Flash Wrapper for ServePDF - Essay Example

Flash wrapper for ServePDF Flash wrapper for ServePDF Introduction Flash wrapper for ServePDF is online software mostly used commercially with offering services in the production of Adobe PDF documents received from the client’s data software. The software hosts the implications of the host client by using a number of technologies like Sun Java and Adobe Flex. The server used in Flash wrapper for ServePDF is often made to be open-source in any given time. In this situation, it serves to generate Adobe PDF documents form the data the client will provide (Perriorellis, 2008). The software is a java iText library porting, as well as a PDF library that is complete for action script allowing for the reading and creation of PDF documents received from any swf files that are running. The software is flexible as it supports most of the PDF features including vertical text, multi-column text, phrases, text manipulation chunks, slide show, images, Unicode and barcodes (Perriorellis, 2008). The above applications indicate that Flash wrapper for ServePDF is an important tool in computing system. Despite its important, the program experiences a number of security issues. Security has for along time been a major concern in computing. Considering the recent trends in computing distribution, its applications and the emergence of World Wide Web, security issues have become crucial to all computer users. The common security issues witnessed while using Flash wrapper for ServePDF are observed in its communication paths, captures of Wireshark, during the installation of the program, its cached in Cache/Squid Proxy and while acquiring data using Java SDK and Adobe (Perriorellis, 2008). Flash Wrapper For Servepdf Security Issues In this program, its communication network is in such away that its communication paths and patterns are of a high level and are normally uncovered hence allowing zeroing on suspicious activities like internal collusion, questionable connections involving both out and in bound, policy violation, and bandwidth overuse. The process of redirecting the Flash wrapper needs significant interaction taking place between the server components and user device (Perriorellis, 2008). This implies that such a feature is only applicable in areas where security separation between the user server and device is required. In addition, considering the protocol dissectors, a huge number is needed during the capturing of traffic causing serous risks as there is a possibility of a bug being found in the dissector. In the previous versions of Flash players that were normally installed on the device of the user or in some cases where the Flash Player is in no position to be installed on the device of the user. In such a situation, Flash content has to be rendered on the servePDF (Perriorellis, 2008). Flash redirection is normally applied so as to have the processing of moving the content of the Adope Flash from the web on the server to the users contents. This process of having the device moved enables the flash direction to reduce both the network and server load thus a better scalability while maintaining a definition user experience that is high. Squid Proxy is common in different platforms that are applicable in Flash Wrapper For ServePDF. This implies that it stores Internet objects that have been requited like FTP server or Web data on any machine that will be closer to the workstation that is requesting for data than the ServePDF. This may result in the setting up of multiple hierarchies in order to make sure that the response time is optimal and the bandwidth usage is low even in cases where the modes happen to be transparent to every user. The above situation can also result in objects duplication in different caches within the network. The lack of free space in the hard disk results in the frequent replacement of the cache. Caches are also easily damaged when exposed to terminating squid. This calls for the need to delete the cache to allow for the restarting of the Squid (Perriorellis, 2008). Wireshark packet captures in this program have proved to be invaluable tools in the administration, troubleshhoting and diagnosis of problems. Such captures can be easily used by intruders to gain access to unauthorized information thus causing security issues in the program. There is a high risk associated with incorrect registry editing of the flash wrapper as it may lead to serious problems calling for the reinstallation of the operating system (Perriorellis, 2008). This makes it very hard to serve PDFS directly to the browser following the associated security reasons. In some cases, even Citrix cannot serve as an assurance that Registry Editor incorrect use can be easily solved. During the collection and receiving data using this program using Java SDK and Adobe, the distribution index allows for no backups in the storage area networks in case of operations that are fault-tolerant. This poses a big security risk as some of the errors will manage to pass undetected before the program begins to run. Data collection using Java SDK take longer as the process of interpreting the device source code has to take place before the application begins. The installer for Data Services develops a directory structure on the serve containing the required resources to build any desired application. The installation also creates a web application which is vulnerable to external application from the developed environment. The installer provides options of installing the integrated serve PDF so as to host such web applications. The WEB-INF/classes and WEB-INF/flex contain the configuration files and java classes and Services configuration files respectively which may contain errors and virus that can be passed to the server. Security Issues Remedies The Silent Runner Sentinel can be used in the program so as to gain visibility to enable the user to be in a position to clearly and easily determine the level, scale and scope of security breaches related to communication paths and networks. This inclusion goes further to actively identify and deal with any possible security configurations. Silent Runner Sentinel is also in a position to play back activities and events from several communications so as to ensure that the threat is validated and have the root cause analysis conducted (Gross, 2006). This implies that this application enhances the response capabilities and incident detection hence placing the user in a position to detect errors in such away that normal tools cannot. User devices have to be configured in order to make use of the feature of the Flash direction only with servers that are trusted. The Flash Redirection requires the installation of Flash Player to be on the user device. Flash Redirection has to be enabled on condition that the Flash is fully secured. ICP protocols are normally applied in this program so as avoid objects duplication in different caches. Some of protocols commonly used include HTCP (hypertext cache protocol) and CARP (Cache array routing protocol) (Perriorellis, 2008).A situation where more objects in the network are maintained, there will be higher the chances of achieving the desired one. Cache objects can be replaced as a result of missing free hard disk by the use of algorithms. In this case, the proxy expunges the data that were not requested for a long period of time. During the use of Registry Editor, the registry is normally backed up before it is edited (Gross, 2006). The data typing strength to the ServePDF either strongly or loosely typed as well as the validation and binding data methods have had significant implications to the interoperability and security applications. Each of the above play roles that are important in the constraining and securing the handling of the information the data received from the client by the servPDF. Poor styles used in implementation and as well as bad practices can lead to serious security implications (Perriorellis, 2008). This calls for the program to be configured and coded in such away that it can be able to deal with these security implications. This can only be achieved if the choices and styles implementations are considered carefully and applied in the correct order and situation. The selection of validation and binding styles also determine the data parsing reliability that plays a crucial role in the parsing of complex security implications and constructs (Perriorellis, 2008). The program also takes into consideration contract compliance of data between the server and the client as well as its robustness and interoperability. Reference Perriorellis, P. (2008).
