"DHS empowers its programs to succeed by integrating privacy protections from the outset. The DHS Privacy Office is the first statutorily mandated privacy office in the federal government and serves a unique role as both an advisor and oversight body for the department. DHS views privacy as more than just compliance with privacy laws. Privacy at DHS is also about public trust and confidence. It's about how the government acts responsibly and transparently in the way it collects, maintains, and uses personally identifiable information. DHS employs a layered approach to privacy oversight for the department's cybersecurity activities. It starts with the Chief Privacy Officer and extends through NPPD's [National Protection and Programs Directorate] Component Privacy Officer, the Director of Privacy Technology, and dedicated privacy staff across the department."
