How Can Physical Security Improve Cyber Security?

Many people believe that physical security and cyber security are two independent entities. However, the two are closely connected. Cracking down on physical security such as CCTV, alarms, and locks, ensures your environment is impenetrable, which can largely diminish the threat of a digital data violation.

If you’re wondering how physical security can help improve your cyber security, we have listed our top five physical security tips that we recommend.

1. Make Sure All Security Systems Are In Order

There is nothing worse than finding out CCTV cameras were not working at the time of the crime. Set them up in the most crucial areas, specifically where important documents or equipment is held not just outside of the building.

Carry out weekly checks to confirm that all systems are fully functioning and not at fault. It could save a lot of time and money in the future.

3. No Unauthorised Visitors

Provide ID badges upon entry so visitors are easily identifiable and no one without authorisation can gain access to the premises.

Have a log at reception so anyone who enters will have to sign their name and what date and time they arrived and left. This is a good way of keeping track of people entering and exiting your site. Having gatehouse security is a great way of monitoring and controlling access.

4. Encrypt Data

Encrypted data, usually known as ciphertext, is a very popular form of protection in security programs. Data encryption is information that has been translated into another form that can only be accessed by those who possess the correct encryption key.

We now live in a digital world where most information is inputted through online systems, however, this can leave you vulnerable to hackers. Encrypting emails and online systems where sensitive information is stored will be a great way to prevent this.

5. Hardware And Document Disposal

Simply throwing things in the bin will not suffice. Any documents that are no longer needed should be shredded and disposed of immediately. Over time hardware will need to be updated or replaced so you have the newest and most secure devices.

Old equipment, especially hard drives which will contain classified information, will need to be disposed of correctly and by a dependable security firm.
