OT Security Standard IEC 62443

The IEC specifically made IEC 62443 with reference to ISA 99 standard for industrial control security. ISA/IEC 62443 has different series of standards, allowing upstream, midstream and downstream manufacturers in each industrial control field to have their own corresponding standards, without the need to apply to all manufacturers. This approach enables manufacturers to reduce the cost and manpower of introducing cybersecurity standards. Meanwhile, it can quickly find out the cause and take appropriate measures when a cybersecurity incident occurs.
