Everyone is concerned about security, especially when it comes to data, and the thought of a breach or a cyber-attack is scary. But how do you protect your organization from these types of problems?
As industry expert Rootshell Security explains (https://www.rootshellsecurity.net/vulnerability-management/), the vulnerability management life cycle is a framework that shows the steps you must take to protect your organization from security incidents.
In this post, we’ll discuss each of these steps and demonstrate how to implement them in your organization.
Discovery of Assets
Awareness of the situation’s extent is the first step in the vulnerability management life cycle. This involves mapping out all the network’s assets for vulnerabilities, including OS, software and their existing patches, hardware and open services. The important goal here is to establish a network baseline that can be used to discover new security gaps on a regular basis. Outliers are easier to spot if you have a baseline. It’s here where most flaws can be found.
After gaining a baseline, vulnerability scans and tests are conducted. All of the company’s assets must be considered. There should be no device left unchecked.
Prioritize Vulnerabilities
After creating a baseline and determining the vulnerable assets, that’s when the real work begins. In this stage, three things take place:
- Asset valuation – Pre-work pays off here. The value of assets is determined according to the importance they play in a company’s operation. Top priority should be given to hardware and software that supports the most critical business functions.
- Assess each asset’s risk – Examine how much each asset is exposed to danger. This requires some in-depth investigation and research to reach conclusive results.
- Add Threat Context – Here, an in-depth threat intelligence examination is conducted with the help of endpoint security tools to ensure satisfactory results on the already determined and prioritized risk levels.
Assessment
After the assets have been appropriately categorized, a thorough assessment can be carried out. Evaluation of the risks and vulnerabilities of the system is done to determine the best course of action.
Vulnerability scans and testing are undertaken based on threats and the value of the company’s assets. This includes the operating system, web server, web application and any other service that may need to be tested.
Checks are done to see if the appropriate measures are being taken to ensure the safety of the assets, find any mistakes that may have been made in the configurations and determine if there are any human errors, and, if present, pinpoint them. Validating the results of the tests and scans is done once completed.
Reporting
Each piece of information gathered has to be documented into a unique report outlining the most critical security flaws to address first. This acts as a guideline for responding quickly and effectively to any issues that may arise.
Step-by-step instructions for troubleshooting should be included in the guide. This is done to reduce the chances of these vulnerabilities re-emerging and posing a significant security threat.
After that, a security plan needs to be established, and every potentially questionable activity that may surface as a direct result of the weaknesses needs to be kept an eye on.
Remediation
In most cases, remediation entails replacing susceptible hardware or software, altering configurations, installing patches or isolating susceptible systems to safeguard other components. It may also include bringing employee training up to date, deleting user accounts and introducing new technology to handle some manually performed IT tasks.
Every network device must be routinely monitored and recognized to stay ahead of the constantly expanding and morphing dangers. It is imperative to deal with high-risk vulnerabilities within a month or before your following scheduled monthly scan, whichever comes first. As for the moderate risks, they should be remediated within 90 days and 365 days for the low risks.
Verification
After a security vulnerability has been identified and patched, it is necessary to carry out routine checks to ensure that it has not reoccurred. In addition to this, it is essential to perform a new assessment of how successful the procedure was.
Verifications ensure security threat exposures are minimized to the lowest level possible, reducing the number of attack surfaces hackers can utilize to launch an assault on a company’s network. Also, verifications help ensures the previous stages of the verification management lifecycle have been successfully implemented.
So what are the Steps in the Vulnerability Management Life Cycle?
We live in a world plagued by an epidemic of cyber attacks. Therefore, staying ahead of attackers through vulnerability management has become crucial. The vulnerability management lifecycle helps secure and monitor systems networks and assets to ensure they are no security gaps, thereby reducing the number of potential cyber attacks and their impact.
