There’s no question that network security is more important than it ever has been. Having a strong online presence is critical, as is having a powerful network. Whether a small, medium, or large business, you need to know your network is secure from outside attack. Unfortunately, there are many different ways that a network can be attacked, but by looking at the most common types, you will be better prepared to take the steps necessary to keep you and your company safe.
Be sure to ask your IT support company to pay extra special attention to your security needs and to implement as many safety measures as possible.
Denial of Service Network Attacks
This is by far and away the most common network attack, and one of the most insidious. Some estimates have this style of network security attack accounting for over a third of the total attacks that take place on the various service networks. Denial of Service is also commonly referred to as a DOS attack, and multiple computers are set up automatically to hit up the same vulnerable site or point again and again to flood their systems.
Brute Force Network Attacks
A brute force attack is just as it sounds. While many people imagine hackers cleverly going through hundreds of thousands of lines of code looking for a back door way in, and that certainly is one way of doing it, but the brute force attempt is an attempt to guess the password of a website through repeated attempts to force their way in.
There are multiple ways to deter a brute force attack and make it next to impossible for these to work. One is to have a good password. Having a good password isn’t just a case of combining letters, numbers, capital letters, and symbols. The longer and more complex you can make your password the better. A computer program will eventually guess a four character password, but 12 or 14? The possibilities become so large as to be mathematically ridiculous.
On top of that the next few steps you can take to protect yourself include:
- Blocking IP addresses that unsuccessfully try to log in repeatedly
- Blocking general IP addresses
- Having applications, that automatically lock out a person after so many failed attempts
Browser Network Attacks
A browser network attack is an attempt to take advantage of people who don’t update their computers by finding weaknesses in old browsers and developing software on websites that takes advantage of people using those browsers. The software gets in through a security flaw and can then attack the computer and any network system that it is attached to.
Backdoor Access Network Attacks
Backdoor attacks tend to be rare, but they are feared because when they take place, they are very targeted attacks that specifically focus on breaking into a targeted system to get to sensitive information or cause a severe disruption, or both. These account for only 2% of all computer network system attacks, but they are attacks that keep many security specialists up at night.
These are several of the most common network security attacks, and understanding the tactics and efforts up front will help any IT department or network security specialists prepare for any attack that comes your way.
