Qualifications

• 8+ years as in Security Engineering, Security Analysis, and/or DevSecOps/System Administration
• Bachelor degree in Information Systems, Computer Science, Engineering, or Cyber Security.
• Familiarity with the OWASP Top 10 and other security concerns for web applications
• Understanding of OWASP Application Security Verification Standards (ASVS)
• Understanding of security concepts such as software vulnerabilities, encryption, logging, firewall, SSL, TLS, key vault, security group, container registry, stateful firewall, WAF, NAT, access-list, perimeter security, identity, and access management Skilled in understanding vulnerabilities, assessment of the risk, and the impact on the software, image, VM, Kubernetes clusters, and cloud platforms
• Web Application Security: Knowledge of web application security concepts, common vulnerabilities (e.g., OWASP Top 10), and techniques for testing web applications, including manual testing and using automated scanners like Burp Suite or OWASP ZAP
• Understanding of Vulnerability Concepts:
  • Definition of Vulnerability: A vulnerability is a weakness or flaw in a system, network, application, or process that could be exploited by threat actors to compromise the confidentiality, integrity, or availability of data or resources
  • Vulnerability Classification: Vulnerabilities can manifest in various forms, including software bugs, misconfigurations, design flaws, human errors, and inadequate security controls. Common types of vulnerabilities include buffer overflows, SQL injection, cross-site scripting (XSS), authentication bypass, and insecure direct object references
  • Common Vulnerability Scoring System (CVSS): CVSS is a standardized framework for assessing the severity and impact of vulnerabilities. It provides a numerical score based on factors such as exploitability, impact, and remediation level to help prioritize and manage vulnerabilities effectively.
  • Zero-Day Vulnerabilities: Zero-day vulnerabilities are vulnerabilities that actively exploit applications by threat actors before a patch or mitigation is available from the vendor. These vulnerabilities pose a significant risk because organizations have no advance notice or protection against them.
  • Business Impact: Evaluating the potential consequences of disruptions to critical business operations, helping organizations understand the financial, operational, and reputational impacts of such events.
  • Exploitability: Evaluating the feasibility and potential impact of exploiting vulnerabilities within systems or applications, aiding in determining the level of risk posed by these vulnerabilities and guiding prioritization of mitigation efforts
• Operating System Knowledge: In-depth understanding of various operating systems (e.g., Windows, Linux, Unix) and vulnerabilities.
• Networking Knowledge: Familiarity with networking protocols, services, and infrastructure components (e.g., TCP/IP, DNS, DHCP, firewalls, routers) to understand potential vulnerabilities in networked environments.
• Understanding of virtualization, containerization, and Infrastructure as Code (IaC) concepts Skilled in various cloud platforms. E.g. Microsoft Azure
• Experience with programming languages like Linux Shell, Python for data manipulation and analysis
• Working knowledge of Excel and/or PowerBI data visualization, Statistical prediction, and data aggregation for dashboards and security management insights
• Understanding of Docker, OpenStack, and Kubernetes Experienced Continuous Integration/Continuous Deployment (CI/CD) Familiarity with Azure and ADO concepts Administrator level expertise in Linux.
• Experienced in Ansible and Python scripting Experienced in YAML and JSON file types and their usage Basic familiarity of GO language and GIT.
