Data security should be amongst the most important protocols for any company. 70% of small organisations believe they are safe from the targeting of data theft or misuse. This is very rarely the case. If your organisation holds data on individuals or companies, you are a target for data theft, no matter your company size or industry.
Being a victim of data abuse can severely damage your company’s reputation in the short and long term. If the data theft results from your negligence, you can even face prosecution.
There are many ways to prevent data interception and theft; if you follow these data security measures, you will mitigate the chances of your data being compromised:
Top tips to prevent data interception and theft
1. Make sure your employees have the appropriate training
Untrained staff can lead to innocent mistakes, which, in turn, can cause dangerous data breaches. In fact, 88% of UK data breaches are caused by human error. Only 12% of data breaches result from malicious attacks – UK’s Information Commissioner’s Office (ICO). By making training mandatory, you can ensure that all your staff understand the importance of data security and comply with the processes you put in place. This will greatly reduce the chances of individual errors.
2. Use strong password protection and two-factor authentication
Have strict rules on the format of passwords and encourage staff to use random words rather than words with personal resonance. For extra security, put systems in place that ensure these are changed every two months and that they cannot use the same password again. Where possible, always use 2-factor authentication to log in to any system you have that contains sensitive data.
You could also use a password managers browser extension like Dashlane, LastPass or Keeper Security. These all have two-factor authentication, allowing you to create random passwords and save them to your password vault.
3. Identify and classify sensitive data
Identify different types of data and, in terms of how sensitive it is – categorise this data. By prioritising data in this way, you can grant and restrict access to employees where necessary, thus reducing the possibility of data interception.
For example, financial data might only need to be granted to the finance department, or client communication might only be necessary for the sales team.
4. Properly dispose of sensitive data
Physical documents will need to be shredded to ensure the data is illegible. When getting rid of your devices – such as work phones, laptops, tablets or computers etc., all data must be wiped before they are disposed of or recycled.
5. Encrypt sensitive data
You could consider encrypting all the data on your laptop or computer; however, if you feel this is too extensive, you may choose to only encrypt files with the most sensitive data. Any data that is being transferred or emailed needs to be encrypted.
6. Be cautious with employees using personal devices
Whether it’s your staff bringing in personal devices or visitors and clients bringing in their devices for a meeting, ensure they are connected to a different network than your company computers. External devices can be infected with malware, and the owner may be unaware that their device is infected. Sensitive data can be stolen if the device is connected to corporate networks. You might consider implementing a BYOD (Bring Your Own Device) policy to ensure staff are aware of appropriate use.
These methods of data security management are important steps for your organisation to follow, and none are too complicated for any business to carry out. If you take data theft seriously, implementing ISO 27001 will ensure you have systems and processes in place so that you can ensure your data is highly secure.
