Security Consulting — Request Bid

While the Internet has created new opportunities for companies to streamline business processes, enter new markets, and work with partners and customers more effectively, it has also created a greater reliance on networks and a need to protect against a wide range of security threats. The most important element of any network security solution starts with a clear understanding and working relationship between a company’s business and technology teams. Without proper protection, any part of any network is at risk for security breach or unauthorized activity from hackers, competitors, or even employees.

Security is a Path not a Destination
Security is a matter of degree, rather than an absolute state. Further, there is no single product, person or policy that can provide security. The right way to approach security is incrementally. Any company can improve its level of security by following a simple, three-step process:

• Develop policies and requirements
• Implement solutions
• Audit the results

This closed-loop process, repeated over and over, will lead to continuous improvement in a company's security level.

Solutions
Ensuring that networks and systems do not have security vulnerabilities is critical to minimizing risk. Usually, the first step is to create a formal security policy statement that outlines the rules by which users are entitled to access online corporate resources. This policy, which must be supported by executive management, serves as the basis for a company’s security-design process. Because business requirements and security technology are constantly evolving, companies should update these policies at least once a year.

When developing security policy, it’s important to remember that it’s not just about having the right technology and equipment in place, but also ensuring that the traffic passing through the equipment is maintained and monitored. Companies need to include policies for authentication to ensure that only authorized traffic moves through the network.

Security solutions cover a wide range of products and address different aspects of protection, including the following:

• Access Control: Access controls validate the user’s identity and determines entitlement to information and applications based on user profiles. Authorization and privilege management depend on directories that include user, process, and object security attributes based on security policies and business rules. Authentication methods range from simple password systems to biometric devices that scan physical characteristics such as fingerprints.
  
  
• Firewall: A firewall blocks intrusion attempts and allows only authorized users to enter—the digital equivalent of a locked door. Using a predefined security policy, a firewall is a hardware or software solution that acts as a barrier to crossing a network’s perimeter, allowing only authorized traffic to pass.
  
  
• Encryption: Encryption ensures that messages cannot be intercepted or read by anyone but the intended recipient. As more information travels over public networks, the need for encrypting the information becomes more important. Companies can implement encryption at both the network and application-to-application layers.
  
  
• Intrusion Detection: An intrusion detection system analyzes network activity, detects security breaches, and sends alarms to administrators across the network. By monitoring network and transaction activity, companies can detect attacks at different levels.
  
  
• Network Scanning: A network scanner conducts detailed analysis of network activity to identify potential vulnerabilities. System-integration and consulting firms can do high-level assessments, and companies can do their own regular scans to identify more common problems that can be addressed in-house or referred to outside experts.
