Why Easy To Use Software Is Putting You At Risk



Why Easy to​ Use Software is​ Putting you​ At Risk
Can Easy to​ Use Software Also Be Secure
----------------------------
Anyone who has been working with computers for a​ long time will have noticed that mainstream operating systems and applications have become easier to​ use over the​ years (supposedly) .​
Tasks that use to​ be complex procedures and required experienced professional to​ do can now be done at​ the​ push of​ a​ button .​
For instance,​ setting up an​ Active Directory domain in​ Windows 2000 or​ higher can now be done by a​ wizard leading even the​ most novice technical person to​ believe they can securely setup the​ operating environment .​
This is​ actually quite far from the​ truth .​
Half the​ time this procedure fails because DNS does not configure properly or​ security permissions are relaxed because the​ end user cannot perform a​ specific function .​
If It's Easy to​ Develop,​ is​ It Also Secure
--------------------------------------------------
One of​ the​ reasons why operating systems and applications appear to​ be easier to​ work with then they use to​ is​ developers have created procedures and reusable objects to​ take care of​ all the​ complex tasks for you​ .​
For instance,​ back in​ the​ old days when I​ started as​ a​ developer using assembly language and c/c++,​ I​ had to​ write pretty much all the​ code myself .​
Now everything is​ visually driven,​ with millions of​ lines of​ code already written for you​ .​
All you​ have to​ do is​ create the​ framework for your application and the​ development environment and compiler adds all the​ other complex stuff for you​ .​
Who wrote this other code? How can you​ be sure it​ is​ secure .​
Basically,​ you​ have no idea and there is​ no easy way to​ answer this question .​

Secure Environments Don't Exist Well With Complexity
----------------------------
The reality is​ it​ may look easier on​ the​ surface but the​ complexity of​ the​ backend software can be incredible .​
And guess what,​ secure environments do not coexist well with complexity .​
This is​ one of​ the​ reasons there are so many opportunities for hackers,​ viruses,​ and malware to​ attack your computers .​
How many bugs are in​ the​ Microsoft Operating System? I​ can almost guarantee that no one really knows for sure,​ not even Microsoft developers .​
However,​ I​ can tell you​ that there are thousands,​ if​ not hundreds of​ thousands of​ bugs,​ holes,​ and security weaknesses in​ mainstream systems and applications just waiting to​ be uncovered and maliciously exploited.
How Reliable and Secure are Complex Systems?
----------------------------------------------------------
Let's draw a​ comparison between the​ world of​ software and security with that of​ the​ space program .​
Scientists at​ NASA have know for years that the​ space shuttle is​ one of​ the​ most complex systems in​ the​ world .​
With miles of​ wiring,​ incredible mechanical functions,​ millions of​ lines of​ operating system and application code,​ and failsafe systems to​ protect failsafe systems,​ and even more failsafe systems to​ protect other systems .​
Systems like the​ space shuttle need to​ perform consistently,​ cost effectively,​ and have high Mean-Time-Between-Failure(MTBF) .​
All in​ all the​ space shuttle has a​ good record .​
One thing it​ is​ not though is​ cost effective and consistent .​
Every time there is​ a​ launch different issues crop up that cause delays .​
In a​ few circumstances,​ even the​ most basic components of​ this complex system,​ like O rings,​ have sadly resulted in​ a​ fatal outcome .​
Why are things like this missed? Are they just not on​ the​ radar screen because all the​ other complexities of​ the​ system demand so much attention? There are million different variables I'm sure .​
The fact is,​ NASA scientists know they need to​ work on​ developing less complex systems to​ achieve their objectives .​
This same principal of​ reducing complexity to​ increase security,​ performance,​ and decrease failures really does apply to​ the​ world of​ computers and networking .​
Ever time I​ here associates of​ mine talk about incredibly complex systems they design for clients and how hard they were to​ implement I​ cringe .​
How in​ the​ world are people suppose to​ cost effectively and reliably manage such things .​
In some cases it's almost impossible .​
Just ask any organization how many versions or​ different brands of​ intrusion detection systems they have been through .​
As them how many times the​ have had infections by virus and malware because of​ poorly developed software or​ applications .​
Or,​ if​ they have ever had a​ breach in​ security because the​ developer of​ a​ specific system was driven by ease of​ use and inadvertently put in​ place a​ piece of​ helpful code that was also helpful to​ a​ hacker.
Can I​ Write a​ Document Without a​ Potential Security Problem Please
-----------------------------------------------
Just a​ few days ago I​ was thinking about something as​ simple as​ Microsoft Word .​
I​ use MS-Word all the​ time,​ every day in​ fact .​
Do you​ know how powerful this application really is? Microsoft Word can do all kinds of​ complex tasks like math,​ algorithms,​ graphing,​ trend analysis,​ crazy font and graphic effects,​ link to​ external data including databases,​ and execute web based functions .​
Do you​ know what I​ use it​ for,​ to​ write documents .​
nothing crazy or​ complex,​ at​ least most of​ the​ time .​
Wouldn't it​ be interesting that when you​ first installed or​ configured Microsoft Word,​ there was an​ option for installing only a​ bare bones version of​ the​ core product .​
I​ mean,​ really stripped down so there was not much to​ it .​
You can do this to​ a​ degree,​ but all the​ shared application components are still there .​
Almost every computer I​ have compromised during security assessments has had MS-Word installed on​ it .​
I​ can't tell you​ how many times I​ have used this applications ability to​ do all kinds of​ complex tasks to​ compromise the​ system and other systems further .​
We'll leave the​ details of​ this for another article though.
Conclusion
----------
Here's the​ bottom line .​
The more complex systems get,​ typically in​ the​ name of​ ease of​ use for end users,​ the​ more opportunity for failure,​ compromise,​ and infection increases .​
There are ways of​ making things easy to​ use,​ perform well,​ and provide a​ wide variety of​ function and still decrease complexity and maintain security .​
It just takes a​ little longer to​ develop and more thought of​ security .​
You might think that a​ large part of​ the​ blame for complex insecure software should fall on​ the​ shoulders of​ the​ developers .​
But the​ reality is​ it​ is​ us,​ the​ end users and consumers that are partially to​ blame .​
We want software that is​ bigger,​ faster,​ can do just about everything,​ and we want it​ fast .​
We don't have time to​ wait for it​ to​ be developed in​ a​ secure manner,​ do we?
