System security weaknesses are fixed through the vulnerability remediation process.
Vulnerability Remediation Process
Vulnerability Remediation | Step-by-Step Guide
- Discover: Detection of vulnerabilities is done through testing and scanning.
- Prioritize: Distribute the vulnerabilities and evaluate the risk.
- Remediate: Remove components, patch, or block the weaknesses
- Monitor: Outlook new vulnerabilities and weaknesses
The Vulnerability Management Life Cycle is intended to allow organizations to identify computer system security weaknesses; prioritize assets; assess, report, and remediate the weaknesses; and verify that they have been eliminated.
Organizations need to correct the vulnerabilities before detecting them. However, conventional remediation functionality depends upon the tools for scanning and communication.
Also, traditional Remediation can increase the MTTR(Mean to Respond) for longer than necessary by leaving the system full of vulnerabilities.
Penetration testing or vulnerability evaluation can lead to vulnerability remediation. These tests help you assemble the reports and figure out how to fix them.
Security teams can rank flaws by severity to patch the critical flaws first using the information. Then, after establishing a patch, developers can do one more scan and retest to substantiate the patch. In addition, retesting is a significant part of vulnerability remediation as some patches initiate new faults.
Fixation of vulnerabilities at the time of Remediation
Automatic vulnerability scanning detects the common vulnerabilities and gives a simple report. This report provides the minor threat categorization and generally sees all the possible vulnerabilities.
Vulnerability assessment systematically assesses your system by viewing the security weaknesses and vulnerabilities. This evaluation provides information to the defensive team to categorize, arrange and rectify faults. In addition, the test gives you a specific risk evaluation of exposures and finds bugs that self-activating scans miss.
During the discovery phase, enterprises can allocate significance dynamically via automatic scans or automatically. In addition, most enterprises use the general vulnerability scoring system(CVSS) to convey the vulnerability’s extremity and features. Moreover, the CVSS scoring system measures extremity based on the attack point, difficulty, and effect.
Enterprises primarily allocate vulnerability revelation to staff members who control a specific system. For example, Application vulnerabilities are fixed by the development teams, while the database-connected vulnerabilities fix by the Database administrators.
Some of the common vulnerabilities out there are:
- Unpatched operating systems
- SQL Injection
- Weak account credentials
- Cross-Site Scripting (XSS)
- Insecure Direct Object References (IDOR)
- Device error
Reclamation time varies as per the vulnerabilities effect, and take the necessary steps to fix them. Enterprises must carefully propose Remediation because patches can need to break or have aimless consequences. However, development teams might deliver a temporary patch to give a bypass when they require more time to install the vulnerability properly.
Vulnerability Management systems generally have numerous options for anticipating and exporting vulnerability information. However, the security team mainly depends on a live alert system to detect the threats and log collection for the deep manual evaluation.
Observing might be escorted to retesting, where scanning of the specific system is done again by the team. However, if the systems cling to adherence standards, like HIPAA, the development team can create reports documenting the patching methods and describing ongoing adherence.
