All of a sudden one day i found that one of my Blogs crashed while installing a plugin  saying “Allowed memory size exhauseted”

I quickly searched on Google and found that this error is caused by insufficient memory allocation in php.ini file. A standard server (linux box) setup comes with 8M memory and we need to increase this to avoid these types of errors.

Error:

Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 8192 bytes) in/home/orangecopper.com/wp-content

So i contacted my hosting company and they informed me that since i am on a shared hosting i had a limit on the amount of memory i can use. Initially i was a lil sad, but the limit was not bad !! the one i was using and crashing was 8 MB while the limit i could use was a comfortable 40 MB , for some host its 24 and some its commonly 32MB.

For those of you who use shared hosting the quick solution would be to add a line in .htaccess file located at your root folder OR creating a php.ini file in your root

SQL injection is a code injection technique that exploits a security vulnerability occurring in the database layer of an application. The vulnerability is present when user input is either incorrectly filtered for string literal escape characters embedded in SQL statements or user input is not strongly typed and thereby unexpectedly executed. It is an instance of a more general class of vulnerabilities that can occur whenever one programming or scripting language is embedded inside another. SQL injection attacks are also known as SQL insertion attacks.

Forms of vulnerability
Incorrectly filtered escape characters
This form of SQL injection occurs when user input is not filtered for escape characters and is then passed into an SQL statement. This results in the potential manipulation of the statements performed on the database by the end user of the application.

The following line of code illustrates this vulnerability:
statement = "SELECT * FROM users WHERE name = '" + userName + "';" Read the rest of this entry »

YOUR IP ADDRESS IS PUBLIC
Accessing the Internet is a security risk.

When you are connected to the Internet, an IP address is used to identify your
computer.  If you don’t protect yourself, this IP address can be used to access your
computer from the outside world.

A fixed IP address is a larger security risk.

If you’re using a modem with a dial-up connection, you will get a new IP
address every time you connect to Internet.

With an ADSL or cable connection users sometimes keep the same IP address for
several months, this represents an increased security risk.

If you have a fixed IP address, you give Internet hackers all the
time they need to search for entrances on your computer, and to store and share
(with other hackers) information they find on your computer.

Your Network Shares
Personal computers are often connected to a shared network. Personal
computers in large companies are connected to large corporate networks. Personal
computers in small companies are connected to a small local network, and
computers in private homes often share a network between family members.
