Cloud Security Control Types
While you can implement several security controls in your organization, most fall into four categories: deterrent, preventive, detective, and corrective. The best security control approach in cloud security includes all of these types to ensure maximum protection for your organization.
Deterrent Controls
Deterrent controls in cloud security discourage harmful actors by indicating the presence of robust security measures and warning about the repercussions of illegal activities. They serve as a barrier, causing attackers to reconsider targeting a system. While they don’t prevent attacks, they can impact decision-making by highlighting potential hazards.
Examples include warning banners on login screens, background checks on personnel, legal disclaimers, and visible security measures such as data center cameras. Deterrent controls help to create a more secure cloud environment by making it less inviting to potential attackers. Combined with other cloud safeguards, these measures are especially effective at increasing security awareness and discouraging suspicious conduct.
Preventive Controls
Preventive cloud security controls try to increase defenses to prevent assaults from occurring. They eliminate vulnerabilities, protect inactive ports, and provide robust user authentication. Use preventive controls to restrict access and secure data, reducing the attack surface. These controls secure sensitive information in cloud environments.
Some examples of preventive controls are multi-factor authentication, encryption, access controls, and network segmentation. These ensure that only authorized individuals have access to essential systems, thus lowering the risk of data breaches and unauthorized activity. These controls play an important role in a comprehensive cloud security strategy because they address potential vulnerabilities ahead of time.
Detective Controls
Detective controls in cloud security intend to identify and react to real-time security incidents. They work by constantly monitoring the cloud environment for unusual activity, assisting enterprises in identifying and responding to possible risks. Use detective controls to supplement preventive measures and enable quick discovery of breaches.
Intrusion detection systems, cloud monitoring, and log analysis tools are some examples of this type of control. These provide visibility into security occurrences, allowing for faster reactions and less harm. Detective controls are critical for discovering threats that may bypass other defenses and ensuring that security incidents are addressed quickly to reduce risk.
Corrective Controls
Following an attack, cloud security’s corrective procedures kick in to limit damage and restore regular operations. They perform actions such as reboots, backups, and unplugging hacked systems. Use corrective controls to respond swiftly to breaches and mitigate their consequences.
Corrective control incorporates patch management, incident response plans, and backup recovery methods. These controls are critical for reducing the effects of security incidents, allowing businesses to recover quickly and avoid future assaults. Corrective controls are an essential component of a resilient cloud security plan. These ensure that firms may resolve breaches while maintaining operations with minimal disruption.
