Can vulnerability be prevented
Security vulnerabilities, such as insecure direct object references, are a major problem for web applications. Fortunately, through fuzz testing and access validation techniques, IT security experts can detect and prevent IDOR vulnerabilities, helping safeguard applications from attack.
How are vulnerabilities managed
There are many ways to manage vulnerabilities, but some common methods include: Using vulnerability scanning tools to identify potential vulnerabilities before they can be exploited. Restricting access to sensitive information and systems to authorized users only. Updating software and security patches regularly.
Is Log4j fully patched
Log4j is patched, but the exploits are just getting started – The Verge.
