Consider using tables to present quantitative data, such as the number of vulnerabilities detected and their severity levels.
Vulnerability Type | Count | Severity |
|---|---|---|
SQL Injection | 5 | High |
Cross-Site Scripting | 3 | Medium |
Weak Passwords | 10 | Low |
Identifying Security Gaps
Once the data is compiled, the next step is identifying where the security gaps lie. This involves analyzing the compiled data to pinpoint weaknesses in the network. Common gaps include outdated software, misconfigured firewalls, or insufficient encryption. Creating a list of these gaps helps prioritize which issues need immediate attention.
Outdated software versions
Misconfigured security settings
