, access controls, and security awareness training.
- Detective security controls work by identifying suspicious behaviour or security incursions through tools such as intrusion detection systems, security monitoring, auditing, and alerting.
- Corrective security controls restore order after a security incident and involve backup and restoration of systems.
Access Control and Data Protection
Access control is a very important security control, as employees need only access to the information and systems required for their work. Role-based access, authentication, privileged access management, and regular access reviews are some ways to minimise unauthorised activities. There are also data protection controls that will help keep information safe through encryption, proper storage, backup, and controlled data exchange.
