• Each Device must be uniquely associated with a specific, individual user;
• Devices must be configured for automatic patching. All operating system and application security patches must be installed within the timeframe recommended or required by the issuer of the patch;
• Devices must be encrypted (i.e., full disk, endpoint encryption) and secured with a protected (e.g., password, PIN, finger print, facial recognition, biometrics, etc.) screen lock with the automatic activation feature. Users must lock the screen or log off when the device is unattended;
• Devices must not be rooted or jailbroken;
• Devices must be periodically scanned for restricted/prohibited software (e.g., certain peer-to-peer sharing apps that have been found to exploit/exfiltrate data); and
• Devices must run an acceptable industry standard anti-malware solution. On-access scan and automatic update functionality must be enabled.
  
  

4.3.3 Supplier shall implement policies designed to prevent the storage of ExtraHop Confidential Information on unencrypted smartphones, tablets, USB drives, DVD/CDs, or other portable media without prior written authorization from ExtraHop; and take measures to prevent accidental exposure of ExtraHop Confidential Information (e.g., using privacy filters on laptops).

6.5 Upon request, with reasonable advance notice and conducted in such a manner not to unduly interfere with Supplier’s operations, ExtraHop reserves the right to conduct, or to engage third parties to conduct, an audit of Supplier’s compliance with the requirements in this Security Addendum relating to ExtraHop Confidential Information including but not limited to: (a) a review of Supplier’s applicable policies, processes, and procedures, (b) a review of the results of Supplier’s most recent vulnerability assessment (e.g., application vulnerability scanning, penetration testing, and similar testing results) and accompanying remediation plans, and (c) on-site assessments of Supplier’s physical security arrangements and Supplier IT Systems during Supplier’s regular working hours pursuant to a mutually agreeable audit plan. ExtraHop reserves the right to conduct an onsite audit of Supplier on ten (10) business days prior written notice during regular business hours. This right shall survive termination or expiration of the Agreement so long as Supplier Processes ExtraHop Confidential Information provided under the Agreement. Supplier agrees to cooperate fully with ExtraHop or its designee during such audits and shall provide access to facilities, appropriate resources and applicable supporting documentation to ExtraHop.

6.6 If ExtraHop has a reasonable basis to believe that Supplier has breached or is likely to breach the terms of this Security Addendum, then, in addition to any other applicable rights, ExtraHop may, upon five (5) days’ notice, perform a vulnerability assessment. At reasonable request from ExtraHop, Supplier will promptly cooperate with ExtraHop to develop a plan to protect ExtraHop Confidential Information from any applicable failures or attacks, which plan will include prioritization of recovery efforts, identification of and implementation plans for alternative data centers or other storage sites and backup capabilities.
