雲原生和“人造”雲安全產品之間的 10 個差異

For IT and security teams with limited staff and tight budgets, cloud-native software-as-a-service (SaaS) security products offer tremendous value. Some CIOs have even mandated that new security tools be delivered in the cloud where possible. Some vendors with older on-premises products have tried to sneak in their products by claiming they are now “in the cloud,” but the truth is that that is a façade.

Let’s call these products “faux” cloud security to contrast against products that are truly “cloud native.” Vendors of faux cloud products hope that with a little marketing smoke and mirrors, they can use some “cloudy” language and potential buyers will not know the difference. When we say faux cloud, technically speaking, we mean that the vendor is just allowing the customer to host their on-premises product in the customer’s public cloud account. This means the customer still must install, configure, deploy, maintain, update, and eventually decommission that product.

In other words, you as the customer must do all the work. The only “cloud” aspect of this arrangement is that you can do all the work on a server you are renting (that is, paying for) from AWS, Azure, Oracle, Dell, etc.

Faux Cloud Security in the Real–World

A real-world example of this software sleight-of-hand is Cisco’s Internet Security Engine (ISE). Cisco delivers ISE as a virtual appliance to handle network access control (NAC) – a critical component of any effective cyber security stack. As of ISE’s latest version, a customer can deploy the software in their own AWS or Azure accounts.

That is the long and short of it, however. The well-known challenges of setting up ISE – or any other network security appliance – remain. It is difficult to get your ISE server configured properly, ensuring it communicates with all your network equipment, even after having committed over 1,200 pages of ISE documentation to memory.

Cloud Native Reduces the Hassles

In contrast, a truly cloud-native solution allows the customer to sign up through a web page, configure as needed, and move on – the application just works out-of-the-box. Period. Now, that’s the easy part. As your organization consumes a cloud service, it does not have to concern itself with nagging issues and questions along the way common with on-premises software (e.g., How do we roll out patches and upgrades? Is there a security vulnerability in the operating system? Who is handling system backup?). You, as the end-user, have historically been responsible for these items with legacy on-premises software.

Portnox CLEAR NAC-as-a-service is cloud-native – “born in the cloud” as it were. To deploy CLEAR, a customer just needs to visit the sign-up page, enter their wireless controller information, configure the RADIUS settings on the network device, and CLEAR will begin enforcing policies. Portnox customers have done this in as fast as 30 minutes from start to finish. As is true of cloud-native solutions in other domains, customers can see value in minutes, not days, weeks, or even months. No complexity. No hassle.

Knowing the Difference Before You Commit

As a potential customer, how can you distinguish cloud-native from faux cloud security software?

There are a few telltale signs. The table below summarizes some of the most salient differences. When you evaluate a new vendor, be sure to ask questions such as who is paying for the infrastructure? Who is responsible for updates and upgrades?

Cloud NativeFaux Cloud
InfrastructureProvided, paid, and managed by the vendor; mostly invisible to anyone utilizing the serviceProvided, paid, and managed by you through your own AWS or Azure account
ImplementationQuick time to value; much of the work is invisible to youDepends on the complexity of the app, but it is your responsibility to do the work or pay someone else to do it
PricingSubscription with lower up-front costPerpetual license with expensive up-front cost that are amortized over time.

(Note: many vendors are moving away from perpetual licensing for on-prem or faux cloud products, but as they do, their customers are getting the worst of both worlds – paying more annually while still being responsible for on-going maintenance of the product)
Total Cost of OwnershipThe price of the product reflects the genuine cost of ownershipThe price of the product is only one (and sometimes only a small) part of the total cost that is reflected in the staff time and public cloud expenses; in many instances, you may not even know what it is going to cost you until it is too late
Vendor Lock-InEasy to switch to another vendor should your business needs changeExpensive license, deployment and maintenance costs make switching prohibitive, often for years
AccessAccess anywhere via browser with internet connectionOn-premises model often requires access via VPN

