system: You are a contract-analysis assistant performing a span-extraction task. You are given an excerpt from a commercial contract and the name of a clause type to locate within it.

Return the exact text of the requested clause, copied verbatim from the excerpt — identical wording and punctuation, with no paraphrasing, summarising, explanation, or added commentary.

The excerpt is one window of a much longer contract and often will not contain the requested clause. If the requested clause does not appear in this excerpt, respond with exactly: Not found.

Output only the extracted clause text, or the exact string `Not found.` — nothing else.

IBM will use commercially reasonable efforts, in cooperation with Customer, to minimize any interruption to Services in the event of such relocation. Security Obligations IBM will: implement firewall settings and other security parameters as defined by Customer and accepted by IBM; administer firewalls specified in Attachment B; perform nightly memory and file system anti-virus scanning and install virus signature definition file updates, as available, for Base Components and Customer Components with Windows operating systems; perform regular scanning of commonly used TCP and UDP ports, on Base and/or Customer Components to attempt to detect ports and services that may be vulnerable to intrusion. IBM will Page 22 of 36 Source: QUANTUM GROUP INC /FL, 8-K, 1/20/2009 use reasonable efforts to inform Customer of intrusion vulnerabilities detected, and schedule and apply changes to security settings agreed to by Customer to attempt to mitigate vulnerabilities. IBM makes no representation or warranty that IBM's monitoring or analysis procedures will identify all intrusions Customer may encounter; perform monthly security parameter status checking and identify when security checking finds parameter status to be different from what was originally established; and authorize root access, administrator access or their equivalents for Base Components to IBM-designated personnel only. Customer must comply and ensure any Customer Subcontractors comply with the following security obligations. Customer will: authorize IBM to perform the Services described above in item a. of Security Obligations; provide firewall setting requirements (ports, filters, and traffic direction) to IBM and provide the number of nodes required for IBM to perform firewall administration; provide IBM with security parameters and settings. Security parameters and settings will be used for monthly security status checking and are subject to IBM's review and acceptance; not access or attempt to access IBM's secure internal network or the resources or information of other IBM customers; when performing any technical security integrity review, penetration test, or vulnerability scan of Base Components or Customer Components: (a) only test, scan or review the IP addresses supplied by IBM to Customer that are part of the Services; (b) only test, scan, or review Customer dedicated Base Components and Customer Components; (c) provide IBM at least one week's prior written notice of the date and time of the review; (d) provide the source IP address information and reviewer contact information to IBM; (e) not perform such reviews more than once per calendar quarter; and not perform or simulate denial-of-service attacks; not administer or create privileged User IDs (User IDs having system or security administrative authority) at the base operating system level or on subsystems managed by IBM; and not disclose any information arising out of IBM or Customer scanning of Base Components or Customer Components to any other entity without IBM's prior written consent. IBM strongly recommends that Customer and any Customer Subcontractors comply with the security guidelines listed below, but Customer may deviate from such guidelines after prior written notice to IBM. IBM will have no liability for any damages arising out of Customer's or Customer's Subcontractors' deviation from any or all of the following guidelines: not use Base Components or Customer Components as a relay to provide Internet access at Customer locations; initiate connections from Base Components or Customer Components to Customer Premises Equipment using either caller ID or Challenge Handshake Authentication Protocol (CHAP); only initiate traffic flows from more secure to less secure networks (i.e., from the Customer secure network to the e-business hosting environment ); access Servers in the e-business Hosting Environment from Customer's premises by establishing a one way trust relationship with password when using Windows; not initiate NFS traffic through the Internet access firewall; only use NFS within a single layer, meaning NFS traffic will not cross firewalls and the Servers will be in the same VLAN; not place NFS export files in the same file structure used for system files and executable files in Customer Components; when creating CGI programs, such programs will: (a) validate input to construct a command line. The input character string will have to be validated to ensure that it does not trigger an undesirable system response including the ability to change
