Vulnerability management is a proactive approach that mitigates or prevents the exploitation of IT vulnerabilities that may exist in corporate critical systems or network. This approach involves a number of steps that include identification, classification, remediation, and mitigation of numerous vulnerabilities.
According to CVE Details Report, 15703 vulnerabilities have been identified in 2018, compared to 14714 in 2017.
In fact, vulnerability management involves maintaining the security of all corporate systems and it is a difficult and time-consuming task. Therefore, automating this task is of paramount importance for organizations. Doing so requires security orchestration to play its crucial role. The following section describes how security orchestration helps in automating vulnerability management.
Role of Security Orchestration in Automating Vulnerability Management
To automate this process, security orchestration uses “vulnerability management playbook.” First of all, the security professionals utilize vulnerability management tool like Centraleyezer, Cryptosense, Patch Management Plus, and so on. This tool provides information to the playbook regarding systems and vulnerabilities. After that, the playbook further investigates if the vulnerability is actual, its expected consequences, and remediation process if requires. For this purpose, the playbook operates in collaboration with the vulnerability management tool.
When a vulnerability identifies, its information is added to incident data and Incident Response team is intimated about this incident. Before remediation, it is also needed to check the gravity of the incident. For example, the incident may involve a single phishing Email or may incorporate a Malware Attack that causes a huge breach of employees’ sensitive information.
Once the gravity of the incident is calculated, the remediation process is initiated, which is indeed a final step of automating vulnerability management. In this step, the final and manual control is transferred to the incident response team who takes proactive steps to eliminate or mitigate the attack.
Evaluating vulnerability reports, such as the history of the affected system, and identifying of system owner is a daunting task. However, automating this task can reduce repetitive work and enable the security team to concentrate on other important issues.
Why Automation of Vulnerability Management is Critical?
Automating vulnerability management using a security orchestration platform ensures that a security team is mindful of new vulnerabilities in its IT environment. Doing so helps them proactively analyses the vulnerable host in order to confirm that there is no evidence of exploitation. If any porous hole is identified, then additional security measures are implemented and current vulnerability is mitigated or eliminated altogether.
