چکیده مقاله :
شرکت‌ها و سازمان‌های بزرگ در دنیای امروز، تمایل بسیاری به استفاده از سرویس‌های ETI جهت ذخیره‌سازی و انتقال داده‌های خود دارند. افزایش نرخ استفاده از سرویس‌های تحت شبکه، افزایش مخاطرات و حملات به داده‌ها در زمان ارسال و دریافت و ایجاد محیطی امن برای انجام خدمات در بستر شبکه ابر، چالشی بزرگ را در حوزه سیاست امنیتی مطرح می‌کند. بخش مدیریت امنیت بروکر در شبکه ابر، تأثیر زیادی در مدیریت و متعادل‌سازی متغیرهای امنیت، کارایی و دسترس‌پذیری دارد. این مقاله سعی دارد با ارائه چهار فاز امنیتی بر روی داده در زمان ارسال و دریافت بین مشتری و CSP، ضمن پیشگیری از خرابی داده در زمان سرقت، میزان بازدهی متغیرهای کارایی، متغیر دسترس‌پذیری و شاخص رضایتمندی مشتریان را بررسی نماید. نتایج ارزیابی بر روی سه مدل آزمایشی نشان می‌دهند میزان جرائم تخصیصی سیستم به میزان 41/61% کاهش و شاخص رضایت مشتریان تا 67/60% افزایش می‌یابد.
Today, various clients use the cloud to transfer Thing by Internet (ETI). Many companies and organizations are persuaded to use the cloud utilities in secure environment. Beside of this technology is becoming popular, the risks and attacks on data are increasing. Ultimately, a security broker management in cloud services tries to balance security, performance, and availability features availabilities. This paper tries to increase the customer satisfaction index by creating 4 phases of security on the data process during transporting between the customer and the Cloud Service Provider (CSP), while increasing efficiency and availability. Tables and graphs show that the amount of the system allocated penalty is reduced by 61.41% and the customer satisfaction index has increased by 60.67%.
