How to Secure Your Cloud Configuration
Your corporation’s cloud server could be susceptible to outside attacks if your IT department doesn’t understand how to secure and prepare your servers. Many enterprises don’t understand or even realize that they share the security responsibilities with their cloud service provider. Your cloud service provider is responsible for securing the underlying infrastructure, while you’re responsible for securing your cloud servers and specific workload that run in the infrastructure for IaaS.
Before starting your cloud server workload understanding proper configuration and cloud server security is necessary. Otherwise, your company risks the chance of alerting hackers to an easy mark. A recent cloud survey showed that a novice hacker can compromise your cloud server in just a few hours.
5 Import Considerations For Configuring And Safeguarding Your Cloud Servers
1. Verify tight hardening by internally verifying the master image
Cloud providers provide a catalog or marketplace where they provide master images. The master images have been advertised and vetted as pre-hardened but it is necessary that your IT department verify the master images before using them in your cloud servers. You need to understand that multiple instances will become the offspring from these images. Therefore, even a single vulnerability will become a much larger issue to rectify with repeated propagation. If using a pre-built AMIs both you and your cloud provide have to verify the AMIs before utilizing. Remember, never trust the master image and always verify the image internally against possible exposure.
2. Limit root access and monitor all API access
Always monitor the use of your server accounts, limit access to your servers, and pay special attention when giving access to accommodate APIs. Pay close attention to improper use of stolen, authorized credentials and always limit root access. You should enforce multi-factor authentication for all your access types on your servers. Also, for all API access, use time outs credentials and keep logs of all activity on your servers. This ensures that all activity on your servers is accounted for.
3. On your cloud servers disable all unnecessary services
Keep a lean profile on your cloud servers by disabling unnecessary ports and services. Look at how your servers are updated and determine if the updates should be automatic or though a process your IT department oversees to ensure against running unnecessary risks. If you don’t need the port or service, then don’t enable it. Guard against breaches by not activating unmonitored services.
4. Watch for drift on your cloud servers
Your IT department needs to manage drift from hardened configurations through tactfully patching. Many companies forego patching and solely rely on a refresh from completely new server images. Don’t introduce complications outside your maintenance window by creating an addition, slack with excess responsibilities and roles.
5. Continually watch for anomalies in your cloud server’s environment
Even when your IT security team is diligent about security hygiene, at times threatening situations still occur. You need a security team that can handle dynamically changing cloud conditions and elastic compute environments. When an anomaly suddenly appears a traditional security measure isn’t enough to handle a cloud environment and can weigh down your cloud flexibility.
