Cyber security controls can be defined as the set of tools that help in prevention, detection, and mitigation of cyber crimes or threats. Cyber security controls can be broadly classified as administrative, physical, technical, and operational. Every set of controls deals with a specific threat vertical.
Different types of cyber security controls are:
- Preventive controls
- Detective controls
- Corrective controls
- Recovery controls
- Compensating controls
In order to ensure effectiveness, every set of security controls needs to be employed efficiently. Once you have established a cyber security control strategy, it is advised to regularly test the efficiency of cyber security controls to find any misconfiguration. This helps refine the cyber security control implementation to improve the detection and prevention of cyber threats and recovery from cyber-attacks if any.
But, how can you measure the efficiency of cyber security controls?
There are numerous methods to assess security control efficiency. These methods can be classified based on their approach.
- Indirect Assessment
- Direct Assessment
Indirect assessment involves collecting data from sources such as perimeter servers, DNS configurations, etc., to analyze security risks likely to be faced by the organization.
Direct assessment involves testing and measuring the operations and configuration of security controls.
Let us delve deeper into methods to measure security control effectiveness:
- Analyze Attack Surface: To understand the effectiveness of security controls, organizations first need to understand their attack surface. Attack surface refers to network backdoors that can act as entry path for cyber-attacks. The attack surface comprises exposed credentials, misconfigurations, vulnerabilities, etc. Active Directory also constitutes a major part of the attack surface as it is one of the most desirable targets for cyber-attacks due to the important information it holds. The attack surface can be analyzed using diverse tools such as Endpoint Detection & Response tools, Extended Detection & Response tools, and Identity Threat Detection & Response tools. Gaining visibility throughout the network is the first step toward ensuring effective security controls.
- Track Incident Response Times: One of the best ways to measure security control efficiency is to track cyber security violations or incidents. This can provide effective insight into how well the security controls are configured. Tracking the time between infestation and the first report against the problem, response time taken to fix the issue, steps taken to mitigate the issue, and if the incidents have been recurrent helps provide information about security control’s health. Additionally, check if the outcomes of the mitigation steps were favorable or not. This allows a fair analysis of effectiveness of security controls.
- Check the Permissions: Assigning extensive access permissions to users can provide cyber criminals an opportunity to gain access to sensitive data. This makes it imperative to investigate the permissions granted to every user in the organization. Zero-Trust Architecture can help in mitigating this risk.
- Analyze Detection Alerts: Fake alerts can deter the cyber security personnel and cause delay in detecting actual threat. Tracking False Positive Reporting Rate (FPRR) helps in improving the configuration of detection tools to ensure more accurate threat alerts. Incorporating AI and ML capabilities in the detection tools can make the detection controls more sensitive.
