When you’re building a network, keeping all of your information secure is not only important but a legal necessity.
Find out how network technologies can enhance security and why it’s such an important part of doing business.
Why is network security important?
Network security means that your data remains in a controlled network, only seen by people with permission to do so. Not only does this help staff and clients to feel more secure, but it’s a legal requirement. GDPR (General Data Protection Regulations) and other associated legislation mean that people have a right to know how you process their data, who sees the data and what specific data you possess. By emphasising network security, you not only make your customers feel safer and happier with your service, but you protect yourself from any potential legal issues.
What are you trying to protect
Understanding what you are trying to secure and from what threats is an important starting point. Once that is established, you can begin to look at ways to protect your assets. This leads onto the idea of ‘Defence in Depth’. This is the technique of using multiple layers of protection, this ensures that if one layer fails other layers are still effective.
How to ensure network security
There are a few ways to ensure network security, the first of which is by creating a network that has layered security as suggested above. Use layers of security to protect your resources, as this makes sure that if one layer isn’t successful, the others can help to retain a secure network. A second approach is to break the network up into zones using VLANs (Virtual Local Area Network). You could implement a guest VLAN such that temporary visitors only get outbound access to the Internet. Internal networks can be split up according to work function, such as separating developers from normal staff.
Human factors
Training and promoting good practices amongst all employees is a crucial step, once your network is secure, the next weakest access point will be yur staff. Good cyber-security starts with staff members being more responsible and being aware of problems like scams and social engineering.
Retain accessibility
Whilst having a secure network is important, you still need to achieve a workable balance for accessibility. This means the right people having access to the right data when they need it. A totally secure network that prevents all access can effectively paralyse a business, limiting functionality and making customer service more difficult. Focus on good security processes and techniques, ensuring your employees have a clear route to the information they need, with appropriate levels of access and audit logging built into the system.
