Network Security and Compliance

GIAC Certification
Information Assurance (IA) is defined by the U.S. DoD as "development, operation, management, and enforcement of security capabilities for systems and networks." Global Information Assurance Certification (GIAC) was established in 1999 to test and certify the knowledge and experience of computer security experts in various fields of information assurance. GIAC certifications are recognized globally by industry, military and government institutions including the United States National Security Agency (NSA). GIAC certifications require candidates to complete rigorous testing to demonstrate their depth of skills in specific knowledge areas, not just general computer security knowledge. Areas covered by GIAC certifications include audit, intrusion detection, incident handling, firewalls and perimeter protection, forensics, hacker techniques, Windows and Unix operating system security, plus secure software and application coding

Incident Handling and Response
Security professionals who have earned the GIAC Certified Incident Handler (GCIH) credential have demonstrated in-depth knowledge of the current threats to systems and networks, along with effective countermeasures. Progent's GIAC-certified security engineers have the knowledge and experience to manage incidents, understand common attack techniques and tools, defend against and respond to attacks when they occur, and detect security gaps in your environment. Additionally, Progent's GIAC-certified information assurance consultants are sensitive to legal issues associated with responding to computer attacks, including employee monitoring, working with law enforcement, and handling evidence.

Progent's incident handling experts can offer consulting assistance both on how to respond to a security incident and how to understand and foil the techniques used by hackers to penetrate your network.

Responding to a Security Incident
Progent's information assurance consultants can help you plan and implement a precise step-by-step procedure for responding to successful network attacks or to physical incidents such as fires, floods and crime. By putting in place a proven and well-defined methodology for incident handling, your company will be able to get systems and services back online as quickly and securely as possible. The step-by-step incident response model recommended and supported by Progent covers these phases:

• In the Preparation Phase, you create a set of tools to use as an incident response Jump Kit, identify the core team of responders, and deploy appropriate instrumentation for your site and system
• In the Identification Phase you report signs of an incident, take the first steps to control it, and establish a chain of custody so that no relevant information or evidence is lost or unreported
• In the Containment Phase you implement predetermined video and audio documentation strategies, execute containment and quarantine procedures, pull the network cable and switch if required, and identify and isolate the Trust Model
• In the Eradication Phase you evaluate whether a backup is compromised, totally rebuild the Operating System if required, and if necessary move to a new architecture
• In the Recovery Phase you determination who makes the decision to return to production, monitor the system, and prepare for increase in attacks
• For Special Incidents such as espionage, inappropriate use, or sexual harassment, take appropriate actions determined by the type of incident
• In the Incident Record Keeping Phase you complete legally acceptable pre-built forms to document and report the incident
• In the Incident Follow-Up Phase you conduct a lessons-learned meeting and define appropriate changes in process for the future

• Network-level Attacks such as session hijacking (from Telnet to SSL and SSH), person-in-the-middle attacks, and passive sniffing
• Gathering and Parsing Packets via active sniffing through ARP cache poisoning and DNS injection, DNS cache poisoning to redirect traffic on the Internet, using Netcat for backdoors and Nasty Relays, and IP Address spoofing
• Operating System and Application-Level Attacks utilizing buffer overflows, the MetaSploit Exploitation Framework, the Perl Exploit Library, and format string attacks to exploit vulnerabilities in Windows
