The advent of the internet has allowed for vast amounts of information to be transferred between private networks, by allowing data transfer from personal computers, through their associated gateways, to the vast interconnected networks of computers beyond.The systems used to store and send data can be compromised, and due to this, the security requirements on sensitive information, demanded by the public and private sectors, have never been higher. The increasing notoriety and media attention of the hacking of private information, by exploiting the weak points in network protocols, are only serving to increase this demand.Additionally, there are new network models that show great potential, but are also far more vulnerable to specialised attack. Tackling these issues, there are now high level courses, such as CISSP courses, which bring the teaching of data and systems security to a new level of insight.Modern VulnerabilitiesAs the world moves on from physical data storage (President Obama has recently introduced the law for all medical records to be made completely virtual by 2013), high-level security certifications will become crucial for companies and organisations. As a result, federal data security is currently a major area of job growth.Modern developments, such as virtualisation and cloud computing, boast superiority over former networking, since computations and data storage are no longer handled by each individual computer, but by the ‘cloud’ itself.Centrally stored information, as opposed to individual computers holding separate files, leaves the entire network vulnerable if the security of the cloud is compromised. Advanced training, such as CISSP training, teaches with the frontiers of system developments in mind. The need for a global security standardThere are two major areas of security to be addressed. In the interests of information security, there is a crucial need for:state-of-the-art security architecture and protocols a global platform of information security expertise for both the public and private sectorsThe first point is a result of the increasingly complex nature of networking. The second point highlights the need for employees to have expertise in key areas, and show competence in all areas of data systems security. The content of CISSP courses address the key technical areas of:security models, developments, and management
encryption standards (such as AES)
system architecture and functionsFurther insight is gained with non-technical, but equally important modules, such as law, ethics, teaching, and physical security. Encryption has been around for as long as there have been messages to send, and today there are many advanced encryption methods, and knowing modern encryption methods is a very important topic.In general, the rapid advance of system architecture and exponentially increasing speeds and volumes of connectivity, are ensuring the need of security standards for employees. The insight gained through CISSP training will become a very important, and highly sought after qualification, as federal data security moves towards the application of a systems defence standard in the near future.
