App-waf，一个简单的waf模块。
用来实时探测web非法访问，统计非法访问的ip，web状态，访问url，来源weburl。结合iptables可以实现实现实时封禁。
实例说明见example目录（包括日志）
use App::Waf;my $filename = "example.acess";#日志文件my $numlines = 50000; #要处理的行数,从后读。my $line=tail($filename,$$numlines); ($log,$zcount,$zip,$zrequrl,$zstatus,$siteurl)=initCount($line);print "==============Attack Summary ==================\n";print "\nThe total attack count: $zcount \n";print "\nThe count from source IP: \n\n";print "$_\=> $zip->{$_} \n" for(sort keys %{$zip});print "The count From request Url: \n\n";print "$_\=> $zrequrl->{$_} \n" for(sort keys %{$zrequrl});print "\n\nThe count From Http Status: \n\n";print "$_\=> $zstatus->{$_} \n" for(sort keys %{$zstatus});print "\n\nThe count From Site Url: \n\n";print "$_\=> $siteurl->{$_} \n" for(sort keys %{$siteurl});结合nginx和iptables进行实时banip的实例（example/banip.pl）
加入crontab每5分钟执行一次。
echo "*/5 * * * * perl $dir/banip.pl >> bianip.logs 2>&1 " >> /var/spool/cron/root结果展示
