Are you worried about the network security of your company? If so, then it’s important to know some of the biggest threats.
Here are some of them:
- Browser Attacks
These attacks are done on people who are browsing the web. The attacks could encourage people to download malware that’s a fake software update/application. Malicious/compromised sites might also force malware on the systems of visitors. They do this by exploiting security weaknesses in the visitor’s browser/software. This is usually the result of the software being outdated.
One of the best steps your company can take to avoid this kind of attack is to update web browser and related services like Flash. This helps to make sure that new security vulnerabilities are patched before hackers can use them to attack networks.
- Backdoor Attacks
These make up a small percentage of network attacks but are worth noting. They’re a type of attack that gets around standard authentication. It then allows remote access. Backdoors are present in software based on the design. They can also be implemented by other software or launched by changing existing programs.
- SSL Attacks
This is another common attack on a network. The goal is to intercept data that’s sent over an encrypted connection. An attack that’s successful allows access to unencrypted data.
The attacks were quite common in late 2014. However, they’re still common today and account for a large percentage of all network attacks. There were several attacks following security vulnerabilities discovered in TLS and SSL.
- Brute Force Attacks
These kinds of attacks are increasing in in number and are done through automated software programs. They ”guess” various user passwords. The most network attacks are taking place in the US. That includes the number of attackers and targets.
This type of attack makes up about one-quarter of all attacks on networks. This type of attack tries to enter the “front door”, unlike many other attacks. The goal is to guess the password of a system.
Automated software is often used in order to guess thousands of password combinations. Sometimes this involves hundreds of thousands of combinations.
There are several ways you can protect your computers from these attacks. One basic way is to lock accounts after X login attempts. Another method is to block IP addresses after several login failures. Yet another option is to restrict login access to particular IP addresses.
- Shellshock Attacks
This is another common type of attack on networks. This is a vulnerability that’s found in the commend-line shell Bash. It’s used for Unix and Linux systems.
When Shellshock was discovered in September 2014, millions of systems/appliances were vulnerable. That included ones ranging from servers to thermostats. Since then attackers have started exploiting the various flaws. They use them to install malware that launches spam campaigns/DDoS attacks.
Many systems aren’t updated at all. So the vulnerabilities still exist over the web. The problem has become such a problem that Shellshock is the target of a large percentage of all network attacks. It’s become a major issue.