(Note: what happens when there is a problem with your solution and your VPN is configured to use your on-premises system? Sounds like someone is driving into the office!)
ScalabilityAutomatically scales with usageCustomer must increase capacity to keep up with usage
UpdatesVendor regularly updates the underlying components such as servers, databases, etc. This process will often be invisible to you.You are responsible for ensuring that the entire tech stack – components, databases, servers, network – is updated with the latest patches
UpgradesYou seamlessly and transparently reap the benefit of new features, enhancements, and other improvements with zero effortAny upgrade requires you to install, test, and then deploy the upgrade in production, often during nights and weekends in case something goes wrong
AccountabilityThe vendor takes ownership of the uptime and security, performance, and availability of the serviceApart from the infrastructure as a service, you are on the hook for the performance, health, security, and availability of the solution, lock stock and barrel

2022年擺脫十大網路安全壞習慣

2021年依舊是網路犯罪頻繁的一年,僅僅在上半年,就有近190億筆訊息被曝露,盤點十大網路安全壞習慣,ESET資安專家提醒保持警惕,積極主動去改善,相信您就可以擁有安全無虞的2022 年。

1.沒有定期更新
電腦及設備上的操作系統、瀏覽器和其他軟體中的漏洞是網路犯罪可以進行攻擊的主要方式之一,在2020年發現了超過 18,100 個,而這相當於每天有50多個新的軟體漏洞,而您只要一個動作打開自動更新功能並在出現提示時點擊更新,就可以如常您的生活及工作。

2.不安全的密碼
對多個帳戶使用相同的密碼和易於猜測的憑證,為駭客提供了極大的便利,他們擁有破解弱加密的軟體,利用殭屍網路(botnet)以自動化方式不斷使用偷來的登入憑證試圖登入網路服務,稱為憑據填充(Credential Stuffing)。您可以使用密碼管理器來記住具強度的密碼並在提供它的任何帳戶上使用雙因素身份驗證 (2FA)。

3.使用公共 Wi-Fi
駭客可以利用相同的網路了解您的互聯網使用情況、登錄您的帳戶並竊取您的身份。為了安全起見,請盡量避開這些公共熱點,若您使用時,也避免在連接時登錄任何重要帳戶。

4.隨意點擊來路不明之連結
網路釣魚是目前最大的網路威脅之一,阻止這些攻擊的首要規則是在點擊之前三思而後行,與發送電子郵件的個人或公司仔細核對以確保其合法,不要被迫採取過於倉促的行為。

5.未在所有設備上使用資安產品
在網路威脅多變的時代,應該確認所有的電腦設備都有安裝專業且具知名度的資安產品,另外也請確認您的行動式裝置(如平板…)是否也有這麼做?

6.點擊不安全的網站
http:// 是網頁伺服器與您的電腦瀏覽器,以一般(非安全)模式在進行互動交談,所以內容有可能遭攔截竊聽;換句話說,在此類網頁上填寫傳送的資料有可能被有心人士看到。而https:// 多了一個字母S的差別代表”安全(secure)”,基本上意謂著,您的電腦與伺服器間的資料傳遞是以加密的方式進行進行互動交談。

7.工作的電子郵件被用於個人的日常
試想使用工作的電子郵件和密碼在消費性購物網站和其他網站上註冊,如果這些網站遭到破壞怎麼辦?駭客就有可能能夠劫持您的公司帳戶,另外使用未受保護的個人電腦設備進行工作其實也會增加額外的風險。

8.通過電話提供詳細訊息
語音網路釣魚(也稱為 vishing)是一種越來越流行的從受害者那裡獲取個人和財務資訊的方式,詐騙者經常偽裝他們的真實號碼以增加攻擊的合法性,所以請盡量避免透過電話發送任何敏感或重要訊息。

9.沒有定期備份
勒索軟體每年給企業造成數億美元的損失,試想如果突然無法開啟您的電腦,裡頭所有的資料,都可能永遠丟失,其中包括家庭照片和重要的工作文件等等;根據 3-2-1 最佳備份原則,定期備份可在最壞的情況發生時,讓您高枕無憂。

10.智能設備沒有被保護
近三分之一的歐洲家庭配備了智能設備,如語音助理、智能電視和監視器;但它們也同時連結網路,也因此成為犯罪分子的目標,進而被劫持並變成殭屍網路,對其他人發起攻擊,或者變成通往您其他設備和資料的管道。
