The next evolution of the firewall has to combine dynamic policy-based security with performance, rapid scaling, high availability and application intelligence. Today, increasing attention is paid to network firewall design quality due to regulations such as the Sarbanes-Oxley act, CobiT framework, the Payment-Card Industry Data Security Standard (PCI DSS) and the NIST standard. All these regulations include specific sections dealing with firewall configuration, management and audit. This paper is a humble attempt to examine various types of firewalls operational as on today and cross reference each firewall operation with causes and effects of weaknesses in their operation. In addition, we analyze reported problems with existing firewalls. Detailed analysis and comparison is done in terms of cost, security, operational ease and implementation of Open source packet filter (PF) firewall, Checkpoint SPLAT and Cisco ASA in a testing environment with laboratory generated traffic. Various throughputs and connections statistics were used as benchmark for performance comparison. The results indicated that Cisco ASA outperforms its peers in most performance criterions. Checkpoint SPLAT and OpenBSD PF also provides reasonably good and competitive performance. The results reported in this paper will also be useful in comparing vendors to procure firewall based on one's own organizational business requirements.","PeriodicalId":290448,"journal":{"name":"2011 International Conference on Devices and Communications (ICDeCom)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130514214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, this modulation scheme is seldom used in practice due to the high computational complexity involved in decoding the received signal in the presence of noise. The basic aim of this paper is to reduce this decoding complexity. Here, we propose a low complexity detection algorithm which makes use of maximum likelihood (ML) decoding not over the entire signal constellation but over a proper subset of the constellation that lies on a hypersphere thereby reducing the computational complexity for decoding. Computational complexity has been evaluated for various values of transmitted power and the result has been plotted for both ML detection algorithm and the proposed algorithm at a fixed data rate. The BER performance for both the algorithms has also been compared at a fixed data rate and the result has been plotted. The results show that the proposed algorithm is far superior to ML detection algorithm in terms of computational complexity.","PeriodicalId":290448,"journal":{"name":"2011 International Conference on Devices and Communications (ICDeCom)","volume":"4683 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127787263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
