During a security assessment, why is it recommended to remove extraneous identifying information from service banners?

• A. To comply with vendor license
• B. To reduce information exposure to attackers
• C. To improve performance
• D. To enable remote login

Answer: (B)

Service banners disclose what software and version are running, which helps an attacker fingerprint systems and identify applicable exploits. Removing extraneous identifying information from banners limits what is exposed during reconnaissance, making it harder for an attacker to tailor an attack to a specific vulnerability. That’s why it’s recommended in security assessments to minimize or hide banner details. It’s not about license compliance, performance improvements, or enabling remote login.
