When an organisation wishes to get to grips with its network security a holistic approach is required. Most networks will have to support a number of different systems, which means the network is only as strong as its weakest link.
One aspect of network security is identifying where your current perimeter lies, as over time your network will evolve. This understanding provides a foundation and blue print from which we can support any organisation improve on their existing IT security. The main idea from strengthening a network's security is to ensure the protection, usability, reliability, integrity, and safety of your network and data. Effective network security targets a variety of threats and stops them from entering or spreading throughout your network.
One goal of any security policy will be to secure the access of valuable data and resources, without restricting user's ability to effectively work and support in the growth of their organisation. There is a fine line between securing a network and restricting organisational growth, and in today's face pace world this balancing act is vital.
In network security it is crucial to understand that no one single solution can protect an organisation from a variety of threats. The need to maintain multiple layers of security is essential. Assuming one layer of defence fails, the others are there to compensate.
Network security is achieved through both hardware and software working in harmony. All security software requires continual updating in order to protect from emerging threats.
Once you have put in place a range of ridged security solutions you need to put it to the test. By being proactive and testing you networks capabilities before a real attack occurs is essential. Penetration Testing will give you this real life scenario and demonstrate where weaknesses lie, allowing alterations to be made.
