そのまま書き換えてみました。

#!/usr/local/bin/ruby

e = [   'BAD-TRAFFIC loopback traffic',
        'ICMP PING CyberKit 2.2 Windows',
        'MS-SQL',
        'WEB-CGI count.cgi access',
        'WEB-FRONTPAGE /_vti_bin/ access',
        'WEB-IIS',
        'WEB-MISC robots.txt access',
        'SCAN Proxy (8080) attempt',
        'SCAN SOCKS Proxy attempt',
        'SCAN Squid Proxy attempt',
        'SCAN UPnP service discover attempt',
  ].collect {|v| Regexp.quote(v)}
p = Regexp.compile(e.join('|'))
s = open('/var/log/snort/alert').read()
r = s.split(/\n\n/)
for x in r
    if  p.match(x)
    else
        print x + "\n"
    end
end

少し、Rubyらしく(というより好み?)しました。この程度じゃそん
な差は出ませんね。

#!/usr/local/bin/ruby

e = [   'BAD-TRAFFIC loopback traffic',
        'ICMP PING CyberKit 2.2 Windows',
        'MS-SQL',
        'WEB-CGI count.cgi access',
        'WEB-FRONTPAGE /_vti_bin/ access',
        'WEB-IIS',
        'WEB-MISC robots.txt access',
        'SCAN Proxy (8080) attempt',
        'SCAN SOCKS Proxy attempt',
        'SCAN Squid Proxy attempt',
        'SCAN UPnP service discover attempt',
  ].collect {|v| Regexp.quote(v)}
p = Regexp.compile(e.join('|'))

s = File.read('/var/log/snort/alert')
s.split(/\n\n/).each {|x|
  puts x if p !~ x
}
