Because security is so broad, it’s difficult for big companies to decide which security practices they should use. Some security practices should be considered, especially for people working with sensitive data like card information. These include:
- Carrying out risk assessments. This will allow the business to figure out the answer to certain scenarios. These include the likelihood of attacks, and what the attack would cost the company.
- Putting security policies in place for employees. An example could be updating employee passwords every 30 days. Or, running antimalware over every device in the company.
- Putting physical security measures in place. This might look like security guards for the building, or swipe badges for printers.
- Putting human resource security measures in place. This gives an organisation a better understanding of who is working for them.
- Carrying out backups. Carrying out and testing backups prevents ransomware attacks that may occur.
An important thing to consider when thinking about security in a company is how educated your staff are. For example, there is no use making employees update their password every 30 days if they use a weak password or they write their password down on a sticky note which they leave on their desk. So, as well as security policy, you need to educate the users on how they can protect themselves in the business. This could be a course to help them identify fraudulent emails, create secure passwords, and manage the data they put out online.
Cybercriminals will often carry out a specific sequence of events known as a cyber kill chain. We can analyse these steps and put devices in place to stop them from progressing through the chain. To conclude, even though security can be complicated for large businesses, it is useful to ensure data is secure and cost losses are minimal.
