( CNN ) A Transportation Security Administration committee concluded that full screening of airport employees nationwide would not lower the overall risk to the public , according to a report released Monday . The report by the TSA 's Aviation Security Advisory Committee said that full employee screening would not `` appreciably increase the overall system-wide protection .

Full physical screening of employees also `` is incapable of determining a person 's motivations , attitudes and capabilities to cause harm , among other limitations . '' `` No single measure can provide broad-spectrum protection against risks or adversaries , '' the report said . `` Therefore , risk-based , multi-layered security offers the greatest ability to mitigate risks through the application of flexible and unpredictable measures to protect commercial aviation . '' The TSA and most airports could not afford 100 % employee screening , the report said . Only two major airports in the U.S. -- Miami and Orlando -- require employees to be screened through metal detectors , a CNN investigation found earlier this year . As a result of the report , TSA Secretary Jeh Johnson announced immediate actions , including criminal background checks every two years for all airport aviation workers , screening of airline and airport employees traveling as passengers , reduction of access points to secure areas at all airports and increased random screening of aviation employees . Johnson requested the TSA study after a Delta Air Lines ramp worker and passenger at Hartsfield-Jackson Atlanta International Airport were arrested in December for allegedly smuggling guns onto flights to New York . Since the incident , the airport has hired private security to check the bags of employees when they show up for work and has increased overall security . `` Immediately following the incident in December 2014 , TSA increased the random and unpredictable screening of aviation workers at various airport access points to mitigate potential security vulnerabilities , '' Johnson said in a statement . Sen. Charles Schumer called Johnson 's announcement `` a prompt response and a significant first step to closing the gaping loopholes in airport security , especially with regard to reducing access points and enhancing criminal background checks . '' Specifically , the TSA report said employee vetting should be strengthened by `` updating the list of disqualifying criminal offenses , instituting continuous activity monitoring through the inclusion of additional Federal Bureau of Investigation ( FBI ) and DHS data sources , and maintaining a national database of airport employees whose credentials have been revoked for cause . '' In addition , the TSA should expand the collection of domestic intelligence , which would include monitoring social media , and expand national reward programs to encourage employees to report security issues , the report said . `` Although there is no perfect security system , the multiple layers -- which can be routinely enhanced or modified -- provide an effective means to secure passengers , employees and facilities , '' the report said . It also recommended increased surveillance of employees who work inside baggage rooms and cargo areas . CNN revealed this month that passengers filed 30,621 claims from 2010 to 2014 for valuables that were missing from luggage . The TSA report agreed with a 2008 Homeland Security study that found random screening was more cost-effective than mandatory airport employee screening . The committee that conducted the TSA study consisted of representatives from the TSA , airports , airlines , airline pilots , aviation security and law enforcement . Rep. John Katko , R-New York and chairman of the House Homeland Security Subcommittee on Transportation Security , said , `` As threats to aviation security continue to evolve , it is critical that the Transportation Security Administration , as well as the airport community , are adequately prepared to mitigate insider threats . I look forward to having a meaningful dialogue with airport stakeholders and the TSA on what can be done , going forward , to improve employee vetting and screening for those with access to sensitive and sterile parts of airports . '' Rep. Kathleen Rice , D-New York , a ranking member of the Transportation Security Committee , said the report makes it clear that the `` TSA must do more to neutralize the insider threat and prevent security breaches like we saw in December . '' `` Screening every single employee may not be a cure-all solution , but every single employee should come to work every day with reason to expect that they 'll face random screening and inspections , '' she said . Lauren Stover , security director at Miami International Airport , told CNN , `` We support the findings of the committee and agree that there is no single solution in mitigating the insider threat , however we will continue our employee screening program as we believe that physical screening is a critical component to a layered security program .

A new TSA report advises against full screening of airport workers . The agency says it is not recommending that travelers be screened for weapons or explosives at the checkpoint.
