IPsec (IP security) is a standardized framework for securing Internet Protocol (IP) communications by encrypting and/or authenticating each IP packet in a data stream. There are two modes of IPsec operation: transport mode and tunnel mode. In transport mode only the payload (message) of the IP packet is encrypted. It is fully-routable since the IP header is sent as plain text; however, it can not cross NAT interfaces, as this will invalidate its hash value. In tunnel mode, the entire IP packet is encrypted. It must then be encapsulated into a new IP packet for routing to work.
This report arms you with the knowledge and insight you need to make more informed business decisions when it comes to the security of your organisation.

Small businesses, representing companies with fewer than 500 employees, represent 99.9% of all employers in the UK1, and 99.7% of US employers2. As such, they are a substantial economic driver, and can be considered part of the critical national infrastructure, meaning that their security readiness is a significant issue. As a leader in the campaign to secure companies of all sizes against cyber attack, Web security company Webroot undertook a survey to help increase the understanding of small to medium-sized business (SMB) security awareness and readiness. Webroot sampled businesses across the US, the UK, and Australia, and used responses from organisations of various sizes to help gauge the security stance of SMBs in context.

Computer and networking technologies continue to evolve rapidly, enabling previously unthought-of ways of communicating and collaborating with our peers, suppliers and clients. Unfortunately, they have also created new opportunities for cybercrime - the bad guys are using the distributed power of the internet to maximise their reach and impact. From an IT security perspective we still follow approaches and practices that are more than two decades old. The old models neither support today's business activities, nor do they protect against the sophisticated and highly targeted attacks that are becoming prevalent.
