Job Description

This is an analyst role and candidate must be able to demonstrate ability to perform and support in-depth investigations and ‘hunting’ activities. Demonstrated experience in using the Splunk Enterprise Security SIEM technologies as an analyst is REQUIRED. Holding the Splunk Power User Certification is PREFERRED. Holding Certified Ethic Hacker (CEH) and/or Certified Incident Handler (GCIH or ECIH) credentials is a plus for this position.

This position is ideally based in AUSTIN, TX (the right remote candidate can be considered), and will support the customer’s 24x7 Security Operations Center (SOC). This position is in direct support (on-site at customer facilities) of an AT&T customer in the government sector. AT&T is providing Managed Security Service Provider (MSSP) functions related to the Security Operations Center (SOC) including Tier 1 through Tier 3 resource capabilities and activities related to security monitoring, threat, and vulnerability management and incident response (IR). Preference will be made for candidates who can support ‘non-business hours’ shifts.

Responsibilities
• Characterize and analyze network traffic to identify anomalous activity and potential threats to network resources.
• Document and escalate incidents (including event's history, status, and potential impact for further action) that may cause ongoing and immediate impact to
the environment.
• Perform cyber defense trend analysis and reporting.
• Perform event correlation using information gathered from a variety of sources within the enterprise or MSSP environment to gain situational awareness and
determine the effectiveness of an observed attack.
• Provide daily summary reports of network events and activity relevant to cyber defense practices.
• Receive and analyze network alerts from various sources within the environment and determine possible causes of such alerts.
• Provide timely detection, identification, and alerting of possible attacks/intrusions, anomalous activities, and misuse activities and distinguish these incidents
and events from benign activities.
• Use cyber defense tools for continual monitoring and analysis of system activity to identify malicious activity.
• Analyze identified malicious activity to determine weaknesses exploited, exploitation methods, effects on system and information.
• Determine tactics, techniques, and procedures (TTPs) for intrusion sets.
• Recommend computing environment vulnerability corrections.
• Conduct research, analysis, and correlation across a wide variety of all source data sets (indications and warnings).
• Create and document procedures and work instructions for use by the SOC staff (Tier 2 through Tier 3).
• Train and mentor other analysts as needed.
• Validate events/alerts received from all monitored security systems against network traffic using packet analysis tools.
• Assist in the construction of signatures which can be implemented on cyber defense network tools in response to new or observed threats within the
network environment or enclave.
• Monitor external data sources (e.g., cyber defense vendor sites, Computer Emergency Response Teams, Security Focus) to maintain currency of cyber defense
threat condition and determine which security issues may have an impact on the enterprise.
• Provides cybersecurity recommendations to leadership based on significant threats and vulnerabilities.
