1.12 deraadt 18: <h3><font color=#e00000><strong>OpenBSD Security Views</strong></font></h3>
1.14 deraadt 19: OpenBSD believes in strong security. Our aspiration is to be NUMBER
20: ONE in the industry for security. Due to our open software
21: development model, we are able to take a more uncompromising view
22: towards increasing security than Sun, SGI, IBM, HP, or other vendors
23: are able to.
1.12 deraadt 24:
25: <p>
1.13 deraadt 26: Like most members of the
27: <a href=http://www.geek-girl.com/bugtraq/index.html>
28: BUGTRAQ mailing list (which rarely sees OpenBSD security reports
29: these days :-)</a>,
30: we believe in full disclosure of security problems. We have found
31: that the coding of proper fixes to security problems typically only
32: requires about 4-5 minutes of coding. Thus we typically have fixes
33: available extremely quickly.
34:
35: <p>
1.15 ! deraadt 36:
1.12 deraadt 37: Our security auditing team typically has between six and twelve
1.15 ! deraadt 38: members, and most of us continually search for and fix new security
! 39: holes. We have been auditing since the summer of 1997. The process we
1.12 deraadt 40: followed to increase security was simply a comprehensive file-by-file
41: analysis of every critical software component. Flaws were found in
42: just about every area of the system. Entire new classes of security
43: problems were found while we were doing the audit, and in many cases
44: source code which had been audited earlier had to be re-audited with
45: these new flaws in mind.
46:
47: <p>
1.15 ! deraadt 48: Our security auditing proces is a proactive one. In almost all cases
! 49: we have found that exploitability is not an issue. We have fixed many
! 50: simple and obvious careless programming errors in code and then only
! 51: months later discovered that the problems were in fact exploitable.
! 52: The proactive auditing process has really paid off. Statements like
! 53: ``This problem was fixed in OpenBSD about 6 months ago'' have become
! 54: commonplace in security forums like BUGTRAQ.
! 55:
! 56: <p>
1.14 deraadt 57: The auditing process is not over yet, and as you can see we continue
58: to find and fix new security flaws.
