C.2.3. - Local Security Policy

All contractor employees who require physical access to government-controlled facilities or logical access to government information and or information systems are subject to a fitness determination and appropriate vetting. To assist in the vetting process, the contractor must submit a notice of visit form for each employee who will perform work on the contract, including at the minimum, the name, social security number and date of birth of each employee performing work on the contract that need physical and or logical access.

Documents containing personally identifiable information may only be submitted via encrypted email, by first class mail or it may be hand carried to the security office. Notice of visits must be submitted through the government contracting officer representative (COR) or technical representative who will deliver them to the security office. All notice of visits must be received three business days in advance of the contractor reporting for work.

The contractor will work through the COR or technical representative for the contract who will serve as the liaison between the security office and the contractor. Contractor employees who are not sponsored by a government employee will not be granted access to any facilities under HECSA control nor will HECSA security approve logical access to information systems if a notice of visit containing either the DOD ID number or the social security number is not provided to the security office.

Contractor personnel who do not require a common access card may be granted physical access based on favorable results of an NCIC III records check.

Contractors who need a common access card must have the minimum of a favorably adjudicated NACI. If no investigation is on file, the CAC will not be issued until a favorable FBI fingerprints check is received by the security office and the NACI has been initiated in PSIP. HECSA Security will initiate all NACI investigations. Contractors who require access to classified information must be performing work on a classified contract and the contract company is responsible for initiating all required investigations for the appropriate security clearance.

If an employee has been the subject of a previous favorably adjudicated investigation, it may be reciprocally accepted if there has not been a two-year break in service and there is no presence of new and potentially unfavorable information that casts doubt about the subject’s suitability. When a background check is reciprocally accepted but is more than 5 years old, the security office may initiate an NCIC III check to ensure no new unfavorable information exists.

Contractor employees whose access to classified information has been suspended or revoked will not be authorized logical access to government information systems IAW AR 25-2 paragraph 4-14 b (2) until that investigation is favorably adjudicated. These personnel will also not be allowed unescorted access to government facilities until the investigation has been favorably adjudicated by the Command Security

Manager. OPM Final Credentialing Standards allow agencies to deny a CAC or PIV card to any individual who has had their access to classified information denied or revoked. Further due process is not required in these situations. The contractor must provide employees who can be cleared to perform work and must immediately provide replacement employees for those who cannot be cleared.

The contractor will be provided the organizations critical information (CIL) list and OPSEC plan. The contractor must ensure all employees, including subcontractor employees, are aware of the organization’s critical information list and how to protect that information. All new contractor employees will complete

Level I OPSEC training within 30 calendar days of their reporting for duty. Additionally, all contractor employees must complete annual OPSEC awareness training. OPSEC training can be taken online at the following link http://cdsetrain.dtic.mil/opsec/index.htm Certificates of training must be provided to the
