Proxy Firewall and Gateway Firewall: Introduction

Posted on June 28, 2010 by Ganesh Sharma

The terms proxy firewall and gateway firewall are used synonymously. These firewalls help to maintain the transparency between the requester and server. As you know, the packet filter firewall inspects the headers of the packets, so it works at network transport layer. But to do inspection of packets at deeper level for better security, we need the proxy firewalls which works at application layer. Moreover, these firewalls are aware of the application protocol, so they provide better inspection capabilities.

Packet Filtering Firewall: An Introduction

Posted on June 27, 2010 by Ganesh Sharma

The Packet Filtering Firewall is one of the most basic firewalls. The first step in protecting internal users from the external network threats is to implement this type of security. The first ever firewalls used were of packet filtering type only. As the trends of network threats started changing, so did the firewall building strategies. Most of the routers have packet filtering built-in, but the problem with the routers is that, they are difficult to configure and don’t provide extensive logs of the incidents. In my previous firewall tutorials I talked about firewall policies and few other things. That information is also used while designing such firewalls.

Firewall Security Policy

Posted on June 26, 2010 by Ganesh Sharma

For network security there are some rules which we covered under security policy. The firewall policy is altogether different. We must say that security policy resides at conceptual level and firewall policy resides at technical implementation level and is a subset of security policy. Here I am going to discuss the firewall policy which covers theoretical implementation of network security policy.

Desired Security Policy For Firewall Implementation

Posted on June 25, 2010 by Ganesh Sharma

For IT security when it comes to implementation of firewall, the planning comes first. The base of planning is the security policy for your organization. The firewall should be capable enough to protect the LAN resources from harms on internet. In a recent article on introduction to firewalls, I discussed about firewall basics. Now I’m going to discuss about the desired security policy for the firewall implementation for your network.

How Linux Systems Security is Compromised

Posted on June 23, 2010 by Ganesh Sharma

The situation becomes even more dangerous when the suid/sgid programs are poorly written. e.g when suid programs are written, then at the run time the privileges are elevated. Now, if the programmer forgets to drop the privileges then the root privileges are retained by the program.

Day 28-Working With Joomla Tools Menu

Posted on June 18, 2010January 17, 2019 by Ganesh Sharma

Yesterday I wrote about Cache Manager in article Day-27.Today I will write on Purge Expired Cache next to Cache Manager under tools, What is Purge Expired Cache and how it works. Let’s start with the definition of Purge Cache Manager!
What is Purge Expired Cache?

Click on Tools menu at joomla administration backend and you will see Purge Expired Cache in sub menu. Click on this menu. You will see screen as shown below:
This tool will purge all expired cache files from the cache folders. Cache files which are still current are not purged.

* Because this process has to check each cache file individually, it is slower and requires more system resources than the Clean Cache option. However, once the purge process is complete, there should be no loss in speed for users of the site, because all current cache files are still available. In contrast, the Clean Cache option runs more quickly, since it just deletes all of the files in each cache folder. However, the website may be a little slower
