Network Security Services Information
Network security services assess the vulnerability of networks to attack, design and manage firewalls, and install and upgrade anti-virus software. Managed services include network intrusion prevention, host intrusion prevention, email encryption, email filtering, and firewall management. To prevent network intrusions, network security consultants use software to inspect network traffic for malicious code or unusual patterns. Packet inspection can block targeted and random attacks in real-time. To prevent host intrusion, network security services build an application firewall that protects servers from both internal and external attacks. Email encryption protects confidential information such as medical records and project costs. Email filtering identifies spam, removes viruses, and quarantines suspicious email. Firewalls allow authorized users to access network resources via a virtual private network (VPN). Network security services that provide firewall management and monitoring perform a site assessment, design a firewall policy, install and configure network equipment, and review logs and other reports on a periodic basis.
Network security services provide professional services such as risk analysis, regulatory compliance, penetration testing, phishing prevention, and web application assessment. Risk analysis or gap analysis establishes security benchmarks and defines network management practices. Examples of regulatory compliance include critical infrastructure protection (CIP) for utilities and Health Insurance Portability and Accountability Act (HIPAA) gap analysis for healthcare providers. Penetration testing is designed to subject a network to real-world attacks such as structured query language (SQL) injection. Anti-phishing services provide both countermeasures and coordination. Web application assessment protects web-based assets from cross-site scripting attacks, the malicious use of user IDs, insecure configuration management, improper error handling, non-validated inputs, buffer overflows and denial of service attacks. Network security services can also help businesses prepare for audits.
Network security services are located across the United States and around the world. They help protect banks, hospitals, insurance providers, and government web sites from targeted attacks by hackers. Technology partners include providers of network security software and hardware. Network security services also work with organizations such as the Internet Security Alliance, the Forum of Incident Response and Security Teams (FIRST), and the Watch and Warn Committee of the U.S. Federal Bureau of Investigation (FBI).
