Guest Editor: Today's post is from Taras Kholopkin. Taras is a Solutions Architect at SoftServe, Inc. In this post, Taras will review secure data transmission in the ASP.NET MVC framework.
Secure data transmission is a critical step towards securing our customer information over the web. In fact, many of our SoftServe applications are regulated by HIPAA, which has the following secure data transmission requirements:
- Client-server communication should be performed via secured channel (TLS/HTTPS)
- Client (front-end application) should not pass any PHI data in URL parameters when sending requests to the server
- All data transmission outside of the system should be performed via secure protocol (HTTPS, Direct Protocol, etc.)
To satisfy this requirement, let's examine how to secure data transmission in an ASP.NET MVC application.

As someone who spends half of their year teaching web application security, I tend to give a lot of presentations that include live demonstrations, mitigation techniques, and exploits. When preparing for a quality assurance presentation earlier this year, I decided to show the group a demonstration of Cross-Site Request Forgery (CSRF) and how to fix the vulnerability.
A CSRF Refresher
If you're not familiar with Cross-Site Request Forgery (CSRF), check out the article Steve Kosten wrote earlier this year about the attack, how it works, and how to defend your applications using synchronization tokens:
My favorite way to demonstrate the power of CSRF is by exploiting a vulnerable change ...
Guest Editor: Today's post is from Taras Kholopkin. Taras is a Solutions Architect at SoftServe, Inc. In this post, Taras will take a look at creating an audit logging action filter in the ASP.NET MVC framework.
Audit logging is a critical step for adding security to your applications. Often times, audit logs are used to trace an attacker's steps, provide evidence in legal proceedings, and used to detect and prevent attacks as they are occurring. If you're not convinced yet, many regulatory compliance laws, such as HIPAA, also require security-specific audit logs to be kept. With that said, let's take a look at some high-level things to consider as you build out your audit logging functionality.
Events to Log:
The first step is deciding which events require logging. While regulatory compliance laws, such as HIPAA and PCI, may specify exactly which actions should be logged, each application is different. Here are some general actions to
Guest Editor: Today's post is from David Hazar. David is a security engineer focusing on cloud security architecture, application security, and security training. In this post, David will take a look at the encryption options for applications hosted in the cloud.
Over the last decade, due to new compliance requirements or contractual obligations, many, if not most, companies have been implementing encryption to better protect the sensitive data they are storing and to avoid having to report a breach if an employee loses a laptop or if backup media is lost in the mail. One of the more popular ways of adding this additional protection is to implement some form of volume-based, container-based, or whole-disk encryption. It would be difficult to argue that there is an easier, more cost-effective method to achieve compliance than to utilize this type of encryption. Also, although there are potential weaknesses to some implementations of the technology, it is pretty
Guest Editor: Today's post is from Taras Kholopkin. Taras is a Solutions Architect at SoftServe, Inc. In this post, Taras will take a look at the data validation features built into the ASP.NET MVC framework.
Data validation is one of the most important aspects of web app development. Investing effort into data validation makes your applications more robust and significantly reduces potential loss of data integrity.
Out of the box, the ASP.NET MVC framework provides full support of special components and mechanisms on both the client side and the server side.
