Last week one news item that attracted media attention was the hacking of some nearly 450,000 passwords from Yahoo Service called ‘Yahoo Voice'. The communications on the incident state that, SQL Injection is the primary technique adopted by hackers to get the information out of databases and publish them.
As per further communications, we find the affected company taking more precautions to ensure that security is their highest priority. These events will also generally shake the Cloud Adoption at the enterprise level, where always the Fear, Uncertainty and Doubt in the minds of CIOs may increase due to these incidents.
However the following are the best practices and guidelines that should be adopted by any enterprise when adopting hybrid cloud computing and a one-off incident should not dampen their road map to hybrid computing adoption.
In other words the incident is not really due to the adoption of Cloud or a multi-tenant model rather from not following the age-old best practices. This also indicates the significance of Cloud Brokers or intermediaries who have substantial knowledge of enterprise computing paradigm to play an increasing role in ensuring enterprises adopt cloud computing in a secure manner.
Lessons Learned In Yahoo Password Hacking
1. Not Following Security Fundamentals During Development
Whatever the changes in technology are, the fundamentals of development and coding remains the same. Most times SaaS vendors have high pressure on time-to-market, which may at times make them work around on security fundamentals, which is not correct. If you are accepting input from the user, it needs to be validated always before the input is acted upon. Lack of validation of input is the root cause behind attacks like Cross-Site Scripting or SQL Injection. In a multi tenant world the risk of SQL Injection is increased many a fold, because the hacker could always enter the system as a legitimate user by creating an valid account and then start hacking the data other customers.
I have earlier elaborated about SQL Injection In SaaS in an article in 2010 itself, whose thought process is still valid when it comes to developing SaaS and multi tenant applications.
2. Not Encrypting at the Database Level
Encryption of key data is one of the most important security aspect of any database in general and a multi tenant database in particular. However most times enterprises may take the path of encrypting at the Virtual Machine or Volume level, which means the Entire Disk even if it is physically stolen will not be useful to the hacker.
While this is a very useful feature such level of encryption still not useful, when the hacker legitimately gets access to the virtual machine in which the database is hosted. So additionally database level encryption which further provides encryption at the user level, i.e only users who have got READ permissions on the database can view the data, will provide an added level of security.
In my earlier article on Protecting Data At Rest In Public Clouds, I have compared the options between middle ware vs RDBMS in protecting the data. As evident a combination of both would make the multi-tenant database highly secured.
3. Exposing Too Much Metadata
How many times you have a database table storing credit card information is named as ‘CREDIT_CARD' or the password column in a user database is named as PIN or Password. While the best practices of database design in the past indicated the use of correct column names, and meta data like comments at the database level, they may act detrimental to the sensitive data in a today's world.
It is always advisable to avoid too much meta data from sensitive columns and keep them as part of the supporting documentation. There is no rule which states that a CREDIT CARD information is stored in a table named temp_t1 and let your application map temp_t1 is indeed a table containing credit card information.
4. Not Using Best of Features in the Databases
Today most of the software vendors have the pressure to make their product run against multiple databases . This provides them a much wider marketing capability. While this is important from the business perspective, due to this restriction we have seen the products that are using powerful RDBMS systems as a mere data store and not utilizing their best security features. This will result in reduced security at the database level because none of the security features are really used.
In my earlier article on Implementing Multi Tenancy Using Oracle Virtual Private Database, I have elaborated on how the best features like VPD in Oracle provide lot of security features so that if properly applied, some data is not visible to a user unless the application sets the appropriate context. Similarly these features can mask a certain columns to be not visible when queried directly. Also the features like fine grained auditing provide lot of auditing features against database security breaches.
Also if database level security is properly applied, we could utilize roles, grants and privileges in such a manner that the database connections get only EXECUTE privileges on the stored procedures and no direct READ access to the underlying tables, these kind of design patterns protect the data further.
This points to the fact that the product vendors should concentrate on unique security features of the databases like Oracle, Sql Server and DB2 and implement them in their design apart from the application level security. The need for porting the application to multiple databases should not reduce the security needs of the application.
5. Not Masking the Data
Masking the data is about , taking the data in the current form and convert it into a different format for storage purposes. It is slightly different from the encryption that the data is in readable form but will not make any sense if you don't know the de-masking algorithm. Traditionally masking is only done when the production data is ported to a test or development machine and also when a production data is ported to a offshore development location.
However we have not seen much instances of live production instances using masking techniques to protect the security information.
What is the golden rule that states that a social security number always to be stored as a single column of 9 characters and stored contiguously, what if the same is stored in three different columns with the numbers flipped and the application reverses them and forms into a proper social security number? This is just an example, the same principle can be applied to a credit card or a password or a pin, so that only application knows how to make meaning out of a masked sensitive data and not anyone else.
As indicated in the beginning of the articles, there will be a few instances of security breaches when so much new services are delivered over the public internet in a short time. However enterprises need not worry from them as they are not issues out of the fundamental concept of Cloud or Multi Tenancy itself, but because of the way the they are implemented. Adopting the best of design patterns like DAO access pattern which abstracts the database calls from the application and doing proper validation along with the database level protection techniques explained above, will prevent these incidents in the future.

Thomas Bitman of Gartner wrote a blog post last year about why OpenStack projects fail. In that article, he outlined three particular metrics which together cause 60% of OpenStack projects to fall short of expectations: Wrong people (31% of failures): a successful cloud needs commitment both from the operations team as well as from "anchor" tenants. Wrong processes (19% of failures): a successful cloud automates across silos in the software development lifecycle, not just within silos.

There's a lot of things we do to improve the performance of web and mobile applications. We use caching. We use compression. We offload security (SSL and TLS) to a proxy with greater compute capacity. We apply image optimization and minification to content. We do all that because performance is king. Failure to perform can be, for many businesses, equivalent to an outage with increased abandonment rates and angry customers taking to the Internet to express their extreme displeasure.

Right off the bat, Newman advises that we should "think of microservices as a specific approach for SOA in the same way that XP or Scrum are specific approaches for Agile Software development". These analogies are very interesting because my expectation was that microservices is a pattern. So I might infer that microservices is a set of process techniques as opposed to an architectural approach. Yet in the book, Newman clearly includes some elements of concept model and architecture as well as p...

Monitoring of Docker environments is challenging. Why? Because each container typically runs a single process, has its own environment, utilizes virtual networks, or has various methods of managing storage. Traditional monitoring solutions take metrics from each server and applications they run. These servers and applications running on them are typically very static, with very long uptimes. Docker deployments are different: a set of containers may run many applications, all sharing the resource...
