Most of the industry have compliance and regulations from Government or Standard authority that very from industry to industry for maintain the security standard as part of their application services delivery to the end user and so the Security is the crucial decision factor before go live the application in most of the industry today.
I have seen the customers to validate the security issues in their app server image and application packages or build before they go live for production, Traditionally customer relaying on security scanning tools like Nessus, OpenVAS, OpenSCAP, Nmap, Wireshark, Metasploit, but the real challenges for customer start when they have large scale deployment and overhead to keep them operating to meet the Security SLA. Also With cloud world the more and more responsibility raised on the customer head.
Vulnerability scanning is a common compliance requirement (e.g., NIST 800-53 Rev.4 FISMA) for customers and a recommended security best practice for all organizations.
Customers face challenges with scanning due to:
1. Disjointed vulnerability scanning tools— often, customers will buy or license multiple tools for scanning instances, containers, and applications. The total cost can add up, leaving customers to choose between cost and security.
2. Lots of manual processes to correct vulnerabilities—Customers must deploy, configure, and upgrade agents on their fleets, with large operational pain, and the potential for misconfiguration due to human error.
3. Large volume of alerts with a high false positive rate—Vulnerability reports can overwhelm customers with “noise”. Too many false positive findings will cause customers to get lost in the volume or get accustomed to it. As a result, this can reduce the time to resolution for critical issues or even worse, these critical issues can go unacknowledged.
Vulnerability Scanning Service
Oracle Cloud Infrastructure Vulnerability Scanning Service (OCI VSS) is simple, prescriptive, and tightly integrated with the OCI platform. VSS is available to all OCI customers that have paid accounts at no additional cost. The scanning platform includes default plugins and engines for instance and container scanning.
The Scanning service can identify several types of security issues in your compute instances :
- Ports that are unintentionally left open might be a potential attack vector to your cloud resources, or enable hackers to exploit other vulnerabilities.
- OS packages that require updates and patches to address vulnerabilities
- OS configurations that hackers might exploit
- Industry-standard benchmarks published by the Center for Internet Security (CIS).
The Scanning service checks hosts for compliance with the section 5 (Access, Authentication, and Authorization) benchmarks defined for Distribution Independent Linux.
The Scanning service can scan individual compute instances, or it can scan all compute instances within a compartment and its subcompartments. If you configure the Scanning service at the root compartment, then all compute instances in the entire tenancy are scanned.
The Scanning service detects vulnerabilities in the following platforms:
- Oracle Linux
- Windows (no CIS benchmarks)
Oracle Vulnerability Scanning Service helps improve your security posture in Oracle Cloud by routinely checking hosts for potential vulnerabilities. The service generates reports with metrics and details about these vulnerabilities
High Level Architecture
Key Service Concept
Scanning parameters for a type of cloud resource, including what information to examine and how often.
One or more cloud resources that you want to scan using a specific recipe. Resources in a target are of the same type, such as compute instances.
Metrics about a specific cloud resource that was scanned, including the vulnerabilities that were found, their risk levels, and CIS benchmark compliance. The Scanning service uses a host agent to detect these vulnerabilities
Open ports that were detected on a specific cloud resource that was scanned. The Scanning service can detect open ports using a host agent, or using a network mapper that searches your public IP addresses
Information about a specific type of vulnerability that was detected in one or more targets, like a missing update for an OS package.
Integration with Cloud Guard
You can view security vulnerabilities identified by the Scanning service in Cloud Guard. Cloud Guard alerting can help customers reduce the time from detection to remediation.
