You can easily write one, for example if you want to open port 80 for 5 minutes:<br />
<br />

<pre><code id="code-20-41017215-1">#!/bin/bash
iptables -I INPUT -p tcp --dport 80 -j ACCEPT
sleep 300
service iptables restart</code></pre>
<br />
The above will add a rule to open port 80, then wait 5 minutes and restart iptables to remove the rule.

The Linux operating system, in all its flavors, has its own share of security flaws that allow intrusions, but there are various mechanisms by which these flaws can be removed, generally divided into two parts: authentication and access control. Authentication is responsible for ensuring that a user requesting access to the system is really the user with the account, while access control is responsible for controlling which resources each account has access to and what kind of access is permitted.

Linux Security

Linux is a UNIX-like open source operating system with hundreds of distinct distributions, including: Fedora, openSUSE, Ubuntu, Debian, Slackware, Gentoo, CentOS, and Arch Linux. Linux is generally associated with web and database servers, but has become popular in many niche industries and applications.

The variety of Linux distributions creates myriad issues relating to configuration and operations when computers are networked, not the least of which is the use of various network management applications, some of which are included with specific distributions, while others are standalone applications.
