CVE (Common Vulnerabilities and Exposures)

• CVE is a public database that provides information on known vulnerabilities in software and hardware systems.
• It helps security professionals identify, track, and manage vulnerabilities, offering a unique identifier (CVE ID) for each vulnerability.
• The CVE database enables consistent identification of vulnerabilities, making it easier to monitor and address security risks across different platforms.

DNS Resolution Issue and Fix

If you can ping 8.8.8.8 (Google's DNS) but cannot access www.google.com, your system's name resolution is likely the issue. Here’s how to fix it:

1. Check

   Copy

   /etc/resolv.conf

   :
   • Open the file to verify if the nameserver is configured correctly.
   • If not, you can manually add a nameserver.

2. Add a new nameserver:

   • Open

     Copy

     /etc/resolv.conf

     and add the following entry:

     bashCopy
     nameserver 8.8.8.8
     

This should resolve the issue and allow you to access websites by name.
