Individual
As a user it is your responsibility to be a smart user when on a network as human error is the most common threat to anyone on a network. Individuals are their own worst enemy online and it will be through their own fault that their data is breached. To be secure as an individual you should consider
- Secure passwords (Possibly encrypted)
- Knowing about the types of attacks used by hackers to breach a network
- Taking physical security into consideration(not leaving yourself logged in, not leaving USB’s in PC’s)
Business
As a business you are not just in charge for your own security but also the security of every user on the network and the customer data stored on your network. Every precaution must be taken to ensure the risk of a breach is minimal. A business must take all possible threats into consideration and have steps to counter/prevent attacks coming into the business. A business should consider
- User authentication for log-ins
- A network proxy to deny any requests to malicious sites
- A firewall(hardware and software) to protect more valuable assets such as databases
- Patching systems so they are less vulnerable to OS problems
- securing hardware physically
