4.1 Apply common security techniques to computing resources This presentation will explore a range of proven techniques to safeguard computing resources, from establishing secure baselines to hardening a variety of devices and systems. Secure Baselines Establishing secure baselines is the foundation of an effective security strategy. This involves defining a consistent, hardened configuration across computing resources to minimize vulnerabilities and ensure a strong security posture from the ground up. 1. Analyze and define standard security configurations for various systems 2. Implement automated deployment of these secure baselines across the organization 3. Continuously monitor and maintain secure configurations to address evolving threats Establish Secure Configurations 1 Analyze Current State Thoroughly assess existing configurations across systems and devices to identify security weaknesses and opportunities for improvement. 2 Define Standard Baselines Collaborate with stakeholders to establish hardened, consistent security configurations that align with industry best practices and organizational policies. 3 Automate Deployment Leverage configuration management tools to streamline the rollout of secure baselines across the entire computing environment. Deploy Secure Configurations Distribute Configurations 1 Use configuration management tools to efficiently roll out the standardized security baselines across all computing resources. Validate Deployment 2 Implement automated checks to verify that the secure configurations have been properly applied and are functioning as intended. Monitor Ongoing Compliance 3 Continuously monitor the computing environment to ensure that secure configurations are maintained and any deviations are quickly identified and addressed. Maintain Secure Configurations 1 Monitor Compliance Continuously assess systems to ensure secure configurations are maintained. 2 Automate Updates Leverage tools to automatically patch and update systems with the latest security fixes. 3 Respond to Threats Quickly identify and address any deviations from the secure baseline. Maintaining secure configurations is an ongoing process that requires diligent monitoring, automated updates, and swift incident response. By continuously assessing systems, applying the latest security patches, and quickly addressing any deviations, organizations can sustain a robust security posture across their computing infrastructure. Hardening Targets Mobile Devices Workstations Implement strong access controls, enable Harden workstations by enforcing password encryption, and regularly update mobile policies, restricting local admin privileges, operating systems and apps to mitigate risks and deploying endpoint protection solutions from lost or stolen devices. to defend against malware and unauthorized access.
