Appendix 1 – Security Measures supporting the Standard Contractual Clauses

The Recipient Vendor Entity shall apply the following:

Technical:

1. Strong encryption that meets industry best practices, is robust against cryptanalysis, is not susceptible to interference or unauthorized access, and for which key access is limited to specific authorized individuals with a need to access Personal Data in order to engage in Processing or, wherever practicable, such key access is limited solely to the Transferring AT&T Entity;

2. Wherever practicable with respect to Processing, pseudonymization sufficient to cause Personal Data to no longer be attributable to a specific individual, provided safeguards are in place to prevent re-identification and the algorithmic process or key to re-establish identity is held only by the Transferring AT&T Entity;

3. If already the case as at the date of receipt of this SCC Amendment or otherwise practicable, physical locations in which Sensitive Personal Data are Processed will be limited to the applicable Extended EEA Country or countries deemed adequate to receive such Personal Data under the Data Protection Laws of the applicable Extended EEA Country;

4. Restrictions to prevent Processing any Personal Data on devices or systems not protected by the Recipient Vendor Entity’s firewall;

5. Access restrictions to limit Processing to authorized Recipient Vendor Entity workforce and devices authorized explicitly by the Recipient Vendor Entity through proper separation of duties, role-based access, on a need-to-know and least privilege basis;

6. Multi-factor authentication and use of a virtual private network for any remote access to Recipient Vendor Entity systems or Personal Data;

7. Physical security procedures, including the use of monitoring 24 hours /7 days a week, access controls and logs of access, and measures sufficient to prevent physical intrusions to any Recipient Vendor Entity or other Vendor Affiliate’s facility where Personal Data is Processed;

8. Secure disposal of equipment and physical and electronic media that contain Personal Data;

9. Ongoing vulnerability identification, management and remediation of systems including applications, databases, and operating systems used by the Recipient Vendor Entity to Process Personal Data;

10. Logging and monitoring to include security events, all critical assets that Process Personal Data, and system components that perform security functions for the Recipient Vendor Entity or other Vendor Affiliate network (e.g., firewalls, IDS/IPS, authentication servers) intended to identify actual or attempted access by unauthorized individuals and anomalous behavior by authenticated users;

11. Monitoring, detecting, and restricting the flows of Personal Data on a multi-layered basis, including but not limited to the use of network segmentation, secure configuration of firewalls, intrusion detection and/or prevention systems, denial of service protections;

12. Remote work procedures that require “clean desk” standards in place and a remote work management program that limits use to only devices authorized pursuant to Vendor’s security program; and

13. Recipient Vendor Entity shall, at the request of data Transferring AT&T Entity, promptly provide a copy of its most recent Recipient Vendor Entity SOC2 Type II report, PCI Attestation of Compliance and/or industry certification such as ISO/IEC 27001 or any successor standards for information security management. If Recipient Vendor Entity does not hold such certification, it must conduct, at its own expense no less than annually, an independent third-party audit of Recipient Vendor Entity’s security program and systems, and facilities used to Process Personal Data, with a detailed summary of the report to be provided to the Transferring AT&T Entity.
