Vulnerability assessment enables recognizing, categorizing and characterizing the security holes, known as vulnerabilities, among computers, network infrastructure, software, and hardware systems.
If vulnerabilities are detected as part of any vulnerability assessment then this points out the need for vulnerability disclosure. Such disclosures are usually executed by individual teams like the organization which has discovered the vulnerability or Computer Emergency Readiness Team (CERT). These vulnerabilities become the key source for malicious activities like cracking the websites, systems, LANs etc.
Steps for Assessing the Security of Any Network
1. Identify and realize the approach of your company or industry like how it is structured and managed.
2. Trace the data, systems, and applications that are exercised throughout the practice of the business
3. Examine the unobserved data sources capable of allowing simple entry to the protected information
4. Classify both the virtual and physical servers that run the essential business applications
5. Track all the existing security measures which are already implemented
6. Inspect the network for any vulnerability
Vulnerability scanners automate security auditing and can play a vital part in your IT security by scanning your network and websites for different security risks. These scanners are also capable of generating a prioritized list of those you should patch, and they also describe the vulnerabilities and provide steps on how to remediate them. It is also possible for some to even automate the patching process.
