Senior Security Lead



  full-time   employee

District of Columbia
United States

CSRA is seeking a Senior Security Lead.

Help support the Government Accountability Office in its mission to save all US taxpayers money.  Our customer is passionate about their mission and we are tasked with keeping their IT services running smoothly, to help them achieve their goals. The auditors in this 4000 user community are subject area experts in all facets of government and industry best practices. We take great pride in supporting their wide scope of technology needs.

Responsibilities: Manages resources to include personnel, shift scheduling and technology strategy to meet Service area Metrics; communicates with management; serves as organizational point person for business-critical incidents; provides overall direction for the SOC and input to the overall security strategy.

The SOC typically will leverage internal and external resources in response to and recovery from the incident. It is important to recognize that a SOC may not always deploy countermeasures at the first sign of an intrusion. There are three reasons for this:

?           1. The SOC wants to be sure that it is not blocking benign activity.

?           2. A response action could impact a constituency?s mission services more than the incident itself.

?           3. Understanding the extent and severity of the intrusion by watching the adversary is sometimes more effective than performing static forensic analysis on compromised systems, once the adversary is no longer present.

To determine the nature of the attack, the SOC often must perform advanced forensic analysis on artifacts such as hard drive images or full-session packet capture (PCAP), or malware reverse engineering on malware samples collected in support of an incident. Sometimes, forensic evidence must be collected and analyzed in a legally sound manner. In such cases, the SOC must observe greater rigor and repeatability in its procedures than would otherwise be necessary.
