Vulnerability management is a continuous process that protects your systems from data breaches and cyberattacks. Vital programs include processes for discovery, prioritization, action, re-assessment, and improvement.
Security vulnerabilities make it easy for malicious actors to steal your sensitive data or disrupt your business operations. Many organizations face colossal payouts and damage their reputation over security incidents they could have prevented with better vulnerability management.
Vulnerability Assessment
Vulnerability assessments help organizations identify weaknesses attackers can exploit. These weaknesses are commonly found in software or hardware components that make it possible to breach applications, systems, and networks. They are introduced into the system in many ways, including coding errors, misconfigurations, and insecure deployments. Attackers may leverage these flaws to steal information, wreak havoc, or interfere with operations.
This typically involves using a tool to identify assets, run automated tests, and detect operating systems, software, ports, and service flaws.
It prioritizes vulnerabilities based on severity, potential impact, and exploitability to focus efforts on the most critical issues. This step is often done by creating a vulnerability management database with a centralized view of identified vulnerabilities.
It is developing a remediation plan to fix vulnerabilities that cannot be remediated (and reduce risk). This is usually a joint effort between development, operations, and security teams in DevSecOps.
Vulnerability Remediation
The remediation procedure seeks to prevent hackers from accessing your private information by eliminating vulnerabilities. This includes patching, upgrading, or turning off a vulnerability until it poses minimal risk to your systems.
Remediation can reduce attackers’ time to exploit weaknesses and impact your business operations. This is especially critical to preventing attack escalation and lateral movement within the network, which can cause severe financial and reputational damage.
The first step in the remediation process involves discovering vulnerabilities by scanning your entire IT environment, including traditional IT, cloud services, mobile devices, and IoT. This discovery should be performed continuously to get real-time visibility into your IT ecosystem and decrease vulnerability exposure. The second step is prioritizing scanned vulnerabilities. This can be done through a vulnerability management solution or by creating a custom scoring system to rank threats by severity for your business context.
Vulnerability Mitigation
Vulnerability mitigation involves reducing the risk of exploited vulnerabilities. It can be accomplished by implementing several tactics to assist firms in mitigating yearly breaches, such as consistent patching and personnel training.
A successful vulnerability management (VM) program must have a straightforward methodology to inventory and prioritize vulnerabilities. While static methods like CVSS can help, they don’t account for context or the potential impact a vulnerability could have if left unremedied.
Once vulnerabilities have been identified and prioritized, a security team should implement a mitigation plan. This may include deploying patches, creating policies to prevent misconfigurations, and ensuring that 3rd party hardware is vetted. The process should also provide visibility and reporting to meet critical metrics. This helps to uplift the program and demonstrate a return on investment to stakeholders. It can also enable a transition from vulnerability management to cyber resilience and align the organization with industry security frameworks.
Vulnerability Reporting
With new vulnerabilities discovered daily and bad guys that don’t take a day off, continuous vulnerability scanning and reporting is essential to security operations. Vulnerability management helps IT, and executives track risk and prioritize fixes while showing how adequate security controls are in reducing threat levels.
Vulnerability reporting should include the overall scan results and a detailed report for each vulnerable asset. For each, include information on how the vulnerability was detected, what systems were affected, and the impact on business functions. It would help if you also described the root cause, how to fix it, and a status update on what has been done to resolve the vulnerability.
A good vulnerability report should also note the current state of each vulnerability, which can be illustrated with a color-coded risk score or other metric that is easy for IT and executives to understand. It should also provide reporting on the number of open versus closed vulnerabilities so progress can be tracked and the success of remediation efforts can be celebrated.
