Deploying a process of constant monitoring of IT vulnerabilities in your business may sound like a big challenge at first, but it will guarantee a much more streamlined and efficient management of information security in the long run.

Why?

Companies that have already implemented such a process, build a proactive stance on information security. By being able to map breaches, these companies are able to prevent risks. That is, they are not reactive, responding to threats only when an incident happens.

Vulnerability management makes it possible to establish routine practices to investigate possible breaches within the company’s internal context and to act proactively to correct them.

One of these practices, and a fundamental step the vulnerability management, is the prioritization of risks. A company that is already familiar whit this concept knows that there are different levels of vulnerability and that it is not possible to fix them all at the same time. The process of classification and prioritization is very important to build a feasible action plan (to correct and/or mitigate risks).

BLOCKBIT has a vulnerability management technology (BLOCKBIT VCM), which not only scans your environment, but also correlates the violations found with industry standards. This information helps to establish criteria to classify each identified vulnerability. These criteria are based on the level of risk and the availability of exploit tools, in a way that guide the correction process.

Let’s now consider, in the context of this tool, how vulnerabilities can be sorted:

1. Asset

One of the most important criteria is to understand how relevant each network asset is. For example, a company may identify different vulnerabilities in:

  1. a server that serves the entire enterprise;
  2. a local device of a C-Level executive;
  3. a web application.

Which of these cases represent a possible immediate impact? The tool is able to deliver this information from settings established in accordance with company policies and thus collaborates to optimize your workflow.

 

2. Risk Score Average

Another criterion is the score calculated based on:

  1. the risk of the vulnerability identified in the scan; compared to
  2. the level of importance of the asset.

This correlation will “create a queue” of risk level for each vulnerability. In the case of BLOCKBIT VCM, the information of each violation found in the scan is evaluated from based on CVSS (Common Vulnerability Scoring System).

 

3. Exploits

Vulnerabilities are considered to have the greatest impact when an exploit is available (click here and remember what is an exploit).

Even though your team identify different breaches in the network environment, if there is no tool able to exploit them, there is no urgency in their correction. This does not mean that the vulnerability should not to be addressed in a work plan. But, the error mitigation schedule can be more flexible, saving staff time to work first on those breaches forwhich a existing exploit have been confirmed.

 

4. CVE

Finally, the tool adopts CVE (Common Vulnerabilities and Exposures)a catalogue that maintains a global public system to report new vulnerabilities, to work as intelligence source to define the level of risk.

The number of threats is constantly increasing, and therefore the volume of vulnerabilities often varies. So, it may seem that the challenge to sort and prioritize is much higher, taking a lot of time of your team.

But this is one of the greatest advantages of adopting a platform to manage your vulnerabilities. With recurrent scans, your company will be constantly fed with information of how the resources comply with internal security policy or market rules, as well as receive reports that make it easier for the team to work, saving time and granting agility to decision making.
