A vulnerability is a flaw in a computer system that a criminal or hacker can exploit to get unauthorized access to systems, data, or applications.

Many computer systems have flaws in their software, hardware, firmware, and other infrastructure. If a flaw could potentially allow an attacker to compromise a system, either to access data or otherwise damage the business, it becomes a vulnerability. Attackers use special tools to exploit vulnerabilities and get access to your applications and data. There are various ways to identify and mitigate system vulnerabilities.
Vulnerability Scanning and Assessment
Vulnerability scanning software will analyze various aspects of an IT ecosystem to identify known flaws and provide solutions to patch vulnerabilities. They use a database of known system issues to detect and report on flaws.
Regular Patching and Maintenance
Hardware, software, and system manufacturers will issue maintenance patches when they identify possible vulnerabilities. IT teams should prioritize installing these patches to reduce the potential attack surface a hacker would have access to.
Penetration testing is a technique that copies the various ways hackers would attempt to access IT systems and data. The people who carry out penetration testing will attempt to exploit vulnerabilities and let an organization know about the gaps that need to be closed.
Authentication and Authorization
Properly identifying users when they attempt to login is a first line of defence for cybersecurity. Robust authentication techniques can keep criminals from exploiting deeper vulnerabilities.
Together, these techniques will significantly reduce a company’s vulnerability and exposure.
