A Beginner’s Guide to Network Security Threats

If you’re a stranger to network security, it’s time to catch up. Almost everyone has a home network these days, and most of us use it for activities like file sharing with software like Ares where security should be taken seriously. For those who work in tech fields, the need is even stronger. Here’s an overview of the most common security threats networks face.

Denial Of Service attack. This is one of the most common threats.A DOS is anything that prevents a device from providing normal services; it can even be physical, like cutting cables. Perhaps the most problematic type of DOS attack is the DDOS, or Distributed Denial Of Service, where giant botnets simply overwhelm the bandwidth capacity of a server. Coordinated DDOS attacks can take down large segments of communications infrastructure. As an end-user, you want to do your best to avoid becoming a bot by avoiding and removing malware. If you administrate a targeted network, you have even bigger problems.

Malware. This is the catch-all for spyware, adware, worms, trojans, and viruses -any software that unethically makes use of your computer against your will. Viruses infect your system using the files you’ve already got there; worms can make use of your network without needing your files. Trojans are typically executable files which come in and take over after you’ve downloaded them. Spyware and adware are less vicious, but still annoying, tracking your electronic behavior and advertising at you respectively.  If you use file sharing programs like Ares Galaxy, you need to make sure your security is set to a high level.

‘Man in the middle’. These attacks occur when someone intercepts encrypted communications, decrypts them, re-encrypts them, and passes them back along. This is relatively less common, and difficult to scale up, but the effects can be devastating if the intercepted information is important. Lastly, some of the hardest to combat attacks are from social engineering – for instance, when someone (usually pretending to have a legitimate reason, but not always) asks for whatever they need to know to bypass security protocols. No amount of protocol can make up for carelessness.
