Auditing

I can provide:

I can provide monitoring for many aspects of system abuse:

• inappropriate use of equipment by employees

Firewalls & VPNs

OpenBSD makes an excellent firewall, and includes a lot of security-oriented software.

I can install, configure & support the following:

• IPsec IP security protocol (used to create VPNs)
• OpenSSH ssh secure shell, tunneling etc
• The PF packet filter
• The spamd spam deferal daemon (a 'tarpit' used to slow spammers down)

Mail, spam & virus filtering

An OpenBSD box can be used to protect your existing mail server, or replace it completely.

I can install, configure & support the following:

• Sendmail mail server
• BMF baysian mail filter

• Vipuls Razor distributed, collaborative spam filtering
