Information security is the process of protecting the availability, privacy, and integrity of data and describes measures and methods taken by a company to increase the security in the equipment and network storing the information. Integrity means that data cannot be modified undetectably. Integrity is violated when a message is actively modified in transit or when data is tampered with and changed during storage. Information security systems typically provide message integrity in addition to data confidentiality.
Information security must protect information throughout the life span of the information, from the initial creation of the information on through to the final disposal of the information. The information must be protected while in motion and while at rest. During its lifetime, information may pass through many different information processing systems and through many different parts of information processing systems. There are many different ways the information and information systems can be threatened. To fully protect the information during its lifetime, each component of the information processing system must have its own protection mechanisms. The building up, layering on and overlapping of security measures is called defense in depth. The strength of any system is no greater than its weakest link. With a defense in depth strategy in place, should one defensive measure fail then there are other defensive measures in place that continue to provide protection.
Our goal is to offer guidance to investor and financial institutions seeking to understand this field. Our staff can organize and implement a supervised evaluation of the security of a computer system or network by simulating an attack from malicious outsiders (who do not have an authorized means of accessing the organization's systems) and malicious insiders (who have some level of authorized access). This analysis is carried out from the position of a potential attacker and can involve active exploitation of security vulnerabilities. Our staff can:
- Conduct a determination of the feasibility of a particular set of attack vectors;
- Identify higher-
risk vulnerabilities that result from a combination of lower- risk vulnerabilities exploited in a particular sequence; - Identify vulnerabilities that may be difficult or impossible to detect with automated network or application vulnerability scanning software;
- Assess the operational impacts of successful attacks and outline a range of technical & procedural countermeasures to reduce risks.;
- Test the ability of your staff of network defenders to successfully detect & respond to the attacks;
How can we help you?
