What is CVE? [Exposição e Vulnerabilidades] – Antivirus and Security – Tecnoblog

Once discovered, vulnerabilities can become dangerous for attackers. hackers. See below, what is CVE and how this international registry of threats and vulnerabilities of softwares, aimed at protecting the systems as a whole.

The definition of CVE

A sigla CVE — Common Vulnerabilities and Exposures — is a log list of threats and vulnerabilities identified in softwares. Usually, when referring to CVE, the person ends up indicating a specific ID number that each record on the platform has, organizing the catalog.

Security alerts issued by vendors or researchers almost always mention at least one CVE ID. CVEs help IT professionals coordinate their efforts to prioritize and address vulnerabilities, making computer systems more robust and secure.

How does it work and who is behind CVE?

The CVE program is overseen by the Miter corporation, with funding from the Cyber ​​Security and Infrastructure Agency (CISA), part of the US Department of Homeland Security.

CVE entries do not include technical data or information about risks, impacts, and fixes. These details appear in other databases, including the US National Vulnerability Database (NVD), the CERT/CC Vulnerability Notes Database, and various lists maintained by vendors and other organizations.

Across these different systems, CVE IDs provide users with a reliable way to recognize unique vulnerabilities and coordinate the development of security tools and solutions. The Miter corporation maintains the CVE List, but a security hole that becomes a CVE entry is often submitted by organizations and community members as a primary identification.

How important is your security?

Users concerned about exposing their systems to failures or professionals specialized in cybersecurity, need to anticipate information. The role of the CVE is so great in alerting that even hackers malicious actors search for information and create new attacks.

The registry is very broad, so some pillars are important to guide the user who will do his research on CVE.

Know the systems you use

Just because a CVE exists doesn’t mean the risk applies to your specific environment and jobs. Read each CVE and understand the scenario, defining that it fully or partially applies to your operating system, application, modules and configurations of your systems.

Manage vulnerabilities

Management is a repeatable process to identify, classify, prioritize, remediate, and reduce vulnerabilities. This means understanding how a risk would apply to the organization or system to properly prioritize any examples that are outstanding and need more active action.

Communication

Whether internally, in the case of organizations, or with your friends who may suffer from the same threat, be ready to communicate.

Obviously, in the case of companies this must be prioritized, CVEs will affect the organization’s systems, both because of the vulnerabilities and any possible downtime needed to resolve them.

Communicate and coordinate with your internal peers and share vulnerabilities with any central risk management function in the organization.

Now we know what CVE is and its importance for preventing vulnerability issues. Just get into the habit of checking for new updates, there are many entries with new CVE IDs important for each case. Good luck.
