Improving Webserver Security for Local Tax Reporting Applications Using Standard Penetration Testing Execution Methods

Regional Tax Reporting Application Webserver is one of the public services for taxpayers to report their sales transactions. This application can be accessed on the domain http://sptpd.payakumbuhkota.go.id. This application is public, so the principles of information security must be applied to prevent cyber attacks. The principles of information security include confidentiality, integrity, and availability. To apply this information security principle, it is necessary to conduct vulnerability assesment of the application webserver. This study aims to improve the security of the application webserver so that the data and information in it is secure. The method used in this study is the Penetration Testing Execution Standard which is one of the methods developed by the Pentest Organization to become a standard in analyzing or auditing security systems. The results of vulnerability testing using software Acunetix, Nikto, BurpSuite and Owasp, there are seven types of vulnerabilities, namely: X-Frame Header Options is Missing, CSRF Attack, Cookie Without Only Flash, DNS Vulnerability, Ddos Attack, Bruteforce Page Login and Open Port. The vulnerability can be exploited, where the level of application vulnerability is in the medium category. The recommendations for fixing vulnerabilities can be applied by the developer, so that after repairs are made, the vulnerability level of the application webserver is in the low category and there is only one type of vulnerability, namely BruteForce Page

Relationship between Shear Wave Velocity and SPT-N Value for Residual Soils

The shear wave velocity (Vs) is an important dynamic parameter in the field of geotechnical engineering. One of the surface wave methods is Spectral Analysis of Surface Wave (SASW) has received attention in obtaining the shear wave velocity (Vs) profile by analysing the dispersion curve. SASW is a non-destructive test, fast and time-effective for field survey. Thus, this paper proposed the application of SASW method to obtain the shear wave velocity (Vs) to represent the soil profile. This paper aims to determine the shear wave velocity (Vs) profile using SASW method, where the testing has been conducted at three site of residual soils located in Damansara, Kuala Lumpur and Nilai area. In this study, it shows that the soil profile obtained from shear wave velocity value is similar pattern with profile that obtained using Standard Penetration Testing (SPT), which conventional used in field. The shear wave velocity are proportionally increase with depth.

Probabilistic framework for assessing liquefaction hazard at a given site in a specified exposure time using standard penetration testing

This paper presents a probabilistic framework for assessing the liquefaction hazard at a given site in a given exposure time. Ten sites from different seismic-prone regions of the USA are studied to validate the developed probabilistic framework. Additionally, this framework is extended from the focus of liquefaction potential at a given soil element (or finite layer) to the concern of the whole soil column based on the concept of liquefaction potential index (LPI) proposed by Iwasaki and his co-workers. In this extended framework, the probability of surface manifestation of liquefaction at a given site subjected to all ground motions at all hazard levels in a given exposure time is determined. As an example to illustrate this probabilistic framework, the widely used, standard penetration test (SPT)-based method by Youd et al. is adopted as a building block in the framework. This framework is illustrated with examples and its versatility is demonstrated. Finally, the procedure for extending the developed framework to the evaluation of ground settlement is outlined.

LIQUEFACTION ANALYSIS: CPT VERSUS SPT RESULTS AT JFK AIRPORT

The design and construction of the new JetBlue 26-gate Terminal Facility at JFK Airport in New York City, USA was a complex and interesting endeavor for the Geotechnical Engineers at DMJM Harris. Once operational, the 635,000 sq. ft. facility will operate up to 250 daily flights; an estimated 20 million passengers a year. The new Jet Blue Terminal 5 incorporates the historical TWA Terminal, designed by Eero Saarinen in 1962. The main portion of this structure is being refurbished and incorporated into the new terminal. There were many challenging features to the design of this Project; including marrying the existing historical structure to the new terminal, preventing cross contamination in the aquifers below the site and achieving a design which will perform under seismic conditions. The challenge of the evaluation of the soil under seismic conditions is discussed herein. Liquefaction under seismic conditions at JFK Airport can be a key factor to foundation design and selection. Our investigation of the site incorporated the use of both Standard Penetration Testing (SPT) and Cone Penetration Testing (CPT) to closely identify the areas subject to liquefaction risk. A correlation between the results of both the analyses was established. This enabled us to determine the thickness of liquefiable zone and develop a cost effective design solution that will perform successfully should a seismic hazard occur in the future. The methodology utilized and the correlation observed will be presented in the paper.
