With the myriad of source software available to hackers free of charge these days the world is an open market. You do not want to be an easy mark. So it’s good to know how multiple cyber-attacks operate. First let’s start with how to prevent DoS (denial of service) attacks. DoS are used to disrupt a service’s operations by overloading some link the chain of operation. An example would be overloading a network by using a program that sends so many communications or requests to the servers that nothing else can get through. In layman’s terms it’s having the phone off the hook. No one else can get through and business suffers accordingly. DoS attacks are malicious and usually prohibited by law in most countries. Signs that your network is under this kind of attack are the inability to use the internet, dramatically slow network speed, or a massive amount of spam email across the entire network, also called an email bomb. Some DoS attacks can max out your CPU usage, memory usage, and even start filling hard drive space. Properly maintained and updated routers, firewalls, and rate limiting switches can cut down on the impact of these attacks.

You will also want to prevent SQL injection attacks which is a much lower key cyber-attack. This attack occurs when code within the database of an application is modified by the hacker. It can wait like a land mine until the user of said application hits the correct keys authorizing it to “take action” sometimes with horrific results. The worst part of this is sometimes the victim of this attack will think they caused the problem even though it is the application interpreting their key strokes almost as HTML type code. SQL injection plays a shell game with the logic of the application and is difficult to reverse. The most proven way to prevent SQL injection is to black list any characters that can be significant in SQL. Be sure to learn about this to prevent this problem.

And last we will learn how to prevent cross site scripting (XSS) which is a security vulnerability that is heavily exploited. It is found in web applications and allows attacks to inject their script into web pages that are viewed by others. It’s the most common website vulnerability known. Scripts can be injected into web applications and intercept sensitive data from unaware clients using their cards to purchase a product. Scripts can also be used to navigate you to a website you did not intend to go to against your will. Scripts in webpages can even crash a client’s computer. Any smart business knows that you can build your security right into the web application to prevent cross site scripting, and that you should streamline the web applications to work with every possible web browser instead of a handful. Some web services are actually even more secure when using their patron browser. I hope this information is helpful in combating various cyber-attacks and will even help you prevent DoS.
