Effectiveness of ICAO Security Preventive Measures and Related Effects: A Case of Juba International Airport, South Sudan

This study examines the effectiveness of ICAO security preventive measures adopted by countries and assesses their effectiveness in mitigating security risks in the case of Juba International Airport, South Sudan. This study focuses on the implementation of ICAO security standards and recommended practices (SARPs) at the Juba International Airport (JIA), encompassing comprehensive measures for passenger screening, luggage checks, secure identification of passengers and crew, and restricted area access control to ensure a high level of security. These protocols, including procedures for handling suspicious items or individuals and restrictions on access to restricted zones, aim to prevent security breaches and are supported by regular staff training and effective surveillance systems. The overall effectiveness of security measures at JIA, including access control, screening, monitoring, and emergency response planning, demonstrates a robust defense against potential threats, although concerns about emerging risks, such as cyberattacks, persist. Collaboration and information sharing among security agencies enhance preparedness; however, ongoing vigilance remains essential to effectively address existing and potential security threats. The target population consisted of 132 security officers in various categories at the JIA, with a sample size of 100 selected for the study. This study used a mixed-methods approach that combined qualitative and quantitative data collection and analysis techniques. A survey questionnaire was administered to security officers to gather information on the adoption and effectiveness of ICAO security measures. In-depth interviews were conducted with the airport management and personnel to obtain detailed information on the implementation processes. Secondary data analyses of airport security incidents were performed using the Statistical Package for the Social Sciences (SPSS). The findings reveal a positive perception among security personnel regarding the effectiveness of the measures: approximately 74% affirmed that passenger and luggage screening was conducted, 72% supported secure identification systems, and 69% endorsed effective access control measures. Furthermore, 74% acknowledged the established screening procedures, 70% confirmed protocols for handling suspicious items, and 66% recognized ongoing security training programs. The perceived effectiveness of key security components was high, with 57% rating access control and identification procedures as “very effective,” 54% for screening and inspections, 60% for surveillance and monitoring, and 61% for emergency response planning. Additionally, 64% of respondents considered information-sharing and collaboration efforts to be “very effective.” Despite these positive assessments, concerns about emerging threats persist: 69% of respondents are “very concerned” about terrorism, and an even higher 73% express “very concerned” regarding cyber-attacks. Overall, the results suggest that ICAO security measures at JIA are largely effective in preventing breaches. However, the ongoing threat landscape necessitates continuous vigilance, collaboration, and adaptation to emerging risks to sustain and enhance security resilience.
