Note about IT Security: OS/2 has very few native computer viruses; while it is not invulnerable by design, its reduced market share appears to have discouraged virus writers. There are, however, OS/2-based antivirus programs, dealing with DOS viruses and Windows viruses that could pass through an OS/2 server. The RI System controller has reduced exposure due to being deployed behind corporate firewalls and on production floors with limited internet access. For concerns about malware and virus prevention, see RI System Software - Security and Anti-Virus document.
