The ability of web services to facilitate platform and language-independent communication between applications has proved to be a boon for organizations, which provide a range of major and minor services, such as customer service management or quoting the price of a stock.
Unfortunately, like the other components of an information infrastructure, web services too are prone to various types of attacks such as denial of service (DoS), SQL injection, spoofing and, XML. In the absence of a single solution to defend against the various threats...
The ability of web services to facilitate platform and language-independent communication between applications has proved to be a boon for organizations, which provide a range of major and minor services, such as customer service management or quoting the price of a stock.
Unfortunately, like the other components of an information infrastructure, web services too are prone to various types of attacks such as denial of service (DoS), SQL injection, spoofing and, XML. In the absence of a single solution to defend against the various threats, a countermeasure strategy that covers all aspects of web services security is necessary to effectively and comprehensively safeguard your information security framework.
Excedor integrates different security elements to create customized Web Services Security solutions that cater to an organization’s specific requirements.
Some of the measures we take to reinforce the security of your web services are:
• We ensure transport confidentiality for to and fro communication with the server to prevent man-in-the-middle (MITM) attacks and eavesdropping.
• We facilitate server authentication by using TLS to authenticate the service provider’s security certificate.
• When performing user authentication, we use TLS to conduct client certificate authentication, which is a stronger form of authentication as compared to basic authentication.
• We apply transport encoding to enforce identical SOAP encoding styles between clients and servers.
• We provide message integrity for data at rest by employ XML digital signatures—for XML data—to ascertain the sender’s identity.
• To prevent brute force cracking and enhance message confidentiality for messages that contain sensitive information both during transfer and at rest, we utilize strong encryption ciphers with sufficient key lengths.
• We validate web service clients’ authorizations and privileges to perform the required actions on the data requested. We also ensure that only web service administrators can access the administration and management functions of a web service application.
• We use schema validation to enforce schema-defined constraints and content validation to validate XML inputs before they are consumed.
• We encode output to prevent cross site scripting (XSS) attacks.
• We install and update virus scanning technologies to prevent hackers from attaching malware and viruses to SOAP messages.
• We limit SOAP messages sizes to prevent DoS attacks.
• We optimize configurations to maximize message throughput to prevent DoS situations.
• We provide XML DoS protection by creating suitable test cases to ascertain whether your XML parser/schema validator can resist DoS attacks.
