In end-to-end security, it’s important to consider that the chain is only as strong as its weakest link. That is why it is essential that an access control system is always evaluated in its entirety, to discover where the weakest link can be found.
It is not uncommon for access control systems to be installed and then used for the longest time possible without any attention to updating the system’s intrinsic security features. There are many systems in the field that are over 10-years old, based on technologies much older than this and with no or very low cyber security protection.
Some ‘weak-links’ might be strengthened by new encryption methods, others by good process and some only by partial or entire replacement. What is essential is that for those considering investing in new technology, not to introduce weak-links.
