Server Security - Secure Your Website using. Htaccess file

What is .htaccess file

.htaccess files provide a way to make configuration on a per-directory basis. In the .htaccess file, we provide directives to apply a configuration.

When to use .htaccess

Generally, this file should be used when you have no access to your server configuration file (httpd.conf).

The best example would be shared hosting providers where you don’t get root access to make changes in httpd.conf file. In such scenarios .htaccess plays a very important role.

In shared hosting, we make .htaccess files to secure our websites. We create this file on each directory to secure it from hackers or attackers.

When to avoid .htaccess file

We should not use this if we have access to our main configuration file.

There are two main reasons to avoid the use of .htaccess file.

The first of these is performance. When AllowOverride is set to allow the use of .htaccess files, httpd will look in every directory for .htaccess files. Thus, permitting .htaccess files cause a performance hit.
The Other reason is .htaccess file is loaded every time a document is requested.  

One should go with .htaccess file only when there is no other option left.

How to create .htaccess file

Step 1: Go inside the root directory of your website. And then create an empty file with the extension .htaccess

So now website folders are looking like this

Website Directory

Hide Server Details On Page Footer

First, we will hide our server details on footer which gets visible when error pages get displayed. To do this I will add the ServerSignature directive and set its value to Off. The ServerSignature will hide the server details on the footer.

Website - Page not found with footer

Thus, we will add the below line then save the file and restart the server.

ServerSignature Off

Website - Error 404 Page not found

Hide Directory Listing

When there is no default file is available in the directory which is generally index.html or index.php then the server gets confused which file to show and it displays all the files and folders. This is quite dangerous because if an attacker finds this then they can misuse the data.

when no default file is available it displays contents like this

Website directory structure

In order to hide the content, we will add the below line save the file, and restart the server.

Options -Indexes

Website directory structure hidden
Directory is no longer visible

In this article, we have seen the other way of securing our website when we do not have access to the server main configuration. I hope you have learned something new with this article.

Automation - Update Naukri Profile Using Selenium

Recently one of my friend came to me with a problem. He is looking out for new job but he feels quite boring to update  his profile on daily basis. As some people says updating profile in the morning gives you more calls as it keeps the newly updated profile on top (Although i don’t know whether naukri works this way or not 😀 ). As i was more interested to solve his problem.  After listening his problem i came to solution that instead of updating it manually lets make this job automatic. And it is quite interesting how we can automate our daily boring task with automation. Another day i came with the solution . And the solution was to make it automatic using selenium (Those who are not aware about selenium do check this link) In short, Selenium is a Testing automation Framework. And it is for automating web applications for testing purposes, but is certainly not limited to just that. Boring web-based administration tasks can (and should) also be automated as well....

OpenCV - Image Filters

Hello Guys, In this tutorial, I will discuss the color map in OpenCV. Color Map is used to show different color temperatures. And this can also be used to generate some cool image filters.  OpenCV comes with thirteen built-in color maps. So in this tutorial, I will show you how to use color maps.  Let’s get started List of Color Maps COLORMAP_AUTUMN COLORMAP_BONE COLORMAP_JET COLORMAP_WINTER COLORMAP_RAINBOW COLORMAP_OCEAN COLORMAP_SUMMER COLORMAP_SPRING COLORMAP_COOL COLORMAP_HSV COLORMAP_PINK COLORMAP_HOT COLORMAP_PARULA To apply color map first we need to convert an image to grayscale. So I will use  img = cv.imread("nature.jpg",cv.IMREAD_GRAYSCALE) If you are not aware of this function then please check my previous tutorial  http://techievaibhav.in/2019/01/10/reading-an-image-using-opencv/ To apply color maps, OpenCV comes with a function called applyColorMap() . This function takes two parameters. Gray Scale image Color Map Autumn Bone Cool Hot HSV Jet Ocean Parula Pink ...

Android - Show A Dialog From Service

In this article, I will be discussing how you can create a dialog from service. As we all know that service in android does not have any UI and it is intended for long-running background tasks. But sometimes it is required to show some information to the user when your app is running in the background. Today I will show you how you can implement this type of functionality in your application. Before starting the tutorial let me tell you about the special permission that we are going to use. Permission AndroidManifest.xml<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/> This permission allows the app to use the system level window. AndroidManifest.xml <?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.app.dialogfromservice"> <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/> <appl...
