Network Security Problems are problems that are caused by users or by third-party software. In order to prevent this kind of security threats and attacks on networks, users should be careful and aware of the following:
1. Unauthorized Access
This is a major problem that affects all types of networks. Some settings in your network can be changed by unauthorized users, making it easy for them to access your network. The following are some common network security problems:
Network Access Control Issues – This is usually because of misconfigured or missing access control list (ACL). It is one of the most common network security problems. Because it allows unauthorized users to be able to access your network. Without a good ACL, it would be pretty easy for hackers to gain access to your network. The process of allowing and denying user access can be automated using a good ACL.
Traffic Spoofing – This is also another common problem that affects all types of networks. This is when packets are sent with fake IP addresses or incorrect addresses. Hence, results in the sender and recipient being switched around. As a result, the sender will send packets to an incorrect address. And the recipient will receive packets from an incorrect address causing confusion and disrupting data traffic flow.
2. Denial-of-Service (DoS) Attacks
A DoS attack can cause major damage to any type of organization. But it is often against large organizations such as banks, news organizations, government agencies, etc. A DoS attack consists of flooding servers with requests which will disrupt normal operations. Further, causing network problems or even shuts down operations temporarily. An example of a DoS attack is sending spam emails which may not seem like a big deal. But if each email has several recipients then you can imagine how many emails will have been sent. Further, resulting in network overloads and possibly even shut down operations temporarily.
3. Viruses, Worms, and Trojans
Network security problems can be by both users and third-party software. In order to prevent this kind of security threats and attacks on networks, users should be careful and aware of the following:
Viruses – A computer virus is a program that spreads without a user’s consent. This can be by attaching itself to your emails, word documents, web pages, etc. Once you open it or click on it, the virus will run in the background sending out more viruses from your computer to other computers causing network problems. A computer virus is a program that spreads without a user’s consent. This can be done by attaching itself to your emails, word documents, web pages, etc. Once you open it or click on it, the virus will run in the background sending out more viruses from your computer to other computers causing network problems.
2. Worms – A worm is also similar to a virus but with one major difference: worms spread without needing human intervention because they replicate themselves and distribute themselves across networks without human interaction, unlike viruses that need human interaction to spread. Worms are often as legitimate software applications or email attachments which makes them more dangerous than viruses because they don’t require human intervention in order to spread thus making them hard to detect.
3. Trojans – A Trojan horse is also a program that’s as legitimate software but once installed it will do something else other than what it claims that it’ll do such as stealing data or collecting personal information on users without their consent. Trojans are often run on Windows-based computers which means if you’re using Apple then you won’t have this problem unless you’re running Windows inside your Mac using virtualization tools like Parallels Desktop for Mac.
