In the world of electronics, the word "brick" describes electronic devices that have a serious misconfiguration, corrupted firmware or a hardware problem, can no more function.

We can't call a device that have a problem we can easily solve a "bricked device" ,  such as a computer that needs only a format or a computer device that needs a bios upgrade or a driver to function.
Let’s say we tried to update the firmware of the bios or the HDD or any hardware, and this update is corrupted, that can cause a misconfiguration of these devices, and can no more function, because the firmware stored in the ROM is damaged; now we can talk about a bricked device.

Most of the time, updating a firmware is one of the most common causes that "brick" your device.
let’s say while firmware updating, you turned off your device, or you unplugged it from computer - if you update your device from computer"- there is a big chance to "brick" your device, this is what u need to avoid if you are updating firmware, that's why we see this kind of phrases during the upgrade "warning: DO NOT turn off the power switch...".



What u need to do if your device is bricked:

1-  use recovery mode, although this option is not available in all computers, specially the old ones, and for IPhones there is an alternative option called DFU MODE.

2- call your device manufacturer to repair or change your bricked device, if the problem is caused by an official firmware update...

3- JTAG method, it  is not simple for simple users but it's the best way to repair and store back the firmware back in the device ROM, it's advised to go to a specialist to carry of JTAG process


Remember: Be careful while doing firmware update...

Security of a website can't reach 100%, hackers always find new vulnerabilities and they exploit it to attack systems and applications. But you can improve your website security and decrease the chances of getting hacked by following these advices.

For the webserver:

1- choose a web server in mac, mac have more security than Linux, Linux have more security than Windows.

2-if you have a personal server in your computer like big companies have more security than a host servers,

3-a website hosted in a virtual machine (VPS) have more security than a website hosted in a simple machine.

4-the operating system and the applications where the webserver is running, should always get last security updates.

5-the webserver should have antivirus and Anti-DDOS attack protection.

6-the webserver should have a firewall against malicious requests.

For the web application (script):

1- if u use a downloaded script, use the one that have good support and updates, and don't use a lot of (Add-ons, plugins, modules ,gadgets), less add-ons means less vulnerabilities.

2- if the web script is developed by you from zero, you need to know that bad programming means more vulnerabilities

3- your web script should be programmed to crypt passwords(md5,sha-1,DES...), and u have to use a hard password for your admin account.

4-the password of your admin account should be different than the (cpannel, ftp, phpmyadmin, mysql...) passwords.

5- change the path and the name of the website administration's folder, and if u have Cpannel you can give a password for this folder.
ex: www.yoursite.com/admin/index.php
www.yoursite.com/folder/folder/../adminwebfolder/index.php

this needs also to modify some codes in your script

6-use a website vulnerability scanner, like Acunetix wvs or nikto... to know if your website is vulnerable to attacks like (sql injection, local file include, remote file include, authentication bypass, buffer overflow, XSS, CSRF...).

wampserver is marked online, but his icon in notification area is orange, that's means there is a problem to connect to the appache server service, so u need to check httpd.conf file's settings in apache menu, but most of time if u didn't touch this file the problem is due to port conflict.


just close the application that uses the same port as apache(port 80),or change connection settings of this application, we are not talking here about browsers.


for example if you are running skype and you got this problem just follow this steps.

methode(A):1- close skype.

methode(B):

1- in the menu bar of skype click tools then options
2- in the skype options left side click advanced then connection.
3- uncheck "use port 80 and 443 as alternatives for incoming connections.
