    2017年我國互聯網網絡安全態勢如何?

    作者: 來源: 日期:2018/5/15 17:16:26 人氣:83 加入收藏 評論:0 標簽:


    互聯網網絡安全存在眾多威脅


    從國家互聯網應急中心對于我國2017年互聯網絡安全的監測數據來看,主要分為六方面。首先,惡意程序方面,檢測發現2017年境外控制服務器大約有3.2萬個,同時,境內感染計算機惡意程序達到1256萬臺,較2016年下降了26.1%。感染計算機惡意程序中,遠程控制木馬的數量最多,達到了71.65%,僵尸網絡木馬占比20.3%。


    據云曉春介紹,他們每個月都要定期對互聯網上僵尸木馬程序進行清理,來保證互聯網上網絡安全的環境。去年,一共治理了664個控制規模較大的僵尸網絡。


    在安全漏洞方面,國家互聯網應急中心成立了一個國家信息安全漏洞共享平臺。云曉春介紹稱:“我們是國內最大規模的國家級漏洞庫,收錄了通用軟硬件漏洞15955個,同比上漲了47.4%。收錄的漏洞里面涉及到谷歌產品的漏洞是最多的,達到了1133個,占整個收錄漏洞的7.1%。同時我們在漏洞庫中建立了4個子漏洞庫,包括移動互聯網子漏洞庫、電信行業的子漏洞庫、電子政務的子漏洞庫等。在2017年我們所收錄的聯網智能設備安全漏洞達到了2440個,同比增長118.4%。涉及到的產品包括家用路由器、網絡攝像頭、會議系統,這些漏洞類型包括了命令執行、文件上傳等等。”


    此外,拒絕服務攻擊也是很重要的一點。反射放大攻擊中的主要流量是來自于境外,通過對攻擊進行分析發現有一個非常大的特點,發起攻擊的次數呈現密集分布的特點,實際上是少量攻擊資源發起攻擊次數。


    在網站安全方面,去年一共監測發現仿冒頁面4.9萬個,下降72.5%。全年共協調處理頁面2.5萬個,涉及移動互聯網的頁面7000多個。被植入后門的網站數量2.9萬個,同比下降64.6%。涉及IP地址約2.4萬個,90.6%位于境外。在網頁篡改方面,發現境內被篡改網站2萬個,同比上漲20%。被篡改政府網站有618個,同比上漲32.3%。


    工業互聯網作為網絡強國戰略,也面臨非常大的潛在威脅。通過檢測發現200例左右聯網公眾設備或者平臺存在著嚴重的漏洞隱患。此外,針對互聯網金融,國家互聯網應急中心也建立了相應的互聯網金融分析平臺,對國家互聯網安全進行宏觀監測。2017年抽取1000家互聯網金融網站進行安全評估監測,發現了嚴重的用戶數據泄露風險。



    2018年網絡安全需關注五大方面


    首先,在2018年,對于個人信息和重要數據保護方面會變得非常重要。在今年歐盟推出了GDPR,給全世界的公司提出了非常大的挑戰。在GDPR里明確提出了,只要是歐盟的公民,即使他在中國,他的數據你也是不能隨便進行獲取的。從整個態勢上來看,全世界各國對于公民隱私保護提到了前所未有的高度。


    第二,云曉春認為在2018年,安全漏洞信息保護將會成為非常重要的問題。因為漏洞本身目前被大家認為是一個國家的戰略性資源,每一年我們也都會發現大量的新漏洞。在這種情況下,漏洞到底按照怎樣的方法來披露,這會成為一個很重要的問題。


    《網絡安全法》26條規定,向社會公布系統漏洞應當遵循國家有關規定。沒有原則的往外公布,可能最后對廠商、企業,包括對個人都會造成很大的危害,甚至可能危害國家的安全。所以說到底如何來進行漏洞的信息保護、披露,在今年會成為非常重要的問題。


    第三,物聯網設備面臨著網絡安全威脅加劇。現在萬物互聯,現在越來越多的物聯網呈現在我們的家庭和生活中,當IPV6和5G推動,我們相信會大大增快物聯網發展。當物聯網設備越來越多的時候,安全問題會變得越來越明顯。


    第四,數字貨幣會引發越來越多的更復雜的網絡攻擊。目前,有很多針對各個平臺上推出的專門的挖礦木馬,在今年數字貨幣的安全問題會成為熱點的問題。


    第五,云曉春講到,在2018年應該關注的就是人工智能運用在網絡安全領域的熱度會持續上升。人工智能在網絡安全的熱度不只是用在防范,攻防也是很重要的一部分。
