基于模糊測試的軟件漏洞檢測技術(shù)研究基于模糊測試的軟件漏洞檢測技術(shù)研究

摘要：隨著軟件系統(tǒng)的復(fù)雜度不斷提升，軟件漏洞已經(jīng)成為阻礙軟件安全的重要因素。因此，如何對軟件進(jìn)行充分的安全性檢測已經(jīng)成為當(dāng)前研究的熱點。模糊測試作為軟件安全檢測的一種有效手段，已經(jīng)成為研究熱點。本文針對模糊測試技術(shù)在軟件安全性檢測中的應(yīng)用做了詳細(xì)的探討，介紹了模糊測試的相關(guān)理論和模糊測試技術(shù)的分類、模糊測試的優(yōu)缺點，以及模糊測試和其他測試方法的比較和綜合運用，最后闡述了模糊測試在實際應(yīng)用中的問題和未來的研究方向。本文通過綜合性的論述，為軟件安全性檢測提供了另一種有效的手段。
