セキュリティ アナリストが、ネットワーク管理者のワークステーションで脆弱性スキャンを実行します。ネットワーク管理者は、会社の SSO Web ポータルへの直接管理アクセス権を持っています。脆弱性スキャンにより、ユーザーのブラウザー、OS、電子メール クライアント、およびオフライン パスワード マネージャーに対して同様に高い CVSS スコアを持つ技術的な脆弱性が明らかになります。セキュリティ アナリストが最初にパッチを適用する必要があるのは次のどれですか。
正解:C
The browser is the application that the security analyst should patch first, given that all the applications have equally high CVSS scores. CVSS stands for Common Vulnerability Scoring System, which is a method for measuring the severity of vulnerabilities based on various factors,such as access conditions, impact, and exploitability. CVSS scores range from 0 to 10, with higher scores indicating higher severity. However, CVSS scores alone are not sufficient to determine the patching priority, asthey do not account for other factors, such as the likelihood of exploitation, the exposure of the system, or the criticality of the data.
Therefore, the security analyst should also consider the context and the risk of each application when deciding which one to patch first. In this case, the browser is likely to be the most exposed and frequently used application by the network administrator, and also the most likely entry point for an attacker to compromise the system or access the SSO web portal. Therefore, patching the browser first can reduce the risk of a successful attack and protect the system and the data from further damage. Verified References:
