Introduction
CrowdStrike Security Policies are a set of rules and guidelines that can be used to configure and manage the CrowdStrike Falcon platform. These policies can be used to control a wide range of settings, such as which devices are protected, what types of threats are blocked, and how alerts are generated.
CrowdStrike Security Policies are an important part of any CrowdStrike deployment. By configuring and enforcing effective security policies, organizations can reduce their risk of cyberattacks and improve their overall security posture.
This article will provide a comprehensive overview of CrowdStrike Security Policies, including:
- The different types of CrowdStrike Security Policies
- How to create and manage CrowdStrike Security Policies
- Best practices for configuring CrowdStrike Security Policies
- Common CrowdStrike Security Policy use cases
Types of CrowdStrike Security Policies
There are two main types of CrowdStrike Security Policies:
- Device policies: Device policies are applied to individual devices or groups of devices. They can be used to control a wide range of settings, such as which devices are protected, what types of threats are blocked, and how alerts are generated.
- Sensor policies: Sensor policies are applied to the CrowdStrike Falcon Sensors that are installed on devices. They can be used to control a variety of sensor settings, such as how often sensors scan for threats and how data is collected from sensors.
In addition to these two main types of policies, there are also a number of specialized CrowdStrike Security Policies, such as:
- Application control policies: Application control policies can be used to control which applications are allowed to run on devices.
- Endpoint detection and response (EDR) policies: EDR policies can be used to configure how CrowdStrike Falcon Responds to threats.
- Threat hunting policies: Threat hunting policies can be used to configure how CrowdStrike Falcon OverWatch hunts for threats.
Creating and managing CrowdStrike Security Policies
CrowdStrike Security Policies can be created and managed using the CrowdStrike Falcon Console. The Falcon Console provides a variety of tools for creating and managing policies, such as policy templates, policy groups, and policy inheritance.
To create a new CrowdStrike Security Policy, simply navigate to the Policies page in the Falcon Console and click the Create Policy button. You will then be able to select the type of policy that you want to create and configure the policy settings.
Once you have created a new policy, you can assign it to devices or groups of devices using policy groups. Policy groups are collections of devices that share the same policy settings.
CrowdStrike Security Policies can also be inherited by child policies. This means that the settings of a parent policy will be applied to all child policies, unless the child policy overrides the parent policy setting.
Best practices for configuring CrowdStrike Security Policies
When configuring CrowdStrike Security Policies, it is important to keep the following best practices in mind:
- Start by creating a baseline policy. This policy should contain the basic security settings that you want to apply to all devices.
- Use policy groups to organize devices into logical groups and apply different policies to each group.
- Use policy inheritance to reduce the amount of time and effort required to manage policies.
- Regularly review and update your policies to ensure that they are effective and up-to-date.
Common CrowdStrike Security Policy use cases
Here are some common CrowdStrike Security Policy use cases:
- Block known malicious applications: CrowdStrike Security Policies can be used to block known malicious applications from running on devices. This can help to protect devices from malware, ransomware, and other types of attacks.
- Prevent unauthorized access to devices: CrowdStrike Security Policies can be used to prevent unauthorized access to devices. This can be done by configuring device passwords, enabling multi-factor authentication, and restricting access to devices based on location or user identity.
- Monitor devices for threats: CrowdStrike Security Policies can be used to monitor devices for threats. This can be done by configuring sensors to scan for threats on a regular basis and by generating alerts when threats are detected.
- Respond to threats: CrowdStrike Security Policies can be used to configure how CrowdStrike Falcon Responds to threats. This can be done by automating remediation tasks, isolating infected devices, and collecting evidence for forensic analysis.
Conclusion
CrowdStrike Security Policies are an important part of any CrowdStrike deployment. By configuring and enforcing effective security policies, organizations can reduce their risk of cyberattacks and improve their overall security posture.
