Security Delivery Lead

Key Responsibilities

• Security Assurance Regime

• Establish and own the security assurance schedule — ensuring assurance activities are planned, executed, evidenced, and reported on a recurring basis.
• Define and maintain the security assurance evidence framework — specifying what evidence is required, how it is collected, where it is stored, and how it is presented to accreditation authorities and client security teams.

• Security Policy & Procedure Development
• Develop, maintain, and enforce security policies and procedures that ensure the Contractor's compliance.
• Conduct regular policy reviews to ensure currency with evolving client requirements, regulatory changes, and threat landscape developments.
• Manage policy exceptions and deviations through a formal process — ensuring exceptions are risk-assessed, time-bound, approved, and tracked.
• Security Risk Governance
• Establish and maintain the security risk governance framework for the service — defining how security risks are identified, assessed, recorded, escalated, treated, and reported.

• Compliance Management & Audit Support

• Develop and maintain a compliance monitoring framework — defining what is monitored, how compliance is measured, and how non-compliance is addressed.

• Recruitment fraud is a scheme in which fictitious job opportunities are offered to job seekers typically through online services, such as false websites, or through unsolicited emails claiming to be from the company. These emails may request recipients to provide personal information or to make payments as part of their illegitimate recruiting process. DXC does not make offers of employment via social media networks and DXC never asks for any money or payments from applicants at any point in the recruitment process, nor ask a job seeker to purchase IT or other equipment on our behalf.
