Firewall Solutions

It is important to understand that once network connectivity is put in place a risk is created and the implementation of firewall devices seeks to minimise those risks. Kerna has been developing security solutions for its clients for over fourteen years using a diverse range of products. These solutions have used leading edge product such as Checkpoint, Sun, Juniper, TIS, Network Associates and CISCO across sectors such as Banking, Government, Insurance and Health.

Typically a security project consists of three major phases:

• Policy development, the site security policy must be developed so that the security requirements can be derived. It is strongly recommended that a formal security policy document be produced but at a minimum a written specification should be produced.
• Security implementation, firstly site resources must be protected through a resilient set of firewalling measures. However, this implementation process may also include user management and application specific measures such as virus scanning, content striping and audit trails.
• Audit, any large scale security implementation will generally also include an audit phase which often is undertaken as an independent exercise by a different implementor from the main security project. Such audits are an important part of maintaining ongoing security and typically might take place every six months.

Through our consultancy and implementation groups we can satisfy all aspects of a security project.

More recently companies have struggled to maintain an effective set of controls as the dynamic nature both of their business and the technologies underlying that business stretch the capabilities of traditional static firewall solutions. Increasing compliance and internal service level agreements cannot be met by existing security architectures and investment. Kerna can assist companies introduce new concepts to the security team to address these issues through dynamic tools for data and systems managment and security.
